## Summary description

Steinel DUALTECH COM1 DE is a combined presence and twilight sensor for wall mounting. It integrates occupancy detection and dusk sensing to control lighting automatically based on motion and ambient light levels. Suitable for indoor or sheltered outdoor applications where automatic on/off switching of lights improves energy efficiency and convenience in corridors, entrances or workspaces.

## Long description

Steinel DUALTECH COM1 DE is a wall-mounted presence and twilight sensor that combines passive infrared and microwave detection with ambient light measurement. Designed for indoor and sheltered outdoor locations, the device automatically switches lighting according to occupancy and natural light levels, helping to reduce energy consumption in corridors, entrances and workspaces. The compact housing and adjustable mounting make it suitable for retrofit or new installations where reliable, automatic lighting control is required.
Advantages
The DUALTECH COM1 DE combines two sensing technologies to improve detection reliability and reduce false triggers compared with single-technology sensors. Integrated twilight sensing prevents lights from switching on when sufficient daylight is available, contributing to energy savings. Wall-mount design and adjustable detection parameters allow flexible placement and adaptation to different room sizes and traffic patterns. The unit is intended for easy integration into standard lighting setups and offers stable, automatic operation without constant manual intervention.
Suitable for
 Corridors and stairwells in residential and commercial buildings
 Entrances, lobbies and reception areas
 Workspaces, storage rooms and utility areas
 Covered outdoor areas such as canopies or sheltered walkways
Key specifications
 Detection method: combined PIR (passive infrared) and microwave
 Function: presence (occupancy) detection and ambient light (twilight) sensing
 Mounting type: wall-mounted
 Operating environments: indoor and sheltered outdoor applications
 Adjustable sensitivity and light threshold settings for tailored operation
 Automatic on/off switching of connected lighting based on motion and light level
How to use
Install the sensor at a recommended height on a wall in a location with a clear view of the area to be monitored, following safety and mounting instructions from the manufacturer. Configure the sensitivity and twilight threshold according to the ambient conditions and expected traffic to ensure reliable detection and prevent unwanted switching. Connect the sensor into the lighting circuit using appropriate wiring practices; once powered, the device will automatically turn lights on when presence is detected and the light level is below the set threshold, and switch lights off after the absence timeout expires.
Usage recommendations
Position the unit where movement crosses the detection zone rather than directly toward it to improve trigger reliability. For areas with intermittent daylight, set a conservative light threshold to avoid unnecessary switching. Regularly check alignment and cleanliness of the sensor window to maintain detection performance.
