Presence sensor Steinel IR Quattro SLIM XS DALI-2 square — infrared multi-sensor for lighting control

The Steinel IR Quattro SLIM XS DALI-2 square is an infrared presence sensor designed for automated lighting control in commercial and office environments. Using multi-zone infrared detection, the sensor monitors occupancy and presence to switch DALI-2 compatible lighting systems on or off and to adapt light levels according to detected activity. The low-profile square housing is intended for ceiling or recessed mounting and integrates with building lighting systems to reduce manual switching and support energy-efficient operation.

Advantages

The infrared multi-sensor provides reliable presence detection across several zones and distinguishes between motion and static presence to improve switching accuracy. Compatibility with DALI-2 ensures interoperability with modern lighting control systems and allows centralized management. The slim square design supports discreet installation in suspended or plaster ceilings while offering a broad detection area. Built for commercial use, the sensor helps reduce energy consumption and simplifies lighting automation without requiring visible control elements.

Suitable for

• Open-plan offices and workspaces
• Meeting and conference rooms
• Corridors and circulation areas
• Retail floors and customer areas
• Ceiling or recessed installations in commercial buildings

Key specifications

• Detection technology: infrared multi-zone presence/motion detection
• Form factor: slim square housing suitable for ceiling or recessed mounting
• Control protocol: DALI-2 compatible for lighting system integration
• Mounting type: ceiling or recess-mounted installation
• Application environment: commercial and office interiors

How to use

Install the IR Quattro SLIM XS DALI-2 in the ceiling or recess according to mounting instructions and connect to the building DALI-2 lighting bus. Configure detection zones and sensitivity via the system controller or commissioning tool to match room layout and expected occupancy patterns. Once connected and commissioned, the sensor will automatically detect presence and motion and send control signals to the DALI-2 lighting system to switch lights on, dim, or turn them off based on the programmed logic.

Usage recommendations

For reliable operation, position the sensor centrally relative to the area to be monitored and avoid installing near heat sources or strongly reflective surfaces that could affect infrared detection. Adjust sensitivity and hold-off times during commissioning to prevent false switching in rooms with low or intermittent movement. Use the sensor as part of a DALI-2 lighting scheme to enable centralized scheduling, daylight linking, and energy reporting.
