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.

Claims

1. An access annunciator device for informing a user of unauthorized entry within a window, filing cabinet, desk drawer, closet, lunch pail, heavy duty field equipment, areas enclosed by automotive doors, automotive lids or automotive hoods, or within an enclosure closed by an access doors wherein said access annunciator device is surface mounted on said access door or mounted of an access door frame, or within an enclosure having an access opening covered by a lid, which access annunciator device comprises an access switch which access switch provides an access signal when said access switch is activated, an activation counter and counter memory means which counts the number of access signals received, an alert system which remains silent on a first and a second access signal, and which will first energize an alert signaling means on a sequential third access signal, and an alert signaling means for generating an alert signal when activated by said alert system.

2. A device as claimed in claim 1 wherein said counter memory means has a reset means.

3. A device as claimed in claim 1 wherein said alert signal is transmitted wirelessly to a remote alert display unit.

4. A device as claimed in claim 1 wherein said alert signal energizes an alert device.

5. A device as claimed in claim 4 wherein said alert device is an audible, visual, or vibratory signal.

6. A device as claimed in claim 1 wherein said access switch is a momentary access switch.

7. A device as claimed in claim 6 wherein said momentary access switch is a contact switch, a reed switch, a relay switch, or a light sensor switch.

8. A device as claimed in claim 1 wherein said alert system comprises a pulsed activated switching means.

9. A remote display unit for use with an access annunciator as claimed in claim 1 wherein said remote display unit is utilized to control said access annunciator and/or receive alert signals from said alert signaling means.
