Two 2" branch lines were run parallel to and 18" down from the peak. EC horizontal sidewalls were aimed parallel to the slope. A baffle board was placed between the two rows of heads. How do you arrive at the conclusion that this offers little or no protection? Explain yourself. Don't condemn when you don't have the whole story.

I suggested the attic sprinklers in response to the suggestion for sidewall sprinklers at the peak. My only intent was to suggest that, if you're going to go beyond the defined limits of a type of sprinkler, you should at least start with a type that at least is intended to work in a similar application. I can't say that the attic sprinklers will work, but if they won't, sidewall sprinklers at the peak certainly won't work either.
