Patent ID: 6848513

Claim:
A trim assembly for a fire protection system valve, the fire protection system valve having an inlet in communication with a fire suppressant fluid supply line and an outlet in communication with sprinkler system piping, the fire protection valve having a priming chamber and a clapper assembly, the clapper assembly closing communication between the inlet and the outlet when the priming chamber is pressurized and the clapper assembly opening communication between the inlet and the outlet when the priming chamber is depressurized to control the flow of fire suppressant fluid from the fire suppressant fluid supply line to the sprinkler system piping, said trim assembly comprising: a mounting member; a trim piping assembly mounted to said mounting member, said trim piping assembly comprising: a priming line having an inlet for receiving priming fluid from the fire suppressant fluid supply line and an outlet for delivering priming fluid to the priming chamber of the fire protection system valve; at least one component responsive to an input chosen from a control signal and a pressure differential, said component controlling the flow of the priming fluid between said inlet and said outlet of said priming line in response to said input for controlling the delivering of priming fluid to the priming chamber of the fire protection system valve to thereby open the fire protection valve; and a discharge outlet, said priming line discharging the priming fluid to the discharge outlet when said component redirects the flow of priming fluid away from said outlet of said priming line; and said inlet and said outlet of said priming line and said discharge outlet provided at said mounting member.
