Remade for neutrality: every choice explained, project facts as parameters, scope boundaries linked both ways

1 Scope

NOTE This standard governs the selection, furnishing, and installation of finish hardware for swinging door openings where the hardware is specified and bought as its own package, apart from the door leaves and the frames. It is organized around the hardware schedule and its numbered hardware sets, and it covers the hanging, latching, locking, closing, holding, protecting, sealing, and electrifying of the opening. (1.1)
1.2 The furnished work shall comprise every hardware item the hardware schedule assigns to an opening, the cylinders and keys, the fasteners and templates for that hardware, the power transfer devices and the electrified hardware at the opening, and the installation and adjustment of all of it.
NOTE The leaves and the frames are separate subjects. Hollow metal doors and frames, with their factory reinforcement for this hardware, are governed by Exterior Doors And FramesHollow Metal Doors and FramesResolves to the current adopted revision.sync/exterior-doors-and-frames. Wood leaves, with their machining, blocking, and raceway, are governed by Wood DoorsWood DoorsResolves to the current adopted revision.sync/wood-doors. Where the door, the frame, and the hardware are bought together as one coordinated supply, Doors Frames And HardwareDoors, Frames, and HardwareResolves to the current adopted revision.sync/doors-frames-and-hardware applies in place of this standard. (1.3)
NOTE Electrified hardware furnished under this standard stops at the opening. The controllers, credential readers, request-to-exit devices, door position switches, power supplies, cabling, and programming that decide who may pass are governed by Access Control SystemsAccess Control SystemsResolves to the current adopted revision.sync/access-control-systems, and the fire alarm control unit and the release circuit that drops hold-open devices and electrified locks on alarm are governed by Fire Alarm SystemsFire Alarm SystemsResolves to the current adopted revision.sync/fire-alarm-systems. (1.4)
NOTE All-glass swing doors hung in interior glass partitions take their patch fittings, rails, pivots, locks, and closers from this standard. The tempered or laminated panel of that door, its thickness, and its edge work are governed by Interior GlazingInterior Glazing and Glass PartitionsResolves to the current adopted revision.sync/interior-glazing. Frameless all-glass entrance assemblies furnished as a system, the glass panels together with their fittings and closers, are governed by All Glass EntrancesAll-Glass Entrances and DoorsResolves to the current adopted revision.sync/all-glass-entrances. (1.5)
NOTE Low-energy power-operated and power-assist swing door operators are hardware on the opening and are specified here with the closers they replace. Full-energy automatic entrances that open on approach, with their operators, sensors, and guide rails, are governed by Automatic Entrance DoorsAutomatic Entrance DoorsResolves to the current adopted revision.sync/automatic-entrance-doors. Detention, ballistic, blast, and forced-entry-rated hardware has no standard in this library and is specified by project-specific engineered design outside this standard. (1.6)
1.7 The Contractor shall reconcile the hardware schedule against the door schedule, the frame submittal, and the door submittal before any hardware is procured and before any frame is released for fabrication.
NOTE Frame preparation for hinges, strikes, closers, and exit devices is punched and reinforced at the factory from the hardware templates. A hardware change discovered after the frames are built means field welding on a labeled frame, a replacement frame, or a non-conforming opening, which is why the reconciliation sits ahead of procurement rather than ahead of installation. (1.8)
1.9 Where a requirement of this standard and a requirement of the door or frame standard both address the same component at one opening, the Architect shall resolve the conflict in writing before the component is fabricated.

2 Referenced Standards

2.1 Hardware, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited.
2.2 Where referenced standards conflict, the more stringent requirement shall govern unless the Architect directs otherwise in writing.
2.3 Hardware at fire-rated openings shall comply with the edition of the fire test standard under which the door assembly is listed, and Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code governs which opening protective rating and which egress provisions apply at each opening.

4 Quality Assurance

4.1 Authorship of the Hardware Schedule

4.1.1 The hardware schedule and the hardware sets shall be prepared by the party indicated in the datasheet.
Hardware Schedule Preparerselect
Architectural Hardware Consultant holding a current DHI certification
Hardware supplier's consultant with a record of comparable projects
The Architect's hardware specifier
4.1.2 Where the preparer is a consultant to the hardware supplier, the preparer shall have prepared hardware schedules for not fewer than five completed projects of comparable opening count and shall submit that record.
4.1.3 The preparer shall hold the hardware schedule and the hardware sets consistent with the door schedule, the keying schedule, and the electrified opening wiring diagrams through every revision until final acceptance.
NOTE A DHI-certified consultant is examined on the code, the listings, and the templates, which is the expertise a project with rated pairs, electrified openings, and a master key system is buying, at a fee. A supplier's consultant prepares the schedule from the products the supplier stocks, at no separate fee, which fits a project whose openings are few and alike. The Architect's own specifier keeps the authorship inside the design contract and carries the coordination burden with it. The decision follows the opening count, the share of electrified and rated openings, and whether the Owner's key system already exists. (4.1.4)

4.2 Supplier and Installer Qualifications

4.2.1 The hardware supplier shall be a firm that furnishes architectural hardware for projects of comparable opening count as a regular part of its business and that stocks the products furnished for replacement.
4.2.2 Electrified hardware shall be installed and terminated by an installer trained by the manufacturer of the device installed, and the installer's training record shall be submitted before the work begins.
4.2.3 Hardware at fire-rated openings shall be installed by personnel familiar with NFPA 80, and the installer shall be able to produce the listing for every item at a rated opening on request.

4.3 Pre-Installation Conference

4.3.1 Before any frame is set, the Contractor shall convene a conference attended by the hardware supplier, the hardware installer, the door and frame installers, the electrical contractor, the access control installer, and the fire alarm installer, and shall record its decisions.
4.3.2 The conference shall confirm, for every electrified opening, the device, the fail mode, the power transfer, the raceway path, the power supply location, and the fire alarm release point.
NOTE An electrified opening involves five trades and a listing, and every one of them has to agree on the same drawing before the frame goes in. The conference is where a strike drawn on the wrong jamb or a hold-open with no alarm relay is found while fixing it costs a pen stroke. (4.3.3)

5 Hardware Sets and the Hardware Schedule

5.1 Hardware shall be organized into numbered hardware sets, each set listing every item an opening type requires, and every opening on the door schedule shall be assigned exactly one set.
5.2 The hardware set assigned to each opening shall be as stated on the door schedule.
5.3 Each hardware set shall be verified by the preparer against the leaf material, leaf thickness, leaf weight, hand, swing, fire-protection rating, smoke-control listing, sound rating, and egress function of every opening assigned to it before the set is released for procurement.
5.4 The hardware schedule format shall be as indicated in the datasheet.
Hardware Schedule Formatradio
● Vertical format, listing each set once with the openings it serves
○ Horizontal format, listing each opening with its items across one line
NOTE A vertical schedule lists every item in a set once and names the openings the set serves, so a change to the set is made in one place, and it is the format the hardware industry reviews against. A horizontal schedule lists each opening on its own line with its items across it, which reads directly against a door schedule and grows one line per opening, so a change to a set is repeated on every line that carries it. (5.5)
5.6 The hardware sets shall list each item by its ANSI/BHMA standard and grade, its function designation, its size, its finish code, its fastening, and its quantity per opening, and shall name the manufacturer designation of the product furnished.
5.7 Hardware shall be furnished from as few manufacturers as the set requirements allow, so that keying, finish, and template dimensions remain consistent across the work.
5.8 Where an item within a set is not manufactured in the finish, function, or size the set requires, the supplier shall submit the proposed substitution for review before the item is ordered rather than furnishing the nearest available product.
5.9 Fasteners shall be furnished with each item by its manufacturer, of the material class and finish of the item they fasten, with machine screws into every steel reinforcement and through-bolts where the leaf construction or the listing requires them.
NOTE Wood screws into a reinforcement plate strip, and a self-drilling screw into a lock block splits it. The fastener is part of the listing at a rated opening, which is why it is furnished by the hardware manufacturer and not substituted from site stock. (5.10)

6 Operational Grades

NOTE The ANSI/BHMA grade is a test result. Each A156 product standard assigns a grade from the cycle, strength, security, and finish tests the product survives, so a grade names a tested performance and not a price tier. A Grade 1 bored lock completes one million cycles under ANSI/BHMA A156.2, a Grade 2 lock eight hundred thousand, and a Grade 3 lock two hundred thousand; a Grade 1 closer completes two million cycles under ANSI/BHMA A156.4 against one million at Grade 2 and five hundred thousand at Grade 3. At an opening cycled a few hundred times a day the grades differ by years of service before the first rebuild; at an opening cycled a dozen times a day they differ by the price, and the lower grade at that opening buys the same service life. The grade selected here is the floor for the project, and the hardware schedule raises it at any opening whose traffic warrants it. (6.1)
6.2 The minimum grade for hinges shall be as indicated in the datasheet.

