Occupancy PIR Motion Sensor MACLEAN MCE358 B — passive infrared occupancy detector for automatic lighting control

Occupancy PIR Motion Sensor MACLEAN MCE358 B is a passive infrared occupancy detector designed for automatic control of lighting and other electrical loads. The sensor detects human presence by sensing changes in infrared radiation caused by movement and sends a signal to a connected switch or control circuit to turn lights on or off. Intended for indoor use, it is suitable for homes, offices, corridors and utility rooms where automated presence-based lighting control can improve energy efficiency and convenience. The device is compact and designed for straightforward mounting and integration with compatible wiring and control systems.

Advantages

The MACLEAN MCE358 B uses PIR technology for reliable detection of moving heat sources while maintaining low power consumption. Its passive design requires no active emission and offers silent operation without moving parts. The sensor simplifies installation and can reduce energy usage by switching lights off automatically when no presence is detected. The compact form factor supports installation in various indoor locations and integration with standard lighting circuits.

Suitable for

• Residential rooms and hallways where automatic lighting is needed
• Office spaces and meeting rooms for presence-based control
• Corridors and stairwells to maintain safety and save energy
• Utility rooms, storage areas and closets with intermittent occupancy

Key specifications

• Detection principle: passive infrared (PIR)
• Intended installation: indoor mounting
• Detection capability: presence/motion detection for switching loads
• Compatibility: designed to work with standard lighting control circuits and switches
• Power consumption: low standby power (typical for PIR sensors)
• Operating environment: indoor ambient conditions (temperature and humidity ranges typical for indoor electrical equipment)

How to use

Install the Occupancy PIR Motion Sensor MACLEAN MCE358 B according to the wiring instructions supplied with the device and local electrical regulations. Mount the sensor at the recommended height and orientation to cover the desired detection zone, and connect it to the lighting circuit or control input. Adjust any available sensitivity or time-delay settings if present to match room size and typical occupancy patterns. After installation, test the sensor by walking through the detection area to confirm that the lights respond as expected and that automatic switch-off occurs after the set absence interval.

Usage recommendations

For optimal performance, position the detector to avoid direct air drafts from vents or frequent temperature changes and ensure a clear line of sight across the monitored area. Regularly check wiring connections and follow local electrical safety standards when installing or servicing the unit. Use sensitivity and time-delay settings to balance responsiveness and false triggers in environments with pets or intermittent activity.
