scope:

This standard encompasses the design and performance requirements for quick opening devices (accelerators and exhausters) for use in dry automatic sprinkler fire protection systems.

Approval standards are intended to verify that the product described will meet stated conditions of performance, safety, and quality useful to the ends of property conservation.

Purpose

This standard states Approval requirements for quick opening devices (accelerators and exhausters) used with dry pipe valves in dry automatic sprinkler fire protection systems to hasten the operation of dry pipe valves when one or more sprinklers operate. These devices are also used on preaction sprinkler systems to hasten the operation of automatic water control valves. This standard addressed both mechanical and electronic devices.

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.
