− When to use: Specifying, furnishing, and installing finish hardware for swinging door openings in commercial, institutional, and light-industrial construction. Covers hardware sets as the organizing framework; hinges and pivots; cylindrical, mortise, and bored locksets; rim, mortise, and vertical-rod exit devices including fire exit hardware; door closers and hold-opens; stops, holders, and protection plates; thresholds, weatherstripping, and gasketing; coordinators and flushbolts for pairs; finish selection; keying hierarchy and master-key schedules; electrified hardware items (electric strikes, electrified locks, electromagnetic hold-opens, power transfers) at the hardware-set level; ADA / ICC A117.1 height, force, and handle compliance; DHI location templates; and field verification. Use it where the door leaf and frame are specified elsewhere.
− Not intended for: Door leaves and hollow metal frames (see [[sync/doors-frames-and-hardware]], [[sync/exterior-doors-and-frames]], [[sync/wood-doors]]); access control head-end, card readers, controllers, and power supplies (see [[sync/access-control-systems]]); automatic pedestrian door operators; aluminum storefront entrance hardware (see [[sync/aluminum-entrances-and-storefronts]]); interior frameless glass pivots and patch fittings (see [[sync/interior-glazing]]); overhead coiling and sectional door hardware (see [[sync/overhead-coiling-doors]], [[sync/sectional-overhead-doors]]); and detention or ballistic-rated security hardware.
+ When to use: Finish hardware for swinging door openings specified and furnished as its own package, separate from the door leaves and the frames, in commercial, institutional, educational, healthcare, hospitality, and multi-family residential work. Covers the hardware schedule and numbered hardware sets as the coordination instrument; ANSI/BHMA operational grades; butt hinges, continuous hinges, pivots, and self-closing hinges; bored, mortise, interconnected, and tubular locksets and latches, auxiliary locks, and trim; cylinders, interchangeable cores, keyway control, keying hierarchy, construction keying, and key control; panic hardware and fire exit hardware; door closers, overhead stops and holders, and fire-alarm-released hold-open devices; door stops, silencers, protection plates, and push and pull trim; coordinators, flush bolts, and removable mullions at pairs; thresholds, weatherstripping, smoke and acoustic gasketing, intumescent edge seals furnished under the hardware sets, and automatic door bottoms; patch fittings, rails, pivots, locks, and closers for all-glass swing doors in interior partitions; electrified locks, strikes, exit devices, electromagnetic locks, delayed egress devices, and the power transfer into the leaf; low-energy power-operated and power-assist swing door operators under ANSI/BHMA A156.19 with their knowing-act actuators; hardware finishes; accessible-opening obligations; installation, adjustment, field verification, fire door acceptance inspection, warranty, and spare parts.

# Scope {toc}
−## This standard governs the selection, furnishing, and installation of finish hardware for swinging door openings, organized as numbered hardware sets, across commercial, institutional, and light-industrial occupancies. {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. {note}
−## The opening is a coordinated assembly whose parts are specified by three complementary standards, and this is the hardware-only complement. The door leaf, the frame, gauges, cores, and fire-label assembly requirements are governed by [[sync/doors-frames-and-hardware]] for combined opening packages, by [[sync/exterior-doors-and-frames]] for exterior leaves, and by [[sync/wood-doors]] for wood leaves. This standard is used when the hardware is specified separately from the door and frame manufacturing, which is common on larger projects where a hardware consultant authors the sets. {note}
+## 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.
−## Hardware sets shall be the organizing framework, with one numbered set assigned to each distinct opening type and every opening on the door schedule referencing exactly one set.
+## The leaves and the frames are separate subjects. Hollow metal doors and frames, with their factory reinforcement for this hardware, are governed by [[sync/exterior-doors-and-frames]]. Wood leaves, with their machining, blocking, and raceway, are governed by [[sync/wood-doors]]. Where the door, the frame, and the hardware are bought together as one coordinated supply, [[sync/doors-frames-and-hardware]] applies in place of this standard. {note}
−## Where a single opening is described by both this standard and a door or frame standard, the more specific requirement for that component shall govern, and conflicts shall be resolved by the Architect in writing.
+## 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 [[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 [[sync/fire-alarm-systems]]. {note}
−## Electrified hardware items shall be specified in this standard at the product and hardware-set level only; their power supplies, conduit, raceway, and system programming are governed by [[sync/access-control-systems]] and shall be coordinated with that work and with [[sync/fire-alarm-systems]].
+## 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 [[sync/interior-glazing]]. Frameless all-glass entrance assemblies furnished as a system, the glass panels together with their fittings and closers, are governed by [[sync/all-glass-entrances]]. {note}
−## Related standards {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 [[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. {note}
−### The following standards carry adjacent scope and are commonly coordinated with this work: {note}
−- [[sync/doors-frames-and-hardware]] — combined opening packages where leaf, frame, and hardware are specified together.
−- [[sync/exterior-doors-and-frames]] and [[sync/wood-doors]] — door leaf manufacturing this standard relies on for prep and reinforcement.
−- [[sync/access-control-systems]] — head-end equipment and low-voltage power for electrified hardware specified here.
−- [[sync/aluminum-entrances-and-storefronts]] and [[sync/interior-glazing]] — glazing-integral hardware excluded here.
−- [[sync/fire-alarm-systems]] — release signal for electromagnetic hold-opens.
−- [[sync/gypsum-board-assemblies]] — wall backing and blocking for wall-mounted stops and magnetic holders.
−- [[sync/overhead-coiling-doors]] and [[sync/sectional-overhead-doors]] — non-swinging doors with their own hardware.
+## 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.
+## 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. {note}
+
+## 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.
+
# Referenced Standards {toc}
−## Hardware, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited or a more recent edition is mandated by the authority having jurisdiction.
+## Hardware, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited.
## Where referenced standards conflict, the more stringent requirement shall govern unless the Architect directs otherwise in writing.
+## Hardware at fire-rated openings shall comply with the edition of the fire test standard under which the door assembly is listed, and [[parameter: adopted-building-code]] governs which opening protective rating and which egress provisions apply at each opening.

