Alarm Valves
Dry Alarm Valve The dry pipe sprinkler system is used in unheated and frost-prone areas to prevent damage to the water and sprinklers in the fire suppression system. In this system, the pipes are filled with pressurized air or inert gas. When a fire occurs and the sprinklers activate, the air pressure drops, causing the dry alarm valve clapper to open, allowing water to flow and suppress the fire. The dry alarm valve is preferred in areas at risk of freezing, such as parking garages, warehouses, attic spaces, workshops, manufacturing facilities, hotels, waste collection centers, and shopping malls. The upper part of the valve is pressurized with air or gas, while the lower part is pressurized with water. The time for water to discharge from the most distant point in the system should not exceed 60 seconds.
