The ceiling-installed sensor KINASGARD® / PHOTASGARD® DBWF ⁄ LF ⁄ FTF is used to detect persons at a distance of up to 10 meters, luminous intensity or brightness, relative humidity and temperature. It is used 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 of 0 - 10 V corresponding to 0...+50 °C and 0...100 % r.H. is available. Deviations due to the mounting position and location can be compensated internally using one offset regulator respectively.

For the Luminous intensity and 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 DIP switches.

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.
