I know that per 1023.5 of the code, there are no penetrations allowed in an interior exit stairway except for the items listed that serve the stair. Per the exception though, membrane penetrations are allowed on the outside of the enclosure. Are you then allowed to run items inside the wall that are not serving the stair? For instance a line-set serving a room located below the rated stair?
