The in-ceiling sensor
KINASGARD
®
DBWF ⁄ LF ⁄ FTF
is used to detect persons within a distance of up to 10 meters and to measure luminous
intensity or brightness, relative humidity and temperature. It has been designed for installation in suspended ceilings.
The sensor detects
motion
over an aperture angle of 110° and a perimeter of 360°. The patented lens system with 20 individual lenses results in
only very small dark areas that are only a few centimetres wide even at a distance of 10 m, thereby reliably detecting small movements. If motion is
detected, the potential-free relay output is switched. The hold time of the output, measured from the moment of the last detected movement, can
be preset internally in the device via potentiometer within a range of 4 seconds to approx. 17 minutes.
For the
temperature and humidity
, an analogue output 0 - 10 V corresponding to 0...+50 °C or 0...100 % r. H. is available. Deviations due to the
mounting position and location can be compensated internally using one offset regulator respectively.
For
luminous intensity or brightness
of 0...1000 lux or 0...5000 lux (selectable via DIP switches), an analogue output 0 - 10 V is also available. It is
also possible to activate the motion output depending on brightness with the help of a jumper.
Fields of application for the DBWF ⁄ LF ⁄ FTF include residential room monitoring, automatic switching of lights, control technology, alarm technology,
and motion-dependent control of room functions, e. g. for lowering the temperature in unused rooms.
