## Summary description

Recessed Steinel HALLWAY KNX V3.5 presence and dusk sensor for KNX systems. Square black design with IP20 protection, intended for indoor ceiling or wall installation.

## Long description

The Steinel HALLWAY KNX V3.5 recessed presence and dusk sensor in square black is designed for integration into KNX building automation systems. Intended for indoor ceiling or wall mounting, the sensor detects motion and measures ambient light to automate lighting in corridors, stairwells and entryways. Its recessed design provides a discreet appearance while maintaining reliable detection and compatibility with KNX control logic for centralized, energy-conscious lighting management.
Advantages
The device combines presence detection and twilight sensing in a single unit, enabling automatic switching and dimming based on occupancy and current light levels. Recessed installation yields a neat visual result and reduces protrusion in narrow spaces. KNX compatibility allows seamless integration with other building systems, facilitating centralized control and programmable scenes. The IP20 protection rating is suitable for typical indoor environments such as hallways and stairwells.
Suitable for
Corridors and hallways in residential and commercial buildings
Stairwells and landings where automatic lighting is required
Entrance areas and vestibules with variable daylight
KNX-managed lighting systems requiring presence and daylight feedback
Key specifications
Sensor functions: presence (motion) detection and ambient light (dusk) sensing
Mounting type: recessed for ceiling or wall installation
Shape and finish: square, black housing
Protection class: suitable for indoor use (IP20)
Integration: designed for use within KNX building automation networks
How to use
Install the recessed sensor in the ceiling or wall cavity at a location that provides an unobstructed view of the area to be monitored. Connect the device to the KNX bus and incorporate it into the KNX configuration software to define detection zones, time delays, light thresholds and scenes. Adjust sensitivity and ambient light setpoints through the KNX parameters or local configuration options provided by the system. Verify coverage by walking through the monitored area and fine-tune settings as needed for reliable operation without unnecessary switching.
What to consider before purchase
Ensure the installation surface supports recessed mounting
Verify compatibility with your existing KNX infrastructure
Check that the detection range matches the dimensions of your hallway or corridor
Confirm that the IP20 rating is sufficient for your specific indoor environment
Usage recommendations
Place the sensor where its field of view covers the typical pedestrian paths without obstructions. For stairwells or narrow corridors, mount the unit centrally to optimize coverage. Set ambient light thresholds to prevent switching during sufficient daylight and use time delays to avoid frequent on/off cycles in areas with intermittent traffic. Ensure KNX programming includes appropriate scenes and priority rules to coordinate the sensor with other automation functions.
