George, I believe the only way you can run cpvc supplying pendants in a attic that requires sprinklers is by using "attic" sprinklers fed from steel pipe and then the cpvc pipe will need to be thermally (fire not cold) protected with insulation 6" above and 12" to each side of the pipe. Check the Tyco data sheets though.
