More quality of life, safety, and energy savings through intelligent sensor technology from Steinel. Lights on/off - automatically. Highly innovative sensors respond to movements and light conditions, turning the lights on automatically and off again after a set time. The IS 240 DUO infrared wall sensor, with a detection angle of 240°, is the optimal solution for monitoring large house fronts and outdoor edges. This sensor is equipped with two highly sensitive infrared detectors arranged at a special angle to each other, allowing it to monitor areas of up to 230 m² without interruption. When mounted on outdoor edges, it can cover a particularly large area with its wide detection angle, eliminating the need for a second sensor. The detection range can be limited if necessary using the included cover plates. Individual settings for time and twilight thresholds can be easily adjusted via a rotary control. Thanks to the spacious, clearly designed connection area, the IS 240 DUO infrared motion detector can be quickly and easily mounted on the wall or in a corner, with the appropriate corner wall bracket included. The connection cable can be mounted on the surface or recessed.
