Abstract

The present invention provides a method and system of walk through testing a fire alarm system without disrupting the building occupants. A communications channel is setup between a control panel and a communicator carried by a human tester. The tester triggers an alarm or trouble condition in a device. The control panel detects the address of the device and automatically returns to the communicator, over the communications channel, the location of the device.

Claims

1. A method of walk test in an alarm system, comprising the steps of:

setting up a communications channel between a control panel and a communicator carried by a human tester;

triggering a test condition in a device, by the tester at the device;

at the control panel, detecting the triggered test condition; and

returning to the communicator over the communications channel an indication of a location of the device.

2. The method of claim 1, the communicator comprising one of:

a personal digital assistant (PDA);

a Bluetooth-compatible communication device, a WiFi-compatible communication device, and a wireless networking device.

3. The method of claim 1, further comprising:

generating a report listing at least untested devices.

4. The method of claim 3 wherein the report is printed on paper.

5. The method of claim 3 wherein the report is communicated to the communicator.

6. The method of claim 5 wherein at least a portion of the report is displayed on the communicator.

7. The method of claim 1, the device comprising any of a sensor and a notification appliance device.

8. The method of claim 1, wherein the indication is a direct identification of the location of the device.

9. The method of claim 1, wherein the location indication is returned by:

converting a control panel label to a voice stream or textual message; and

transmitting the voice stream or textual message to the communicator over the communications channel.

10. The method of claim 1, further comprising:

the tester transmitting over the communications channel via the communicator a response to the location indication; and

storing the response in a storage device, and associating the response with the device tested.

11. The method of claim 10, wherein the response comprises at least one of:

a voice stream and a textual message.

12. The method of claim 10, wherein the storage device is a computer.

13. The method of claim 1, wherein the test condition is an alarm condition.

14. The method of claim 1, wherein the test condition is a trouble condition.

15. The method of claim 1, wherein the step of returning the indication of the location of the device further includes returning an address of the device to the tester.

16. An alarm system for walk test, comprising:

an alarm device adapted to be triggered by a human tester at the device to activate a test condition;

a control panel that detects the triggered test condition;

a communications channel between the control panel and a communicator carried by the tester;

an identifier of the device in the test condition being detected by the control panel, and an indication of a location of the device being returned to the communicator over the communications channel.

17. The alarm system of claim 16, the communicator comprising one of:

a personal digital assistant (PDA);

a Bluetooth-compatible communication device, a WiFi-compatible communication device, and a wireless networking device.

18. The alarm system of claim 16, further comprising:

a report generator which generates a report listing at least untested devices, there being plural alarm devices in the system.

19. The alarm system of claim 18 wherein the report is printed on paper.

20. The alarm system of claim 18 wherein the report is communicated to the communicator.

21. The alarm system of claim 20 wherein at least a portion of the report is displayed on the communicator.

22. The alarm system of claim 16, the device comprising any of a sensor and a notification appliance device.

23. The alarm system of claim 16, wherein the indication is a direct identification of the location of the device.

24. The alarm system of claim 16, wherein a direct identification is returned by:

a voice stream or textual message converted from a control panel label; and

a transmitter for transmitting the voice stream or textual message to the communciator over the communications channel.

25. The alarm system of claim 16, wherein the test condition is an alarm condition.

26. The alarm system of claim 16, wherein the test condition is a trouble condition.

27. The alarm system of claim 16, wherein the indication of the location of the device further comprises an address of the device.

28. The alarm system of claim 16, further comprising a storage device for storing a response transmitted by the tester over the communications channel, and for associating the response with the device tested.

29. The alarm system of claim 28, wherein the response comprises at least one of:

a voice stream, and a textual message.

30. The alarm system of claim 28, wherein the storage device is a computer.

31. An alarm system for walk test, comprising:

communications means for communicating between a control panel and a communicator carried by a human tester;

means for triggering a test condition in a device, by the tester at the device;

means, at the control panel, for detecting the triggered test condition; and

means for returning to the communicator over the communications means an indication of a location of the device.

32. The alarm system of claim 31, further comprising:

means for generating a report listing at least untested devices.

33. The alarm system of claim 32, further comprising:

means for displaying the report.
