## Summary description

Steinel Q HD-2 DALI2‑IPD AP is an infrared presence and twilight sensor designed for occupancy detection and daylight monitoring. It integrates motion sensing and light-level detection for automated lighting control with DALI2 compatibility (IPD), suitable for offices, corridors and public buildings. The device provides hands-free switching and energy-saving control of lighting systems where reliable presence detection and dusk/dawn response are required.

## Long description

Steinel Q HD-2 DALI2-IPD AP is an infrared presence and twilight sensor that combines occupancy detection and daylight monitoring for automated lighting control. Designed for use with DALI2-compatible systems, the sensor detects human movement and ambient light levels to enable hands-free switching, energy-efficient operation and reliable dusk/dawn responses in commercial environments such as offices, corridors and public buildings.
Advantages
The sensor provides precise infrared-based presence detection and integrated twilight measurement to maintain consistent lighting conditions and reduce energy consumption. Built for compatibility with DALI2 systems, it supports centralized lighting control and smooth integration into existing electrical infrastructures. The device's compact design and configurable detection parameters allow flexible installation and tailored performance for different room geometries and use patterns.
Suitable for
 Office open-plan areas and meeting rooms
 Corridors, stairwells and circulation spaces
 Public buildings such as schools, hospitals and municipal facilities
 Indoor spaces where combined occupancy and daylight control is required
Key specifications
 Detection technology: passive infrared (PIR) for presence sensing
 Daylight measurement: integrated light-level sensor for twilight/dawn response
 Control compatibility: designed for DALI2 lighting control systems
 Mounting: recessed or surface options suitable for ceiling or wall placement (model-dependent)
 Typical applications: commercial interiors with centralized lighting management
How to use
Install the sensor according to the local wiring and mounting guidelines and connect it to the DALI2 lighting network. Position the sensor to have an unobstructed view of the monitored area and avoid mounting near heat sources or air vents that could affect accuracy. Configure sensitivity, time delay and daylight thresholds via the compatible DALI2 commissioning tools or device settings to match occupancy patterns and ambient light conditions. After commissioning, the sensor will switch lights on when presence is detected and hold or dim lighting based on the measured daylight level and configured parameters.
Usage recommendations
For reliable performance, verify line-of-sight coverage and set daylight thresholds to reflect natural light variations in the specific installation. Use DALI2 commissioning software to fine-tune sensitivity and time delay settings for peak energy efficiency while maintaining user comfort.
