This Door and Window Wandering Alert Kit features a pager and a door/window sensor. The sensor has a wide field coverage of 120 metres and sends an alert to the pager when triggered. The pager can be securely worn on a belt clip or lanyard and will emit a beep and vibrating alert. Users can choose between high or low beep tones, and the pager can also be set to vibrate only. The kit includes batteries to power both the pager (2xAA) and sensor (1x9v), and up to ten sensors can be connected to a single pager unit.
