Steinel 033774 HF 3360-E KNX motion detector

It simply detects everything. Very quickly and, if required, over 2 floors. High frequency technology is the perfect alternative, especially in areas that can be a problem for temperature-dependent infrared sensors. The HF 3360 is therefore ideal if you want to automate the lighting in winding basement corridors, stairwells and parking garages. It detects the smallest movements safely and precisely and thus ensures perfect automatic lighting control even in the stairwell over 2 floors. The HF 3360 is also ideal for all entrance areas, because the light is switched on as soon as the sensor detects the door opening. Available as a surface-mounted or flush-mounted version and of course compatible with the common interfaces.
