Tonight at 9:18pm, one of our PIRs reported a tamper and then ended tamper almost immediately after. My wife was home at the time, so we know no one went near that sensor. I tested the battery and it is still at 100% under load. Any ideas as to why it reported a tamper?
If it is a 2GIG PIR1, check to make sure the back cover is snapped together all the way. Sometimes these can be screwed to the back-plate without being all the way shut if the top latches are worn or broken. It might be good to open it up and take a look at the tamper switch to make sure it isn’t broken or loose.
