ABSTRACT:
A sprinkler assembly for controlling a fire situation includes at least one fluid conduit defining a flow passage including an inlet for receiving a fluid from a fluid source and at least one outlet for discharging the fluid, and a dispensing mechanism such as an open or closed sprinkler head for distributing water to a selected location. A fluid control apparatus is provided including a valve assembly having a valve seal which is moveable between a closed position blocking fluid flow through the conduit and an open position causing fluid flow through the conduit. The fluid control apparatus further includes an actuating mechanism including a valve actuator which is operatively connected to the valve assembly for causing movement of the valve seal to the open position upon release of the sealing force. A sensing mechanism is operatively connected to the valve assembly, the sensing mechanism being thermodynamically responsive to at least one of heat, smoke, infrared radiation and ultraviolet radiation emitted by a heat source.
