Abstract
Fast acting actuation system which is especially suitable for automatic sprinklers and other emergency devices. The system includes a fast-acting low mass thermally responsive element comprising a pair of thin metal strips soldered together, a percussion member such as a firing pin which is released when the solder in the thermally responsive element melts, and an actuator, preferably a radially expandable explosive actuator, which is initiated by the firing pin. The actuator when initiated causes rapid actuation of the automatic sprinkler or other device.
