Abstract

Mis-wired addressable loops are determined by enabling all loops and identifying all devices communicating on all loops. A list of all identified devices is recorded. One at a time, each loop is disconnected, a list of devices that are disabled is determined and recorded for the disconnected loop, and the loop is reconnected. When all of the loops have been processed, the lists of disabled devices are compared and those devices that are wired improperly are determined.

Claims (26)

1. A method for determining mis-wired addressable loops, comprising the steps of:

enabling all loops;

identifying all devices that are communicating on all loops;

recording a list of all identified devices;

for each loop

disconnecting the loop,

determining and recording a list of devices that are disabled for the disconnected loop, and

reconnecting the disconnected loop; and

comparing the lists of disabled devices and determining any devices that are wired improperly.

2. The method of claim 1 , wherein the steps of claim 1 are executed manually.

3. The method of claim 1 , wherein the steps of claim 1 are executed automatically.

4. The method of claim 3 , further comprising the step of:

notifying service personnel of a detected wiring fault.

5. The method of claim 4 , wherein the step of notifying includes providing a location indication of the wiring fault.

6. The method of claim 1 , wherein the loops are part of a fire alarm system.

7. A computer readable medium comprising a readable memory device containing program instructions for determining mis-wired addressable loops, the computer readable medium comprising:

computer readable code for enabling all loops;

computer readable code for identifying all devices tat are communicating on all loops;

computer readable code for recording a list of all identified devices;

computer readable code for performing, for each loop, the steps of disconnecting the loop,

determining and recording a list of devices that are disabled forte disconnected loop, and

reconnecting the disconnected loop; and

computer readable code for comparing the lists of disabled devices and determining any devices that are wired improperly.

8. The computer readable medium of claim 7 , further comprising: computer readable code for notifying service personnel of a detected wiring fault.

9. The computer readable medium of claim 7 , futher comprising: computer readable code for providing a location indication of a detected wiring fault.

10. The computer readable medium of claim 7 , wherein the loops are part of a fire alarm system.
