It is used for applications above freezing temperature of water. In this system, pressurized water is kept ready in the pipes. With the effect of the heat generated by the fire, the sprinkler explodes and the water hits the reflector in the sprinkler and the water is delivered to the fire scene. While the pressurized water system is fed continuously, it also fills the delay cell at the same time. After the cell is full, the pressure switch on the cell is triggered. The pressure switch transmits alarm information to the automation system. The water reaches the motor gong and causes a mechanical alarm.
