Sprinkler Heads Fire is the collective term for a variety of systems designed to detect and suppress fires. The most common type of sprinkler heads fire uses one or more spray water nozzles, or “heads”, to discharge fire extinguishing agents such as water or pressurized air. When heat is detected by the sprinkler head, a valve releases the stored liquid in order to douse the flames. Modern day sprinkler heads fire are used extensively in commercial buildings, warehouses, and other places where large fires could potentially be a safety hazard. This efficient fire protection system offers quick response time, with the ability to activate within seconds after a fire starts, and can even minimize property damage due to the minimal amount of water dispersed when it’s in operation.
