5. Instalação (Configuração)
Importante: Ensure the main power supply is switched off before commencing installation.
- Escolha a localização: 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.
- Preparar a fiação: Abra o casing of the motion detector. You will find terminals for Live (L), Neutral (N), and Switched Live (L').
- Base de montagem: Secure the base of the motion detector to the ceiling using appropriate screws and wall plugs. Ensure the cable entry points are aligned.
- Conexões de fios:
- 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).

- Fechar Casing: Once wiring is complete and secure, reattach the main body of the detector to its base.
- Restaurar energia: 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.
- Ajustável de 10 segundos a 12 minutos.
- Turn clockwise to increase the time delay, counter-clockwise to decrease.
- SENS (Sensibilidade/Alcance de Detecção): 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).
