## Summary description

Ceiling-mounted microwave motion and presence sensor FF DRM-02 combines microwave detection with presence sensing for automated control of lighting or HVAC. Designed for installation on ceilings, the DRM-02 detects movement and occupancy to trigger circuits, reduce energy use and improve automation in offices, corridors, stairwells and commercial spaces.

## Long description

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.
