ABSTRACT:
An electronic device is provided that functions as an area-intrusion informing embodiment for announcing the unauthorized entry into an enclosure or area which has at least one access opening and closing means. The invention is not intended to replace conventional alarm systems, but to provide its' own unique functional identity. The invention comprises components that, when installed, will function as a tamper proof device, whose components are packaged in a combination of at least one container, to facilitate remoteness, and substantially small for inconspicuous insertions, or surface mounting. The Access Annunciator is ideal for access doors, windows, filing cabinets, desk draws, closets, bottles, handbags, briefcases, envelopes, boxes and the like, and typically includes at least one light emitting diode, an optional numeric liquid crystal display, a timer, an alert signaling means, and resetting means. 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, or provide an indication of unauthorized access to a room or to materials contained within an enclosure. A simpler security alert system is provided.
