Deluge Systems

Deluge systems are systems that have open sprinklers – the heat-sensing operating element is removed or specifically designed to be open so that all sprinklers connected to the water piping system are open. Deluge systems are used for special hazards where rapid fire spread is a concern, as they provide a simultaneous application of water over the entire hazard, and are commonly seen as preventive measures to prevent egress of fire from an external source, such as high-rise windows, warehouse bay entries and openings in a fire-rated wall. Water is not present in the piping until the system operates.
