A Water Deluge System consists of a network of dry pipework and open nozzles. Water is introduced into the system by means of a fast acting specifically engineered deluge valve. The "deluge valve" is the automatic water control valve that is used to control water flow into deluge, preaction and special types of fire protection systems in response to a fire.
Deluge fire protection systems are normally used in special hazard installations where an entire area application of water is required for protection. Typical applications may include flammable liquid handling and storage areas, aircraft hangars, and other high hazard instrallations where water is the most effective extinguishing agent. Deluge systems employ open sprinklers or spray nozzles attached to a piping system. The system is connected to a water supply through the deluge valve. This valve is opened by the operation of a fire detection system installed in the same areas as the open sprinklers or nozzles. Deluge systems may be activated by wet or dry pilot sprinklers, or electric detectors. When the deluge valve opens, water flows into the piping system and discharges from all open sprinklers and nozzles.
The systems can be either automatic or manually operated. The design requirement and applied water density (flow per unit area) will depend on the specific risk. Water is applied at a rate which will overcome the predicted fire hazard associated with the fuel load. Systems are engineered in accordance with international and locally recognised standards.
