Sprinklers aren't "rated" for building height in and of themselves, as
the maximum height it depends on a lot of factors. So long as the
sprinklers are listed for the NFPA 13 design you are using, that's all
you need. For example, K14 ESFRs are limited to 32 ft. buildings at 50
psi, but can go to 40 ft. at 75 psi.

Forum,
I just got back some comments from the local AHJ on a project we are doing
and he's asking me to verify that the heads we are using are rated for
ceilings over 30'. I've spoke with the manufacturer and he said he doesn't
have anything on min./max. ceiling heights. If memory serves me isn't 50'
somewhere in NFPA? Any help would be appreciated.
