Sensor Switch CM 10 Ceiling-Mount PIR Occupancy Sensor

The Sensor Switch CM 10 is a 360° ceiling-mounted passive infrared (PIR) occupancy sensor engineered to detect walking motion across an extended range for reliable, hands-free lighting control.

The CM 10 merges extended-range PIR detection with a compact, ceiling-mounted design to monitor large open areas and corridor intersections from above. It’s designed for straightforward installation in standard fixtures and supports 120–277 V systems with wires supplied, making it a practical retrofit or new-install solution for commercial and institutional spaces that need automatic lighting control without visible wall devices.

How does the CM 10 detect motion from the ceiling?

The CM 10 uses passive infrared sensing tuned to recognize walking-style motion across a 360° field of view. Its circular coverage pattern is optimized for overhead placement, so it sees activity in multiple directions without needing a wall-mounted sensor.

• PIR element detects thermal changes caused by moving people
• 360° detection pattern for complete overhead coverage
• Extended range suitable for larger rooms and corridor intersections

What electrical systems and wiring does it support?

This sensor is compatible with fixtures and lighting systems operating from 120 to 277 volts; the unit ships with the necessary wires for direct connection. Its design accommodates common commercial voltage ranges so you can use it in a wide variety of building installations without extra adapters.

• Operates on 120–277 V lighting circuits
• Pre-wired with connection leads for quick installs
• Works with typical commercial and institutional fixtures

How configurable is the sensor for different spaces?

Programming is handled via push-button controls for straightforward setup of time delays and operational modes. There’s no field calibration or sensitivity tweaking required, so installers can configure the CM 10 quickly and move on to the next job.

• Push-button programming for time delays and modes
• Adjustable time-delay settings to reduce false-offs
• Built-in test mode to confirm coverage during installation

Will the CM 10 resist interference and false triggers?

Designed with excellent RF immunity, the CM 10 minimizes false activations from nearby radio frequency sources while maintaining reliable PIR detection. That makes it suitable for environments with wireless devices or electronic equipment without frequent nuisance switching.

• PIR detection with robust RF immunity
• Reduced false triggers in electronically noisy environments
• Stable operation across typical commercial settings

Who this is for: The Sensor Switch CM 10 is ideal for facility managers, electricians, and contractors who need a discreet, ceiling-mounted occupancy sensor for corridors, open office spaces, stairwells, and junctions where wall mounting isn’t practical. It suits retrofit projects and new installations that demand wide-area detection, simple push-button setup, and compatibility with 120–277 V lighting systems. If you want extended overhead coverage without field sensitivity adjustments and with built-in installer-friendly features like test mode and pre-wired leads, the CM 10 is a practical, dependable choice.
