Deluge fire suppression systems use an open distribution pipe network, typically connected to a number of valves allowing for the relevant suppression agent to be released in specific areas. These systems are suitable for high-hazard areas where fire may spread rapidly or where water damage is not a concern.
Deluge fire suppression systems work by using an empty pipe system, meaning there is no water or other agent stored within the piping network. The water or agent is instead stored behind a control valve. A typical deluge system has a control valve, a dedicated water or agent supply, and a detection system.
When the detection system senses a fire, it activates the control valve, which opens and releases the water or agent into the piping network. The water or agent then flows through the open nozzles or sprinklers and discharges onto the fire. The system operates as one unit, meaning all the nozzles or sprinklers are activated at once.
