Alarm Check Valve is core element in wet pipe fire sprinkler systems. It serves a dual purpose which prevents a reverse flow of water (non-return), also provides for the use of the water motor gong. Meanwhile, in the event of variable pressure condition, false alarm is prevented with provision of retard chamber at the external bypass.

Deluge valve is a quick release, hydraulically operated diaphragm valve used in a deluge system. And deluge system is used in conditions that require quick application of large volumes of water, such as storage tank, equipment pits, conveyor protection, etc.
 

When the fire fighting system starts increasing pressure, water will flow into the system until reaching a balance between the water supplying with the system pressure. And the alarm check valve can put pressure on the fire pumps valve to prevent the water backflowing. Once the pressure comes to balance, the alarm check valve will be in operation state, and the middle chamber of its seat ring will be sealed. So if the alarm check valve was set at maintenance state, there will no alarm port to the alarm facility (alarm pressure switch).
