The Yale Motion Detector is wireless and easy to pair with your Yale Intruder/ Sync Alarm System, allowing you to extend your system to tailor it to your individual needs. This Pet friendly accessory will activate the alarm when larger motion (27kg and above) is detected. Ideal for homes with one small pet (less than 27kg), it will also work up to 200m away from the control panel. Please note that when used with larger pets there is an increased possibility of false alarms. In these scenarios use a Door/Window Contact to protect the area instead.
