Dry Alarm Valve

After the sprinkler activated by the fire the air in the sprinkler system is discharged from the sprinkler system. The water is sent to the location of the fire. By the time the clapper opens the water also is sent to the pressure switch and the switch sends alarm information to the fire warning system or automation system. After the switch is activated, the water is delivered to the water-motor gong and releases a mechanical alarm.
