Specifies the requirements for establishing compliance with limits of design, performance, security and durability for sprinkler and hydrant valve monitors.

This Standard specifies the requirements for valve monitors for mounting on stop valves for automatic fire prinkler systems, designed and installed in compliance with AS 2118, and fire hydrant systems designed and installed in compliance with AS 2419, to monitor the set position of the valves. If the state of a valve is changed or an attempt is made to subvert the operation of the monitor it will initiate an alarm signal.NOTE: The alarm signal is generally initiated and then transmitted via the supervisory equipment to a fire control station or a monitoring station.
