STEINEL IS 345 MX-E KNX V3AP Motion Detector, White 058296

The IS 345 MX-E KNX V3AP brings KNX-native presence and motion detection to large indoor and outdoor areas, with a 240° PIR coverage pattern and four independent channels for lighting, HVAC, presence, and temperature. Unlike conventional detectors, it integrates directly into KNX bus systems without additional gateways, enabling constant light control, scene logic, and multi-sensor automation from a single device.

Highlights

• 240° passive infrared detection with up to 20 m tangential reach
• Four KNX channels: light, HVAC, presence, temperature
• Integrated temperature sensor for climate control
• IP54-rated for outdoor and indoor use
• Powered directly from KNX bus (21–30 V DC)

In daily use

Mount the detector at 2.00–4.00 m height on a wall or corner for optimal coverage. Through KNX, adjust twilight threshold from 2–1000 lux and switch-off delay from 30 seconds to 15 minutes. The 11 detection levels and 1416 switching zones provide fine-grained presence mapping, making it suitable for corridors, warehouses, loading ramps, and underground garages.
