CM 10 Passive Infrared Extended Range Ceiling Mount Occupancy Sensor

Our review of the CM 10 Passive Infrared Extended Range Ceiling Mount Occupancy Sensor finds it best for installers and facility managers who need a reliable, ceiling-mounted motion sensor with wide 360o coverage. The single biggest reason to buy is its extended range and dependable PIR detection that requires no field calibration, which simplifies installation in corridors, garages, and open rooms. The review focuses on real-world usability: ease of installation, clear wiring for 120-277 V fixtures, and practical programmable controls make it a straightforward choice for commercial and residential use.

Key Features

• 360o PIR Detection: Provides full ceiling coverage ideal for walking motion and T-shaped intersections in corridors where wall mounting is impractical.
• Extended Range: Detects motion across a generous area so it works well in large garages and open common spaces without extra devices.
• No Field Calibration: Ready to use out of the box with no sensitivity adjustments required, saving time during installation and commissioning.
• Push-button Programmable: Simple push-button controls let a technician set time delays and behavior without specialized tools.
• Excellent RF Immunity: Designed to resist radio frequency interference, improving reliability in environments with wireless equipment.
• Test Mode and Adjustable Delays: Built-in test mode and adjustable time delays make final setup and troubleshooting quick and predictable.

Who It's For

The CM 10 suits electricians, maintenance staff, and contractors installing ceiling-mounted occupancy sensors in corridors, garages, warehouses, and retail backrooms where 360o coverage and extended range matter. It is especially useful when a wall-mounted sensor cannot see cross traffic or when a single sensor must cover a broad area of walking motion.

This sensor is less appropriate for projects that require occupancy sensing tied to advanced building automation protocols or dimming control not implied by the product description. If you need networked smart features or sensitivity tuning at the field level, look for a different model with those capabilities.
