Because section 8.4.7 replies to large drop sprinklers only. Thus, 8.4.7.2 is a subsection to the large drop requirements only.

(2007) Calls for steel pipe used in Dry Pipe and Pre-action systems to be internally galvanized, the handbook adds additional information saying this only applies to systems with Large Drop sprinklers. How can I use this "added text" to explain to an AHJ that says NFPA requires galvanized pipe for any type of a dry system?
