## Summary description

MACLEAN MCE203 is an infrared (passive IR) motion sensor designed to detect human movement for occupancy sensing and basic security applications. The device senses changes in infrared radiation to trigger alarms, lights or automation systems. Suitable for indoor installation in homes, offices or retail spaces where motion-based control or monitoring is required.

## Long description

MACLEAN MCE203 is an infrared passive motion sensor designed to detect human movement indoors for occupancy sensing and basic security tasks. The sensor monitors changes in ambient infrared radiation and outputs a switch or signal when motion is detected, enabling automatic control of lighting, alarms or connected automation systems. Its compact form factor and straightforward detection principle make it suitable for mounting on walls or ceilings in residential and commercial interiors.
Advantages
The passive infrared detector provides reliable motion detection with low power consumption and a fast response to sudden changes in infrared levels associated with human presence. The sensor’s simple operation and compact design facilitate easy integration with lighting circuits, alarm panels or smart home controllers. Because it detects heat signatures rather than relying on visible light, it functions effectively in darkness and under varying ambient lighting conditions.
Suitable for
 Automatic switching of indoor lighting in corridors, stairwells and rooms
 Occupancy sensing for energy-efficient HVAC or lighting control
 Basic intruder detection and alarm triggering in homes and small offices
 Integration with building automation systems for presence-based control
Key specifications
 Detection principle: passive infrared (PIR) motion sensing
 Intended environment: indoor use (walls or ceilings)
 Typical applications: occupancy sensing, lighting control, basic security
 Output type: detector trigger or switch signal compatible with lighting or alarm systems
 Power characteristics: designed for low power consumption during standby
 Response: fast detection of moving heat sources such as humans
How to use
Install the MACLEAN MCE203 on a stable wall or ceiling surface at a height and orientation that provides clear coverage of the monitored area, avoiding direct exposure to heating vents or strong sunlight that could generate false triggers. Connect the sensor output to the lighting circuit, alarm input or automation controller according to the integration requirements and local electrical codes. After mounting and wiring, test the coverage by walking through the space to confirm detection zones and adjust position if necessary.
Usage recommendations
For optimal performance, mount the sensor at the manufacturer-recommended height and orient it to minimise blind spots. Keep the detection field clear of large stationary heat sources and avoid pointing the sensor directly at windows or HVAC outlets. Regularly check connections and test detection to ensure reliable operation in occupancy and security roles.
