Passive infrared presence detector for ceiling mounting. It features a circular detection range of 360° with a range of 8 meters (50 m²) at a mounting height of 3 meters. This device includes a 1-channel light relay (230 V) and offers automatic motion and brightness-dependent control for lighting. It is suitable for mixed light measurement of fluorescent lamps, halogen/incandescent bulbs, and LEDs.

The detector operates fully automatically with an adjustable brightness switching threshold. It has a learning function, a pulse function for stairwell lighting, and an adjustable time delay. The detection sensitivity can also be adjusted, and there is a test mode to check lamps and LEDs.

It is ready for use immediately thanks to factory presetting, with a brightness switching threshold of 300 Lux and a time delay of 10 minutes. To change the values and settings, one of the following optional remote controls is required: universal remote control theSenda B, service remote control theSenda P, or optional user remote control theSenda.
