The switch is equipped with two small motion sensors that react to changes of temperature against the environment. Their detection range is approximately 2 meters. Due to their character, they should be installed inside cabinets. After opening, for example, the wardrobe door, the sensor detects the human body warmer than the environment and turns on the light.
The runtime of light after the object leaves „the field of view” of the sensor is about 45 seconds.
If you do not need both sensors, you can easily disconnect one by unfastening the miniAMP connector.
