Brian, Looks like you're quoting one I did about a month ago. Don't forget that with a roof slope of > 4 in 12 and if sprinklers installed where the dimension Perpendicular to the slope exceeds 8'-0" shall have a minimum pressure of 20PSI. I try to avoid that much pressure required and space my heads 8'-0" on center.

First thought was interstitial heads under it but then got to thinking, since there's not another floor above wouldn't attic or upright heads be acceptable instead. I guess I'm wondering if having a floor above is what drives interstitial heads?
