Presence detector Steinel IR Quattro HD KNX 058470 – passive infrared KNX ceiling sensor

The Steinel IR Quattro HD KNX is a passive infrared ceiling presence detector designed for integration with KNX building automation systems. Intended for ceiling mounting in offices and commercial spaces, the sensor detects motion and presence to control lighting and HVAC systems. The detector supports reliable occupancy detection with a wide coverage pattern and configurable parameters via the KNX bus, helping to optimise energy use and maintain comfort in populated areas.

Advantages

The presence detector combines passive infrared sensing with KNX connectivity to provide accurate occupancy information without requiring line-of-sight between sensor and person. Ceiling mounting offers a broad detection area and unobtrusive installation. Configurable detection sensitivity, time delays and presence thresholds via KNX enable adaptation to different room sizes and usage patterns. The device is designed for consistent detection performance in typical indoor environments and reduces manual intervention by automating lighting and climate control actions.

Suitable for

• Open-plan offices and meeting rooms
• Corridors, lobbies and reception areas
• Classrooms and training rooms
• Retail premises and commercial spaces

Key specifications

• Detection principle: passive infrared (PIR)
• Mounting: ceiling-mounted installation
• Integration: KNX compatible for bus-based control and configuration
• Coverage: wide-area detection pattern suitable for medium to large rooms
• Adjustable parameters: sensitivity, presence time delay and threshold via KNX
• Intended use: indoor environments for presence and motion detection

How to use

Install the detector in a suitable ceiling position to ensure optimal coverage of the target area. Connect the device to the KNX bus and use the KNX commissioning tools to configure detection sensitivity, presence detection thresholds and automatic output behavior for lighting and HVAC control. Verify detection coverage by walking typical occupant paths and adjust mounting location or sensitivity settings if necessary. Regularly check KNX parameter settings when room layout or usage changes.

Recommendations

Place the sensor centrally on the ceiling for the most uniform coverage and avoid mounting near large heat sources or direct air vents. When configuring via KNX, set time delays and sensitivity according to typical occupancy patterns to avoid frequent switching and to optimise energy savings while maintaining comfort.
