Abstract
An electronic device that functions as an area-intrusion informing device for announcing the unauthorized entry into an enclosure or area which has at least one access opening and closing means. The device uses components that are small for inconspicuous insertions, or for surface mounting, and preferably utilizes a dummy hinge arrangement as an electrical conductor between the various components. The device is used for access doors, windows, filing cabinets, desk draws, closets, and the like, and typically includes at least one light emitting diode, an optional numeric liquid crystal display, a timer, and alert signaling and reset components. The components act together to provide notification of illegal entry between the times of departure, and arrival, of authorized users of the enclosure or area. A simple security alert system is provided.