# Quality Assurance {toc}
−## On projects with 50 or more openings, significant electrified hardware, or complex keying hierarchies, a Certified Architectural Hardware Consultant (AHC or DAHC) adds value that far exceeds their fee: omitting the consultant shifts the entire coordination burden onto the General Contractor during submittals, reliably multiplies RFIs, and the cost of late frame rework and re-keying is many times the consultant's cost. {note}
+## Authorship of the Hardware Schedule {toc}
−## On projects of 50 or more openings, the hardware sets and schedule shall be prepared or reviewed by a Certified Architectural Hardware Consultant.
+### The hardware schedule and the hardware sets shall be prepared by the party indicated in the datasheet.
−## The Contractor shall reconcile the hardware schedule against the door and frame schedule before any hardware is procured.
+```datasheet
+label: Hardware Schedule Preparer
+type: select
+options:
+ - "Architectural Hardware Consultant holding a current DHI certification"
+ - "Hardware supplier's consultant with a record of comparable projects"
+ - "The Architect's hardware specifier"
+```
−### Frame prep for hinges, strikes, closers, and exit devices is punched in the shop when the frame is fabricated. A hardware change discovered after the frame is built requires field welding, a new frame, or a non-conforming workaround, so reconciliation must precede procurement. {note}
+### 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.
−## The hardware installer for electrified items shall be trained and certified by the hardware manufacturer for the products installed.
+### 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.
−## A pre-installation conference shall be held with the hardware supplier, installer, electrical contractor, and access control and fire alarm trades before frames are set.
+### 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. {note}
−### Electric strikes, electrified locks, electrified exit devices, and electromagnetic hold-opens all require conduit, power supplies, and a fire-alarm interface that must be in the wall before the frame is set. Coordinating this after the rough-in is closed is a common and expensive miss. {note}
+## Supplier and Installer Qualifications {toc}
−# Hardware Sets and Grading {toc}
+### 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.
−## Hardware sets are the contract organizing unit, and the grade selected for each category sets the service life of the opening. {note}
+### 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.
−### Each numbered hardware set lists every item a given opening type requires, from hinges through the threshold, so that the schedule resolves an opening to a complete, procurable list. Grade 1 is the heavy commercial and institutional class under the ANSI/BHMA A156 series; Grade 2 is light commercial and residential; Grade 3 is residential. {note}
+### 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.
−## Each opening shall be assigned exactly one numbered hardware set, and the set shall list every hardware item the opening requires.
+## Pre-Installation Conference {toc}
−## All hardware shall be Grade 1 per the applicable ANSI/BHMA A156 standard for commercial and institutional work, including IBC occupancy groups A, B, E, I, M, and R-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.
+### 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.
+
+### 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. {note}
+
+# Hardware Sets and the Hardware Schedule {toc}
+
+## 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.
+
+## The hardware set assigned to each opening shall be [[drawing: as stated on the door schedule]].
+
+## 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.
+
+## The hardware schedule format shall be as indicated in the datasheet.
+
```datasheet
−label: Default hardware grade
+label: Hardware Schedule Format
type: radio
options:
− - Grade 1 (heavy commercial / institutional)
− - Grade 2 (light commercial / residential common areas)
−default: Grade 1 (heavy commercial / institutional)
+ - "Vertical format, listing each set once with the openings it serves"
+ - "Horizontal format, listing each opening with its items across one line"
+default: "Vertical format, listing each set once with the openings it serves"
```
−## Grade 2 hardware may be used only in light commercial single-tenant office space or residential common areas, and any such downgrade shall be documented in the hardware schedule.
+## 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. {note}
−### Specifying Grade 2 locksets or closers to save cost in assembly, educational, or healthcare occupancies produces premature failure under high cycle counts. The savings are recovered as warranty calls and early replacement within the first few years. {note}
+## 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.
−### The party responsible for preparing the hardware sets, a Certified Architectural Hardware Consultant or the architect, shall be specified and documented in the hardware schedule.
+## 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.
+## 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.
+
+## 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.
+
+## 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. {note}
+
+# Operational Grades {toc}
+
+## 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. {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. {note}

