- Disconnect power before installation or any maintenance.
- Do not exceed the maximum load capacity: 800W for incandescent lamps, 300W for LED or other energy-saving lamps.
- This device is designed for indoor use only (IP20 rating). Do not expose to moisture or extreme temperatures.
- Ensure the mounting surface is stable and can support the device.
- Keep out of reach of children.
3. Product Overview
The SEBSON HF Motion Detector utilizes high-frequency (HF) technology to detect movement within its coverage area. It is designed for ceiling surface mounting and offers adjustable settings for optimal performance in various indoor environments.
Key Features:
- High-Frequency Sensor: Detects movement through non-metallic objects like thin walls or doors.
- Wide Coverage: 360° detection angle with a range of 2 to 16 meters.
- Adjustable Settings: Time delay (10 seconds to 12 minutes), sensitivity (detection range), and ambient light threshold (3-2000 lux).
- LED Compatible: Supports up to 300W for LED lamps and 800W for incandescent lamps.
- Compact Design: Circular, white casing with dimensions of Ø100x22mm.

5. Installation (Setup)
Important: Ensure the main power supply is switched off before commencing installation.
- Choose Location: Select a suitable indoor ceiling location for surface mounting. Avoid placing near heat sources, air conditioning vents, or areas with significant air movement, which can interfere with detection.
- Prepare Wiring: Open the casing of the motion detector. You will find terminals for Live (L), Neutral (N), and Switched Live (L').
- Mount Base: Secure the base of the motion detector to the ceiling using appropriate screws and wall plugs. Ensure the cable entry points are aligned.
- Wire Connections:
- Connect the incoming Live wire to the 'L' terminal.
- Connect the incoming Neutral wire to the 'N' terminal.
- Connect the Live wire to your light fixture (load) to the 'L'' terminal.
- Connect the Neutral wire from your light fixture (load) to the 'N' terminal (shared with incoming neutral).

- Close Casing: Once wiring is complete and secure, reattach the main body of the detector to its base.
- Restore Power: Switch on the main power supply. The detector will enter a warm-up period (typically 30-60 seconds) during which it may switch on and off randomly.
6. Operation and Settings Adjustment
The SEBSON HF Motion Detector features three adjustable dials to customize its operation:
- TIME (Time Delay): Controls how long the connected light remains on after the last detected movement.
- Adjustable from 10 seconds to 12 minutes.
- Turn clockwise to increase the time delay, counter-clockwise to decrease.
- SENS (Sensitivity/Detection Range): Adjusts the detection range of the HF sensor.
- Adjustable from 2 meters to 16 meters.
- Turn clockwise for higher sensitivity (longer range), counter-clockwise for lower sensitivity (shorter range).
- Consider the environment to avoid unwanted detections (e.g., through thin walls).
- LUX (Ambient Light Threshold): Determines the ambient light level at which the sensor will activate the connected light.
- Adjustable from 3 lux (darkness) to 2000 lux (daylight).
- Turn towards the sun icon for activation in brighter conditions (daylight).
- Turn towards the moon icon for activation only in darker conditions (night).
