Motion detector Merten MEG5628-3115

The Merten MEG5628-3115 motion detector is a wired passive infrared (PIR) sensor designed for outdoor environments. It provides reliable presence detection at distances up to 16 meters and is intended for fixed installation on ceilings or walls. The unit operates from AC mains (220–230 V) and consumes approximately 1 W in normal operation. Its compact housing (93 mm × 71 mm × 151 mm) and brown finish are suited to blend with many exterior facades and outdoor mounting locations.

Advantages

The motion detector offers a combination of long detection range and low power consumption suitable for continuous or intermittent outdoor use. Its wired AC operation ensures stable power supply and avoids the need for battery replacement. The compact dimensions allow flexible installation in constrained spaces, and the brown housing reduces visual contrast on many building exteriors. The PIR technology provides passive, contactless detection with low maintenance requirements.

How to use

Install the MEG5628-3115 in a suitable outdoor location at the recommended height and orientation to cover the required detection area. Connect the detector to the mains supply and to the controlled lighting circuit following local electrical codes and the manufacturer’s wiring guidelines. After power-up, test the detection field by walking through the monitored zone to confirm coverage up to 16 meters and adjust the mounting angle or position as needed. Routine checks should confirm secure mounting and absence of obstructions in front of the sensor.

Recommendations

Place the detector to avoid direct exposure to strong light sources or heaters that may cause false triggers. Ensure the sensor has an unobstructed field of view and is mounted at an appropriate height for the intended coverage. For reliable operation in outdoor conditions, use weather-protected junctions and follow local regulations for electrical installations.
