Hitting a wall how? I Thing The AHJ is on point, unless there's something else
to the story.

Subject: Existing sprinklers
We have a building that was built about 30 years ago the sprinkler system
was designed to NFPA 231C with a ceiling density of 0.45 gpm over 2000
square feet. There is good water pressure and the sprinkler heads are 5.6K
and 286°F
We have a new tenant and they require 0.45/2000 and the AHJ says the heads
need to be changed to 11.2K because the density is above 0.34, I said that
NFPA 25 (2008ed) section 4.1.6 Addressing Changes in Hazard, indicates that
the system needs to be evaluated and if the system provides the required
protection then no changes are required.
Comments please I seem to be hitting a wall.
Thank you
