## Summary description

Busch-Jaeger 6131/31-24 is a ceiling-mounted passive infrared (PIR) presence sensor with wired connectivity.

Compact white housing (91×91×45 mm) suits lighting control and energy-saving automation in offices, corridors and residential spaces.

## Long description

Ceiling passive infrared (PIR) sensor Busch-Jaeger 6131/31-24 is a wired, ceiling-mounted presence detector for indoor use. It detects seated and walking persons in a circular pattern depending on mounting height, supports up to two-channel constant-light control, HVAC functions and integrated room temperature control, and connects to KNX for building automation. The compact white housing (91 × 91 × 45 mm) is suitable for installation in suspended ceilings or surface mounting; recommended cut-out is Ø 68 mm and compatible installation housings are suggested for reliable fit.
Advantages
The sensor provides multi-zone detection with detection diameters up to 16 m (for walking persons at 4 m mounting height) and up to 14 m for seated persons, offers four detection channels and ten freely programmable IR channels. It integrates brightness evaluation (internal sensor plus up to two external brightness weighting), two independent dimming outputs for daylight control, HVAC control for heating/cooling and ventilation, and built-in monitoring and two-stage power-off functions. The device includes a KNX bus coupler for easy integration and a small mounting depth for flexible installation.
Suitable for
Office spaces and open-plan areas for presence-based lighting control
Corridors and stairwells requiring automatic dimming and stair/exit lighting logic
Meeting rooms and residential rooms needing HVAC-linked presence control
Rooms with suspended ceilings (board thickness 9–25 mm) or surface-mounted installations

How to use
Install the sensor in a ceiling at the recommended mounting height of 2–4 m using the Ø 68 mm cut-out or appropriate surface-mount accessory. Connect the KNX bus via the bus connection terminal and supply the device with the specified 24 V DC. Program detection channels, IR channels and logic functions via the KNX interface or with the compatible IR transmitter (6010-25 / -500) to activate the programming button. Configure brightness thresholds, dimming outputs and HVAC control in the building automation system or according to the online catalogue software instructions.
Usage recommendations
For reliable detection and correct function allow the visible height of 23 mm and the specified mounting depth; use the recommended installation housings for concrete or special ceiling types and avoid installation in British Standard or VDE flush-mounted boxes. Check the current online catalogue for detailed software and configuration guidance.