6.6 Where the hardware schedule assigns a higher grade at an opening than the project minimum, the hardware schedule governs that opening.

7 Hinges and Pivots

7.1 Butt hinges shall conform to ANSI/BHMA A156.1 and to the template dimensions of ANSI/BHMA A156.7, continuous hinges to ANSI/BHMA A156.26, and self-closing hinges and pivots to ANSI/BHMA A156.17.
7.2 The hanging device used as the project standard at swinging openings shall be as indicated in the datasheet, and the hardware schedule governs any opening it assigns a different device.
Project Standard Hanging Deviceselect
Full mortise butt hinge
Half mortise butt hinge
Full surface butt hinge
Half surface butt hinge
Continuous geared hinge
Continuous pin-and-barrel hinge
Center-hung pivot set
Offset pivot set
Spring hinge, self-closing
NOTE A butt hinge carries the leaf at two, three, or four points on the stile and is the device every frame and leaf is prepared for by default. A continuous hinge spreads the load along the full height, which is why it appears at high-cycle openings, at leaves that have torn out a butt hinge once, and at exterior leaves where its stiffness also resists prying; it costs more and it covers the hinge stile so the leaf cannot be removed without removing the hinge. A pivot carries the load into the floor and the head instead of the jamb, which is what makes it the device for a very heavy or a very wide leaf and for a leaf that swings both ways. A spring hinge closes a light leaf without a closer and without closer control, so the leaf slams at one spring setting and fails to latch at the next. Surface and half-surface hinges serve leaves and frames that cannot be mortised, including existing openings and channel frames. (7.3)
7.4 The hinge bearing type shall be as indicated in the datasheet.
Hinge Bearing Typeselect
Ball bearing
Concealed anti-friction bearing
Plain bearing
NOTE A plain bearing rides steel on steel and wears a leaf out of alignment at any opening that carries a closer. A ball bearing hinge carries the thrust on raceways and is the bearing a closer-equipped opening is specified with, and a concealed anti-friction bearing gives the same service with no visible bearing rings. (7.5)
7.6 The base material of hinges at interior openings shall be as indicated in the datasheet.
Hinge Base Material at Interior Openingsselect
Steel, plated
Stainless steel
Brass or bronze
7.7 The base material of hinges at exterior openings and at openings exposed to washdown or sustained high humidity shall be as indicated in the datasheet.
Hinge Base Material at Exterior and Wet Openingsselect
Stainless steel
Brass or bronze
Steel, plated
NOTE A plated steel hinge is the lowest-cost base and holds its finish indoors; outdoors or under washdown its plating breaks at the knuckle and the steel beneath rusts, which stains the leaf below the hinge. Stainless steel and brass or bronze carry the finish through their thickness. Brass and bronze are softer and are selected for their color, and stainless matches the 630 finish family. (7.8)
7.9 Hinges at fire-rated openings shall be of steel or stainless steel base material unless the hinge is listed for use on a fire door assembly, and shall be of a size and quantity within the assembly listing.
7.10 Hinge quantity shall be not fewer than two on a leaf up to 60 in. tall and not fewer than three on a leaf over 60 in. tall, plus one additional hinge for each 30 in. or fraction of leaf height over 90 in.
7.11 Hinge height shall be 4-1/2 in. on a 1-3/4 in. thick leaf up to 3 ft 0 in. wide, 5 in. on a 1-3/4 in. thick leaf over 3 ft 0 in. wide, and 3-1/2 in. on a 1-3/8 in. thick leaf, and the hinge width shall clear the trim, the frame face, and any wall return the leaf must swing past.
7.12 Heavy-weight hinges, in the heavy-weight gauge ANSI/BHMA A156.1 assigns to the hinge size, shall be furnished where the leaf exceeds 200 lb or the opening is scheduled as high-frequency, and standard-weight hinges, in the standard-weight gauge for the size, at other openings.
NOTE A standard-weight 4-1/2 in. hinge carries a 1-3/4 in. leaf of ordinary weight at ordinary traffic. At an entrance, a corridor cross door, or a classroom, the hinge sees several hundred cycles a day with a closer pulling on it at every one, and the thicker heavy-weight hinge leaf is what keeps the knuckle from wearing oval and the leaf from sagging onto the strike. The leaf weight comes from the door submittal, which is one of the reasons the schedule is reconciled against it. (7.13)
7.14 Hinges at outswinging exterior openings and at openings serving secured spaces shall be furnished with the pin security indicated in the datasheet.
Pin Security at Outswinging Exterior and Secured Openingsselect
Non-removable pin with a set screw
Security stud interlocking the hinge leaves
Continuous hinge presenting no removable pin
NOTE A set screw in the barrel keeps the pin from being driven out while the leaf is closed; a security stud leaves the pin removable but locks the two hinge leaves together so the door stays hung without it; a continuous hinge has no exposed pin to attack. The set screw is the lowest-cost measure and is defeated only by cutting the knuckle; the stud is selected where the pin has to come out for leaf removal; the continuous hinge is selected where the opening is also high-cycle. (7.15)
7.16 Center-hung and offset pivot sets shall be furnished with an intermediate pivot where the pivot manufacturer's published limits for leaf height and weight require one, and the pivot set shall be rated by its manufacturer for the leaf weight stated on the door submittal.
7.17 Spring hinges shall not be furnished at a fire door assembly unless they are listed for that use, and a spring-hinged leaf shall meet the closing time required under the Accessible Opening Requirements section of this standard.
7.18 Continuous hinges at fire-rated openings shall be listed for the rating period and installed with the fasteners and at the spacing the listing names.

8 Locksets, Latches, and Trim

8.1 Bored locksets and latches shall conform to ANSI/BHMA A156.2, mortise locksets and latches to ANSI/BHMA A156.13, interconnected locks to ANSI/BHMA A156.12, and auxiliary locks to ANSI/BHMA A156.36.
8.2 The lockset chassis type used as the project standard shall be as indicated in the datasheet, and the hardware schedule governs any opening it assigns a different chassis.
Project Standard Lockset Chassisselect
Bored cylindrical lockset
Mortise lockset
Interconnected lockset
Tubular lockset
NOTE A mortise case sits in a pocket cut into the stile and carries the latch, a deadbolt, an auxiliary latch, and the lever mechanism in one housing, which is what lets it offer functions a bored lock cannot and what makes it the heavier chassis at a high-abuse opening; it needs a leaf whose stile is solid through the pocket. A bored lock passes through two holes, installs in minutes, replaces without a locksmith, and asks less of the leaf's edge. An interconnected lock pairs a bored latch with a bored deadbolt so one lever retracts both, which is how a deadbolt is put on an egress door without a second motion. A tubular lock is the light-duty chassis and serves closets and residential interiors. (8.3)
8.4 The lock trim style shall be as indicated in the datasheet.
Lock Trim Styleselect
Lever handle
Lever handle with a return to the leaf face
Knob
Thumbpiece with escutcheon
Push-pull paddle trim
NOTE A lever is operable with a closed fist and is the trim the accessibility standard describes. A return-to-door lever brings the lever end back toward the leaf face, so a sleeve or a wheelchair armrest slides off it rather than catching, which is the reason it is scheduled in healthcare and in schools. A knob cannot meet the accessible operating requirement and is selected only at openings off the accessible route. A thumbpiece escutcheon reads as a grip handle and is selected for its appearance at an entrance. Paddle trim is operated by pushing or pulling with a forearm, a hip, or a cart, and serves healthcare and food service openings where hands are full or gloved. (8.5)
8.6 A knob shall not be furnished at an opening on an accessible route regardless of the datasheet selection.
8.7 The lock backset shall be as indicated in the datasheet.
Lock Backsetrange
in
2.3752.753.755
8.8 The backset shall be increased at any opening where the standard backset would place the trim against the frame stop, an adjacent wall, or a pull on the opposite face, and the increased backset shall be confirmed against the leaf's edge construction before the leaf is machined.
8.9 The lock function at each opening shall be as stated on the hardware schedule by its ANSI/BHMA function designation, selected to the security, privacy, and egress obligations of the space the opening serves.
NOTE A function describes which side latches, which side locks, and what unlocks it. A passage function latches and never locks; a privacy function locks from inside with a turn and releases from outside with a tool; an office function locks from inside and opens with a key; a classroom function locks and unlocks by key from the corridor; a storeroom function is locked from outside at all times and free from inside at all times; a classroom security function adds an inside key cylinder so the room is locked from within. The function is a room decision and not a door-type decision, which is why it is stated opening by opening on the schedule. (8.10)
8.11 A door in a means of egress shall be openable from the egress side without a key, a tool, special knowledge, or special effort, and the latch and any lock shall release with the number of releasing motions Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code permits for the occupancy served, except where a controlled, delayed, or sensor-released egress arrangement is installed in full compliance with the provision of that code that permits it.
8.12 Auxiliary deadbolts shall not be furnished on a door in a means of egress unless the deadbolt is retracted by the same motion that retracts the latch or the building code expressly permits a separate deadbolt at that opening.
NOTE Locking a means of egress door against the direction of travel is one of the few things a specification can do that kills people. Every controlled, delayed, and sensor-released egress arrangement the code allows carries a list of conditions, and all of them have to be satisfied together, not selectively, at every opening that uses it. (8.13)
8.14 Strikes shall be furnished with a strike box at every frame preparation, with a curved lip of a length that clears the frame face and does not project into the path of travel, and the strike at a fire-rated opening shall be the strike the listing names.
8.15 Latchbolt throw at a fire-rated opening shall be not less than 1/2 in. at a single leaf and not less than 3/4 in. at a pair, or the longer throw the assembly listing names.
8.16 Lever trim shall be through-bolted or secured to the chassis so that the trim cannot be pulled from the leaf, and a return-to-door lever shall return to within 1/2 in. of the leaf face.

