1.1 Deluge Systems
A deluge system utilizes open sprinklers or nozzles and non-pressurized system piping. When a deluge
system is activated, all sprinklers or nozzles on that system flow water at the same time. Deluge systems are
generally associated with high hazard occupancies that require large volumes of water. Examples include ex-
posure protection, materials having high rates of heat release, conveyors, water curtains, fuel storage tanks,
electrical transformers, aircraft hangars, and chemical plants. Deluge systems require an automatic detection
system and/or manual releasing system which operates independently from the sprinkler system. A deluge
system is capable of applying water to a fire more quickly than a system utilizing temperature sensitive closed
sprinklers.
