This motion sensor is suitable for mounting in system ceilings (recessed) and for mounting on concrete ceilings and walls (surface mounted). The motion detector is equipped with an infrared sensor that detects motion within a radius of 8 meters. The 360° detection angle ensures that motion is detected from any angle. As soon as movement is detected, the light is temporarily switched on. Install the sensor as you wish: the sensor can be mounted on hard ceilings, including concrete. You can also integrate the sensor into a ceiling system. Furthermore, you can set the response time from 10 seconds to 7 minutes. You can connect dozens of lamps to one sensor with a maximum load of 1000W (LED) and 2000W (halogen). If new motion is detected within the set time range for automatic switch-off, the time settings are automatically restarted by the built-in time delay ability.
