One of the most dependable and effective fire fighting systems with very low maintenance costs is the sprinkler fire protection system. This system's benefit is that it can identify and put out fires on its own. A water supply system that delivers sufficient pressure and flow rate to a water distribution piping system, onto which fire sprinklers are connected, makes up a fire sprinkler system, an active fire defence mechanism. When a fire's effects are noticed, such as when a certain temperature has been reached, a sprinkler releases water.
