Sensor Switch CMR 10 Ceiling-Mount PIR Occupancy Sensor

The Sensor Switch CMR 10 is a ceiling-mounted passive infrared (PIR) occupancy sensor that automatically controls line-voltage lighting for commercial spaces with a 360° detection pattern and adjustable time delay.

The CMR 10 Contractor Select sensor is built for straightforward lighting automation in offices, retail areas, and other commercial interiors. It mounts to standard ceiling grids or junction boxes, senses large motion across a wide cone, and switches line-voltage lighting without an external power pack. Push-button programming, a visible green LED, and CSA certification make it a practical choice for facility managers and electricians who need a durable, code-ready occupancy control.

How wide and far does the CMR 10 detect motion?

The CMR 10 uses a 360° conical detection pattern optimized for large motion like walking. When installed at a typical 9 ft ceiling height, it covers about a 24 ft radial range, making it effective for private offices, conference rooms, and small open areas.

• 360° PIR coverage for all-around sensing
• Optimized for large motion detection (walking)
• Approximately 24 ft radius at 9 ft mount height
• Effective from 7 to 15 ft ceiling heights

How do you install and program the sensor?

Installation is designed to be quick for contractors: the sensor fits ceiling tiles, metal grid systems, 3.5" octagon boxes, or single-gang handy boxes and includes mounting hardware. Programming is done using simple push-button controls and a green LED indicator to confirm operation; no separate power pack is required because the device switches line voltage directly.

• Includes mounting hardware for various ceiling types
• Fits standard junction boxes and ceiling grids
• Push-button programming with LED feedback
• Self-contained relay — no external power pack needed

What timing, durability, and safety features does it offer?

The CMR 10 provides a user-selectable time delay from 30 seconds to 20 minutes to match occupant behavior and energy goals. It is CSA certified for U.S. and Canadian safety standards, rated to operate between -10°C and 60°C, and carries a limited five-year warranty for commercial use.

• Adjustable time delay: 30 seconds to 20 minutes
• CSA certified for US and Canada
• Operating temperature range: -10°C to 60°C
• Compact footprint: 4.55" diameter, 1.55" depth

Can it integrate into existing lighting systems?

Yes — the CMR 10 is a line-voltage occupancy sensor that replaces a standard ceiling-mounted control and provides single-level switching via an internal relay. It is suitable for straightforward retrofit projects and new installs where simple on/off control is required without additional control wiring.

• Line-voltage compatibility; single relay output
• Ideal for retrofit or new ceiling-mounted installs
• Works with standard lighting loads compatible with relay switching
• No additional control modules needed for basic operation

Who is this for: The Sensor Switch CMR 10 is aimed at electricians, contractors, and facilities managers who need a reliable, easy-to-install occupancy sensor for private offices, meeting rooms, retail spaces, and small commercial zones. It fits projects that require simple, energy-conscious light control, rugged performance, and certification for commercial building codes — especially where ceiling-mounted detection and large-motion sensitivity are priorities.
