Detection area: rectangular. At a mounting height of 3 m: - Approaching the detector head-on, maximum 20 m x 3 m (maximum 10 m x 3 m per side). - Walking perpendicular to the detector, maximum 30 m x 3 m (maximum 15 m x 3 m per side). With integrated KNX bus coupler. Installation height of 27 mm. Equipped with 4 channels. For dimming/regulating brightness to a defined value within a designated detection area. HVAC function for controlling heating and/or cooling systems as well as ventilation systems within the designated detection area. Detector application with a 2-stage shutdown function. Detector application with integrated monitoring function. Constant light controller with up to 2 independent channels. Constant light controller with a maximum of 2 outputs for brightness-dependent dimming/regulating of two light bands in the room. Integrated object-room temperature controller. 10 freely programmable IR channels (blue and/or white) including 5 logic channels (logic gates, gate, delay, and stairwell light). Evaluation via internal brightness sensor. Weighting of up to 2 external brightness values and the internal brightness sensor is possible. The programming button can be activated with the IR remote control. Ceiling mounting on suspended ceilings with spring clips, on solid ceilings in surface-mounted housing, or on VDE flush-mounted boxes with intermediate ring for VDE flush-mounted boxes. Suitable for suspended ceilings with a panel thickness of 9 to 25 mm. Cut-out size: Ø 68 mm. Not compatible with British Standard and VDE flush-mounted boxes. Recommendation: HaloX® 100 from Kaiser with corresponding cover or IBTronic H120-68 from Spelsberg. HVAC = Heating, Ventilation, Air Conditioning.
