Abstract

A cell phone based test capability enables a tester to audibly communicate with a fire alarm control unit. A detector can be selected and tested. Test results can be audibly communicated to the tester via the cell phone. The tester can initiate the next test via the cell phone.

Claims

1. A method testing of permanently mounted stationary sensors of an alarm system comprising:

establishing a wireless communication path between an alarm system control unit and a portable wireless communications device in the audio and/or visual vicinity of one of the stationary detectors associated with the alarm system, the control unit is in a first state;

sending a command from the wireless communication device to the control unit to exit the first state and to enter a walk test mode;

identifying a stationary detector to be tested using the communication path, at the control unit, the control unit responding to a test signal from the detector by entering a predetermined state; and

sending a command from the wireless communications device to the control unit to exit from the predetermined state and to enter a normal or a non-alarm state.

2. A method as in claim 1 which includes forwarding a command, via the communication path, to the control unit to return to the first state.

3. A method as in claim 1 which includes establishing a test condition in the vicinity of the detector to be tested and responsive thereto generating the test signal.

4. A method as in claim 3 where fire alarm systems are being tested and establishing includes establishing an airborne test condition selected from smoke substitutes and/or hot air and the portable wireless communication device is a cell phone.

5. A method as in claim 3 where establishing includes placing the detector to be tested into a test state.

6. A method as in claim 3 which includes forwarding a command, via the communication path, to the control unit to return to the first state.

7. A method as in claim 1 which includes coupling audio indicia relative to the test signal via the communication path to the communications device.

8. A method as in claim 7 which includes forwarding a command, via the communication path, to the control unit to return to the first state.

9. A method as in claim 8 where forwarding the command includes forwarding a spoken command or a keyed command.

10. A method as in claim 9 which includes establishing a file of test results.

11. An apparatus comprising:

a system which monitors ambient conditions in a region, the system including a plurality of permanently mounted stationary ambient condition detectors and an interface for receiving communications from a portable wireless source of commands;

the portable wireless source of commands operable in the audio and/or visual vicinity of one of the stationary detectors to be tested, the source having at least one of a manually operable command input port, or an audio input transducer with the system responsive to a command received from the source to enter a walk test mode, to further respond to signals from a selected detector and, to emit at least an audible alarm with the system additionally responding to a command from the source to terminate the audible alarm and test state of the selected detector to allow testing of other detectors and with the system additionally responding to signals from the source to return the status into a normal or non-alarm state.

12. An apparatus as in claim 11 where the portable source comprises a wireless telephone.

13. An apparatus as in claim 12 where the wireless telephone communicates with the system interface via a public switched telephone network.

14. An apparatus as in claim 13 where the system includes speech recognition circuitry.

15. An apparatus as in claim 14 which includes circuitry and software responsive to received audible commands to select the detector.

16. An apparatus as in claim 15 which includes circuitry and software responsive to received audible commands to terminate the alarm state of the selected detector.

17. An apparatus as in claim 15 where the audible commands are at least one of tones or speech.

18. An apparatus as in claim 17 where the system interface outputs verbal information to the portable source.

19. An apparatus as in claim 18 where the system interface includes software for compiling a log of tested detectors.

20. An apparatus as in claim 19 where the detectors are selected from a class which includes at least smoke detectors, thermal detectors, motion detectors, flame detectors, gas detectors and humidity detectors and the detectors are wired to a control unit, a wireless communication path between the control unit and the wireless telephone.

21. An apparatus as in claim 11 where the system interface includes circuitry to output audio, via the source, related to the alarm state.

22. An apparatus as in claim 11 where the system interface includes circuitry to output at least one of verbal or text messages to the source.

23. An apparatus as in claim 22 where the system interface includes circuitry to receive at least one of verbal or text messages from the source.
