An automatic fire sprinkler system consisting of a water supply system (pumps and tank or mains water), a network of pipes (steel, plastic and other alloys) and fire sprinkler heads spaced at regular intervals throughout the protected premises. Fire sprinklers in the past were used only in warehouses, factories, offices and other commercial premises. But in recent years they are regularly installed in family dwellings, care homes, student accommodation, hospitals, libraries and historical remises.
Fire sprinkler systems are used worldwide, with well over 40 million sprinkler heads fitted each year. Automatic fire sprinkler systems are the most widely used fire protection system throughout the world. Sprinklers are designed to put a little water as possible on the seat of a fire at a very early stage of development.
