Magnetic Contact Sensor

The MC-31 is an easy-to-install, battery-powered sensor that monitors the status of a window or door. When mounted on the inside of a window or door jamb, the MC-31 helps users to capture energy savings in lighting and HVAC control systems by providing passive occupancy detection. It wirelessly transmits the open or closed status of a window or door to trigger lighting controls or HVAC setback temperature control devices.
