Abstract

A programming apparatus for generating and retaining a security disarm code (SDC) for use in a security system for protecting items of merchandise has a housing and a logic control circuit located within the housing. The control circuit includes a controller for generating the SDC, a memory for storing the generated SDC and a wireless communication system for interfacing with a programmable key used for operating a security device attached to an item of merchandise. A visual display includes a plurality of LEDs which indicate the status of the logic control circuit. The SDC is generated initially as a random SDC by the programming apparatus, which SDC is retained in the controller of the apparatus for the life of the programming apparatus.

Claims

1. An apparatus for generating and retaining a security code for use in a security system for protecting items of merchandise, said apparatus comprising:

a housing;

a logic control circuit located within said housing, said control circuit including;

a) a controller for generating the security code;

b) a memory for storing the generated security code;

c) a wireless communication system for interfacing with a programmable key used for operating a security device attached to an item of merchandise; and

d) a visual display for indicating the status of the logic control circuit.

2. The apparatus defined in claim 1 wherein the memory for storing the security code is a non-volatile memory enabling said memory to survive power interruptions.

3. The apparatus defined in claim 1 wherein the visual display includes a plurality of LEDs.

4. The apparatus defined in claim 3 wherein a first of said LEDs is activated when power to the station is ON.

5. The apparatus defined in claim 4 wherein a second of said LEDs flashes for a period of time when wireless communication is started with the programmable key.

6. The apparatus defined in claim 5 wherein a third of said LEDs is activated when a programming failure occurs.

7. The apparatus defined in claim 1 wherein the housing has a internal chamber;

and in which the logic control circuit is a printed circuit board located within the housing chamber.

8. The apparatus defined in claim 1 wherein the housing includes a base plate, a main housing shell mounted on the base plate, an internal spacer mounted with the housing shell, and a cover plate mounted over and enclosing said housing shell.

9. The apparatus defined in claim 8 wherein a mechanical fastener secures the base plate to the housing shell.

10. The apparatus defined in claim 8 wherein a mechanical fastener secures the base plate to a supporting structure.

11. The apparatus defined in claim 8 wherein the housing shell is formed of an infrared clear plastic material.

12. The apparatus defined in claim 1 including a mechanical key activated ON/OFF switch mounted in the housing and operatively connected to the logic control circuit.

13. The apparatus defined in claim 1 including a key port formed in the housing for receiving the programmable key therein, said port being proximate the wireless communication system of the control logic circuit.

14. The apparatus defined in claim 1 wherein the security code is a code for disarming the security device.

15. A security system for protecting an object comprising:

a key operated security device for attachment to the object, said security device containing a security code;

a key programmed with the security code to disarm the security device when placed in close proximity thereto;

a programming station containing a wireless communication system for programming the security code into the key;

a wireless communication system in the key for comparing the security code of the key to the security code of the security device; and

a timer in the key for automatically invalidating the security code stored in the key after a predetermined time period.

16. The security system defined in claim 15 wherein the programming station randomly generates the security code when initially actuated by the key and which stores said security code permanently in a security code memory in the programming station.

17. The security system defined in claim 15 wherein the wireless communication system of the programming station uses infrared (IR) or radio frequency (RF) wavelengths for programming the key with the security code.

18. In combination, a programmable key for operating a security device attached to an item of merchandise and a programming station, said programming station comprising:

a housing;

a logic control circuit located within said housing, said control circuit including a memory for storing a security code and a communication system for transferring the security code to the programmable key used for operating the security device; and

a visual display for indicating the status of the logic control circuit of the programming station.

19. The combination defined in claim 18 wherein the logic circuit includes a controller for generating the security code.

20. The combination defined in claim 18 wherein the communication system is a wireless communication system.
