FF DRO-11 Microwave Presence Sensor, 360 Degree, Flush Mount, IP20

The FF DRO-11 is a high-precision microwave presence sensor engineered for seamless automatic lighting control in indoor environments. Designed for flush mounting, this device offers a comprehensive 360-degree detection angle, ensuring that movement is captured from all directions within its range. By utilizing advanced microwave technology, the sensor provides reliable detection through various materials, making it a sophisticated solution for modern building automation and energy management.

Advantages

The primary benefit of the FF DRO-11 is its ability to significantly reduce energy consumption by ensuring lights are only active when a space is occupied. Its flush-mount design allows for a clean, unobtrusive installation that blends into ceilings, maintaining the aesthetic integrity of your interior design. The 360-degree coverage eliminates blind spots, providing consistent performance in complex room layouts. Furthermore, the microwave technology is highly sensitive to even minor movements, ensuring that lighting remains on as long as a person is present in the room.

Suitable for

• Offices and conference rooms
• Residential hallways and corridors
• Storage areas and utility rooms
• Public building stairwells

This sensor may not be suitable for outdoor environments or areas with high humidity, as it carries an IP20 rating which does not provide protection against water ingress. Additionally, because microwave sensors can detect movement through thin walls or glass, it may not be ideal for small rooms where it could inadvertently trigger lights due to activity in adjacent spaces.

Key specifications

• Detection angle: 360 degrees
• Mounting type: Flush mount
• Protection rating: IP20
• Technology: Microwave motion and presence detection
• Application: Indoor use only

To install the FF DRO-11, ensure the power supply is disconnected before beginning any electrical work. The sensor is designed to be recessed into the ceiling. Once the appropriate hole is cut, connect the wiring according to the provided technical diagram, ensuring the load is within the specified capacity. After securing the sensor in the ceiling, restore power and adjust the sensitivity and time delay settings located on the device to match your specific room requirements.

What to consider before purchase

• Verify that the installation location is indoors and dry.
• Ensure the ceiling material is suitable for flush mounting.
• Check that the detection range matches the dimensions of your room.
• Confirm compatibility with your existing lighting fixtures.

For optimal performance, avoid installing the sensor near large metal objects or ventilation ducts, as these can interfere with microwave signals and cause false triggering. Regularly test the detection area to ensure the settings remain appropriate for your usage patterns.
