Abstract:
A discharge head for use in a fixed fire extinguishing system including a body member having an inlet and an outlet for receiving and discharging fire extinguishant, and a plug member normally retained in the body member by a latching assembly for preventing the flow of extinguishant through the body member. The latching assembly is adapted to release the plug member in response to a fire occurring in the vicinity of the body member, thus permitting the discharge of the plug member from its flowpreventing position. A fusible member cooperates with the plug and is adapted to fuse at a predetermined temperature to permit the flow of extinguishant through the body member independent of the operation of the latching assembly.
