5. Installation
Follow these steps for proper installation of the motion detector. It is recommended that installation be carried out by a qualified electrician.
5.1. Preparation
- Ensure the main power supply to the installation area is switched off at the circuit breaker.
- Prepare a standard flush-mount wall box (53x53x23mm minimum internal dimensions) at the desired installation height (recommended 1m - 1.8m for optimal detection).
5.2. Mounting and Wiring
- Carefully remove the front cover of the motion detector to access the wiring terminals and mounting plate.
- Connect the electrical wires to the terminals as shown in the wiring diagram below. Ensure correct connections for Live (L), Neutral (N), and Switched Live (L') to the light fixture.
- Secure the main sensor unit into the flush-mount wall box using appropriate screws.
- Reattach the front cover to the sensor unit.

5.3. Detection Area
The sensor has a detection range of up to 10 meters and a 190-degree angle. The optimal installation height is between 1m and 1.8m. Consider the placement to avoid false triggers from moving objects or heat sources.

6. Operation
Once installed and powered on, the motion detector will automatically control the connected lighting based on its settings. The sensor activates the light when motion is detected within its range and the ambient light level is below the set LUX threshold. The light will then remain on for the duration set by the TIME control.
7. Settings Adjustment
The motion detector features two adjustable controls: TIME and LUX. These controls are typically located behind the front cover of the sensor unit.

Image 7.1: View of the adjustment dials for TIME and LUX settings.
- TIME (Light Duration): This dial adjusts how long the connected light remains on after motion is detected and no further motion is sensed. The settings typically range from 10 seconds to 30 minutes. There may also be an option for permanent ON or OFF. Turn the dial clockwise to increase the duration and counter-clockwise to decrease it.
- LUX (Ambient Light Sensitivity): This dial sets the ambient light threshold. The sensor will only activate the light if the surrounding natural light level is below this set value. The range is typically from 3 LUX (very dark, only activates at night) to 2,000 LUX (daylight, activates regardless of natural light). Turn the dial towards the sun symbol for higher sensitivity (activates in brighter conditions) and towards the moon symbol for lower sensitivity (activates only in darker conditions).
8. Maintenance
To ensure optimal performance and longevity of your motion detector, follow these simple maintenance guidelines:
- Cleaning: Periodically clean the surface of the sensor, especially the lens, with a soft, dry, lint-free cloth.
- Avoid Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the plastic housing or the sensor lens.
- Obstruction Check: Ensure that the sensor lens is clear of any obstructions such as dirt, spiderwebs, or vegetation that could interfere with its detection capabilities.
- Power Off for Deep Cleaning: If a more thorough cleaning is required, always disconnect the power supply before proceeding.
9. Troubleshooting
If you encounter issues with your SEBSON motion detector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. | No power supply Faulty bulb Incorrect wiring LUX setting too high TIME setting too short | Check power connection and circuit breaker. Replace bulb. Verify wiring against diagram (Section 5.2). Adjust LUX setting to a lower value (towards moon symbol). Increase TIME setting. |
| Light stays on continuously. | TIME setting on permanent ON Continuous motion in detection area Faulty sensor | Adjust TIME setting to a timed duration. Remove obstructions or reposition sensor. Contact support if problem persists. |
| Light turns on randomly without apparent motion. | Environmental factors (e.g., moving branches, small animals, heat sources) High sensitivity | Reposition sensor to avoid interference. Adjust sensitivity (if available) or reposition. |
| Detection range is too short or too long. | Incorrect installation height Obstructions Sensitivity settings | Adjust installation height (refer to Section 5.3). Clear obstructions from detection path. Check if there are sensitivity adjustments (not explicitly mentioned for this model, but common). |
