IPA: Could not disagree more strenuously, though I really like your beer.
How many sprinklers are we calculating in this compartment? How many do we reasonably expect to operate in case of a fire? It was described that the beams are only 6" deep; combustion byproduct will move pretty efficiently over those bumps and there is no way to be sure if sprinklers would operate over the fire or if they would skip to the other side of the room. There are potentially 13 sprinklers in the room and 4 or 5 or more could easily operate, none of which would be flowing at the designed pressure or flow rate. I think it's a much better approach to use sprinklers on the beams as discussed, or sidewalls, and protect the room with the fewest number of sprinklers that comply with the design criteria, for reasons of aesthetics, cost-efficiency and hydraulics.

Also, when you get into these high dollar luxury homes with beams, slopes, fireplaces in every room etc.. aesthetics plays a very important role and the homeowner will usually want a ton of flat plate concealed sprinklers VS. four 'uglies' sticking out of the beams. I can't say I'd blame them when forking over large amounts of money just to have the ugliest sprinklers on the market installed in the most conspicuous places in the most extravagant rooms in the house.....
