12Vdc In the Wall

[Kurta]

I have an application feeding 12Vdc from above the ceiling. Power supply is mounted in a 4 sq. box in the ceiling. Feeding the 12Vdc from the power supply inside a sheet rock wall approximately 6 feet to a ribbon (tape light) surface mounted on the sheet rock. The building is an assisted living facility. (Commercial / healthcare).

Does the 12Vdc conductor need to be inside a wireway /conduit /flex? Or is a PVC jacketed
two conductor cable sufficient?

is it a class 2 circuit?

What immediately comes to mind is that the wire you are using needs to be listed as CL3 at minimum (this allows for it to be installed within a wall) , next would be if it also needs to be Plenum rated if the airspace above drop ceiling is for return air to air handler.
