Dinuy DM.TEC.004 Recessed Ceiling Detector User Manual
Model: DM.TEC.004
Introduction
This manual provides comprehensive instructions for the installation, operation, maintenance, and troubleshooting of the Dinuy DM.TEC.004 Recessed Ceiling Detector. Please read this manual carefully before installation and use to ensure proper function and safety.
The Dinuy DM.TEC.004 is a 360-degree motion detector designed for recessed ceiling installation, capable of detecting movement within a 6.6-meter diameter area. It is suitable for various applications requiring automatic lighting control based on occupancy.
Product Overview
Figure 1: Dinuy DM.TEC.004 Recessed Ceiling Detector showing the sensor unit and the control unit.
The Dinuy DM.TEC.004 consists of two main parts:
- Sensor Unit: This is the circular part designed for recessed ceiling mounting. It contains the passive infrared (PIR) sensor for motion detection and adjustable controls for LUX (light sensitivity) and TIME (detection duration).
- Control Unit: This rectangular unit houses the electrical connections and control circuitry. It connects to the sensor unit and the main power supply.
Key features include a 360-degree detection angle and a maximum detection diameter of 6.6 meters, making it ideal for large rooms or open spaces.

Setup and Installation
Safety Precautions
- Installation must be performed by a qualified electrician in accordance with local wiring regulations.
- Ensure the main power supply is switched off before commencing any installation work.
- Do not install in areas with high humidity, extreme temperatures, or direct sunlight.
- Avoid installing near heat sources or air conditioning vents, as this may affect sensor performance.
Installation Steps
- Prepare the Ceiling: Cut a circular hole in the ceiling at the desired installation location. Refer to the product packaging or technical drawings for the exact diameter required for the sensor unit.
- Wiring the Control Unit:
- Connect the Live (L) wire from the main power supply to the 'L' terminal on the control unit.
- Connect the Neutral (N) wire from the main power supply to the 'N' terminal on the control unit.
- Connect the switched Live (L') output from the control unit to the Live terminal of the light fixture or load.
- Connect the Neutral wire from the light fixture or load to the 'N' terminal on the control unit (or directly to the main neutral if applicable).
- Ensure all connections are secure and insulated.
- Connecting Sensor to Control Unit: Connect the cable from the sensor unit to the corresponding terminals on the control unit. The terminals are typically marked with symbols or colors to ensure correct polarity.
- Mounting the Control Unit: Secure the control unit in a suitable location, typically within the ceiling void, ensuring it is accessible for future maintenance if needed.
- Mounting the Sensor Unit: Insert the sensor unit into the prepared ceiling hole. The spring clips on the sides of the sensor unit will secure it in place. Ensure the sensor lens is clear and unobstructed.
- Restore Power: Once all connections are made and secured, restore power to the circuit.
Note: The optimal installation height for the detector is typically between 2.2m and 4m for effective 360-degree coverage.
Operating Instructions and Adjustments
The Dinuy DM.TEC.004 detector features two adjustable controls on the sensor unit:
- LUX (Light Sensitivity): This knob adjusts the ambient light level at which the detector will activate.
- Turn towards the sun symbol (max) for activation regardless of ambient light (daylight and nighttime).
- Turn towards the moon symbol (min) for activation only in low light conditions (nighttime).
- TIME (Detection Duration): This knob sets how long the connected load (e.g., lights) remains on after motion is last detected.
- Turn towards '+' to increase the duration.
- Turn towards '-' to decrease the duration.
- Typical range is from a few seconds to several minutes.
Testing: After installation, set the LUX to maximum (sun symbol) and TIME to minimum. Walk through the detection area to verify the sensor activates the load. Adjust TIME to the desired duration. Then, adjust LUX to the desired ambient light level for activation.
Maintenance
The Dinuy DM.TEC.004 detector requires minimal maintenance. Follow these guidelines:
- Cleaning: Periodically wipe the sensor lens with a soft, dry cloth to remove dust or dirt that may obstruct detection. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the wiring connections for any signs of wear, corrosion, or loosening. Ensure the sensor unit is securely mounted in the ceiling.
- Power Off for Maintenance: Always switch off the main power supply to the detector before performing any cleaning or inspection.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not activate load. | No power supply. Incorrect wiring. LUX setting too high (daylight mode, but it's dark). Sensor obstructed. | Check power supply. Verify wiring according to diagram. Adjust LUX setting towards 'sun' symbol for testing, then to desired level. Ensure sensor lens is clear. |
| Load remains on constantly. | Continuous motion in detection area. TIME setting too long. Faulty sensor. | Ensure no constant motion. Reduce TIME setting. If problem persists, contact support. |
| Load activates without apparent motion. | Heat sources (e.g., heater, sunlight) in detection area. Air currents (e.g., AC vents). Small animals. Sensor sensitivity too high. | Relocate detector away from heat sources/vents. Adjust sensor position or sensitivity if possible (not directly adjustable on this model, but placement helps). |
| Detection range is poor. | Incorrect installation height. Obstructions. Temperature difference between ambient and moving object is small. | Verify installation height is optimal (2.2m-4m). Remove obstructions. This is inherent to PIR technology; ensure clear line of sight. |
If the problem persists after attempting these solutions, please contact Dinuy customer support or a qualified electrician.
