Presence detector standard for KNX pure white presence detector for presence monitoring (operating mode: presence detector), for motion detection (operating mode: ceiling monitor) or for monitoring via message telegrams (operating mode: detector) indoors. Features: Flush-mounted device with integrated KNX bus connection. Programming LED button can be operated visibly after removing the decorative ring when installed. PIR sensors: three sensors (crossed beams), integrated brightness sensor. Adjuster for manual correction of sensitivity. Sensitivity configurable. Sensitivity adjuster on the device can be deactivated via software. Display of motion detection (permanent or only in the walk test). One function block can be configured. Display of motion detection (permanent or only in the walk test). Adjustable operating mode: ceiling monitor, presence detector, detector. Single device, main unit, extension unit can be set. Operating mode for single device or main unit: automatic, semi-automatic (manual ON, automatic OFF or automatic ON, manual OFF). Two outputs (for function: ceiling monitor, presence detector). Output (for function: ceiling monitor, presence detector): switching, staircase function, switching with forced position, dimming value transmitter, light scene extension, temperature value transmitter, brightness value transmitter, temperature operating mode. Twilight level adjustable via external communication object or via teach-in. Additional transmission delay via external communication object. Adaptive follow-up time (self-learning additional transmission delay). Short-term presence function. Feedback of the twilight level. Locking function. Manual operation via touch sensor (separate communication object). Switch-off brightness (for presence detector) via teach-in. Measurement of the time period after the last movement. Notes: The presence detector is not suitable for alarm messages in VdS-compliant alarm systems. Ceiling mounting on solid ceilings in device box or surface-mounted housing.
