Benefits
- Maximize daylight savings: Automatic dimming with Dim-to-Off capability reduces run time and energy costs in daylit bays.
- One head, many spaces: Swap lenses (#6, #10, #50, #9) to match open areas, aisles, low-bay rooms, or small-motion zones.
- Fast, bracket-free mounting: Integrated snap-lock chase nipple installs through a 1/2" KO for quick, secure attachment.
- Simple setup & robust memory: Push-button programming, visible test mode, and non-volatile settings streamline commissioning.
Key Features
- PIR detection: 100% digital with excellent RF immunity
- Photocontrol modes: Inhibit, on/off switching, and automatic dimming & switching (ADC)
- Programmable delays: 30 s–30 min occupancy delay; selectable Dim-to-Off delay
- Reversible hot/load leads: Helps eliminate wiring reversal errors
- MVOLT/HVOLT choices: 120–277 VAC standard; 347–480 VAC options
- 42" leads: Extra reach for fixture wiring (42L)

Application Examples
- High-bay warehouses and distribution aisles (use #6 or #50 lenses)
- Manufacturing bays and loading docks
- Gymnasiums, recreation centers, and big-box retail
- Low-bay rooms and small-motion areas (use #10 or #9 lenses)
Installation Tips
- Mount through a 1/2" knockout; the snap-lock chase nipple secures the sensor—no extra bracket required.
- Choose the lens for the space: #6 (15–45 ft high-mount 360°), #50 (aisleway), #10 (7–15 ft low-mount 360°), #9 (small-motion).
- Wire 0–10V control per driver class; dimming common may be pink per NEC 410.69 (2020).
- Use push-button test mode for walk testing; then set occupancy delay and Dim-to-Off as required.
- Apply masking labels (with #6 or #50 lenses) to tailor end-of-aisle or center-of-aisle coverage.
Frequently Asked Questions
What does “ADC” mean on this model?
ADC indicates an integrated photocell that automatically dims lights based on daylight and can switch them off (Dim-to-Off) when sufficient daylight is present.
Does this include a lens, and can I change it later?
LSXR uses interchangeable lenses. You can select high-mount 360°, low-mount 360°, aisleway, or small-motion lenses and swap them in the field as needed.
What is the factory default time delay?
The occupancy time delay is set to 10 minutes from the factory and can be adjusted from 30 seconds to 30 minutes using the push button.
Will it work on 347–480 VAC systems?
Yes—HVOLT versions are available for 347–480 VAC applications. The standard unit is MVOLT (120–277 VAC).
How do I tune the Dim-to-Off behavior?
After setting the low trim (minimum dim), choose a Dim-to-Off delay from 0 seconds up to 20 minutes—or keep lights at the dim level without turning off.
Is special calibration needed for PIR sensitivity?
No. The sensor uses 100% digital PIR detection and does not require field calibration or sensitivity adjustments.
Where can I see coverage patterns?
The coverage diagrams for all lenses are illustrated (e.g., #6 high-mount 360° and #50 aisleway) to help match lenses to mounting height and layout.
