Motion Detector Merten MEG5628-3160

The Motion Detector Merten MEG5628-3160 by Schneider Electric is a wired passive infrared (PIR) sensor designed for ceiling or wall mounting. Finished in aluminum, it is built for outdoor placement and integrates into AC 230V installations. The detector provides motion sensing up to 16 meters while consuming approximately 1 W of power. Compact dimensions (93 mm width × 71 mm depth × 151 mm height) make it suitable for locations where a discreet, low-profile presence is required for security and automation systems.

Advantages

The device combines a PIR sensing element with a robust aluminum housing that resists outdoor conditions and supports reliable long-term operation. Low standby power consumption helps reduce energy use in continuous installations. Its wired AC connection ensures steady power without the need for batteries, and the detection range covers medium to large outdoor areas. The compact form factor simplifies mounting in ceilings or on walls where space is limited.

Suitable for

• Perimeter and exterior lighting automation
• Outdoor security detection for entrances, pathways, and driveways
• Integration with building automation and alarm systems
• Areas requiring ceiling- or wall-mounted motion detection with a discreet profile

How to use

Install the motion detector according to local electrical codes, mounting it on a stable ceiling or wall surface at a height and orientation that provides optimal coverage for the target area. Connect the device to the building's AC 230 V supply through appropriate wiring and protective devices. Configure any linked lighting, alarm, or automation equipment so that the detector output controls the desired load or system input. After installation, perform a functional test by moving through the detection zone and verifying that the connected equipment responds as expected.

Recommendations

For reliable performance, avoid installing the detector near heat sources, air conditioning vents, or objects that cause rapid temperature changes. Ensure the sensor has an unobstructed field of view and that mounting height and orientation match the coverage required. Regularly check connections and housing integrity in outdoor environments to maintain long-term operation.
