I recently bought a new wireless house alarm. In addition to the standard kit I spent £60 on two "pet friendly" PIRs. I installed and commissioned the alarm over the last couple of evening and it went LIVE last night.
03:25 the alarm siren blares out. Guess what. Our cat triggered the "pet friendly" PIR in the lounge.
I've installed as per the instructions at a height of 2.3m. According to the literature, the signature of a pet less than 25kg should not invoke an alarm.
Any ideas folks or are PF PIRs a pipedream?
