Sensor Switch Fixture-Mount PIR Occupancy Sensor

The SensorSwitch LSXR is a compact, line-voltage fixture-mount PIR occupancy sensor that automates commercial ceiling lighting with selectable high- or low-mount 360° coverage.

Designed for warehouses, corridors, offices, and gymnasiums, the LSXR delivers reliable passive infrared motion control at the fixture level. It mounts through a standard 1/2" knockout and works on MVOLT 120–277V systems, letting you replace or retrofit fixtures with an on-board motion sensor that reduces unnecessary run time and simplifies compliance with energy codes.

How does the LSXR detect people and where will it reach?

The LSXR uses a passive infrared (PIR) detector to sense large motion such as walking and turns lights on when occupancy is detected. Two interchangeable 360° lenses let you optimize coverage for ceiling height and room layout, so the sensor can be tuned to the installation environment.

• High-mount lens: 360° coverage up to approximately 45 ft for tall ceilings
• Low-mount lens: 360° coverage for 7–15 ft mounting heights
• Both lenses focus on large-motion detection—ideal for walking traffic in commercial spaces

What installation steps and wiring options are required?

Installation is designed to be fast and fixture-friendly: the sensor installs through a 1/2" knockout using a threaded chase nipple and secures with a snap-lock bracket that drops the lens 3" for clearance. Reversible hot/load wiring reduces wiring confusion and the compact housing fits tight fixture cavities.

• Mounts through 1/2" knockout with threaded chase nipple
• Snap-lock bracket drops lens 3" for fixture clearance
• Reversible hot/load wires simplify wiring during retrofit or new installs

How do I configure time delay, sensitivity, and testing?

Programming is digital and push-button based—no field PIR sensitivity calibration is required. Use the green LED and push buttons to set time delay (30 seconds to 30 minutes), apply a Sunlight Discount Factor, and enter Test Mode to verify coverage quickly during setup.

• Digital push-button programming with visible green LED indicator
• Time delay adjustable from 30 seconds up to 30 minutes (default 10 minutes)
• Test Mode for quick commissioning and confirmation of coverage

What certifications and physical specs should I expect?

The LSXR is compact and compliant with common commercial requirements: it measures 3.75"H × 2.50"W × 4.00"D, supports MVOLT 120–277 VAC, and is UL/cUL listed and Title 24 compliant. SensorSwitch backs the product with a five-year limited warranty for commercial installations.

• Compact footprint fits tight fixture spaces (3.75" × 2.50" × 4.00")
• Electrical: MVOLT 120–277 VAC; green LED status indicator
• Safety/standards: UL/cUL listed, Title 24 compliant, five-year limited warranty

Who is this for: The SensorSwitch LSXR is intended for electrical contractors, facility managers, and building owners who need a dependable, code-friendly fixture-mounted occupancy sensor for commercial indoor lighting. It’s especially useful when you want a compact, easy-to-install PIR solution with selectable coverage for different ceiling heights, simple push-button programming for rapid commissioning, and compatibility with MVOLT fixtures in warehouses, corridors, offices, and gym spaces.
