Dry Alarm Valve Y-4015

The Dry Alarm Valve, dry pipe sprinkler system is designed for places where pipes and sprinklers may be exposed to freezing temperatures, such as unheated warehouses, garages, parking lots, attics and shops. The sprinkler installation uses air or nitrogen gas instead of water. 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 clapper. The differential ratio in the system is disrupted due to the sprinkler exploding in case of any fire and causes the clapper 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 water motorized gong and causes the mechanical alarm to sound.

Specially designed for all dry pipe systems. Externally reset. Suitable for vertical use only. Semi-assembled.