9 Cylinders and Keying

9.1 Cylinder Format

9.1.1 Cylinders and input devices shall conform to ANSI/BHMA A156.5, high-security cylinders shall additionally conform to ANSI/BHMA A156.30, and the keying system shall follow the practices of ANSI/BHMA A156.28.
9.1.2 The cylinder format used throughout the project shall be as indicated in the datasheet.
Cylinder Formatselect
Conventional fixed cylinder
Small format interchangeable core
Large format interchangeable core
Removable core in a proprietary format
9.1.3 Every keyed device on the project, including the exit device trim, the removable mullions, and the key switches furnished under this standard, shall accept the cylinder format selected, so that one core inventory serves the building.
NOTE An interchangeable core comes out with a control key and goes back in without disassembling the lock, so rekeying a building is a walk-through with a bag of cores instead of a locksmith at every door. The small format fits one housing across every manufacturer that makes it, which lets the Owner change lock brands and keep the cores; the large format carries more pins and more key changes but is proprietary to each maker. A conventional cylinder is the lowest cost at purchase and is rekeyed by pulling the lock. The control key becomes the most security-sensitive key in the building under any interchangeable format. (9.1.4)

9.2 Keyway Control

9.2.1 The keyway control level shall be as indicated in the datasheet.
Keyway Control Levelselect
Standard open commercial keyway
Restricted keyway with patented key control
High-security keyway conforming to ANSI/BHMA A156.30
The Owner's existing keyway extended to this project
9.2.2 Where the Owner operates an existing key system at this or another facility, the Owner shall confirm in writing whether this project joins that system before cylinders are ordered, and the cylinder format and keyway shall then match the existing system.
NOTE An open keyway means blanks are sold to any locksmith, so any key can be copied by anyone holding it. A patented keyway restricts the blanks to authorized channels for the life of the patent, which is what makes a "do not duplicate" stamp enforceable rather than advisory. A high-security cylinder adds measured resistance to picking, drilling, and bumping on top of the restricted blank. Joining an existing system inherits whatever control that system has, and a core format that differs from the Owner's existing cylinders forces a facility-wide rekey, which is rarely intended and always costly. (9.2.3)

9.3 Keying System Hierarchy

9.3.1 The keying system hierarchy shall be as indicated in the datasheet.
Keying System Hierarchyselect
Keyed alike throughout
Keyed different, with no master keying
Master key system
Grand master key system
Great grand master key system
The Owner's existing key system extended to this project
9.3.2 The keying system shall be designed by the hardware schedule preparer in a keying conference with the Owner, and the keying schedule shall be accepted by the Owner in writing before cylinders are ordered.
9.3.3 The keying system shall have theoretical key change capacity for the openings on this project plus the expansion the Owner identifies at the keying conference, and the preparer shall state that capacity on the keying schedule.
NOTE Each level of master keying adds a shear line to every cylinder in the system, which enlarges the set of key cuts that will turn a given lock and spends key change capacity. A hierarchy deeper than the building's departmental structure buys no operational benefit and costs both security margin and expansion room. A specification that leaves the keying to be worked out during submittals hands the design of the Owner's key system to the contractor, who does not know the Owner's departments. (9.3.4)

9.4 Construction Keying

9.4.1 The construction keying method shall be as indicated in the datasheet.
Construction Keying Methodselect
Temporary construction cores replaced at Owner acceptance
Construction master keying within the permanent cylinders
Permanent cylinders installed at the outset
Owner-furnished temporary cylinders
9.4.2 Where temporary cylinders or cores are furnished, the Contractor shall replace them with the permanent cylinders keyed to the accepted keying schedule at Owner acceptance, in the Owner's presence or against the Owner's written release.
9.4.3 The Contractor shall collect every construction key and every temporary core from the trades and shall account for them in writing before the permanent cylinders are installed, and shall rekey at the Contractor's cost any cylinder whose construction key cannot be accounted for.
NOTE A temporary core is pulled and discarded, so nothing cut during construction operates the finished building. Construction master keying leaves the permanent cylinder in place and voids the construction key by a one-time operation of the change key, which is the lower-cost method with conventional cylinders and the one that leaves a residual cut in the cylinder. Permanent cylinders from the outset are selected where the Owner takes control of the building floor by floor. (9.4.4)

9.5 Key Quantities and Key Control

9.5.1 The number of change keys furnished for each keyed cylinder or core shall be as indicated in the datasheet.
Change Keys per Cylinderrange

NOTE Two keys per change is the quantity every manufacturer ships, and more are cut at the Owner's request against the key record. The master and control quantities follow how many people carry a master and how the Owner stores the control key, and no one count is the norm. (9.5.3)
9.5.4 Keys shall be stamped with the key symbol from the keying schedule and shall not be stamped with the opening number or any text identifying the space they operate.
NOTE Stamping a room number on a key turns a lost key into a map. The key symbol identifies the key to the person holding the keying schedule and to nobody else. (9.5.5)
9.5.6 The Contractor shall furnish a key control cabinet sized for the keys the accepted keying schedule generates, with tags, hooks, and an index.
9.5.7 Keys, cores, and the key bitting list shall be delivered directly to the Owner's designated representative against a signed receipt, and shall not be routed through the site office or left at an installation area.

10 Exit Devices

10.1 Exit devices shall conform to ANSI/BHMA A156.3 and shall be listed as panic hardware under UL 305, and devices at fire-rated openings shall be listed as fire exit hardware for the rating period of the assembly.
10.2 Panic hardware or fire exit hardware shall be furnished at every opening Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code requires to have it, including doors serving a Group H occupancy, doors serving a room or space with an occupant load of 50 or more in a Group A or Group E occupancy, and the electrical equipment room doors the referenced electrical code requires to have it.
10.3 Whether the device at each opening is furnished as panic hardware or as fire exit hardware shall follow the fire-protection rating of that opening, with fire exit hardware at every fire-rated opening and panic hardware at every other opening.

