The dry pipe sprinkler system is designed for locations where pipes and sprinklers may be exposed to freezing temperatures, such as unheated warehouses, garages, parking lots, attics and shops. In the sprinkler installation, instead of water, there is air or nitrogen gas. The differential type dry alarm valve prevents the entry of air at low pressure and water at high pressure into the system, thanks to its special flap. In the event of a fire, due to the bursting sprinkler, the differential ratio in the system deteriorates and causes the damper to open. The pressure switch transmits alarm information to the fire alarm system or automation system. After the pressure switch is triggered, the water reaches the motor gong and causes the mechanical alarm to sound.
