The sensor can detect motion through less insulated walls and doors. We recommend changing DIP Switch 1 & 2 to a narrower motion detection range. In most cases, Very Near is suitable. Move switches 1 & 2 to OFF (away from the printed numbers) to change the setting to Very Near.
If that does not work, check what DIP switches 9 & 10 (Time Until Off) are. If both are OFF, the sensor is disabled. Please select 30 seconds, 10 minutes, or 30 minutes for the light to turn off automatically.
Please note the total duration the light stays on for includes Time Until Dim plus Time Until Off.