Derived — the fire-protection rating of the opening on the door schedule (by default)
10.4 The exit device chassis type used as the project standard shall be as indicated in the datasheet, and the hardware schedule governs any opening it assigns a different chassis.
Project Standard Exit Device Chassisselect
Rim device
Mortise device
Surface vertical rod device
Concealed vertical rod device
Concealed vertical cable device
NOTE A rim device mounts on the face and latches into a strike on the frame or a mullion, so it fits any leaf, replaces without machining, and is the device most frames are prepared for. A mortise device puts the latch in the leaf edge and offers the functions of a mortise lock, at the cost of a solid stile and a mortise preparation. A vertical rod device latches at the head and, where the bottom rod is furnished, at the floor, which is what secures the inactive leaf of a pair with no mullion; the surface version is visible and serviceable from the face, the concealed version runs inside the leaf and needs a leaf built for it. A concealed cable device replaces the rods with a cable and a single top latch, so there is no bottom rod to be kicked out of adjustment. (10.5)
10.6 The actuating member of the device shall be as indicated in the datasheet.
Exit Device Actuating Memberradio
● Touchpad
○ Crossbar
NOTE A crossbar spans the leaf on pivots and is the historic form; a touchpad is a push rail flush to the device body, takes no grasp to operate, and leaves nothing projecting for a sleeve or a cart to catch. (10.7)
10.8 The dogging provision on panic hardware at non-rated openings shall be as indicated in the datasheet.
Dogging on Panic Hardwareselect
No dogging
Hex-key mechanical dogging
Cylinder dogging
Electric dogging by latch retraction
NOTE Dogging holds the latch retracted so the leaf works as a push-pull door during business hours. A hex key dogs any device and anyone holding the key can dog it; cylinder dogging puts a keyed cylinder on the operation so only a keyholder can leave the opening unlatched; electric latch retraction dogs the device from the access control schedule and releases it on command, which is what lets an automatic operator or a remote unlock work with an exit device. (10.9)
10.10 Fire exit hardware shall not be furnished with mechanical dogging, and electric latch retraction on fire exit hardware shall be arranged so that the latch projects on activation of the fire alarm system and on loss of power.
10.11 The exit device features furnished at the openings the hardware schedule assigns them to shall be as indicated in the datasheet.
Exit Device Features Furnishedcheckbox
☐ Exit alarm conforming to ANSI/BHMA A156.29
☐ Latchbolt monitor switch
☐ Request-to-exit switch in the touchpad
☐ Cylinder-operated outside trim
☐ Less-bottom-rod configuration with an auxiliary fire pin at rated pairs
10.12 The outside trim function at each device shall be as stated on the hardware schedule, and the trim shall be listed for use with the device it operates.
10.13 The force to release the latch shall not exceed 15 lbf applied in the direction of egress travel, and the actuating portion of the device shall be mounted not less than 34 in. and not more than 48 in. above the finished floor.
10.14 The actuating portion shall extend not less than one-half the clear width of the leaf.
10.15 No lock, latch, chain, or other device shall be installed on a door carrying panic hardware or fire exit hardware that prevents the leaf from opening on operation of the device, other than the electrified arrangements the building code permits and the Electrified Hardware section of this standard describes.
10.16 Where a bottom rod is furnished, the floor strike shall be set flush with the finished floor and located out of the accessible route, and where the bottom rod is omitted at a fire-rated pair, the device shall carry the auxiliary fire pin the listing names.
NOTE A bottom rod places a strike in the path of every mop, every cart wheel, and every shoe that crosses the opening, and the rod falls out of adjustment as the leaf settles. A less-bottom-rod device removes the floor strike by relying on the top latch alone, and at a rated pair it carries a thermal pin that projects into the opposite leaf when the pin's fusible element lets go, which is what keeps the pair from bowing apart in a fire. (10.17)

11 Door Closers and Hold-Open Devices

11.1 Door closers shall conform to ANSI/BHMA A156.4, overhead holders to ANSI/BHMA A156.8, and electromagnetic release and hold-open devices to ANSI/BHMA A156.15, and closers and hold-open devices at fire-rated openings shall be components covered by the fire door assembly listing.
11.2 Every fire door assembly and every smoke and draft control assembly shall be furnished with a closer or a self-closing device that closes and latches the leaf from any open position.
11.3 The closer mounting class used as the project standard shall be as indicated in the datasheet, and the hardware schedule governs any opening it assigns a different class.
Project Standard Closer Mounting Classselect
Surface-mounted on the leaf face
Surface-mounted in the frame soffit
Concealed in the leaf
Concealed in the frame head
Floor-mounted closer with pivots
NOTE A surface closer is reached with a screwdriver from a ladder, which is why it survives twenty years of adjustment; the parallel-arm mounting on the push face keeps the arm inside the room and out of reach, and the regular-arm mounting on the pull face is the most efficient and the most visible. A soffit mount clears the leaf face for a lite or a sign. A concealed closer disappears into the leaf or the head and takes the leaf off its hinges to service, so an opening that will be readjusted often is the one where concealment costs the most. A floor closer carries a heavy or a double-acting leaf on pivots and holds the closer under the threshold. (11.4)
11.5 The arm configuration at each opening shall be as stated on the hardware schedule to suit the mounting face and the stop condition of that opening, rather than selected project-wide.
11.6 The adjustable features required on closers shall be as indicated in the datasheet.
Closer Adjustable Features Requiredcheckbox
☑ Adjustable backcheck
☑ Separately adjustable sweep and latch speeds
☑ Adjustable spring power across the size range
☐ Delayed action
☐ Cush arm with an integral dead stop
☐ Spring cush arm
NOTE Backcheck slows the leaf in the last part of the opening arc so a leaf thrown open does not strike the wall or tear the closer off the leaf. Separate sweep and latch valves let the leaf close slowly through its travel and still accelerate to latch, which is how the accessible closing time and reliable latching are met together. Adjustable spring power lets one closer body be set from the lightest interior setting to the force an exterior leaf needs, so one model serves the project and the installer sets the force at the opening. Delayed action holds the leaf near fully open for a settable interval before the sweep begins, which gives a person with a cart or a walker time to pass. A cush arm stops the leaf in the arm and spares the wall where no stop can be mounted, at the cost of loading the leaf's top rail with every stop. (11.7)
11.8 Closer spring power at each opening shall be selected from the manufacturer's published sizing for the leaf width, the mounting, and the exposure, and shall be set to the lowest value that closes and latches the leaf against the gasketing and the pressure conditions at that opening.
11.9 Backcheck shall not be furnished as a substitute for a door stop where a stop is required to protect a wall, a window, or equipment within the swing.
11.10 The hold-open method used as the project standard at openings that are to stand open in normal use shall be as indicated in the datasheet.
Project Standard Hold-Open Methodselect
No hold-open
Hold-open arm on the closer
Overhead surface holder
Overhead concealed holder
Wall-mounted or floor-mounted magnetic holder with the closer
Electromagnetic closer-holder released by the fire alarm system
NOTE A hold-open arm or an overhead holder parks the leaf mechanically and is released by hand, which is what makes it unusable at a rated opening. A magnetic wall holder works with any closer and releases on loss of power to the magnet, so it is released by the fire alarm; it needs a wall within the swing and backing behind it. An electromagnetic closer-holder puts the holder in the closer body and is released the same way, with no wall required and with an integral smoke detector where the listing provides one. (11.11)
11.12 A hold-open arm, an overhead holder, or any other hold-open device that is not released by the fire alarm system shall not be furnished on a fire door assembly or on a smoke and draft control assembly.
11.13 Hold-open devices at fire door assemblies and at smoke and draft control assemblies shall be electromagnetic devices listed under UL 228 or ANSI/BHMA A156.15, released as described under the Fire Alarm Release article of this standard.
11.14 Closers at accessible openings shall be adjusted to the closing time and the opening force stated under the Accessible Opening Requirements section of this standard.

