SynC · Topic
These are the standards in the SynC Standards library that cover Sprinklers. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Automatic dry-pipe sprinkler systems designed to NFPA 13, in which the piping downstream of a dry-pipe valve is held under supervisory air or nitrogen because the piping is exposed to freezing. Covers the decisions that exist only on a dry system: the dry-pipe valve and its trim, the quick-opening device, the supervisory gas source and its pressures, water delivery time, pitch and low-point drainage, the corrosion consequences of a wet-and-dry pipe interior, the provisions for piping in refrigerated spaces, and the trip test and 24-hour air leakage test that prove the installation.
Automatic sprinkler systems designed to NFPA 13 in which the piping downstream of a pre-action or deluge valve is normally dry and water is admitted by a releasing control unit acting on a fire detection signal rather than by the opening of a sprinkler alone. Covers the decisions that exist only on these systems: the system type (non-interlock, single-interlock, and double-interlock pre-action, and deluge), the releasing detection and its initiating logic, the releasing control unit and its listing for releasing service, the release actuation of the valve, manual release and any release delay, the auxiliary functions tied to a release, the pre-action or deluge valve and its trim, the supervisory gas and its supply on a pre-action system, the water delivery time of a double-interlock system, the open discharge devices and zoning of a deluge system, and the trip test, releasing sequence tests, and air leakage test that prove the installation.
Automatic wet-pipe fire sprinkler systems designed under NFPA 13 for commercial, institutional, industrial, high-rise, and multi-family residential buildings, together with the requirements common to every automatic sprinkler system that the dry-pipe and pre-action layers build on. Covers occupancy hazard classification, the design approach, design density and area, hose stream allowance and water supply duration, the water supply basis, pipe arrangement, the hanging and seismic bracing policy for sprinkler piping, sprinkler selection (type, thermal response, temperature rating, K-factor, finish, and corrosion resistance), flexible sprinkler connections, the wet-pipe riser, floor and zone control assemblies, alarm and supervisory provisions, freeze-exposed pockets on a wet system, acceptance testing, warranty, and the spare sprinkler cabinet.
