In a large attic that is fully protected with a fire sprinkler system approved with exposed CPVC piping? If so any special conditions
The cvpc can be used to protect the rooms/area below the attic. No special requirements except a sprinkler attic.
The cvpc cannot be used to feed the sprinklers protecting the attic.
Does that answer your question??
The best thing to get, since there are different manufactures, is the listing and installation guide for the cvpc.
It will tell you what the pipe has been tested for as in where it can be used exposed and where it can’t, plus other restrictions
Make sure you get the most up to date
I am going to say yes you can.
Taken from the Tyco Blazemaster Installation Instructions &Technical Handbook that Cda referred us to.

Another cost reduction is the Listing of BLAZEMASTER CPVC for use in attic spaces to feed the wet system Specific Application Attic Sprinklers for Protecting Attics, as well as to feed the wet system sprinklers below the ceiling. Traditionally, BLAZEMASTER CPVC has been used on the lower floors in the joist space above a ceiling that do not require sprinklers. The cost of using CPVC on those floors can now be translated to the upper floor even if sprinklers are required in the attic.
