IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION AND KEEP THIS MANUAL IN A KNOWN PLACE TO BE ABLE TO READJUST THE PRODUCT IF NECESSARY.
| Function | Operation | Setting |
|---|---|---|
| Time delay before extinction | Allows adjustment of the lighting duration before complete extinction of the luminaire. | Micro-switch for time delay adjustment (30s to 180s). |
| Light sensor | Allows activation or deactivation of the twilight sensor. | Micro-switch for light sensor activation/deactivation. |
| IR Sensor | Allows activation or deactivation of the motion sensor. | Micro-switch for IR sensor activation/deactivation. |

With sufficient natural light, the luminaires do not turn on when presence is detected.
Illustration of a room with lights off, implying sufficient natural light.
If the natural light is insufficient, the sensor automatically turns on the luminaires when presence is detected.

After the hold time, the luminaires automatically turn off when no movement is detected.

3. Function and Operation (Detailed)
When a person moves in front of an infrared detector, two types of movements can be observed: radial movement and tangential movement.
Radial Movement: This type of movement occurs when a person approaches or moves away directly from the detector, i.e., facing the detector.
Tangential Movement: Conversely, tangential movement refers to movement where the person moves perpendicularly to the detector's line of sight, without significantly changing their distance from it. In other words, the person follows a trajectory parallel to the detector's surface.
Radial movement primarily changes the distance between the object and the detector, while tangential movement occurs without major changes in this distance, but with a variation in the detection angle.
4. Warning
Infrared light detectors are designed to react to temperature variations. Therefore, they cannot see through materials.
If the ambient temperature changes abruptly (Example: luminaire too close to an air conditioning unit), this can cause false triggers.
This technology requires different detection sensitivities depending on the type of person's movement. The data is based on a movement speed of approximately 5 km/h.
The light sensor reads the ambient light level around it, meaning it captures the light it receives. Caution: The sensor's measurement is therefore considerably affected by its environment:
- Installation height
- Distance from artificial lighting
- Light reflection
- Floor and wall coverings
- Surface colors
Weather also influences this measurement. For example, cloudy weather will provide different brightness than clear weather.
