  • Alarm system activated by buzzers
    Patent number: 4520349
    Abstract: In alarm systems a central control unit has been activated by sensors at the entrances of a home. The sensors signal the central control unit through extensive wiring or by a radio transmitter at each entrance. In this invention the signalling is done by an inexpensive buzzer at each entrance providing a definite distinct sound to be identified. The central control unit in this invention is sensitive to be activated by the buzzer of a distant entrance but it is not activated by ordinary sounds in an unoccupied home.
