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.
* Ductile iron body confirming to ASTM A536
* Double seated clapper design
* Compact design and small foot print
* Smooth operation under variable pressures

The Grooved end and wafer type butterfly valves are indicating type designated for use in
fire protection systems where a visual indication is required as to whether the valve is open
or closed. Valve features a compact and lighter body with factory installed internal switches
having SPDT contacts. The supervisory switches transfer their electrical contacts when there
is movement from the valves normal open position during the first two revolutions of the
handwheel.
