The IR LuxSolo presence detectors can be used both in small premises such as offices, hotel or conference rooms and larger premises such as public buildings. The multiple lens system with 81 zones and 324 switch elements can detect even the smallest movements and the resulting change in status. Depending on the application and mounting height, a radius of between 1.8 and 14m can becovered. In optimal, application-tailored, conditions energysavings of up to 40% are possible. The easy integration into an already existing KNX building management system provides a particular advantage. As with all KNX devices, the sensor receives the physical address of the device as well as its group address via ETS.
