Ceiling-mounted microwave motion and presence sensor FF DRM-02, model DRM-02

FF Mikrofalowy czujnik ruchu z funkcją czujnika obecności montaż na suficie (DRM-02) is a ceiling-mounted microwave motion sensor designed to detect movement and presence within interior spaces. The sensor uses microwave technology to monitor activity across a coverage area while distinguishing between transient motion and sustained presence. Its compact design is intended for unobtrusive installation on ceilings in residential and commercial environments.

Advantages

The sensor provides reliable motion detection with microwave sensitivity, allowing for detection through certain non-metallic materials and improved coverage compared to some passive infrared devices. It includes presence-detection capability to maintain lighting or HVAC control when occupants are stationary, reducing false offs. Ceiling mounting offers wide-area coverage and a discreet footprint for integration into existing lighting or automation systems.

Suitable for

• Indoor ceiling installations in offices and meeting rooms
• Corridors and stairwells requiring automatic lighting control
• Residential spaces such as kitchens, hallways, and utility rooms
• Commercial areas where presence detection improves energy efficiency

Key specifications

• Detection technology: microwave motion and presence detection
• Mounting type: ceiling-mounted design for overhead installation
• Coverage: wide-angle detection suitable for open interior spaces
• Operating environment: intended for indoor use in conditioned spaces
• Integration: compatible with standard lighting and control circuits

How to use

Install the sensor on a ceiling surface following electrical safety standards and local regulations. Position the device centrally in the area to be monitored to ensure the broadest coverage. Connect the sensor to the lighting or control circuit according to the system wiring scheme, and set sensitivity and time-delay parameters as required for the specific application. After installation, test detection zones and adjust orientation or sensitivity settings to minimize false triggers and ensure reliable presence detection.

Usage recommendations

For optimal performance, avoid mounting near large metal objects or HVAC vents that can affect microwave propagation. Calibrate sensitivity and timeout settings to match typical occupancy patterns of the space. Periodic functional checks and correct installation height will help maintain consistent detection and energy-saving operation.
