KINASGARD® DBWF-LF-FTF-W

The presence detector or recessed ceiling sensor KINASGARD® / PHOTASGARD® DBWF/LF/FTF is used to detect people at a distance of up to 10 meters, illuminance or brightness, relative humidity and temperature. It is used for installation in false ceilings.

The sensor detects movements with an aperture angle of 110° and 360° circumference. The patented lens system with 20 individual lenses creates very small dark areas that are only a few centimetres wide even at a distance of 10 m and reliably detect small movements. If movement is detected, the potential-free relay output is switched. The hold time of the output, measured from the time of the last detected movement, can be set internally via a potentiometer from 4 seconds to approx. 17 minutes.

For Temperature and humidity each has an analog output 0-10 V corresponding to 0...+50 °C or 0...100 % RH. Deviations caused by the installation position and location can be compensated for internally by an offset controller.

For Illuminance or brightness of 0...1000 lux or 0...5000 lux (selectable via DIP switch), a 0-10 V analog output is also available. It is also possible to activate the motion output depending on the brightness using a DIP switch.

Areas of application for the DBWF/LF/FTF include living room monitoring, automatic light switching, control and alarm technology as well as motion-dependent control of room functions, e.g. for lowering the temperature in unused rooms.
