Function
Smart Day & Night Light Sensing: You can easily adjust the LUX control dial to dictate precisely when the sensor activates based on surrounding ambient light conditions.
24/7 Continuous Mode (“Sun” / Max): Setting the dial to the “Sun” position enables the unit to detect motion and trigger connected loads around the clock, operating seamlessly during both bright daylight and total darkness.
Night-Only Energy Saver Mode (“Moon” / Min): Turning the dial toward the “Moon” position restricts activation strictly to low-light environments below 3 LUX, effectively preventing unnecessary daytime power consumption.
Continuous Auto-Reset Time Delay: To guarantee uninterrupted lighting while an area remains occupied, the sensor automatically restarts its delay timer the moment it registers any secondary motion signal during an active cycle. Consequently, it maintains continuous power to your connected loads without sudden shut-offs or flickering.
Note: For step-by-step dial calibration and initial setup instructions, please refer to the Installation Manual
Important Installation & Placement Guidelines
Because PIR motion sensors detect sudden changes in thermal radiation and temperature differentials, improper placement can lead to false triggers or reduced sensitivity. To ensure flawless, long-term performance from your sensor, keep the following installation advice in mind:
Keep Away from Reflective Surfaces: Avoid aiming the detector toward mirrors, polished glass, or highly reflective panels. These surfaces bounce thermal energy and daylight around the room, which can inadvertently trigger false activations.
Maintain Distance from Climate Control & Heat Sources: Do not mount the unit in close proximity to heating vents, air conditioning outlets, high-wattage light fixtures, or radiational heaters. Rapid thermal shifts near these fixtures directly disrupt the sensor's internal calibration.
Avoid Drafts and Moving Objects: Refrain from pointing the lens directly at objects susceptible to breeze or air movement, such as hanging curtains, blinds, or tall indoor plants. Wind-driven motion across these surfaces creates shifting thermal patterns that the sensor may misinterpret as human movement.
Safety Warnings & Installation Procedure
⚠️ DANGER: RISK OF ELECTRIC SHOCK & SEVERE INJURY
Electrical installation must be performed strictly by a qualified, licensed electrician. Always disconnect the main power supply before beginning installation or maintenance to prevent electric shock or equipment damage.
Pre-Installation Safety Steps
Disconnect Main Power: Shut off the primary circuit breaker or isolate the electrical supply feeding the installation area.
Prevent Accidental Re-energization: Secure the breaker box or switch panel to ensure no one can accidentally restore power while you are working.
Verify Zero Voltage: Use a reliable voltage tester on the supply wires to confirm that power is completely disconnected before touching any components.
Isolate Nearby Conductors: Cover or shield any adjacent live electrical components in the junction box or wall cavity to prevent unintended contact.
Step-by-Step Installation Instructions
Step 1: Open the Sensor Housing
Loosen the securing screw located on the bottom base of the unit, then carefully detach the mounting plate from the main sensor body.
Step 2: Route the Wiring
Feed your incoming main power lines and load control wires through the rubber gasket hole on the back of the base plate to maintain weather sealing and wire protection.
Step 3: Wire the Terminals
Connect the live, neutral, and load wires securely into the terminal block, following the designated wiring diagram precisely to avoid incorrect operation or short circuits.
Step 4: Mount the Base Plate
Position the backplate against the mounting surface, mark your drilling points, and fix it firmly in place using the provided wall plugs (inflated screws) and mounting hardware.
Step 5: Reassemble and Test
Align the main sensor body back onto the mounted base plate, tighten the locking screw on the bottom to secure it, restore power to the circuit, and proceed with testing the detection settings.
Step-by-Step Testing & Calibration Guide for Weather proof PIR Sensor
Follow this initial testing procedure to verify that your sensor's detection, timer, and light-level settings function correctly before final operation.
Initial Setup & Adjustment Parameters
Set Light Sensitivity (LUX): Turn the LUX control knob fully clockwise to the maximum (Sun) position.
