Abstract: The discharge outlet plug of a fire extinguishant nozzle is retained by an external lever system that is conditioned by the operation of a heat fusible means in response to the presence of a first temperature rise to permit release of the plug under fluid pressure in the nozzle. An overriding beam arrangement is provided to prevent release of the plug unless the nozzle fluid pressure exceeds a predetermined pressure floor, and in some forms a temperature responsive override arrangement is provided to disable the overriding beam arrangement in the presence of a materially higher temperature rise to permit the plug to be expelled by fluid pressures below the pressure floor.
