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 ...
Fire sprinklers can be automatic or open orifice. Automatic fire sprinklers use a fusible element that activates at a predetermined temperature. The fusible element either melts or has a frangible liquid-containing glass bulb that breaks, causing the water pressure in the fire sprinkler piping to push a plug out of the sprinkler orifice ...
The first fire extinguisher patent was issued to Alanson Crane of Virginia on Feb. 10, 1863. [12] The first fire sprinkler system was patented by H.W. Pratt in 1872. But the first practical automatic sprinkler system was invented in 1874 by Henry S. Parmalee of New Haven, CT. He installed the system in a piano factory he owned.
A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation, the water pressure can be boosted by means of a fire pump.
In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
