Merten Presence Detector Matte Black 180° MEG5710-0403

The Merten Presence Detector MEG5710-0403 is a flush-mounted slave unit designed to extend the detection coverage of a master presence detector in the Merten System M range. Its 180° detection angle and integrated light sensor enable precise, automatic control of lighting and HVAC systems based on occupancy and ambient light levels.

Advantages

With 56 detection zones and 224 switching segments, this detector provides fine-grained presence detection, reducing false triggers and energy waste. The matte black finish blends discreetly into modern interiors, while the UV-stabilized thermoplastic housing ensures long-term durability.

Suitable for

• Offices and meeting rooms requiring occupancy-based lighting control
• Corridors and open-plan areas where multiple detectors are needed
• Integration with Merten System M master units for extended coverage