12 Low-Energy Power Operators

12.1 Low-energy power-operated and power-assist operators on swing doors shall conform to ANSI/BHMA A156.19, and an operator at a fire door assembly shall be listed as a closing device for use on a fire door assembly.
NOTE A low-energy operator opens a swing door only on a knowing act, at a speed and a force ANSI/BHMA A156.19 limits so that the leaf can meet a person without injuring them, which is why it needs no approach sensor and why it is scheduled with the finish hardware of the opening it serves. A full-energy entrance opens on approach and carries the sensors and guide rails that make that safe; it is a different product under ANSI/BHMA A156.10 and is governed by Automatic Entrance DoorsAutomatic Entrance DoorsResolves to the current adopted revision.sync/automatic-entrance-doors. (12.2)
12.3 The operator class at the openings the hardware schedule assigns a power operator to shall be as indicated in the datasheet.
Power Operator Classradio
● Low-energy power-operated, opening fully on a knowing act
○ Power-assist, reducing the manual opening force
NOTE A low-energy power-operated door opens fully when the actuator is pressed and closes on its own, so a person using a wheelchair passes without touching the leaf, and it is the operator an accessible entrance or a corridor cross door is scheduled with. A power-assist door only lightens the push on the leaf; the person still opens it, and it serves an opening where a full power swing into a corridor or a lobby is unwanted. (12.4)
12.5 The operator drive shall be as indicated in the datasheet.
Power Operator Driveradio
● Electromechanical
○ Electrohydraulic
NOTE An electromechanical operator drives the arm through a motor and a gear train and closes by spring, and is the drive most low-energy operators use. An electrohydraulic operator pairs the motor with a hydraulic closer body and closes with closer-type control, which holds its closing speed through a wider temperature range at an exterior leaf. (12.6)
12.7 The operator mounting shall be as indicated in the datasheet.
Power Operator Mountingselect
Surface-mounted on the push face with a parallel arm
Surface-mounted on the pull face with a regular arm
Concealed overhead in the frame head
NOTE A push-face mounting keeps the arm on the side the leaf swings toward and is the mounting a corridor or an out-swinging entrance takes; a pull-face mounting puts the arm on the side the leaf swings away from and is the more efficient geometry where the frame soffit is clear; a concealed operator disappears into a frame head built deep enough to take it and is serviced by removing the head cover. The mounting follows the swing, the stop condition, and the frame depth at each opening, which is why no one mounting is the norm. (12.8)
12.9 The knowing-act actuators furnished at each power-operated opening shall be as indicated in the datasheet.
Knowing-Act Actuators Furnishedcheckbox
☑ Wall-mounted push plate
☐ Bollard-mounted push plate
☐ Wireless push plate
☐ Touchless wave sensor
☐ Push-and-go operation from the leaf
☐ Key switch
☐ Release from the access control system
NOTE A push plate is the plainest knowing act and the one every person recognizes; a wireless plate avoids a conduit to a bollard or a glass wall. A wave sensor reads a hand held near it and is selected where hands are gloved, full, or kept off surfaces, at the cost of occasional false actuation from passing traffic. Push-and-go starts the operator when the leaf is pushed a few degrees by hand, so there is no actuator to find, and it suits a leaf that is also used manually all day. A key switch or an access control release confines the operated opening to the people it is intended for. (12.10)
12.11 The operator shall open and close the leaf within the speed, time, kinetic energy, and force limits of ANSI/BHMA A156.19, and the force required to stop the leaf at any point of its travel shall not exceed 15 lbf.
12.12 On loss of power, the operator shall allow the leaf to be opened manually and to close under its spring, within the manual operating forces ANSI/BHMA A156.19 permits with power off.
12.13 Actuators shall be located outside the arc of the swing where a person operating them stands clear of the moving leaf and within view of the opening, and shall be mounted at the height the Accessible Opening Requirements section of this standard states for operable parts.
12.14 Each power-operated leaf shall carry, on both faces, the signage ANSI/BHMA A156.19 requires for the operator class furnished.
12.15 At a latched opening, the operator shall be furnished with an electric strike, an electrified lock, or electric latch retraction from the Electrified Hardware section of this standard, interlocked so that the latch is released before the operator begins to open the leaf.
12.16 An operator at a fire door assembly or a smoke and draft control assembly shall close and latch the leaf, and its actuators shall be disabled, on activation of the fire alarm system and on loss of power, through the release described under the Fire Alarm Release article of this standard.
12.17 The Contractor shall coordinate a dedicated 120 V branch circuit to each operator location with the electrical work, and the operator, its actuators, and the low-voltage wiring between them shall be furnished under this standard.

13 Door Stops and Silencers

13.1 Door stops and auxiliary hardware shall conform to ANSI/BHMA A156.16, and overhead stops to ANSI/BHMA A156.8.
13.2 A stop shall be furnished at every opening where the leaf, its trim, or its hardware would otherwise strike a wall, a window, a casework unit, or adjacent equipment within the full arc of the swing.
13.3 The stop type used as the project standard shall be as indicated in the datasheet.
Project Standard Door Stopselect
Wall-mounted bumper stop
Floor-mounted dome stop
Overhead concealed stop
Overhead surface stop
Dead stop integral to the closer arm
NOTE A wall stop takes the lever at the height of the lever, which is where the force is, and needs a wall within the swing with backing behind it. A floor stop is the lowest-cost stop and the one a cane or a wheel catches, and it is set where the leaf's bottom rail meets it. An overhead stop moves the whole problem to the head of the opening where no wall is reachable, concealed in the leaf and frame or mounted on their surface. A dead stop in the closer arm uses the closer as the stop and loads the leaf's top rail with every slam. (13.4)
13.5 Wall stops and wall-mounted magnetic holders shall be fastened into the in-wall backing furnished under Gypsum Board AssembliesGypsum Board AssembliesResolves to the current adopted revision.sync/gypsum-board-assemblies, and where no backing exists behind the stop location, an overhead stop or a floor stop shall be furnished in its place.
13.6 Floor stops shall not be located within the maneuvering clearance of an accessible opening or in the path of travel across the opening.
13.7 Silencers shall be furnished at every hollow metal frame that receives no perimeter gasketing, three at the strike jamb of a single opening and two at the head of a pair.

14 Protection Plates and Push and Pull Trim

14.1 Protection plates and push and pull trim shall conform to ANSI/BHMA A156.6.
14.2 The protection plates furnished at the openings the hardware schedule assigns them to shall be as indicated in the datasheet.
Protection Plates Furnishedcheckbox
☑ Kick plate on the push face
☐ Mop plate on the pull face
☐ Armor plate on the push face
☐ Stretcher plate on both faces
☐ Edge guard on the lock stile
NOTE A kick plate takes the shoe and the cart at the bottom of the push face; a mop plate takes the mop on the pull face where the kick plate is not; an armor plate extends the kick plate to the height a cart, a bed, or a gurney strikes; a stretcher plate sits at the height of a stretcher rail; an edge guard wraps the lock stile where a cart catches the edge. The plates are scheduled where the traffic is, which is why they are a per-opening assignment and not a project-wide one. (14.3)

NOTE A stainless plate is the material through its thickness and matches the 630 finish family; brass and bronze match the warm finishes and show every scuff; aluminum is the lightest and least costly metal and dents; a plastic plate matches a laminate-faced leaf and is selected where a metal plate on a wood or laminate face is not wanted. A 10 in. kick plate covers the zone a shoe reaches, and an armor plate is sized to the height of whatever strikes the leaf, which is why its height has no norm. (14.7)
14.8 Plates shall be sized 2 in. less than the leaf width on the push face and 1 in. less than the leaf width on the pull face, and shall be attached with countersunk fasteners, or with an adhesive backing where the leaf's listing or construction does not admit screws.
14.9 Plates on a fire-rated leaf shall not extend higher above the bottom of the leaf than the leaf's listing permits, and a plate extending higher than 16 in. above the bottom of a rated leaf shall be a listed plate installed as the listing names.
14.10 Push and pull trim at openings that carry no latch shall be as indicated in the datasheet.
Push and Pull Trim Furnishedcheckbox
☑ Push plate

