The ceiling-built-in motion sensor KINASGARD® DBWF-C detects the presence of persons and motions and has a switching output (normally open contact). The motion detector is used for the observation and recognition of conditions and for the motion-dependent control of room functions, e.g. for lowering temperatures in unused rooms. The ceiling motion detector is installed in suspended ceilings in corridors and offices as well as in residential rooms and business facilities. The measuring transducer is accommodated in a separate enclosure apart from the sensor. The sensor detects motions over an aperture angle of 110° and a perimeter of 360°. Because of the patented lens system with 20 individual lenses, only very small dark areas are resulting, which even at a distance of 10 m are only a few centimeters wide, safely detecting also small motions.
