scope:

This standard encompasses the design and performance requirements for 1, 1-1/4, 1-1/2 and 2 inch nominal pipe sizes (NPS) sprinkler system alarm test devices which are designed to replicate the flow of a sprinkler head.

Sprinkler system alarm test devices are devices intended to replace an assembly of components, which normally include a shut-off valve, an orifice which is usually made from an open sprinkler head with frame arms and deflector removed, a water collection waste cone, and other interconnecting pipes and fittings. The device incorporates equivalent elements into a single assembly.

Other types and sizes, including metric sizes, of sprinkler system alarm test devices may be FM Approved if they meet the requirements and intent of this standard. Sprinkler system alarm test devices of unusual design may be subjected to special tests to determine their suitability.

Purpose

This standard states Approval criteria for sprinkler system alarm testers for use in aboveground automatic fire protection systems.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
