Good to know

The sensor is designed for indoor use only and should be mounted directly on the glass surface for optimal detection. For larger panes, multiple sensors may be required. The included 2-meter cable allows flexible wiring to the alarm control panel. The IP30 rating means it is not suitable for damp or dusty environments.
