    See Annex D for acceptable test methods. Most commonly, it's the AHJ walking around and saying "push it up in this area" or "a little too loud here". And that's fine by NFPA 72.

    I'll repeat my earlier objection; we don't know the OP is dealing with multiple dwellings. We shouldn't bother arguing this point until we have this information.
