300.3c Read FPN See 725.(A) for class 2&3 circuit conductors if control wires not class 1.

Just remember you made the "low voltage" signalling circuit a 725 class 1 when you put it in there with the line voltage so you pretty much treat it like line voltage.

Difinitions Class 1 725.1. Class 2 & 3 725.41
Putting a Class 2 circuit in with a line voltage Does Not make it a class 1. Read 725.55 Thats the Reason for the FPN.

I don't see any reason why you can't treat a class 2 circuit as a class 1 if you wire it all to class 1 standards. All the voltage/current limits I see in the definitions are upper limits, not lower ones.
If anything in that circuit is not appropriate for a class 1 you can't do it.

752.52 A exception #2 I belive is what you are referring to. But even there it states you must comply with Part 2 Class 1 circuits.
