The motion and light sensor KINASGARD® / PHOTASGARD® RBWF ⁄ LF is a combined instrument and detects movements as well as the light intensity by means of a diffusor and the presence of persons. It is also used to recognise conditions. The RBWF ⁄ LF issues a standard signal of 0 - 10 V or 4...20 mA for light intensity, and has a switching (changeover contact) output for detecting motion.The multisensor is used in building automation, in corridors, at workplaces, in industrial halls, in offices and business facilities for the control of lighting as needed, e.g. to control sunshade equipment, for daylight-dependent constant light control, for activating Venetian blinds or luminaires, for automatic energy conservation, and to avoid unnecessary heating-up or cooling of unoccupied rooms.
