Ceiling PIR Motion Sensor
Ceiling PIR Motion Sensor 360°- 1L-PS012
Welcome to use 1L-PS012 Ceiling Mount PIR Sensor
The 1L-PS012 Ceiling Mount PIR Sensor 360° adopts a high-sensitivity detector paired with an integrated circuit, seamlessly combining automatism, convenience, safety, and energy efficiency. By utilizing infrared energy emitted from human motion as its control-signal source, the sensor instantly activates connected loads the moment someone enters its 360° detection field. This advanced sensor automatically identifies day and night conditions, intelligently regulating lighting to operate only when ambient light levels demand it.
Designed for long-life operation and low power consumption, the 1L-PS012 provides a dependable, hands-free automation solution for modern spaces. It is easy to install and widely used across commercial buildings, residential setups, and industrial facilities to refine lighting control, enhance safety, and eliminate unnecessary energy waste.

Functions
Smart Day & Night Light Sensing: You can easily adjust the LUX control dial to dictate precisely when the sensor activates based on ambient light levels.
24/7 Continuous Mode ("Sun" / Max): Setting the dial to this position enables the unit to detect motion and trigger connected lights around the clock, operating seamlessly during both full daylight and complete darkness.
Night-Only Energy Saver Mode ("3" / Min): Turning the dial toward this setting restricts activation strictly to low-light environments below 3 LUX, effectively preventing unnecessary daytime power usage.
Continuous Auto-Reset Time Delay: To guarantee uninterrupted lighting while an area is in use, the sensor automatically restarts its delay timer the moment it registers any secondary motion within an active cycle. Consequently, it maintains continuous power to your connected loads for as long as people occupy the space.
Note: For step-by-step dial calibration and initial setup instructions, please refer to the testing pattern section below.

Installation Advice:-
As the detector responds to changes in temperature, avoid the following situations:
- Avoid pointing the detector towards objects with highly reflective surfaces, such as mirrors etc
- Avoid mounting the detector near heat sources, such as heating vents, air conditioning units, light etc.
- Avoid pointing the detector towards objects that may move in the wind, such as curtains, tall plants etc

Connection:-
Warning. Danger of death through electric shock!
- Must be installed by professional electrician.
- Disconnect power source.
- Cover or shied any adjacent live components
- Ensure device cannot be switched on.
- Check power supply is disconnected.
- Please move the upper cover with anti-clockwise whirl as per the diagram on the right.
- Connect the power and the load according to the connection-wire diagram
- Fix the bottom on the selected position with the inflated screw
- Install back the upper cover on the sensor, then you could switch on the power and test it.

Sensor Information:-


Test:-
- Turn the TIME knob anti-clockwise on the minimum (10s).Turn the LUX knob clockwise on the maximum (sun).
- Switch on the power; the sensor and its connected lamp will have no signal at the beginning. After Warm-up 30sec, the sensor can start work .If the sensor receives the induction signal, the lamp will turn on. While there is no another induction signal any more, the load should stop working within 10sec±3sec and the lamp would turn off.
- Turn LUX knob anti-clockwise on the minimum (3). If the ambient light is more than 3LUX, the sensor would not work and the lamp stop working too. If the ambient light is less than 3LUX (darkness), the sensor would work. Under no induction signal condition, the sensor should stop working within 10sec±3sec

Note: when testing in daylight, please turn LUX knob to (SUN) position, otherwise the sensor lamp could not work! If the lamp is more than 60W, the distance between lamp and sensor should be 60cm at least.
Some Problem and Solved Way
The load does not work:
- Please check if the connection of power source and load is correct.
- Please check if the load is good
- Please check if the settings of working light correspond to ambient light
The sensitivity is poor:
- Please check if there is any hindrance in front of the detector to affect it to receive the signals
- Please check if the ambient temperature is too high.
- Please check if the induction signal source is in the detection field
- Please check if the installation height corresponds to the height required in the instruction.
- Please check if the moving orientation is correct
The sensor can not shut off the load automatically:-
- Please check if there is continual signal in the detection field.
- Please check if the time delay is set to the maximum position
- Please check if the power corresponds to the instruction
