Fireguard Alarm Check valve is a doubled 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 isntallation 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 th alarm valve to open, allowing continuous flow of water into the system and transmittal
of alarm, both electrical and mechanical.
