Door sensor
The Mount Kelvin wireless door sensor signals the system for changes in door state and is used for occupancy detection (together with the motion sensors) and welcome lights. It is battery powered and surface mountable with an included installation bracket. The battery life is 1-2 years with the included coin cell battery.
The sensor consists of two parts: the main sensor assembly and the magnet enclosure. The magnet enclosure may be replaced with another magnet (for example one drilled into a door).
