Deluge Fire Sprinkler Systems

The arrangement of deluge fire sprinkler system piping is similar to a wet or dry pipe system with two major differences:

A. Standard sprinklers are used, but they are all open. The activating elements have been removed so that when the control valve is opened water will flow from all of the sprinklers simultaneously and deluge the area with water.

B. The deluge valve is normally closed. The valve is opened by the activation of a separate fire detection system.

Deluge systems are used where large quantities of water are needed quickly to control a fast-developing fire. Deluge valves can be electrically, pneumatically, or hydraulically operated.
