Deluge Fire Protection System
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
Deluge systems are used in high hazard areas such as power plants, aircraft hangars, and chemical plants. These systems are very effective in hazardous areas because they release water or another fire suppressant to all the open sprinkler heads simultaneously. This total flood method douses a fire before it has the chance to grow uncontrollably.
