Introduction
The ORNO CR-211/12-24V is a compact infrared (PIR) motion sensor designed for automatic control of LED lighting or other electrical devices. It features a 360-degree detection angle, a built-in twilight sensor, and adjustable time and light intensity settings, making it ideal for energy-saving applications in both private and professional environments. This manual provides detailed instructions for safe installation, operation, and maintenance of your device.
Product Features
- Wide Voltage Compatibility: Operates with 12-24V DC power supplies, suitable for various low-voltage applications.
- 360-Degree Detection: Provides comprehensive coverage, detecting motion from all directions.
- Integrated Twilight Sensor: Activates the sensor only when ambient light falls below a set threshold, optimizing energy use.
- Adjustable Timer: Allows customization of the illumination duration from 5 seconds to 8 minutes after motion detection.
- Adjustable Light Sensitivity (LUX): Set the ambient light level (10 or 2000 lux) at which the sensor becomes active.
- LED Compatible: Designed to work with all types of LED light sources, requiring a minimum load of 1W.
- Compact Design: Miniaturized sensor head for discreet installation.
Safety Information
Please read these safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or other hazards.
- Installation must be performed by a qualified electrician in accordance with local electrical codes and regulations.
- Ensure the power supply is disconnected before performing any installation, maintenance, or troubleshooting.
- This device is designed for 12-24V DC systems only. Connecting it to a higher voltage (e.g., 230V AC) will damage the unit and pose a safety risk.
- Do not exceed the maximum load capacity of 60-120W.
- The device has an IP20 protection rating, meaning it is protected against solid objects larger than 12.5mm but has no protection against water. Do not install in wet or damp locations.
- Keep the sensor away from heat sources, direct sunlight, and strong air currents (e.g., from air conditioners) to prevent false triggers.

Setup and Installation
The ORNO CR-211/12-24V motion sensor is designed for discreet installation. The main control unit can be hidden, while the small sensor head is exposed for detection.
Mounting
- Choose a suitable location for the sensor head. It should be free from obstructions and positioned to cover the desired detection area.
- Drill a mounting hole with a diameter of Ø12mm for the sensor head.
- Insert the sensor head into the drilled hole.
- Secure the main control unit in a hidden, dry location, ensuring proper ventilation. The unit is suitable for surface mounting.
Wiring Diagram
Refer to the diagram below for correct wiring. Ensure the power supply is off before connecting any wires.
- Input (Power Supply 12-24V DC): Connect the positive (+) lead of your 12-24V DC power supply to the appropriate input terminal (often marked with a '+' or red wire). Connect the negative (-) lead to the corresponding terminal (often marked with a '-' or blue wire).
- Output (Load Connection): Connect your LED lighting or other electrical device to the output terminals. Ensure the load's voltage and wattage are compatible with the sensor's specifications (12-24V DC, 60-120W max).
After wiring, restore power and proceed to the operating instructions and adjustments.
Operating Instructions
Once installed and powered, the sensor will operate according to its settings. When motion is detected within its 360-degree field of view and the ambient light level is below the set LUX threshold, the connected load (e.g., LED lights) will turn on for the duration set by the timer.
The sensor uses passive infrared (PIR) technology to detect changes in infrared radiation caused by moving objects (like people or animals). For optimal performance, ensure the sensor lens is clean and unobstructed.
Adjustments
The ORNO CR-211/12-24V features DIP switches for adjusting the operating time and light sensitivity (LUX level). These switches are located on the main control unit.
Time Adjustment
The timer determines how long the connected load remains active after motion is detected. The available settings are:
- 5 seconds
- 30 seconds
- 1 minute
- 3 minutes
- 5 minutes
- 8 minutes
Consult the markings next to the DIP switches on your device for the specific switch combinations corresponding to each time setting.
Light Sensitivity (LUX) Adjustment
The LUX setting determines the ambient light level at which the sensor will activate. This allows the sensor to only turn on lights when it's dark enough.
- 10 LUX: The sensor will only activate in very dark conditions.
- 2000 LUX: The sensor will activate in almost all lighting conditions (day and night).
Adjust the LUX setting using the designated DIP switch according to your preference. For example, set to 10 LUX if you only want lights to turn on at night.
Maintenance
The ORNO CR-211/12-24V motion sensor requires minimal maintenance.
- Cleaning: Periodically wipe the sensor lens with a soft, dry cloth to remove dust or dirt that might interfere with detection. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check the wiring connections to ensure they are secure and free from damage.
- Environment: Ensure the operating environment remains within the specified temperature range and free from excessive moisture.
Troubleshooting
If you experience issues with your motion sensor, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on when motion is detected. |
|
|
| Lights stay on constantly. |
|
|
| Sensor triggers too often or falsely. |
|
|
| Incorrect voltage applied. | Connecting to 230V AC instead of 12-24V DC. | Immediately disconnect power. The device is likely damaged and requires replacement. This sensor is strictly for 12-24V DC. |
