Dewayne, A short summary of my experience in this situation was the AHJ required the 3000 square feet if it was a 13 system. I did use 7psi head pressure to prove a minimum area density of 0.10/3000 vs. the residential head listing pressure required for the spacing within the 3,000 square feet. I hope someone else can give you better news. Kurt Kingston Commercial Fire Protection Inc. Mt Vernon, WA

The floors containing the residential units have a combustible concealed space that does not require sprinklers (8.15.1.2.6) but does not qualify for the 3000 sq ft exemption of 11.2.3.1.4 (4) for unsprinklered combustible concealed spaces. If I am using residential sprinklers, are they exempt from this rule because they are a specific application sprinkler and not an area/density or room design method?
