BEG BRCK LUXOMAT PD4N-KNXs-ST-UP KNX Presence Detector, Ceiling Flush-Mount, 360°, White

Managing lighting, HVAC, and presence-based automation in commercial and residential spaces often requires multiple sensors and complex wiring. The BEG BRCK LUXOMAT PD4N-KNXs-ST-UP solves this by integrating a high-precision passive infrared presence detector directly into the KNX bus system, enabling intelligent control of lighting, heating, ventilation, and scenes from a single ceiling-mounted device.

Who is it for

This presence detector is ideal for electricians, system integrators, and building automation professionals who need a reliable, flush-mounted KNX sensor for offices, meeting rooms, classrooms, corridors, and other areas where occupancy-based control is desired. It is also suitable for homeowners with KNX installations looking to enhance comfort and energy efficiency.

Main features

• 360° detection angle with a range of up to 8 m in diameter for walking persons and 4 m for seated persons at a recommended mounting height of 2.5 m.
• Four independent channels for light, HVAC, presence, and output, allowing flexible control strategies.
• Integrated light sensor with adjustable range from 10 to 2000 lux for constant light control.
• Passive infrared (PIR) sensor technology for reliable motion detection.
• KNX bus powered, consuming less than 10 mA, with no additional power supply required.
• Compact design with a visible height of only 18 mm and installation depth of 24 mm for discreet ceiling integration.
• UV-stabilised polycarbonate housing in white (similar to RAL 9010) for durability and aesthetic neutrality.
• Configurable via ETS (Engineering Tool Software) for customised parameters and scene management.

Tips

For optimal detection, install the detector at a height of 2.5 m in an open area free from obstructions. Use ETS to fine-tune sensitivity, light thresholds, and channel functions according to the specific room usage. Avoid placing near air vents or heat sources that may cause false triggers.
