 Dry pipe sprinkler systems are designed for locations where the pipes and sprinklers may be exposed to freezing temperatures, such as unheated warehouses, garages, car parks, 

attic spaces and stores.  The sprinkler piping contains air or nitrogen gas instead of water.  Thanks to its special 

clapper, the differential-type dry alarm valve uses low-pressure air to keep high-pressure water from entering the system. When a sprinkler bursts in a fire, 

the differential ratio in the system is upset, causing the clapper to open. The pressure switch sends the alarm 

signal to the fire alarm system or the automation system. After the pressure switch is triggered, the water reaches the water motor gong and sounds a mechanical alarm.

  Dry Pipe Sprinkler Systems are designed for applications where piping and sprinklers are subjected to freezing temperatures, such as unheated 

warehouses, parking garages, store windows, attic spaces, or loading docks. The sprinkler system contains gas instead of water. The dry pipe valve 

with its special clapper holds back the pressurized water by means of low air pressure. In case of fire, a sprinkler activates and the differential of the system breaks down 

and causes the clapper to open. After the sprinkler is activated by the fire, the air in the sprinkler system is discharged from the system. The water 

is sent to the location of the fire. As the clapper opens, the water is also 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.
