NFPA 13 2010: A.11.2.3.2.5 Where extended coverage sprinklers are used and the design area (after appropriate increases) is satisfied by five sprinklers, no additional increase is required. This is the annex material to 11.2.3.2.5 Dry Pipe and Double Interlock Preaction systems under the Density Area method section of calc procedures. I feel like there's another section pertinent to the question but that was the one that came to hand. Mike Morey, SET Sprinkler Designer BMW Constructors, Inc.
