Alarm Valve

Alarm Valve is a double seated clapper check valve
with grooved seat design, which ensures positive
water flow for alarm operation and is designed for
installation in wet pipe sprinkler system. External
bypass prevents false alarm under all supply pressure
condition. In the event of variable pressure condition,
false alarm is prevented with the provision of retard
chamber, thus the design allows for installation under
both variable and constant supply pressure condition.
Operation of one or more automatic fire sprinklers
causes the water to flow into the sprinkler system
causing the alarm valve to open, allowing continuous
flow of water into the system and transmittal of
alarm, both electrical and mechanical.
