PIR Motion Sensor MACLEAN MCE231 — Passive infrared motion detector, ceiling/wall mounting

PIR Motion Sensor MACLEAN MCE231 is a passive infrared motion detector intended for indoor use. The device monitors changes in infrared radiation caused by human movement and outputs a switching signal suitable for lighting control or as an alarm input to security systems. The compact housing allows installation on ceilings or walls in corridors, rooms, entrance areas and utility spaces where automatic presence detection is required.

Advantages

The sensor offers reliable passive infrared detection with a compact design that supports both ceiling and wall mounting. It provides quick response to human movement and a simple electrical interface for integration with lighting circuits or alarm systems. The device design focuses on unobtrusive installation and continuous operation for everyday use in residential or commercial interiors.

Suitable for

• Automatic lighting control in corridors and stairwells
• Occupancy detection in rooms and utility spaces
• Triggering alarm inputs for basic security setups
• Energy-saving systems that require presence-based switching

Key specifications

• Detection technology: passive infrared (PIR)
• Mounting options: ceiling or wall
• Intended environment: indoor use
• Typical applications: lighting control, alarm input triggering
• Form factor: compact sensor housing designed for discreet installation

How to use

Mount the sensor on a wall or ceiling at a location that provides an unobstructed view of the monitored area and follow standard wiring practices to connect the sensor output to the lighting control circuit or alarm input. Position the device at a height and angle that maximise coverage of walkways or room entrances while avoiding direct exposure to heating vents or reflective surfaces that may affect detection. After installation, verify operation by walking through the detection zone and checking that the connected load or alarm input responds as expected.

Usage recommendations

For reliable performance, keep the sensor lens free of dust and obstructions, avoid mounting directly opposite large glass surfaces or air-conditioning outlets, and test detection coverage after installation. Use the device indoors only and integrate it into circuits per applicable electrical regulations.
