  • Patent number: 4001805
    Abstract: The present invention is in an alarm system including a sound generator, a sound responsive switching circuit and an alarm. The sound generator includes an element capable of snapping rapidly from one position to another upon change in a monitored condition. The switching circuit includes a sound activated switch which is energized in response to a sound of predetermined frequency eminating from the sound generator. This creates an electrical signal that passes through the switching circuit to actuate the alarm. The alarm may be audible and/or visual and the sound activated switch after a predetermined time may deenergize the audible alarm. The sound generator is positioned at the location where the change in condition is to be sensed. All other parts of the system are adapted to be spaced remotely therefrom.