Set Delay Time (TIME): Turn the TIME control knob fully counter-clockwise to the minimum (-) setting (approx. 10 seconds).
Testing Procedure
Warm-Up Phase: Switch on the main electrical power. Neither the connected load (light/appliance) nor the indicator lamp will operate immediately. The unit requires a 30-second warm-up period to calibrate its internal circuits, after which the indicator lamp turns on.
Initial Motion Test: In the absence of any motion signal, the indicator light turns off, and the connected load automatically shuts off within 10 seconds ($\pm 3$ seconds).
Secondary Detection Test: Wait 5 to 10 seconds after the initial load turns off, then step into the sensor's detection zone. The sensor should immediately detect your movement, re-energize the load, and turn off again 10 seconds ($\pm 3$ seconds) after motion stops.
Daylight Sensor (LUX) Test: Turn the LUX knob fully counter-clockwise to the minimum (Moon) setting.
If the ambient light level is above 3 LUX (daylight conditions), the sensor actively blocks activation, keeping the connected load off even when movement occurs.
To test night functionality during the day, cover the detection lens with an opaque object (such as a towel or dark cloth). The sensor should trigger the load, which will then turn off within 10 seconds ($\pm 3$ seconds) after motion ceases under the cover.
📌 Important Testing Notes:
Daylight Testing Requirement: Always ensure the LUX knob is turned to the (SUN) position when testing during daylight hours; otherwise, the sensor will prevent the lamp from illuminating.
Minimum Separation Distance: If the connected lighting load exceeds 60W, maintain a minimum distance of at least 60 cm between the lamp and the sensor lens to prevent heat emitted by the bulb from causing false triggers.

Troubleshooting & Problem Resolution Guide
If your sensor isn't performing as expected, use the following guide to diagnose and resolve common operational issues:
1. The Connected Load Does Not Work
Verify Electrical Wiring: Ensure that the main power supply line and the load connection wires are securely wired to the correct terminals according to the wiring diagram.
Inspect the Connected Load: Test the connected lamp or appliance separately to confirm that the load unit itself is functional and not burned out or defective.
Check Ambient Light (LUX) Settings: Confirm whether the LUX setting matches your current environment. If testing in daylight, ensure the LUX knob is adjusted toward the "Sun" position; if set to "Moon," the sensor will deliberately keep the load off in bright lighting.
2. Poor Detection Sensitivity
Clear Optical Obstructions: Inspect the sensor lens window and ensure no physical barriers, covers, or debris block its field of view.
Account for High Ambient Temperature: Note that PIR sensors detect thermal differences. If ambient room temperatures approach body temperature ($\approx 37^\circ\text{C}$), the detection sensitivity naturally decreases.
Verify Sensor Coverage: Confirm that the movement occurs fully within the active detection zone and coverage distance specified for the model.
Check Installation Height: Verify that the sensor is mounted within the recommended height range ($1.8\text{ m} - 2.5\text{ m}$ for wall-mount units or $2.2\text{ m} - 4.0\text{ m}$ for ceiling-mount units).
Evaluate Direction of Motion: PIR sensors detect lateral movement across their detection zones much more effectively than direct movement toward or away from the lens. Ensure the target approach path crosses the sensor's beams horizontally.
3. The Sensor Will Not Shut Off Automatically
Check for Continuous Motion Signals: Ensure no ongoing movement, warm air drafts, swaying curtains, or heat sources (such as HVAC vents or light bulbs) are triggering continuous thermal signals in the detection area.
Verify Time-Delay Setting: Check whether the TIME control knob is set to its maximum duration, which keeps the load energized for up to 7 to 15 minutes after motion stops.
Confirm Load Compatibility: Ensure the total wattage and current draw of your connected load do not exceed the sensor's maximum rated capacity, as overloading can fuse internal relay contacts.
