Presence sensor Steinel IR Quattro DualTech US COM2 by Steinel (model ST008000)

The Presence sensor Steinel IR Quattro DualTech US COM2 is a wall- or ceiling-mounted occupancy detector that combines passive infrared and microwave motion detection to identify people in a monitored area. Designed by Steinel for automated control of lighting and building systems, the sensor detects presence reliably in commercial and residential environments and switches outputs when movement or heat signatures are recognized. The compact housing and adjustable lens arrangement allow flexible installation in corridors, offices, stairwells and other indoor spaces where automatic switching and energy-efficient operation are required.

Advantages

The DualTech design reduces false triggers by requiring corroborating signals from both infrared and microwave sensors, improving detection accuracy in mixed environmental conditions. Adjustable sensitivity and time delay settings provide control over activation behavior, while the detection pattern covers a broad area suitable for mounting on walls or ceilings. Built to Steinel quality standards, the unit supports integration with lighting circuits and building automation for reliable, long-term operation.

Suitable for

• Corridors and stairwells in commercial buildings
• Offices and meeting rooms with intermittent occupancy
• Residential halls, entryways and utility rooms
• Energy-saving lighting control in multi-room facilities

Key specifications

• Detection technology: combined passive infrared (PIR) and microwave (DualTech)
• Mounting: wall or ceiling installation
• Coverage: multi-lens detection area suitable for typical indoor room sizes (adjustable pattern orientation)
• Adjustable settings: sensitivity and time delay for switch-off
• Output: relay/switching contact for controlling lighting or building systems
• Design: compact housing with integrated lens array for presence detection

How to use

Install the sensor on a suitable wall or ceiling surface at the recommended height and angle to align the lens pattern with the area to be monitored. Connect the device to the lighting or building control circuit following local electrical regulations and wiring diagrams supplied by the manufacturer. Configure sensitivity and time delay parameters to match the expected occupancy behavior: lower sensitivity or shorter delays in high-traffic areas, higher sensitivity or longer delays where occasional presence should be maintained. Test the detection zone after installation and adjust the orientation and settings until the required coverage and switching behavior are achieved.

Usage recommendations

Avoid mounting the sensor near large heat sources, ventilation outlets or reflective surfaces that can cause false triggers. For energy-efficient operation, combine presence detection with daylight harvesting or time scheduling in the lighting control system. Perform periodic checks of sensor alignment and settings to ensure consistent performance in changing usage patterns.
