S451182 Infrared Motion Sensor
User Manual and Installation Guide
Introduction
Welcome to the S451182 infrared motion sensor. This product features a high-sensitivity detector and integrated circuit, offering automation, convenience, safety, energy saving, and practical functionality. It utilizes human infrared energy as a control signal, activating loads instantly when a person enters the detection field. The sensor can automatically identify day and night, making it easy to install and widely applicable.

Functions
- Day and Night Identification: The user can adjust the working state based on ambient light. It operates day and night when set to the "sun" (maximum) position. It works in ambient light less than 3LUX when set to the "3" (minimum) position. Refer to the testing pattern for adjustment details.
- Continuous Time-Delay: When a second induction signal is received within the first induction period, the timer restarts from that moment.
Installation Advice
As the detector responds to temperature changes, avoid the following situations:
- Avoid pointing the detector towards objects with highly reflective surfaces, such as mirrors.
- Avoid mounting the detector near heat sources, such as heating vents, air conditioning units, or lights.
- Avoid pointing the detector towards objects that may move in the wind, such as curtains or tall plants.
Connection and Installation
WARNING: Danger of death through electric shock! Installation must be performed by a professional electrician.
- Disconnect the power source.
- Cover or shield any adjacent live components.
- Ensure the device cannot be switched on accidentally.
- Verify that the power supply is disconnected.
- Slightly rotate the plastic cover to adjust the Time and LUX knobs.
- Remove the transparent cover, loosen the screws on the connection terminal, and connect the power to the sensor terminal according to the connection-wire diagram.
- Fold the metal spring upwards, insert the sensor into the suitable hole or installation box. Releasing the spring will secure the sensor in its installed position.
- After installation is complete, turn on the power and test the unit.

Sensor Information Diagrams Description
These diagrams illustrate the sensor's 360-degree detection coverage and indicate the maximum detection distance of 8 meters. Another diagram specifies the recommended installation height range of 2.2-4 meters.
Testing Procedure
Initial Setup:
- Turn the TIME knob counter-clockwise to the minimum (10s).
- Turn the LUX knob clockwise to the maximum (sun).
Power On and Operation:
- Switch on the power. Initially, the sensor and the connected lamp will show no signal.
- After a 30-second warm-up period, the sensor will start working.
- When an induction signal is received, the lamp will turn on.
- If no further induction signal is detected, the load should stop working within 10sec ± 3sec, and the lamp will turn off.
LUX Adjustment Test:
- Turn the LUX knob counter-clockwise to the minimum (3).
- If ambient light is above 3LUX, the sensor will not work, and the lamp will remain off.
- If ambient light is below 3LUX (darkness), the sensor will work.
- In the absence of an induction signal, the sensor should stop working within 10sec ± 3sec.
Note: When testing in daylight, please turn the LUX knob to the (SUN) position, otherwise the sensor lamp may not work.
Troubleshooting
Problem: The load does not work:
- a. Check if the power source and load connections are correct.
- b. Ensure the load (e.g., lamp) is functioning correctly.
- c. Verify that the working light settings (LUX) match the ambient light conditions.
Problem: Sensitivity is poor:
- a. Check for any obstructions in front of the detector that might affect signal reception.
- b. Ensure the ambient temperature is not too high.
- c. Confirm the induction signal source is within the detection field.
- d. Verify that the installation height matches the requirements specified in the instructions.
- e. Check if the direction of movement is correct relative to the sensor.
Problem: The sensor cannot automatically shut off the load:
- a. Ensure there is no continuous signal within the detection field.
- b. Check if the time delay is set to the maximum position.
- c. Verify that the load power matches the instructions.
