Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. They are divided into pendent sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc.

A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price
