A fire sprinkler system is an active fire protection method that consists of a water supply system that provides adequate pressure and flow rate to a water distribution piping system that connects fire sprinklers. Although previously only used in factories and large commercial buildings, systems for homes and small buildings are now affordable. Fire sprinkler systems are widely used around the world, with over 40 million sprinkler heads installed each year. Despite the fact that fire sprinkler systems are a life-saving system, they were not designed to protect buildings that had fires and were completely protected by fire sprinkler systems.
