RAB RAB-LOS2500 – Frequently Asked Questions
1) Which RAB LOS2500 do I order for a 277V circuit versus a 120V circuit?
The LOS2500 is ordered as a voltage-specific part, not a field-selected one. LOS2500/120 is the 120V part and carries a 2000W load rating; LOS2500/277 is the 277V part and carries a 1500W load rating. Pick the one that matches the branch circuit feeding the lighting, and size the connected load under that part's wattage figure. On a mixed building where some areas run 277V and the rest 120V, you order both numbers rather than one sensor for everything.
2) Does the RAB LOS2500 occupancy sensor need a separate low voltage power pack?
No. The LOS2500 is a line voltage sensor, so it wires directly onto the 120V or 277V lighting circuit and switches the load itself. There's no class 2 wiring, no separate power pack, and no low voltage home run back to a controller. That is the practical difference from a low voltage sensor head, which cannot switch a load on its own and always needs a pack to do it.
3) How much load will a RAB LOS2500 switch on its own without a contactor?
Up to 2000W on the 120V version (LOS2500/120) and up to 1500W on the 277V version (LOS2500/277). Add up the connected fixture wattage on the circuit, including driver or ballast losses, and stay under that number. Above it you run the sensor into a lighting contactor or relay panel and let the sensor act as the pilot, rather than switching the full load through the sensor.
4) How much clearance do I need for the RAB LOS2500 sensor body?
Allow 4.8 inches of height for the sensor. That is the figure to check against plenum depth or the space behind a suspended ceiling tile when you're laying out the mounting location, and it matters more in a tight bar joist or hard lid condition than in an open warehouse ceiling.
5) Will the RAB LOS2500 look out of place on a finished office ceiling?
The sensor comes in white, which is the standard match for acoustic tile, painted gyp board ceilings, and most white device plates. For property managers standardizing across a floor or a portfolio, it's a single finish across both the 120V and 277V parts, so the sensors read the same whether the area is on 277V lighting or a 120V branch.
