ABSTRACT:
A combined trigger and concealing device for an automatic sprinkler head comprises a first plate attached to a second plate by a heat fusible material in a partially overlapping manner. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler head. The trigger device depends a preselected distance from the bottom of the sprinkler head body and has an outer dimension which causes the trigger device to conceal the internal components of the sprinkler head from view. An annulus defined between the periphery of the device and the bottom of the sprinkler head permits heat energy to be received by the inner surface of the trigger device. Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This uniform thermal conduction minimizes the response time of the automatic sprinkler head while maintaining a highly aesthetic appearance.
