AC-3PETPIR - Set of 3. The YALE Pet Friendly PIR Motion Detector is compatible with the Yale Sync and Yale Intruder alarm ranges. When set, the alarm will be activated when larger motion (27kg and above) is detected, and will work up to 200m away from the control panel, making it the ideal pet-friendly option when protecting your home. It is perfect for homes with one small pet - if there are larger or multiple pets in the home, the Yale Door & Window Contact will be better suited to your needs (please see related products). Batteries and fixings are included and it comes complete with a 2 year guarantee.. When the alarm is set, the infrared sensor will pick up movement and activate the siren. Ideally placed in the corner of any room. Will not be triggered by a single pet that weighs below 27kg (not suitable for multiple pets). For use in extra rooms that need protection, such as lounge, bedroom or extension
