We did one of these about 5 years ago. Since all the heat will go to the peak that is where the sidewall sprinklers were installed. The sidewalls flowed water down the slope. The two pipe were adjacent to the center board. The pipe was painted to match the 100 year old wood beams. You can't even see them from the floor. That was our best solution. Even the architect liked it. FM accepted reluctantly.

The arrangement calls for branch lines to be symmetrical on each side, similar to NFPA 13 (2002) figure 8.6.4.1.3.1(b). I can meet the requirements for the steeply pitched roof section 8.6.4.1.3.3 and my "S" distance over the peak is good, but my straight line distance between sprinklers would be less than 6 ft and the deflectors would be effectively pointing the discharge towards the sprinkler on the opposite side. I think I have a problem here, but I am not sure how to address it. Any thoughts? Todd G.
