Deluge & Preaction Systems

Deluge System

Features & Quick Specs

Deluge Systems are normally used in special hazard installations where water must be applied to an entire area
for protection. They use open sprinklers or spray nozzles attached to a piping system connected to a water supply
through the deluge valve. The deluge valve is used to control water flow into deluge, preaction, and special types of fire protection systems in response to a fire. This valve is opened by a fire detection system installed in the same areas.
Preaction Systems are used to protect areas where water damage from damaged sprinklers or piping must be avoided. A prealarm of a possible fire allows time for alternate fire extinguishment prior to a sprinkler discharge. They are designed for applications such as refrigerated areas that require maximum protection against inadvertent operation of the sprinkler system.
