Devices for sprinkler system
Alarm and control equipment for sprinkler system. Water remains pressurized in the pipes and is released over the fire area after the sprinkler is activated by the fire.

After the pressure switch is activated, the water passes to the water motor gong and triggers a mechanical alarm.
