Ceiling PIR motion sensor MACLEAN MCE19 — ceiling-mounted passive infrared detector

Ceiling-mounted PIR motion sensor MACLEAN MCE19 — ceiling-mounted passive infrared detector is a compact ceiling sensor designed to detect human movement indoors by monitoring changes in infrared radiation. Intended for ceiling installation, it provides presence-based control for lighting, alarm inputs and automation systems. The device is suitable for corridors, offices, storage rooms and residential areas where automatic activation and energy efficiency are required.

Advantages

The MACLEAN MCE19 ceiling PIR motion sensor offers broad coverage from a ceiling position and simple surface mounting. Its passive infrared technology delivers reliable detection of walking and standing people without emitting signals, which makes it compatible with lighting circuits and alarm systems. The sensor’s unobtrusive design and compact dimensions reduce visual impact while enabling flexible placement in different indoor environments.

Suitable for

• Ceiling-mounted lighting control in corridors and hallways
• Occupancy detection in offices and meeting rooms
• Presence-based automation in storage rooms and utility spaces
• Residential rooms and common areas for energy-efficient lighting

Key specifications

• Type: Passive infrared (PIR) motion sensor for ceiling mounting
• Detection method: Changes in infrared radiation emitted by humans
• Mounting: Surface ceiling installation suitable for indoor use
• Application: Controls lighting, alarm inputs and automation systems based on presence
• Design: Compact, low-profile housing intended for unobtrusive ceiling placement

How to use

Install the sensor on a stable ceiling surface at the recommended height for optimal coverage, following local electrical regulations and safety standards. Connect the sensor to the lighting or automation circuit according to the wiring diagram supplied with the product, ensuring power is switched off during installation. After wiring, perform a functional test by walking through the coverage area to confirm reliable triggering and adjust position if needed. Use appropriate fixing screws and secure cable entries to maintain reliable operation.

Usage recommendations

For best performance, mount the sensor where the expected movement crosses the detection zones rather than directly toward the sensor. Avoid installing near strong heat sources, air vents or close to windows that could cause false triggers. Regularly check mounting and connections and clean the sensor cover to prevent dust build-up that might reduce sensitivity.