15 Pair Hardware: Coordinators, Flush Bolts, and Mullions

15.1 Coordinators and removable mullions shall conform to ANSI/BHMA A156.3, flush bolts and surface bolts to ANSI/BHMA A156.16, and every item at a fire-rated pair shall be covered by the assembly listing.
15.2 The latching arrangement at pairs carrying exit devices shall be as indicated in the datasheet, and the hardware schedule governs any pair it assigns a different arrangement.
Latching Arrangement at Pairs With Exit Devicesselect
Removable mullion with a rim device on each leaf
Vertical rod device on each leaf
Mortise device on the active leaf with a vertical rod device on the inactive leaf
Exit device on the active leaf with automatic flush bolts on the inactive leaf
NOTE A removable mullion gives each leaf a rim device latching into a fixed strike, which is the most reliable latch at a pair and keeps every rod and floor strike off the opening; the mullion divides the clear width when it is in and is keyed out for a wide load. Vertical rod devices on both leaves leave the full width clear at every opening, at the cost of two devices with rods to adjust. A mortise device on the active leaf with a rod device on the inactive leaf gives the active leaf a lockset-type latch and the inactive leaf an independent latch. An exit device on the active leaf with flush bolts on the inactive one is the lowest cost and leaves the inactive leaf without panic release, which is admissible only where the inactive leaf is not required for egress. (15.3)
15.4 The inactive leaf latching at pairs that carry no exit device shall be as indicated in the datasheet.
Inactive Leaf Latching at Pairs Without Exit Devicesselect
Automatic flush bolts
Constant-latching flush bolts
Manual flush bolts
Surface bolts
NOTE Automatic flush bolts retract when the active leaf is opened and project when it closes, so the inactive leaf latches without anyone remembering to throw a bolt. Constant-latching bolts project whenever the inactive leaf is closed and release by a trigger when the active leaf opens. Manual flush bolts are thrown by hand and are what a fire door inspector finds unthrown. Surface bolts are mounted on the face and are selected where the leaf edge cannot be mortised. (15.5)
15.6 At a fire-rated pair without a mullion, the inactive leaf shall be latched by automatic or constant-latching flush bolts, and manual flush bolts shall be furnished only where the inactive leaf is not required for egress, NFPA 80 permits them at that pair, and the authority having jurisdiction accepts them.
15.7 A coordinator shall be furnished at every pair that carries an overlapping astragal or a meeting-edge seal that requires the inactive leaf to close first and at every pair with automatic flush bolts, together with the filler bar and the mounting brackets its length requires.
NOTE The astragal at a pair is furnished with the leaves under the door standard that supplies them, and this standard furnishes the coordinator, the bolts, the mullion, and the meeting-stile seal that work with it. (15.8)
15.9 Removable mullions at fire-rated pairs shall be listed for the rating period and shall be keyed removable only where the listing provides for it, and a mullion at a pair carrying fire exit hardware shall be reinstalled and secured after every removal.
15.10 Where an electrified mullion carries power to a device on the leaf, the mullion shall be furnished with its power transfer as part of the hardware set.

16 Thresholds, Gasketing, and Door Bottoms

16.1 Thresholds shall conform to ANSI/BHMA A156.21, and gasketing, door bottoms, and edge seal systems shall conform to ANSI/BHMA A156.22.

Threshold Type at Exterior Openingsselect
No threshold
Saddle threshold
Bumper-seal threshold
Interlocking threshold with a hook door bottom
Thermal-break threshold

NOTE A saddle is a flat bar that closes the gap and takes a sweep on the leaf; a bumper-seal threshold carries a vinyl insert the leaf closes against; an interlocking threshold hooks a shaped door bottom and is the tightest against driven rain and the one a wheel feels most; a thermal-break threshold divides the inside and outside halves with a plastic bridge where the sill would otherwise condense; an offset threshold steps up to an interior floor that is higher than the exterior slab. The condition at the sill, the exposure, and the accessible route together select the threshold at each exterior opening. (16.3)

(16.5)
16.6 Thresholds at interior openings shall be furnished where the hardware schedule assigns one, at a change of floor finish, at a sound-rated opening, and at a smoke or fire-rated opening whose listing requires one.

(16.11)
16.12 The door bottom at sound-rated openings, and at smoke and draft control assemblies whose listing requires one, shall be as indicated in the datasheet.
Door Bottom at Sound-Rated and Smoke-Rated Openingsselect
Surface-mounted automatic door bottom
Semi-mortised automatic door bottom
Mortised automatic door bottom
NOTE An automatic door bottom retracts into its housing while the leaf is moving and drops onto the threshold or the floor in the last part of the closing arc, which is what lets it clear a carpet inside and still seal. A surface-mounted unit is screwed to the face and is visible; a semi-mortised unit sits in a shallow groove with its face plate flush; a mortised unit is hidden in the bottom rail and needs a leaf built with the mortise and a bottom rail deep enough to take it. (16.13)
16.14 Gasketing at a fire-rated opening and at a smoke and draft control assembly shall be a product listed for that use, installed as the listing and NFPA 80 or NFPA 105 require, and shall not be substituted by an unlisted gasket in the same profile.
16.15 Where the positive-pressure edge seal category selected under the door standard places the intumescent seal in the hardware sets, the Contractor shall record on the hardware schedule which openings receive the seal under this standard, so that each opening receives exactly one seal.
16.16 The acoustic seal set furnished under this standard at a sound-rated opening shall be the seals and the threshold described in the leaf manufacturer's test report for the scheduled rating.
NOTE A sound-rated opening reaches the rating of its tested assembly only with the seal set that was in the test, and the automatic door bottom is the item most often left off. The absence is found at acoustic commissioning, after the leaf is hung and the floor is down. (16.17)
16.18 Gasketing at exterior openings shall be installed continuously around the head and both jambs without interruption at the hinge and strike preparations, and the Contractor shall verify after the closer is adjusted that gasketing compression does not prevent the leaf from latching.

BHMA 630, satin stainless steel
BHMA 690, dark bronze painted
NOTE A plated finish is a coating over a different base metal, and once it wears through at a lever's contact point the base is exposed and the mark is permanent. A solid stainless finish is the base metal itself, so wear polishes it rather than breaching it, which is the mechanism behind its use where hands touch hardware all day and where salt air or washdown reaches it. The brass and bronze families are living finishes unless clear coated, and the clear coat is what keeps them even across a building. The painted finishes, 689 and 690, are how a closer or a holder with a cast aluminum body is brought to the color of the plated hardware beside it. (17.4)
17.5 All hardware within one set shall carry the same finish code, and closers, holders, and other items available only in a painted finish shall be furnished in the painted finish that matches the set.
17.6 Where a required item is not manufactured in the selected finish code, the supplier shall submit the closest available finish for review before the item ships.
17.7 Finish shall be matched across manufacturers on the actual items, and the accepted sample shall be the standard for every item of that finish code on the project.

18.1 Patch fittings, rails, pivots, locks, and closers for all-glass swing doors hung in interior glass partitions shall be furnished under this standard, rated by their manufacturer for the leaf size, the leaf weight, and the glass thickness indicated below.
18.2 The glass thickness the all-glass door fittings are rated for shall be as indicated in the datasheet.
Glass Thickness Rated for All-Glass Door Fittingsrange
in
0.3750.50.75
NOTE Patch fittings and rails are machined for one glass thickness and clamp on it; a 3/8 in. leaf in a 1/2 in. fitting rocks in the clamp and a 1/2 in. leaf does not enter a 3/8 in. fitting. The 1/2 in. leaf is the common interior door, 3/8 in. serves a small and light leaf, and 3/4 in. serves a tall or wide one. The tempered or laminated panel itself, its thickness, and its edge work are governed by Interior GlazingInterior Glazing and Glass PartitionsResolves to the current adopted revision.sync/interior-glazing, which glazes the leaf to the thickness selected here. (18.3)
18.4 The fitting type at all-glass swing doors shall be as indicated in the datasheet.
All-Glass Door Fitting Typeselect
Patch fittings at the top and bottom corners
Full-width top and bottom rails
Patch fitting at the top with a bottom rail
NOTE A corner patch is the smallest piece of metal on the leaf and carries the pivot and the lock in the corners; a full-width rail carries the pivot, the lock, and a door bottom seal along the whole edge, takes a heavier leaf, and reads as a framed bottom; a top patch over a bottom rail puts the seal and the lock at the floor and keeps the head clean. (18.5)
18.6 The closing device at all-glass swing doors shall be as indicated in the datasheet.
All-Glass Door Closing Deviceselect
Floor closer with a bottom pivot in the floor
Overhead concealed closer in the partition header
Surface closer mounted to a top rail
Free-swinging pivots without a closer
NOTE A floor closer holds the closer under the floor finish and needs a recess in the slab and a cement case set before the floor goes down; an overhead concealed closer sits in the partition header and needs a header deep enough to take it; a surface closer on a top rail is the one closer that goes on after the fact; free-swinging pivots leave the leaf where it is pushed and are selected where the partition carries no acoustic or privacy function. (18.7)
18.8 Locks at all-glass swing doors shall be as indicated in the datasheet.
All-Glass Door Lockselect
No lock
Patch lock at the lock stile with a strike on the adjacent panel or jamb
Bottom rail deadbolt into a floor strike
Electromagnetic lock in the header with a leaf armature
NOTE A patch lock latches into the adjacent panel or a wall jamb at lever height and is the lock a person expects to find; a bottom rail bolt drops into a floor strike and leaves the stile clean but is thrown by bending down; a header magnet needs no cutout in the leaf and is an electrified lock under the Electrified Hardware section of this standard, with all of that section's egress obligations. (18.9)
18.10 All-glass swing doors in a means of egress shall carry the same egress release, operating force, and operable-part obligations as every other door under this standard.
18.11 Floor closers at all-glass doors shall be set in a cement case anchored to the slab before the floor finish is placed, with the pivot location confirmed against the partition shop drawings.
NOTE A frameless all-glass entrance bought as a system, with its glass panels, patch fittings, rails, pivots, and closers engineered together, is governed by All Glass EntrancesAll-Glass Entrances and DoorsResolves to the current adopted revision.sync/all-glass-entrances. The hardware furnished with aluminum entrance doors is governed by Aluminum Entrances And StorefrontsAluminum Entrances and StorefrontsResolves to the current adopted revision.sync/aluminum-entrances-and-storefronts. (18.12)

