Once the water is past the inspector's test valve, or main drain valve, it is beyond the sprinkler system so the material choice is not limited.

I agree with Paul, It is a drain, as long as it still routes the water to the outside or floor drain, it is not a problem.

It looks like the only thing regulated by NFPA 13 for drain piping regarding material type is corrosion resistance when buried underground.

8.16.2.6.3: "Where drain pipes are buried underground, approved corrosion-resistant pipe shall be used."

Drain piping also does not need to be listed (6.1.1.5), which further supports the notion that plastic is okay.

CPVC piping must not be exposed to sunlight for long periods of time per the manufacturers data sheet. so as long as the drain piping is located inside, you should be ok. The piece sticking through the exterior wall should be galvanized in my opinion.
