Steinel IR QUATTROMICRO KNX V3 aanwezigheidsmelder, 360° PIR, inbouwmontage, wit 064129

The Steinel IR QUATTROMICRO KNX V3 is a flush-mount ceiling presence detector with a 360° passive infrared sensor, designed for KNX building automation. It detects motion and presence across a radial area of up to 6 m diameter (28 m²) and tangential up to 8 m diameter (50 m²), making it suitable for offices, corridors, and meeting rooms.

Advantages

With four independent switching channels for lighting, HVAC, presence, and additional functions, this detector enables precise control of building systems. It supports constant light control and basic light function, enhancing energy efficiency and occupant comfort. The device is powered directly from the KNX bus with a consumption below 0.5 W, eliminating the need for an external power supply.

Suitable for

• Office spaces and conference rooms
• Corridors and stairwells
• Classrooms and training facilities
• Hotels and public buildings with KNX infrastructure