−### A cylindrical (bored) lockset fits a bored door prep and is the workhorse of commercial interiors; a mortise lockset uses a rectangular case let into the door edge and offers heavier duty, more functions, and integral deadbolt options at higher cost. Function names — passage, privacy, classroom, storeroom, office, dormitory, communicating, entrance — describe exactly which side latches, locks, or unlocks, and are selected per room, not per door type. {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. {note}
−## All locksets shall be Grade 1 per ANSI/BHMA A156.2 for bored locksets and per ANSI/BHMA A156.13 for mortise locksets.
+## 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.
−## Lever or loop trim shall be provided on all locksets and latchsets; knobs shall not be used.
+## 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.
−### ICC A117.1 requires operable hardware that does not require tight grasping, pinching, or wrist twisting. A lever or loop handle satisfies this; a round knob does not and is non-compliant on accessible openings. {note}
+## 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.
−## The lock function for each opening shall match the room use designated on the schedule, and a function not on the standard list shall not be substituted without the Architect's approval.

−## Mortise locksets shall be used where the schedule designates heavy-duty service, integral deadbolt, or a function not available in a cylindrical case.
+## 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. {note}

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. {note}

−# Exit Devices {toc}
+## 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. {note}
−## Exit devices provide single-operation egress under load, and the distinction between panic hardware and fire exit hardware is a life-safety boundary that drives both listing and dogging. {note}
+## A knob shall not be furnished at an opening on an accessible route regardless of the datasheet selection.
−### Panic hardware is listed to UL 305 for egress-only openings and may be mechanically dogged to hold the latch retracted. Fire exit hardware is listed to both UL 305 and UL 10C and is required on fire-rated openings, where it must positively latch on every cycle. Specifying panic hardware on a fire-rated opening, or leaving mechanical dogging enabled on a fire door, is a code defect that fails inspection. {note}

−## Fire exit hardware listed to both UL 305 and UL 10C shall be provided on all fire-rated egress openings.
+## 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. {note}
−## Mechanical dogging shall not be provided on fire-rated openings; cylinder dogging or electric latch retraction shall be used where the schedule requires the latch held retracted on a fire door.
+## 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 [[parameter: 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.
−## The exit device type shall match the door and frame prep, and the device type shall not be changed against an already-fabricated frame without re-prepping or replacing the frame.
+## 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.
−### Rim devices need a frame-mounted rim strike; mortise devices need a mortise prep; surface and concealed vertical-rod devices need top and bottom preps. Substituting one type for another after the frame is built is a major RFI and often a frame replacement. {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. {note}
−## Exit device operating force shall not exceed 15 lbf to release the latch, per NFPA 101 and IBC Section 1010.

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.

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. {note}

−# Stops, Holders, and Protection Plates {toc}
+## 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. {note}

+## The arm configuration at each opening shall be [[drawing: as stated on the hardware schedule]] to suit the mounting face and the stop condition of that opening, rather than selected project-wide.

−## Wall stops shall be installed only where solid blocking or backing exists in the wall, coordinated with [[sync/gypsum-board-assemblies]]; a floor stop or overhead stop shall be used where backing is absent.
+## 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. {note}

−# Thresholds, Weatherstripping, and Gasketing {toc}
+## 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. {note}
−## The threshold and seal package controls air, water, smoke, and sound at the opening perimeter, and ADA limits the threshold profile a wheelchair must cross. {note}
+## 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.
−### A threshold seals and transitions the floor at the opening; weatherstripping at the head and jambs and a sweep or automatic door bottom at the base complete the seal. Smoke seals are required on smoke-rated assemblies, acoustic seals on sound-rated assemblies, and weather seals on exterior openings. A sound-rated door needs both perimeter gasketing and an automatic door bottom to reach its rated STC. {note}
+## 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.

