Motion detector attachment 2.20 m standard for KNX in pure white glossy finish. Sensitivity adjustment via a control knob on the device. Display of motion detection (permanent or only during walk test). 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 the switching and control commands are sent to the KNX bus. Configurable functions: Switching, stairwell function, dimmer value transmitter, scene auxiliary, temperature value transmitter, brightness value transmitter, operating mode switching, forced switching. Switching of operating mode (OFF / AUTO / ON) during operation via local control or through communication object by local control at additional KNX motion detectors via touch sensor for KNX or visualization. The function block can determine the time span after the last motion in brightness-independent operation and send it via a communication object to the KNX bus. This function allows for simple monitoring of people’s movements in assisted living or senior residences. The operation of motion detection can be adjusted 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, as a main or auxiliary unit. Walk test function to assist in the planning and adjustment of the PIR detection area.
