Abstract

An alarm reporting system includes a control unit which services a supervised derived channel communicator, and a one-way radio communicator (preferably via the cellular telephone network), to provide for interactive operation of the derived channel unit and the radio transmitter according to alarm conditions which may arise at the premises, and the existing condition of the equipment comprising the system. The system is capable of communicating with a central monitoring facility, or mobile units (patrol vehicles or service vehicles) associated with the central monitoring facility, for enhanced security of the monitored premises.

Claims

1. A supervised, interactive alarm reporting system for providing communication between an alarm device associated with a premises and including means for controlling operations of said alarm device responsive to signals received from a plurality of sensors associated with said premises and means for dialing a selected number responsive to signals received from said controlling means, and a central facility for monitoring the alarm device at said premises, comprising:

first means for establishing communication between the controlling means of said alarm device and said central facility using wired communicating lines;

second means for establishing communication between the dialing means of said alarm device and said central facility using radio transmissions; and

means connecting said first means and said second means for controlling operation of the first means and the second means according to the condition of at least said first means;

wherein said connecting means is at all times connected for controlling operation of said first means and said second means according to the condition of at least said first means and independent of the state of said alarm device.

2. The system of claim 1 wherein said first means is a derived channel unit.

3. The system of claim 2 wherein said derived channel unit is supervised.

4. The system of claim 2 wherein said first means operates via a switched telephone line network.

5. The system of claim 1 wherein said second means is unsupervised.

6. The system of claim 5 wherein said second means is a transmitter only.

7. The system of claim 5 wherein said second means operates via a cellular telephone network.

8. The system of claim 1 wherein said first means is a derived channel unit and said second means is a radio transmitter, and wherein said connecting means operates to establish communication with said central facility using said derived channel unit during normal operating conditions.

9. The system of claim 8 wherein said communication is supervised by said central facility.

10. The system of claim 8 wherein said connecting means operates to establish communication with said central facility using said radio transmitter during a sensed alarm event.

11. The system of claim 8 wherein said derived channel unit includes means for determining a fault in communications with said central facility, and wherein said fault determining means operates to provide said connecting means with a fault signal.

12. The system of claim 11 wherein said connecting means causes said radio transmitter to operate responsive to said fault signal.

13. The system of claim 12 wherein said connecting means continues to operate said radio transmitter in the presence of said fault signal.

14. The system of claim 13 wherein said continued operation includes a radio transmission occurring responsive to a sensed alarm event.

15. The system of claim 13 wherein said continued operation includes a periodic radio transmission occurring responsive to a preselected timing sequence.

16. The system of claim 15 wherein said preselected timing sequence is variable in number of pulses and their frequency.

17. The system of claim 15 wherein said central facility includes means for searching for said periodic radio transmission responsive to the detection of a fault in said derived channel unit.

18. The system of claim 17 wherein said searching is accomplished by means for determining the coincidence of said periodic radio transmission and said preselected timing sequence.

19. The system of claim 12 wherein said derived channel unit includes means for resetting said connecting means upon cessation of said fault in communications with said central facility, returning said system to said normal operating conditions.

20. The system of claim 12 wherein an alarm event is detected if the central facility does not receive a signal from the radio transmitter following said detection of the fault signal.

21. The system of claim 11 wherein said fault determining means incorporates means for monitoring signals received from said central facility.

22. The system of claim 21 wherein said monitoring signals are acknowledgement signals received from said central facility following detection of an alarm event by said alarm device.

23. The system of claim 21 wherein said monitoring signals are polling signals received from said wired communicating lines at selected intervals.

24. The system of claim 11 wherein said fault determining means incorporates means for verifying operating functions of the derived channel unit.

25. The system of claim 24 wherein said derived channel unit includes memory means for performing desired memory functions, and wherein said verifying means operates to verify said memory functions.

26. The system of claim 8 wherein said radio transmitter is remotely tested.

27. The system of claim 26 wherein the periodic testing of said radio transmitter is responsive to periodic testing associated with said derived channel unit.

28. The system of claim 27 wherein said testing is performed from said central facility.

29. The system of claim 8 which further includes means for testing said alarm reporting system from said central facility.

30. The system of claim 29 wherein said derived channel unit is tested from said central facility.

31. The system of claim 29 wherein said radio transmitter is tested from said central facility.

32. The system of claim 1 wherein said central facility is fixed in location.

33. The system of claim 32 which further includes a mobile unit in communication with said alarm reporting system.

34. The system of claim 33 wherein said mobile unit is in communication with said central facility.

35. The system of claim 33 wherein said mobile unit is in communication with the second means of said alarm reporting system.

36. The system of claim 1 wherein said connecting means controls the operation of said first means and said second means at times other than an alarm event sensed by said alarm device.

37. The system of claim 36 wherein said other times are a fault detected by said alarm device.

38. The system of claim 1 wherein said alarm device is simultaneously connected with said first means and said second means.

39. The system of claim 1 wherein the wired communicating lines are wired telephone communicating lines.

40. The system of claim 39 wherein said selected number is a dialed telephone number.

41. The system of claim 1 wherein said first means establishes a direct communication between the controlling means of said alarm device and said central facility.

42. The system of claim 41 wherein said second means establishes a direct communication between the dialing means of said alarm device and said central facility.

43. A supervised, interactive alarm reporting system for providing communication between an alarm device associated with a premises and including means for controlling operations of said alarm device responsive to signals received from a plurality of sensors associated with said premises and means for dialing a selected number responsive to signals received from said controlling means, and a central facility for monitoring the alarm device at said premises, comprising:
