Abstract

An object that can be sensed by a motion detector is equipped with a small, battery powered transponder. A motion detector has (either internally or externally) a transceiver adapted to provide a query signal. If the object is within range of the query signal, the transponder responds with a transponder signal. The transceiver is responsive to receipt of the transponder signal to prevent the detection of motion from causing an alarm.

Claims

1. An adapter for adaptable connection to a motion detector and for communication with an alarm panel, wherein the motion detector is for placement in a protected space and provides a breach indication in response to detection of motion in the protected space, the breach indication normally causing an alarm at the alarm panel, the adapter comprising:

a) a transceiver adapted to provide an indication that a signal has been received from a transponder disposed on an object within the protected space; and

,

b) circuitry responsive to the indication provided by the transceiver that prevents the breach indication from reaching the alarm panel and causing an alarm.

2. The adapter according to claim 1 wherein the transceiver transmits a query signal in response to the breach indication, and the transponder transmits the transponder signal in response to receipt of the query signal.

3. The adapter according to claim 1 wherein the transceiver periodically transmits a query signal and the transponder transmits the transponder signal in response to receipt of the query signal.

4. The adapter according to claim 1 wherein the transceiver constantly transmits a query signal and the transponder transmits the transponder signal in response to receipt of the query signal.

5. The adapter according to claim 1 wherein the transponder transmits the transponder signal only in response to receipt of a query signal from the transceiver.

6. The adapter according to claim 1 wherein at least one of the transceiver and transponder have a range generally corresponding to the area of the protected space.

7. The adapter of claim 1 wherein the motion sensor and adapter are disposed in the same housing.

8. The adapter of claim 1 wherein the motion sensor is disposed in a motion detector housing and the adapter is disposed outside the motion detector housing.

9. The adapter according to claim 1 wherein the connection is a hard wired connection.

10. The adapter according to claim 1 wherein the connection is a wireless connection.

11. An adapter for adaptable connection to a motion detector and for communication with an alarm system, wherein the motion detector is for placement in a protected space and provides a breach indication in response to detection of motion in the protected space, the adapter comprising:

a) a transceiver adapted to provide an indication that a signal has been received from a transponder disposed on an object within the protected space; and

,

b) circuitry responsive to the indication provided by the transceiver that prevents the alarm system from responding to the breach indication.

12. The adapter according to claim 11 wherein the transceiver transmits a query signal in response to detection of motion by motion detection circuitry, and the transponder transmits the transponder signal in response to receipt of the query signal.

13. The adapter according to claim 11 wherein the transceiver periodically transmits a query signal and the transponder transmits the transponder signal in response to receipt of the query signal.

14. The adapter according to claim 11 wherein the transceiver constantly transmits a query signal and the transponder transmits the transponder signal in response to receipt of the query signal.

15. The adapter according to claim 11 wherein the transponder transmits the transponder signal only in response to receipt of a query signal from the transceiver.

16. The adapter according to claim 11 wherein at least one of the transceiver and transponder have a range generally corresponding to the area of the protected space.

17. The adapter of claim 11 wherein the motion sensor and adapter are disposed in the same housing.

18. The adapter of claim 11 wherein the motion sensor is disposed in a motion detector housing and the adapter is disposed outside the motion detector housing.

19. The adapter according to claim 11 wherein the connection is a hard wired connection.

20. The adapter according to claim 11 wherein the connection is a wireless connection.

21. The adapter according to claim 20 wherein the adapter transmits a wireless breach indication to a receiver in communication with the alarm panel only if no transponder signal has been received by the transceiver.

22. The adapter according to claim 20 wherein the adapter transmits a wireless breach indication to a receiver in communication with the alarm panel only if no transponder signal has been received by the transceiver.
