## Summary description

Steinel IR Quattro HD-2 KNX is a surface-mounted presence sensor designed for KNX building automation. The unit detects motion and presence using infrared technology, enabling automatic lighting control and energy-saving scenes. It connects to KNX systems for centralized control, suitable for offices, corridors, meeting rooms and commercial spaces where reliable presence detection and integration with KNX logic are required.

## Long description

The Steinel IR Quattro HD-2 KNX surface-mounted presence sensor integrates infrared presence and motion detection with KNX building automation for centralized control of lighting and energy management. Designed for installation on ceilings or walls in commercial and office environments, this sensor recognises both movement and presence to trigger automatic lighting scenes and ensure energy-efficient operation. The unit supports KNX communication to share status, send switching commands and participate in complex automation scenarios where reliable detection and configurable behaviour are required.
Advantages
The IR Quattro HD-2 KNX provides precise infrared-based detection with adaptive sensitivity settings and a compact surface-mounted design that simplifies retrofits. Its KNX compatibility enables seamless integration into existing building control systems for coordinated lighting, shading or HVAC actions. The sensor’s detection logic distinguishes between transient motion and sustained presence, which improves comfort and reduces false triggers while supporting energy-saving strategies.
Suitable for
Open-plan offices and individual workstations
Corridors and circulation areas in commercial buildings
Meeting rooms and conference spaces with automated lighting scenes
Retail areas and showrooms requiring presence-based control
Key specifications
Detection principle: passive infrared (PIR) presence and motion detection
Mounting: surface-mounted installation on ceilings or walls
Communication: KNX protocol for integration with building automation
Coverage: multi-zone detection pattern suitable for rooms and corridors
Adjustable sensitivity and detection parameters to reduce false triggers
Suitable for commercial and office indoor environments
How to use
Install the sensor on the ceiling or wall at the recommended position for optimal coverage, following wiring and mounting instructions provided by the manufacturer and national electrical regulations. Connect the device to the KNX bus for configuration and parameterisation via ETS software or the designated commissioning tool. Adjust sensitivity, time delay and detection zones according to room layout and expected occupancy patterns to ensure reliable presence detection and efficient automation behaviour.
Usage recommendations
Place the sensor to avoid direct sunlight or heat sources and position it to cover primary activity zones. During commissioning, test detection with typical occupant movement and fine-tune parameters to balance responsiveness and false-trigger prevention. Use KNX integration to combine presence signals with lighting scenes and energy-saving schedules for consistent automated operation.
