## Summary description

Steinel IR Quattro ST079345 is a presence and twilight sensor for ceiling or wall under-plaster installation. It provides infrared detection up to 8 m range and twilight sensing for automatic light control. Designed with COM1 interface, square white finish and IP20 protection, it suits indoor applications such as corridors, stairwells and utility rooms for energy-efficient lighting automation.

## Long description

The Steinel IR Quattro presence and twilight sensor is designed for under-plaster installation in ceilings or walls to enable automatic lighting control in indoor spaces. The device integrates passive infrared presence detection with a twilight sensor to switch lights based on motion and ambient light levels. With an 8 m detection range and a compact square white design, this IP20-rated sensor is intended for corridors, stairwells, utility rooms and similar interior areas requiring hands-free, energy-conscious lighting management. The sensor includes a COM1 interface for simple integration with compatible control systems.
Advantages
This presence and twilight sensor delivers reliable motion detection up to 8 m using infrared technology, combined with adjustable twilight sensitivity to prevent unnecessary switching when ambient light is sufficient. The under-plaster mounting provides a discreet, low-profile appearance suitable for visible ceilings and walls. IP20 protection matches typical indoor requirements, and the COM1 interface allows straightforward connection to building lighting controls. The square white finish offers a neutral aesthetic that blends with standard interior decors.
Suitable for
Corridors and hallways in commercial and residential buildings
Stairwells and landings where automatic lighting enhances safety
Utility rooms, storage areas and service spaces with intermittent occupancy
Entrance foyers and small lobbies requiring energy-efficient light control
Key specifications
Detection technology: passive infrared (PIR) presence detection
Detection range: up to 8 metres
Light sensor: twilight/ambient light detection for automatic switching
Mounting type: under-plaster installation for ceiling or wall
Protection rating: IP20 (indoor use)
Shape and color: square form factor in white finish

How to use
Install the sensor recessed into a suitable ceiling or wall cavity following local electrical regulations and the device installation instructions. Position the unit so the detection zone covers the main traffic path or the area to be monitored, and avoid placing it opposite heat sources or air vents that could affect infrared sensing. Connect the COM1 interface to the lighting control circuit or compatible controller, set the twilight threshold to the desired ambient light level, and adjust time delay settings as required for the application. After installation, verify the detection coverage and adjust orientation or sensitivity if necessary.
Usage recommendations
For optimal performance, mount the sensor at the manufacturer’s recommended height and ensure the field of view is unobstructed. Use the twilight setting to reduce unnecessary switching during daytime or where daylight is present, and configure time delays to match traffic patterns to balance convenience and energy savings.
