Reliable Model E and E3 Alarm Check Valves act as a water flow alarm initiating device in wet pipe sprinkler systems. When water flows in the sprinkler system due to the operation of one or more automatic fire sprinklers, the alarm valve opens allowing continuous flow of water into the system. The alarm valve clapper incorporates a normally unpressurized intermediate chamber connected to an alarm line. When the clapper lifts due to water movement in the system, the intermediate chamber and alarm line pressurize, activating water flow devices such as mechanical (water motor) bells and/or pressure switches. The alarm line may also be used to operate foam concentrate hydraulic ball valves on foam systems.
The design of the Model E and E3 Alarm Check Valve allows for installation under both variable and constant supply pressure conditions. The valve trim incorporates a bypass between the water supply and the wet pipe system. When pressure surges in the waters supply occur, the trim allows a small amount of water to bypass the clapper limiting the potential of false alarms.
