I took over an intrusion alarm account/system and am having issues with a wired zone on a vista 128 (4 years old). Every once in a while when armed and no one in the building, a motion detector will trip and the system alarm. The motion detector is in an open, cubicle space with no facing windows, except a glass door approximately 35-40ft away.
Steps I've taken so far:
- Replaced the motion device
- Checked the cable for continuity
- Reprogrammed the zone (idk, just tried)
I typically use glass breaks instead because of reasons like this so I honestly know very little about motion; like what possible items could be setting it off. Here is the spec sheet of the motion detector.
Could anyone give me suggestions of environmental issues to look for? Could it be the panel contacts on the zone? Any suggestions are appreciated, thank you
