According to NFPA 13 2007 8.6.3.2.3, In a situation with angled and irregular walls, you are allowed to go 75% of the maximum distance between sprinklers provided the maximum perpendicular distance is not exceeded. My question is how do you actually figure the square footage required to do a calculation? For instance, if you look at the diagram in the appendix , what would be the square footage of that sprinkler?
Would it be (2 x 7'6) x (2 x 11.25)? Or (2 x 7'-6") x (11.25' x 1.333) or just (2 x 7'6) x (2 x 7'6)?
