Presence detector Steinel IR QU HD DALIPLUS AP 035273 IP54 180° motion sensor

Steinel IR QU HD DALIPLUS AP 035273 is a ceiling- or wall-mounted presence detector engineered for automated lighting control in commercial and residential interiors. With IP54 protection and a 180° detection angle, the sensor combines motion and presence detection with DALIplus compatibility to integrate into DALI-based lighting systems. The compact design and adjustable mounting options allow installation in corridors, offices, meeting rooms and utility areas where reliable occupancy detection and energy-efficient lighting control are required.

Advantages

The device offers combined motion and presence detection to reduce false switching and to maintain lighting while a space is occupied. IP54-rated protection against dust and splashes makes it suitable for indoor environments with occasional moisture or dust exposure. The 180° detection angle provides wide coverage from wall or ceiling mounting, and DALIplus integration enables centralized control and communication with compatible luminaires and control systems.

Suitable for

• Corridors and stairwells
• Offices and meeting rooms
• Toilets, washrooms and utility rooms
• Small commercial spaces and retail areas

Key specifications

• Detection angle: 180°
• Protection rating: IP54
• Mounting: ceiling or wall
• Detection modes: motion and presence detection
• Interface: DALIplus for lighting control integration
• Designed for indoor use in commercial and residential buildings

How to use

Mount the presence detector on a ceiling or wall at the recommended height and orientation to achieve optimal 180° coverage of the monitored area. Connect the sensor to the DALIplus lighting network according to the system wiring and installation guidelines, and configure detection sensitivity, hold time and daylight linking through the control interface or local settings. Verify coverage by walking through the detection zone and adjust aim or mounting position if necessary to avoid blind spots and minimize unintended triggers from adjacent rooms or external movements.

Recommendations

Locate the detector away from direct airflow from HVAC outlets and heat-emitting equipment to prevent false presence readings, and use appropriate mounting accessories to ensure stable installation. For reliable DALIplus operation, follow manufacturer wiring and grounding practices and perform on-site testing after commissioning.
