Good to know

The theLuxa 103 S360-100-12 DE-UP WH is a presence detector, not a motion detector: it responds to the presence of people even when they are sitting still, making it perfect for offices where employees work at desks. Installation requires a standard flush-mount box in a suspended ceiling; the detector is not suitable for solid ceilings without an adapter. The device is designed for 230 V AC mains connection and must be installed by a qualified electrician. For optimal performance, avoid placing it near heat sources or air vents that could cause false triggers. The IP20 rating means it is intended for dry indoor environments only.
