For System M. The cover is made from recycled material consisting of industrial waste. The color is black, adhering to RAL9005, with a matte finish due to the coating. The product is designed for use in IP20 for flush or surface mounting. Presence detectors for indoor use with anti-creep protection. The sensor module detects moving heat sources (e.g., people) within an adjustable detection range and activates a stair lighting duration. The sensor module features a light sensor with an adjustable brightness threshold, ensuring that the lighting is only turned on below a certain brightness level. Thanks to the presence function, the sensor module can turn off the lighting even when a person is present if there is sufficient natural light. Functions include brightness-dependent stair lighting function, electronic switching unit, relay switching unit, universal dimmer unit, 1-10 V control unit, DALI control unit, brightness-dependent stair lighting function with channel 1, brightness-independent stair lighting function with channel 2, electronic switching unit, double, relay switching unit, double, universal dimmer unit, double. Detection range of 180 degrees. Number of levels: 6. Number of zones: 46. Recommended mounting height: 2.2 m. Range: 8 m to the right/left, 12 m forward. Sensitivity is continuously adjustable. Light sensor is continuously adjustable from approximately 10 to 1000 Lux. Time is continuously adjustable from approximately 10 seconds to 30 minutes.
