Passive infrared (PIR) motion detector MACLEAN MCE201B — wired wall sensor, 12 m range, black

MACLEAN MCE201B is a wired passive infrared (PIR) motion detector intended for indoor wall installation. The detector senses movement up to 12 m and is housed in a black enclosure designed to blend with indoor decor. It is powered from 220–240 V AC (50/60 Hz) and has a typical power consumption of 0.5 W, providing continuous presence monitoring for alarm systems, lighting control or automation tasks in homes, offices and commercial interiors.

Advantages

The MACLEAN MCE201B offers a wide detection range and low power consumption in a compact, black wall-mounted housing. Its PIR sensing technology provides reliable detection of human motion while reducing false alarms from non-thermal disturbances. Hardwired connection ensures stable operation without the need for batteries, and the unit’s design supports straightforward integration into existing wired alarm or automation systems.

How to use

Install the detector at the recommended height on an interior wall facing the area to be monitored, following applicable wiring and safety standards. Connect the unit to the building’s low-voltage alarm/automation wiring or mains supply as required by the installation instructions and local electrical codes. After powering the device, verify detection coverage by walking through the protected zone and adjust mounting position if necessary to avoid blind spots. Ensure wiring is secured and any system-level settings, such as trigger delays or sensitivity adjustments provided by the connected control panel, are configured appropriately.

Recommendations

For reliable performance, avoid aiming the sensor at air-conditioning vents, direct sunlight or reflective surfaces. Place the detector so that its field of view covers pedestrian paths rather than areas with frequent small heat sources. Regularly inspect the mounting and wiring, and keep the front lens clean from dust and obstructions to maintain optimal detection sensitivity.