19 Electrified Hardware

19.1 Electrified Items and Coordination

19.1.1 Electrified locking devices shall conform to ANSI/BHMA A156.25, electromagnetic locks to ANSI/BHMA A156.23, electric strikes to ANSI/BHMA A156.31, and delayed egress locking systems to ANSI/BHMA A156.24, and electrified locking hardware shall additionally be listed under UL 1034 where the opening is required to resist burglary.
19.1.2 The electrified hardware items furnished on the project shall be as indicated in the datasheet, assigned opening by opening on the hardware schedule.
Electrified Hardware Items Furnishedcheckbox
☐ Electric strike
☐ Electromagnetic lock
☐ Electrified mortise lockset
☐ Electrified bored lockset
☐ Electrified exit device trim
☐ Electric latch retraction exit device
☐ Delayed egress locking device
☐ Electromagnetic hold-open device
☐ Electrified removable mullion
☐ Key switch
☐ Credential reader integral to the lock trim
NOTE The electrified locking device at an opening is the mechanism that secures it, and the families differ in what they do when nothing is powered. An electrified lockset or an electrified exit device trim keeps a mechanical latch and a free-turning egress lever, so the egress side always works and only the access side is controlled. An electric strike leaves the lock mechanical and releases the keeper in the frame. An electromagnetic lock has no latch at all and holds the leaf by magnetic force, so every egress release is an electrical event, and it is the device that attracts the most code conditions. A delayed egress device holds an egress door for the interval the code allows after the device is pushed and is permitted only in the occupancies the code names. (19.1.3)
19.1.4 The hardware supplier shall issue, for every electrified opening, the point-to-point wiring diagram listed under Action Submittals, and the hardware supplier and the access control installer shall jointly confirm every electrified opening against it before the frames are fabricated.
NOTE The raceway in a wood leaf is furnished under Wood DoorsWood DoorsResolves to the current adopted revision.sync/wood-doors, the conduit, junction boxes, and through-bolt reinforcement in hollow metal are furnished under Exterior Doors And FramesHollow Metal Doors and FramesResolves to the current adopted revision.sync/exterior-doors-and-frames, and the controllers, power supplies, and cabling beyond the opening are furnished under Access Control SystemsAccess Control SystemsResolves to the current adopted revision.sync/access-control-systems; this standard furnishes the devices, the power transfer, and the connections at the opening. (19.1.5)

19.2 Fail Mode at Electrically Locked Openings

19.2.1 The fail mode at each electrically locked opening shall be as indicated in the datasheet.
Fail Mode at Electrically Locked Openingsselect
Fail safe, unlocked on loss of power
Fail secure, locked on loss of power
Per drawings — the hardware schedule (deferred by default)
19.2.2 A door in a means of egress that is electrically locked shall unlock on loss of power to the locking device, unless the installation satisfies in full a provision of Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code that expressly permits the arrangement without that release.
19.2.3 Every electromagnetic lock on a door in a means of egress shall release on activation of the fire alarm system, on activation of the automatic sprinkler system where the permitting provision requires it, on loss of power, and on operation of the request-to-exit device and the manual release the permitting provision requires at that opening.
19.2.4 A sensor-released or electromagnetically locked egress door shall be furnished with the manual release, the signage, and the door-mounted release hardware the provision that permits it requires, and the arrangement shall be accepted by the authority having jurisdiction before the device is ordered.
19.2.5 A delayed egress device shall release not more than 15 seconds after it is actuated, or 30 seconds where the authority having jurisdiction has approved the longer delay, and shall release immediately on fire alarm activation, on sprinkler activation, and on loss of power.
NOTE The fail mode carries opposite consequences at the two ends of the opening. A fail-secure device that loses power holds people on the wrong side of it; a fail-safe device that loses power opens a secured space to anyone in the building. Which risk a project accepts is a decision for the Owner with the Architect, and it belongs on the hardware schedule so it is recorded per opening rather than assumed. (19.2.6)

19.3 Power Transfer to the Leaf

19.3.1 The method of transferring power into the leaf at openings with a leaf-mounted electrified item shall be as indicated in the datasheet.
Power Transfer Methodselect
Electric through-wire hinge
Continuous hinge with integral wiring
Concealed electric power transfer in the hinge edge
Concealed armored door loop
Surface-mounted armored door cord
NOTE A through-wire hinge carries a few conductors in a hinge that looks like every other hinge and is the lowest-cost transfer; its wires are the finest on the opening and the first thing to fail if the hinge is ever pulled. A wired continuous hinge carries more conductors along a hinge that already serves the high-cycle opening. A concealed electric power transfer mortises into the hinge edge of the leaf and the frame and carries the conductor count a latch-retraction device needs, at a mortise in both. A concealed loop is a flexible conduit between leaf and frame hidden in the hinge edge, and a surface cord is the same loop on the face and the one transfer that goes on an existing leaf without machining. (19.3.2)
19.3.3 Conductors crossing from the frame into the leaf shall be carried in a device made for that purpose and shall not be looped unprotected across the hinge line.
19.3.4 The transfer device shall be included in the hardware set for every opening carrying a leaf-mounted electrified item, and its conductor count and gauge shall match the device it feeds.
NOTE An unprotected conductor at the hinge line flexes through its full bend radius every time the door swings, which at a busy opening is hundreds of cycles a day. Its failure is intermittent long before it is total, which is why it is usually diagnosed as a controller fault first. (19.3.5)

19.4 Operating Voltage

19.4.1 Electrified hardware shall operate at the voltage indicated in the datasheet, and every device on the project shall be furnished for that voltage unless the hardware schedule states a different voltage at a named opening.
Electrified Hardware Operating Voltageradio
● 24 VDC
○ 12 VDC
NOTE At the same power, a 24 VDC device draws half the current of a 12 VDC device, so the voltage drop on a given conductor run is half as large and the run to a remote opening can be twice as long before the device falls below its rated voltage. Devices that exist only at 12 VDC are the exception the schedule names. (19.4.2)
19.4.3 Each device shall be furnished with its rated voltage and its inrush and holding current stated on the wiring diagram, so that the power supply and the conductors furnished under Access Control SystemsAccess Control SystemsResolves to the current adopted revision.sync/access-control-systems can be sized to hold the voltage at the device within the manufacturer's stated range under its rated load.
NOTE An electromagnetic lock that receives less than its rated voltage still energizes and still appears locked. It simply does not develop its rated holding force, and the deficiency is invisible until someone pulls hard enough to find it. (19.4.4)
19.4.5 Electrified hardware shall be supplied from Class 2 circuits fed by power supplies listed under UL 294, and no electrified hardware item shall be connected to line voltage at the opening.

19.5 Fire Alarm Release

19.5.1 Every electromagnetic hold-open device on a fire door assembly or a smoke and draft control assembly, every electromagnetic lock on a door in a means of egress, and every fire exit hardware device with electric latch retraction shall be connected to the building fire alarm system so that alarm activation releases the hold-open, releases the lock, and projects the latch.
19.5.2 The release circuit shall be arranged so that loss of power to the circuit also releases every device on it, and activation of the fire alarm system shall release every hold-open device within the affected zone simultaneously.
19.5.3 The Contractor shall coordinate the relay contacts, the release circuit conductors, and the device quantities with the fire alarm installer working under Fire Alarm SystemsFire Alarm SystemsResolves to the current adopted revision.sync/fire-alarm-systems, and the release point shall be recorded at the pre-installation conference.
19.5.4 Holding a fire door open with a wedge, a chair, a stop, or any device not released by the fire alarm system is prohibited by NFPA 80, and the Contractor shall neither do so during construction nor leave such a condition at turnover.

