Abstract:
1. An early suppression fast response fire protection system comprising: sprinkler piping system including at least one sprinkler head assembly and at least one automatic vent venting gas in said sprinkler system piping when said sprinkler system piping is filled with fire suppression solution; a water supply system; a check valve having a water supply inlet and an outlet, said outlet of said check valve in fluid communication with said sprinkler piping system and said water supply inlet in selective fluid communication with said water supply system; a fire suppression solution supply system in fluid communication with said sprinkler piping system, said check valve isolating said fire suppression solution from said water supply unless a fire condition occurs; a pressure detector detecting the pressure of the fire suppression solution in said sprinkler piping system; a flow detector detecting the flow of water from said water supply system; and a control system in communication with said flow detector and said pressure detector, said control system controlling the flow of said fire suppression solution to said sprinkler piping system and maintaining the pressure of said fire suppression solution in said sprinkler piping system unless said flow detector detects the flow of water from the water supply system in which case said control system stops the flow of said fire suppression solution to said sprinkler piping system to limit the discharge of fire suppression solution from the fire protection system.
