The Reliable model E alarm check valve acts as a water flow alarm device in wet pipe sprinkler systems. The design allows for installation under both variable and constant supply pressure conditions. 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 and a transmission of an alarm, both electrically and mechanically.
