I read exactly what Mike said in those lines. If it supply path is to a sprinkler only it needs toe listed. If the supply path is to a sprinkler with plumbing along the way it needs to be listed and it also needs to comply with all the plumbing stuff.. If the path is solely to a plumbing fixture it needs only comply with plumbing stuff. You can't downgrade sprinkler requirements because the sprinklers come off a plumbing system any more than you can use non-potable pipe for the sprinklers that are supplied from the plumbing system with backflow protection or the like separation.
