I have an AHJ who is telling me that I need to rotate my design area length 90 degrees to account for there not being enough sprinklers per line on the branches. This would give me a design area that is perpendicular rather then parallel per 14.4.4.1.11. Section 14.4.4.1.1.3 states, “In systems having branch lines with an insufficient number of sprinklers to fulfill the 1.2 requirement, the design area shall be extended to include sprinklers on adjacent branch lines supplied by the same cross main.” I was taught, and therefore I have always understood this to mean that in a situation where there are not enough sprinklers per line you include additional sprinklers up to the point that your design are is fulfilled, i.e. add sprinklers until I reach 1500 sf, not until I have created a perpendicular area of 46 + ft. Is this the same understanding that everyone else has?
