My assumption is that the special application sprinklers you're talking about are the Tyco attic series sprinklers. Their 28 or so page MDS pretty much covers every situation, along with the literature from Blazemaster, Spears, Victaulic, (insert preferred CPVC supplier here) regarding listed piping installations for combustible spaces.
But, basically, yes - or at least that's my take on it. You're pretty much looking at the combination of the listing of the two installation concepts of the CPVC literature and the Tyco Attic head series. If what you have is still in question, odds are you'd be better off contacting the manufacturer you're using and explain the situation and get their blessing in writing.

There is an attic sprinkler system also. If we supply the attic sprinklers from the wet system covering the third floor, it appears we must use special application sprinklers and these will protect the plastic pipe in the attic. However we have a freezing possibility in the attic and will have to run a dry system. Assuming the plastic is insulated with lay in insulation, can we use standard sprinklers in the attic sprinkler system or will we have to use the special application sprinklers anyway. The issue is of course cost! Thanks in advance. Geoffrey H. Dyce Operations Manager/NICET IV DELTA Fire Sprinklers, Inc.
