5. Installation Guide
Follow these steps for proper installation of your SANSI flood light:
- Prepare for Installation: Turn off power at the circuit breaker. Ensure the mounting surface is secure and can support the fixture.
- Fix the Mounting Plate: Secure the mounting plate onto the junction box using the provided screws.
- Connect the Wires: Connect the black (hot) wire, white (negative) wire, and green (ground) wire from the fixture to your household wiring using wire nuts. Ensure connections are tight and secure.
- Mount the Light Fixture: Attach the LED light fixture to the mounting plate.
- Choose the Working Mode: Select your desired operating mode (Auto, On-Time, D2D) using the switch on the motion sensor.

6. Operating Modes
The SANSI flood light offers three primary operating modes, selectable via a switch on the motion sensor:
- AUTO (Motion Sensor Mode): The light turns on for 1-10 minutes at night when motion is detected. It stays off during the day.
- Dusk to Dawn Mode: The light automatically turns on at dusk and turns off at dawn, providing continuous illumination throughout the night.
- On-Time Mode: The light functions like a normal light, controlled manually by a wall switch. It stays on until manually turned off.
- Test Mode: For verifying proper function during installation. The light turns on for 5 seconds during daytime or night once it detects motion.

7. Adjustments
The motion sensor and light heads are adjustable to customize performance:
- Motion Sensor Adjustment: The sensor head can be adjusted 180° horizontally and 90° vertically to optimize detection area. Use the adjustment screws to loosen, position, and tighten.
- Light Head Adjustment: Each light head can be adjusted 180° horizontally and 90° vertically to direct illumination where needed. Loosen the screws, position the heads, and tighten securely.
- LUX (Brightness Sensitivity): Adjusts the ambient light level at which the motion sensor becomes active. Turn towards '0' for activation in darker conditions, towards 'infinity' for activation in brighter conditions. A halfway setting is often recommended.
- Time: Sets the duration the light stays on after motion is detected, typically from 1 to 10 minutes.
- Range: Adjusts the motion detection distance, up to a maximum of 72 feet.

8. Maintenance
To ensure optimal performance and longevity of your flood light:
- Cleaning: Periodically clean the fixture with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check for any loose connections, damaged wiring, or signs of wear. Address any issues promptly.
- Sensor Area: Keep the motion sensor lens clear of obstructions (e.g., dirt, spiderwebs) to maintain accurate detection.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power; incorrect wiring; sensor setting too low (LUX); bulb failure. | Check circuit breaker. Verify wiring connections. Adjust LUX setting. Contact support if LEDs are faulty. |
| Light stays on continuously. | Mode set to On-Time or D2D; continuous motion detected; sensor malfunction. | Check mode switch. Ensure no constant motion in detection area. Adjust sensitivity. |
| Light turns on for no apparent reason (false triggers). | High sensitivity; environmental factors (wind, small animals, heat sources); sensor obstructed. | Reduce Range and/or LUX sensitivity. Clear obstructions from sensor. Reposition sensor if necessary. |
| Motion detection range is too short. | Low sensitivity; sensor obstructed; incorrect sensor angle. | Increase Range sensitivity. Clear obstructions. Adjust sensor angle. |
