Motion sensor attachment 1.10 m standard for KNX in glossy cream white. Sensitivity adjustment via a dial on the device. Display of motion detection (permanent or only in test mode). One configurable function block. Configurable function block for the applications "Guardian," "Guardian with cutoff brightness," or "Detector." The function block has two output communication objects available, through which switching and control commands are sent to the KNX bus. Configurable functions: switching, stairwell function, dimmer, scene auxiliary, temperature sensor, brightness sensor, operating mode switching, forced switching. Switching of operating mode (OFF / AUTO / ON) during operation via local control or through communication object via local control at additional KNX motion sensors using touch sensor for KNX or visualization. The function block can determine the duration after the last motion in brightness-independent operation and send it to the KNX bus via a communication object. This function allows for simple monitoring of people’s movements in assisted living or senior residences. The operation of motion detection is adjustable in the applications "Guardian" or "Guardian with cutoff brightness." The device can be used in the applications "Guardian" or "Guardian with cutoff brightness" as a standalone device, main, or auxiliary unit. Test mode function to assist in the planning and adjustment of the PIR detection area.
