I believe that the intent was to let you know that when the occupancy exceeded 1000, more standpipe protection was required based upon that fact alone. Just as 905.3.4 allows class II & III standpipes under certain conditions for stages. Your correct there is no class three requirement in 905.3 unless its unsprinklered in which case a class I standpipe is required. But when your reading code you can't just stop because you think you've found the only thing you need. Read all of 905, see what other sections say about A occupancies, and which apply to your situation.
Is your occupancy over 1000? No? then 905.5.1 doesn't apply. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.
