NFPA 25 does not require the inspection of sprinklers in concealed spaces, so 
that should not be an issue.

Subject: Attic/Concealed space access to sprinkler heads

I have a project intended to be fully sprinkled with a combustible attic that 
tapers from 2' to 4 ' without being filled to within 2 inches of the deck with 
insulation. So I am planning on a dry pipe system with standard heads as the 
design of the attic does not allow the effective use of special application 
attic sprinklers.

The questions are: whether inspection access is required to be provided, is it 
prudent to do so at the heads, or can the locations just be noted on the gypsum 
mounted to the bottom chord of the open web trusses.

TIA
