Abstract
A triggering device for fire and smoke alarms in which a biased pin member is held in armed position by a latch element which is releasable when a bimetallic disc senses and responds to a selected temperature condition. The response of the disc is transmitted through a ball or antifriction element to which is imparted a lateral force for moving the latch element out of engagement with the pin member. The pin member is spring biased to urge the pin member against a member serving to cause actuation of the alarm.
