Motion sensor attachment 2.20 m standard for KNX in pure white satin finish. Sensitivity adjustment via a control knob on the device. Display of motion detection (permanent or only during walk test). A configurable function block. The function block can be configured for the applications "Guardian," "Guardian with cut-off 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, scene secondary device, 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 by local control at additional KNX motion sensors via 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 in a senior residence. The operation of motion detection can be adjusted in the applications "Guardian" or "Guardian with cut-off brightness." The device can be used in the applications "Guardian" or "Guardian with cut-off brightness" as a standalone device, main, or secondary device. Walk test function to assist in the planning and adjustment of the PIR detection area.
