PIR motion sensor MACLEAN MCE313W — non-contact presence detector, passive infrared

MACLEAN MCE313W is a PIR non-contact motion sensor that uses passive infrared detection to identify presence and movement. Designed for installation in security, lighting control and automation systems, the MCE313W detects changes in infrared radiation emitted by people and warm objects to trigger alarms, lights or control circuits. The compact indoor sensor provides automatic presence detection without physical contact and is intended for environments where reliable motion sensing is required.

Advantages

The MACLEAN MCE313W employs passive infrared technology for low false-trigger rates and stable operation in indoor spaces. Its non-contact detection reduces wear and avoids mechanical parts, while a focused detection pattern enables consistent response to human movement. The sensor is compatible with common control systems for lighting and alarms, supporting straightforward integration into existing installations. Its design emphasizes discreet mounting and continuous monitoring of occupancy and motion.

Suitable for

• Room occupancy detection in offices and commercial premises
• Automatic lighting control in corridors, stairwells and storage areas
• Integration with alarm and security systems for motion-triggered alerts
• Energy-saving automation where presence-based switching is required

Key specifications

• Detection technology: passive infrared (PIR)
• Application: indoor presence and motion detection
• Output: control signal for alarms, lighting or automation circuits
• Mounting: wall or ceiling mounting suitable for discrete installation
• Operation: non-contact sensing of infrared radiation changes

How to use

Install the MACLEAN MCE313W following the mounting recommendations for the required coverage area and connect its output to the target control device or circuit in the security, lighting or automation system. Position the sensor to avoid direct exposure to heat sources or reflective surfaces that could affect detection. After wiring, test the detection field and adjust placement as needed to ensure reliable triggering by occupants while minimising unwanted activations.

Usage recommendations

For reliable performance, mount the sensor at a height and orientation that match the monitored area and keep it clear of vents, direct sunlight and heat-producing equipment. Use the MCE313W together with appropriate control modules or alarm panels compatible with passive infrared outputs to achieve stable automation and energy-saving operation.
