The wet alarm valve is designed for applications where there is no risk of the water freezing. When a sprinkler is activated by a fire, the water kept pressurized in the pipes
is discharged onto the fire area. While the pressurized water system is fed continuously, it also fills the retard chamber
at the same time. Once the chamber is full, the pressure switch on the chamber is triggered. The pressure switch transmits the alarm
signal to the fire alarm system or building automation system. After the pressure switch is triggered, the water reaches the water-motor gong and sounds a mechanical alarm.
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 fed continuously, 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.
