Product Description
The wet alarm valve is designed for applications where the water is unlikely to freeze. The water staying pressurized in the pipes is released over the fire area after the sprinkler is activated due to fire. The pressurized water system is not only feed contionuously, but also fills in the retard chamber. After the chamber is filled, the pressure switch on the chamber is actuated. The pressure switch sends the alarm information to the fire warning system or the automation system. After the pressure switch is actuated, the water is delivered to the water-motor gong and releases a mechanical alarm.

At its basic core, a valve is going to help control water throughout a web standpipe system. This could be underground, but the majority of alarm check valves are used above ground, usually in buildings and high rises.
Because of the nature of water being corrosive, when it sits idle for any length of time it can increase corrosion of the pipes. The alarm check valves help to minimize this level of corrosion by limited the pressure within the pipes until such time as it's needed. Once activated, the alarm check valves will open, allowing the full pressure of water to fill the system.
