Starting to rethink this after reading the entire manual on the Tyco site. This is a single story wood frame building, designed to NFPA-13. The way I'm reading it the piping above the ceiling is considered exposed and would have to be attached directly to the ceiling, I was originally planning on running the branchlines perpendicular to the framing and dropping pendents down into the ceiling, I guess this is a no-no?

Tell me how it falls into any R occupancy. I can see him granting a variance to 13 that allows omission of attic sprinklers if the design goal is life-safety only, but he's taking a big risk. My read is that daycare, except in that one special case where it's classified as an E, is a B occupancy and if configured properly not need a system at all. Not endorsing one thing over the other, just reading code. And how have you been?
