The package includes the infrared motion sensor and mounting accessories (screws and wall plugs).
5.2 Mounting Steps
- Choose Location: Select a suitable ceiling location for mounting. Consider the desired detection area and avoid placing it near heat sources or direct sunlight, which can cause false triggers.
- Open Sensor: Gently twist or unclip the sensor housing to access the mounting holes and wiring terminals. Refer to the 'OPEN' arrow on the device.
- Mark and Drill: Use the sensor's base as a template to mark the drilling points on the ceiling. Drill holes of appropriate size for the provided wall plugs.
- Insert Wall Plugs: Insert the wall plugs into the drilled holes.
- Wiring: Connect the electrical wires to the terminal block inside the sensor. Ensure correct polarity and secure connections. Typically, this involves Live (L), Neutral (N), and Load (L'). Consult a qualified electrician if unsure.
- Secure Sensor: Mount the sensor base to the ceiling using the provided screws.
- Close Housing: Reattach the sensor housing, ensuring it is securely closed and sealed, especially for outdoor use.

6. Operation and Adjustment
After successful installation, restore power. The sensor will enter a warm-up period (usually 30-60 seconds) during which it may trigger randomly. After this, it will be ready for adjustment.
Figure 4: Top view of the sensor showing TIME and LUX adjustment dials.
6.1 Time Delay Adjustment (TIME)
The 'TIME' dial controls how long the connected light or device remains ON after motion is detected and then stops. Rotate the dial to set the desired duration:
- Minimum Setting: Approximately 10 seconds.
- Maximum Setting: Approximately 30 minutes.
Adjust clockwise for longer duration, counter-clockwise for shorter duration.
6.2 Light Sensitivity Adjustment (LUX)
The 'LUX' dial determines the ambient light level at which the sensor will become active. This is the twilight switch function.
- Sun Symbol (Max LUX): The sensor will operate both day and night (high ambient light level required to deactivate).
- Moon Symbol (Min LUX): The sensor will only operate in low light conditions (e.g., dusk or night).
Adjust clockwise for higher light sensitivity (operates in brighter conditions), counter-clockwise for lower light sensitivity (operates only in darker conditions).
7. Maintenance
- Cleaning: Regularly wipe the sensor lens with a soft, dry cloth to remove dust or dirt that may obstruct detection. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the sensor for any signs of damage or loose connections.
- Power Off: Always disconnect power before performing any cleaning or inspection.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. | 1. No power supply. 2. LUX setting is too low (moon symbol) for current ambient light. 3. Incorrect wiring. 4. Motion is outside detection range/angle. | 1. Check power supply and circuit breaker. 2. Adjust LUX dial towards the sun symbol. 3. Verify wiring connections (consult electrician). 4. Reposition sensor or move closer to detection area. |
| Light stays on constantly or triggers randomly. | 1. Continuous motion in detection area. 2. Sensor is detecting heat sources (e.g., heater, direct sunlight, moving trees). 3. TIME setting is too long. 4. Faulty sensor. | 1. Ensure no constant motion. Adjust detection area. 2. Reposition sensor away from heat sources or reflective surfaces. 3. Adjust TIME dial to a shorter duration. 4. Contact customer support. |
| Detection range is too short. | 1. Obstructions in detection path. 2. Sensor mounted too high. 3. Environmental factors (e.g., extreme cold). | 1. Clear obstructions. 2. Lower mounting height if possible. 3. Ensure operating within specified temperature range. |