20 Accessible Opening Requirements

20.1 Openings on an accessible route shall comply with the accessibility standard adopted by the authority having jurisdiction, and where that standard and ICC A117.1 differ, the adopted standard shall govern.
20.2 The Architect shall identify the accessible route on the drawings, and the hardware schedule preparer shall confirm that every opening on that route complies with the requirements of this section.
20.3 Operable parts of door hardware on an accessible route, including levers, pulls, exit device actuating members, key cylinders operated by the public, push-to-exit controls, and power operator actuators, shall be mounted not less than 34 in. and not more than 48 in. above the finished floor.
20.4 Operable hardware on an accessible route shall be operable with one hand and shall not require tight grasping, tight pinching, or twisting of the wrist to operate.
20.5 The force required to operate operable hardware on an accessible route shall not exceed 5 lbf.
20.6 The force required to push or pull open an interior swinging door on an accessible route, other than a fire door assembly, shall not exceed 5 lbf applied at the latch edge, and an exterior door or a fire door assembly shall release its latch at not more than 15 lbf, be set in motion at not more than 30 lbf, and swing to the full open position at not more than 15 lbf.
20.7 Closers on an accessible route shall be adjusted so that, from an open position of 90 degrees, the leaf takes not less than 5 seconds to move to a position 12 degrees from the latch, and spring hinges shall be adjusted so that the leaf takes not less than 1.5 seconds to move from 70 degrees open to the closed position.
20.8 A threshold in an accessible route shall present a change in level of not more than 1/2 in., and any portion of that change exceeding 1/4 in. shall be beveled at a slope not steeper than 1:2.
20.9 The push face of a swinging door on an accessible route shall be smooth within 10 in. of the finished floor across the full width of the leaf, with any plate or joint in that zone within 1/16 in. of the plane of the face, except where the adopted standard exempts an all-glass leaf with a tapered bottom rail or shoe.
20.10 Where a fire door assembly requires a closing force that cannot be reconciled with the opening force limit, the Contractor shall raise the conflict in writing with the Architect and the authority having jurisdiction rather than adjusting the closer below the force needed to latch the leaf.
20.11 Maneuvering clearances required by the adopted accessibility standard shall be kept clear of floor stops, wall stops, holders, and pulls, and the Architect shall confirm the clearances shown at each accessible opening before frames are set.
NOTE The opening force limit and the hardware operating force limit are separate obligations that apply at the same time. A lever that meets the operable-force limit on a door whose closer is set above the opening-force limit leaves the opening non-compliant, and the reverse is equally true. Accessibility obligations are not selections; they apply wherever the route applies, and no datasheet entry in this standard relaxes them. (20.12)

21 Installation

21.1 Hardware shall be installed at the locations established by the approved hardware templates, at the locations of ANSI/NAAMM HMMA 831 in hollow metal and DHI WDHS.3 in wood leaves unless the hardware schedule locates an item otherwise, and in accordance with the manufacturer's published instructions.
21.2 Hardware shall be installed only after the leaves and frames are finished, except for the hinges and the items needed to hang the leaf for fitting, and finished hardware shall be protected from paint, plaster, and sealant through the remainder of the work.
21.3 Hardware at fire door assemblies shall be installed in accordance with NFPA 80, with no field modification of a labeled leaf or frame beyond the job-site preparations NFPA 80 permits, and no fastener hole shall be made in a labeled leaf or frame for an item the listing does not cover.
21.4 Fire door assemblies shall be installed to the clearances the listing and NFPA 80 require, and the Contractor shall report in writing any frame that is out of tolerance before hanging a leaf in it.
21.5 Closers shall be adjusted after the leaf and frame are fully installed, the gasketing is in place, and the building is under its normal pressure conditions, for sweep speed, latch speed, backcheck, and spring power, and the adjustment shall be recorded at every accessible opening.
21.6 Electrified hardware shall be installed, terminated, and functionally tested by the manufacturer-trained installer, with every conductor labeled at both ends and the wiring diagram marked up to the as-installed condition.
21.7 Thresholds shall be set in a full bed of sealant, anchored at the spacing the manufacturer publishes with fasteners of stainless steel or of the threshold material, and notched around the frame stops so that no gap remains at the jamb.
21.8 The Contractor shall coordinate the latch-side wall space at each opening with the tactile signage installed under Signage And Egress MarkingsCode-Required Signage and Egress MarkingsResolves to the current adopted revision.sync/signage-and-egress-markings, so that no stop, holder, or leaf in its open position obstructs the sign.
21.9 The Contractor shall instruct the Owner's maintenance personnel in the adjustment of closers, the operation of the keying system and the interchangeable cores, and the function of every electrified opening before final acceptance, and shall record the instruction.
21.10 Every installed item shall operate freely without binding, with the latch engaging the strike without forcing and the leaf closing and latching under its closer alone.

22 Field Quality Control

22.1 Every opening shall be operated through a full cycle after installation and adjustment, and any item that binds, fails to latch, or fails to hold its adjustment shall be corrected before the opening is presented for inspection.
22.2 At every accessible opening, the opening force and the closing time shall be measured with a door pressure gauge and a timer, recorded by opening mark, and corrected to the limits of the Accessible Opening Requirements section where they are exceeded.
22.3 Every fire door assembly shall receive the acceptance test NFPA 80 requires after installation, performed by a person with the qualifications NFPA 80 names, and the Contractor shall correct any leaf that does not close and latch under its closer alone, any clearance outside the listing, and any missing or defaced label before the inspection is recorded.
22.4 Every electrified opening shall be tested with the access control system and the fire alarm system in service to demonstrate the specified fail mode, the release on fire alarm, the release on loss of power, and the egress release, and the test shall be witnessed by the Architect or the Owner's representative and recorded.
22.5 Every power-operated opening shall be tested after installation to the opening and closing times, the stall force, and the manual operation with power off that ANSI/BHMA A156.19 requires, with the measured values recorded by opening mark.
22.6 The cost of retesting an opening that fails a field test, and of the trades attending the retest, shall be borne by the Contractor.
NOTE Fire door assemblies are inspected and tested annually after acceptance under NFPA 80, and the acceptance record delivered at closeout is the baseline the Owner's inspector compares against. (22.7)

23 Delivery, Storage, and Handling

23.1 Hardware shall be delivered in the manufacturer's packaging, each package marked with the opening mark and the hardware set it serves, with the templates and the fasteners packed with the item they serve.
23.2 Hardware shall be stored off the floor in a dry, locked room, and cylinders, cores, keys, and electrified devices shall be stored in a locked cabinet within that room under the control of one named person.
23.3 Keys and cores shall not be issued to any trade except against a signed record, and the record shall be reconciled before the permanent cylinders are installed.
NOTE Finish hardware is the most portable material on a site and the one whose replacement never quite matches the rest of the set, which is why it is stored locked and issued against a record. (23.4)

24 Warranty

24.1 Each hardware manufacturer shall warrant its products against defects in materials and workmanship for not less than the period indicated in the datasheet.
Minimum Hardware Warranty Periodrange
yr
123510
24.2 Door closers shall be warranted against defects in materials and workmanship, including loss of closing power and fluid leakage, for not less than the period indicated in the datasheet.
Minimum Door Closer Warranty Periodrange
yr
125102530
NOTE Closers are the item that fails in service, by a seal letting the fluid out or a spring losing its power, and the major manufacturers publish closer warranties of ten years and longer, so a closer floor set well above the general floor costs the project nothing. Exit devices and locksets commonly carry published terms of three to five years, and the general floor is set so that the shortest published term on the project is still a term the Owner accepted; a floor set above the published terms narrows the bidders to the manufacturers who publish it. (24.3)
24.4 Where a manufacturer publishes a longer warranty for a product category than the period indicated, that longer warranty shall apply in addition to the period indicated and shall not be waived by it.
24.5 A warranted repair or replacement shall carry a fresh warranty of the original period running from the date of the repair, or the unexpired remainder of the original period, whichever ends later.
24.6 The Contractor shall bear the cost of removing and reinstalling adjacent work that must be disturbed to make a warranty repair, and the cost of repairing collateral damage caused by the repair.
24.7 The Contractor shall warrant the installation, including the operation of every hardware item and the compliance of every fire door assembly with the clearance and closing requirements of NFPA 80, for the period established in the general conditions of the Contract, and shall correct deficiencies attributable to installation workmanship at no cost to the Owner.
24.8 The hardware supplier shall furnish at closeout a consolidated summary listing, for every product on the project, the warranty period and the service contact.
