CD Waterflow Alarm Valve System
Unique Fire CD waterflow alarm valve system Unique Fire CD alarm valve UL listed sprinkler alarm valve
The CD Waterflow Alarm Valve System is installed in a sprinkler system to actuate a fire alarm when the flow of water from the sprinkler system is more than that of a single sprinkler. The water supply pressure causes an alarm valve clapper to open and the resultant water flow into the alarm line activates the alarm.
Fluctuations and surges in water mains supply pressure is prevented by a separate bypass connection and by first routing the water through a retard chamber.
