Features
The devices are presence and motion detectors with integrated brightness sensor. The devices communi-
cate via KNX. All are designed for ceiling mounting.
Usage
The main application of the equipment is the detection of the presence of persons in the area and/or the
measuring of the current brightness under the device depending on sensor equipping.
Presence / motion detector
The sensor recognizes the presence of a person or that nobody is in the detection range.
Brightness measuring (Contrast measurement of brightness)
All devices have a integrated brightness sensor. The measured value can be used on KNX and internally.
In case of a indirect detection the value has to be calibrated by a correction factor to adapt it to different
installation situations. The measuring range is between 20 and 1000 lux.
