Per NFPA 13R (07ed) 6.8.1.5.3.6(C) you need to be at least 3ft above to not have to build a soffit. Can install the heads on another wall and eliminate the obstruction all together?

It’s not protected in either scenario.

Is this acceptable or does a soffit need to be built above the cabinet to bring the face of the sprinkler flush with the face of the cabinet? *Brian Harris, CET* BVS Systems Inc.
