Ron: Thanks for the input. I don't have a copy of the NFPA 72 because it is out of my jurisdiction, I leave it to the fire marhall. I call this out on plan review often and have been told by EE's that the 72 has a different elevation. Thanks for the correction.
Bob: I don't have the ANSI here at the house so I'll back this up on Monday, but I believe for a ceiling mount you are permitted to go up to the ceiling as long as it is not more than 30(?) feet A.F.F.
