Abstract

An alarm system for detecting intrusion into a premises having telephone service over a telephone line, comprising a plurality of wireless sensors arranged in an area to be monitored for generating unique coded wireless signals indicating an alarm condition upon detection of an intrusion, and an alarm module connected to the telephone line for detecting the unique coded wireless signals and in response causing at least one telephone to ring and to provide notification of the alarm condition on a specified one of the sensors.

Claims

1. An alarm system for detecting intrusion into a premises having telephone service to at least one telephone over a telephone line, comprising:

a plurality of wireless sensors arranged in an area to be monitored for generating unique coded wireless signals indicating an alarm condition upon detection of an intrusion; and

an alarm module connected to said telephone line for detecting said unique coded wireless signals and in response providing a notification over said telephone line of said alarm condition on a specified one of said sensors.

2. The alarm system of claim 1 wherein said plurality of wireless sensors are radio frequency identification (RFID) devices.

3. The alarm system of claim 1 wherein said plurality of wireless sensors are Bluetooth devices.

4. The alarm system of claim 1 wherein said plurality of wireless sensors are 802.11 devices.

5. The alarm system of claim 2, 3 or 4, wherein each of said sensors includes an alarm switch for activating generation of said unique coded wireless signals in response to said alarm switch being actuated by an intruder.

6. The alarm system of claim 2, 3 or 4, wherein each of said sensors includes a self-test switch for activating generation of said unique coded wireless signals in response to said self-test switch being actuated by a user thereby verifying detection of respective ones of said sensors by said alarm module.

7. The alarm system of claim 1 wherein said alarm module includes a ringing generator for causing said at least one telephone to ring according to a predetermined pattern indicating said alarm condition.

8. The alarm system of claim 1 wherein said alarm module includes a tone generator for generating an audible signal over said at least one telephone indicating said specified one of said sensors.

9. The alarm system of claim 1 wherein said alarm module includes a speech generation system for providing a spoken alarm message over said at least one telephone indicating said specified one of said sensors.

10. The alarm system of claim 1 wherein said alarm module includes an alarm call generator for placing a telephone call outside of said premises to provide notification of said alarm condition on said specified one of said sensors via one of either a speech generation system for providing a spoken alarm message or a tone generator for generating an audible signal.

11. The alarm system of claim 1 wherein said alarm module includes a DTMF tone detector to facilitate programming of said module and dialer functionality over said at least one telephone.

12. The alarm system of claim 1 wherein said alarm module is connected to said telephone line where the line enters said premises.

13. The alarm system of claim 1 wherein said alarm module is integrated with said at least one telephone and connected to said telephone line within said premises.

14. The alarm system of claim 1 wherein said alarm module is connected between said at least one telephone and said telephone line within said premises.

15. Method of programming the alarm system of claim 6, comprising:

detecting within said alarm module user entry of a predetermined DTMF code in said at least one telephone;

signaling an acknowledgement of said DTMF code by said alarm module to said at least one telephone;

generation of a said unique coded wireless signal at said specified one of said sensors responsive to actuation of said self-test switch; and

detecting said unique coded wireless signal within said alarm module and in response enabling further detection of said unique coded wireless signals for indicating said alarm condition.

16. The method of claim 15 wherein said signaling of the acknowledgement of said DTMF code comprises generation of an audible signal.

17. The method of claim 16 wherein said audible signal is a pattern of tone beeps.

18. The method of claim 16 wherein said audible signal is a voiced communication.

19. A method of operating an alarm system to provide persistent filtering, comprising:

arming at least one alarm sensor capable of generating a unique coded signal indicating an alarm condition;

monitoring said at least one alarm sensor for said unique coded signal; and

indicating an alarm condition in the event that said alarm condition persists for a predetermined period of time.

20. A method of operating an alarm system to provide activity filtering, comprising:

arming at least one alarm sensor capable of generating a unique coded signal indicating an alarm condition;

monitoring said at least one alarm sensor for said unique coded signal and determining a rate of generation of said unique coded signal; and

indicating an alarm condition in the event that said rate of generation of said unique coded signal falls below a predetermined rate.

21. A method of operating an alarm system to provide timed activity filtering, comprising:

arming at least one alarm sensor capable of generating a unique coded signal indicating an alarm condition;

monitoring said at least one alarm sensor for said unique coded signal; and

indicating an alarm condition in the absence of generation of said unique coded signal within a predetermined time interval.

22. A method of operating an ancillary alarm system connected to a primary alarm system, comprising:

arming at least one wireless alarm sensor capable of generating a unique coded signal indicating an alarm condition;

monitoring said at least one alarm sensor for said unique coded signal; and

transmitting an alarm signal to said primary alarm system upon detecting said unique coded signal.
