Around a year ago, following some false alarms and advice on this forum I replaced the standard Pyronix KX15DQ Quad PIR with an Optex mx40dt. This was the case for the garage and loft. For over a year, I have had no issues.
Last night however, I had the alarm blaring in the middle of the night (downstairs zone armed overnight) as the garage PIR had been activated. This caused us and specifically my children considerable distress. I want to avoid a repeat of last night please and would greatly appreciate your advice.
Upon investigation, there was no human intrusion and I couldn't see any other plausible explanations. Do you have any suggestions on how I go about troubleshooting this and ultimately resolving it?
Thanks in advance.