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.

−### A fail-safe device unlocks when power is removed and is required on egress doors and on fire-alarm-released hold-opens, so people are never trapped on a power loss. A fail-secure device locks when power is removed and is appropriate for protecting a secure room. Choosing the wrong mode is a life-safety defect on egress and a security defect on a secured opening. {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. {note}

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.

+
+### 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.
+
+### 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.

+
+## Power Transfer to the Leaf {toc}
+
+### The method of transferring power into the leaf at openings with a leaf-mounted electrified item shall be as indicated in the datasheet.
+

+type: select
+options:
+ - "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"
+```
+
+### 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. {note}
+
+### 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.
+
+### 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.
+
+### 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. {note}
+
+## Operating Voltage {toc}
+
+### 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.

+```datasheet
+label: Electrified Hardware Operating Voltage
+type: radio
+options:
+ - "24 VDC"
+ - "12 VDC"
+default: "24 VDC"
+```
+
+### 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. {note}
+
+### 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 [[sync/access-control-systems]] can be sized to hold the voltage at the device within the manufacturer's stated range under its rated load.
+
+### 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. {note}
+
+### 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.
+
+## Fire Alarm Release {toc}
+
+### 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.
+
+### 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.
+
+### The Contractor shall coordinate the relay contacts, the release circuit conductors, and the device quantities with the fire alarm installer working under [[sync/fire-alarm-systems]], and the release point shall be recorded at the pre-installation conference.
+
+### 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.

+# Accessible Opening Requirements {toc}
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## The force required to operate operable hardware on an accessible route shall not exceed 5 lbf.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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. {note}

+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## 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.
+
+## The Contractor shall coordinate the latch-side wall space at each opening with the tactile signage installed under [[sync/signage-and-egress-markings]], so that no stop, holder, or leaf in its open position obstructs the sign.
+
+## 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.
+
+## 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.
+
# Field Quality Control {toc}
−## Every opening is verified for operation, force, and life-safety function before acceptance. {note}
+## 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.
−## Each opening shall be operated through a full cycle to confirm the latch, lock, closer, and seals function as specified.
+## 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.
−## Opening force and closer sweep timing shall be measured and recorded for every accessible-path opening, and any opening exceeding the ADA limits shall be re-adjusted.
+## 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.
−## Fire-rated openings shall be tested for positive latching and proper closing on every cycle, and any opening that fails to latch shall be corrected before acceptance.
+## 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.
−## Electrified hardware shall be functionally tested with the access control and fire alarm systems to confirm correct fail-safe or fail-secure operation and fire-alarm release.
+## 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.
−## Fire door assemblies shall be functionally inspected annually after acceptance, per NFPA 80, with results documented and retained by the Owner.
+## The cost of retesting an opening that fails a field test, and of the trades attending the retest, shall be borne by the Contractor.
+## 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. {note}

# Delivery, Storage, and Handling {toc}
−## Hardware shall be delivered in the manufacturer's original packaging, individually marked with the opening number and hardware set it serves.
+## 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.
−## Hardware shall be stored in a clean, dry, secure area and protected from weather, dust, and theft until installation.
+## 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.
−## Keys and cores shall be kept under the Owner's or hardware supplier's secure control and shall not be left at the installation area.
+## 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.
+## 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. {note}
+
# Warranty {toc}
−## Door closers shall carry a manufacturer warranty against defects in material and workmanship for a minimum of 10 years.
+## Each hardware manufacturer shall warrant its products against defects in materials and workmanship for not less than the period indicated in the datasheet.
−## Exit devices and locksets shall carry a manufacturer warranty for a minimum of 3 years.

−# Spare Parts {toc}
+## 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. {note}
−## The Owner shall be furnished with spare keys and maintenance items so the facility can be operated and serviced after handover.
+## 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.
−## The Contractor shall furnish spare keys in the quantity established by the keying schedule, delivered directly to the Owner.
+## 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.
−## The Contractor shall furnish a maintenance kit of closer adjustment tools, spring cartridges, and seal stock as recommended by the manufacturer.
+## 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.
+## 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.
+
+## The hardware supplier shall furnish at closeout a consolidated summary listing, for every product on the project, the warranty period and the service contact.
