Sensor Switch CMRB 6 High Bay PIR Occupancy Sensor

The Sensor Switch CMRB 6 High Bay is a fixture-mounted passive infrared (PIR) occupancy sensor engineered to control line-voltage high-bay fixtures up to 45 feet without a separate power pack.

Installed directly on or near high-bay lighting fixtures, this CMRB 6 model provides 360° occupancy detection optimized for warehouse, gymnasium, and industrial ceiling heights. Its 15–20 ft. radial coverage pattern is designed to overlap the lighted area of a typical high-bay fixture, enabling reliable on/off switching via an internal relay while remaining compatible with a wide range of lamp types.

How does the CMRB 6 detect people at high mounting heights?

The CMRB 6 uses passive infrared (PIR) sensing to detect changes in thermal signatures across its 360° field. At mounting heights up to 45 ft., the sensor’s coverage pattern focuses detection radially 15–20 ft. from the fixture, which matches the illuminated footprint of many high-bay luminaires.

• PIR technology detects motion by sensing body heat differences.
• 360° pattern ensures surrounding area coverage beneath the fixture.
• Optimized for tall ceilings (up to 45 ft.) with a radial detection range.

Will it work with my lamps and ballasts?

The CMRB 6 is designed to switch line-voltage loads directly and is compatible with common lamp and ballast types, removing the need for a separate relay or power pack. It supports electronic and magnetic ballasts, CFLs, LED drivers, and incandescent lamps, giving flexibility across many lighting systems.

• No minimum load requirement—works with low-wattage LED and CFL fixtures.
• Interchangeable hot and load wiring simplifies installation.
• Self-contained relay lets it control the fixture directly on line voltage.

How do I set it up and customize behavior?

Programming is done via push-button controls on the sensor, allowing installers to tune time delays and sensitivity without special tools. The simple interface streamlines on-site commissioning and helps adapt the sensor to different room sizes and activity patterns.

• Push-button programmable settings for time-out and sensitivity.
• Quick wiring with interchangeable hot/load conductors reduces installation errors.
• Self-contained design eliminates separate power pack wiring complexity.

What maintenance or limitations should I expect?

The CMRB 6 is low-maintenance and designed for stable operation in commercial environments, but proper placement and periodic cleaning of the sensor lens will ensure consistent detection. Avoid placing the sensor where strong drafts, heaters, or reflective surfaces could mask thermal changes.

• Occasional lens cleaning maintains PIR sensitivity.
• Not intended for direct outdoor exposure—use in covered indoor high-bay areas.
• Mount at recommended heights for accurate 15–20 ft. radial coverage.

Who is this for? Facility managers, lighting contractors, and operations teams who want a simple, fixture-mounted occupancy control for tall indoor spaces will benefit from the Sensor Switch CMRB 6 High Bay. It’s a practical choice for warehouses, manufacturing floors, gymnasiums, and other high-ceiling environments where direct line-voltage switching, broad compatibility with lamps and ballasts, and a compact, self-contained sensor are priorities.
