Unlock the Full Power of Lightcloud Blue on Any Ceiling

The RAB ARM/LCB is a mounting bracket for LC Blue ceiling sensors, built for both indoor and outdoor use on low or high ceilings. It's especially useful in warehouses or industrial spaces where rafters, girders, or other structural obstructions block a sensor's sightline if mounted flush to the ceiling. The bracket lets you angle or offset the sensor for better coverage in these tricky layouts.

It mounts to a 1/2" knockout on a junction box, works with sensors configured for occupancy, vacancy, or daylight control via the Lightcloud Blue app, and now supports load switching up to 8A. Built from frosted, shatter-resistant polycarbonate, it's UL Listed and backed by RAB's 5-year warranty.

Compatible sensors: MVSW50/LCB, PIRW12/LCB, PIRW40/LCB. 

Mount your ceiling sensor exactly where it needs to be, even when the ceiling itself gets in the way.

• Clears the Obstruction: Drops the sensor below beams, ductwork, or racking that would otherwise block its view.
• Fits Your Sensor: Compatible with PIRW12/LCB, PIRW40/LCB, and MVSW50/LCB.
• No Special Tools: Mounts to a standard 1/2" knockout on any junction box.
