Abstract
A portable alarm is described wherein an alarm indication is obtained from remotely accessible areas. A flexible alarm event sensor is placed in the area sought to be protected. Incremental movements of the event sensor are detected and cause motion of a hub to enable a trigger element, which normally restrains an actuator, to be pivoted aside. The movement of the trigger element enables the actuator to be released to register indication of an alarm such as activating an acoustic sound source or the closure of a switch and the like. An alternate embodiment for a trigger mechanism in accordance with the invention is described.
