there is another logical conclusion: that it is allowed for a dry system but the N/A under hose stream should match the other lines requiring 500 gpm. Without substantiation, one should be conservative and not apply it until NFPA fixes it.
Lo and behold it has been fixed by the 2010 ed. It IS allowed to be used for dry pipe and a 500 gpm hose allowance is required. Moral of the story: Look before you leap. Anyone have a chute I can borrow? Moving forward with that TIA.
