I have a situation where I have a stepped obstruction against a wall. The occupancy is Light Hazard. The primary ceiling is 9'. There is a 4' wide soffit against a wall that is 1' lower. Under that soffit, there is one that is 1'-10" wide that sticks down an additional 1'. I presently have a sprinkler in the high area that is 3'-2" from the edge of the higher soffit.
A sprinkler is going to be required under the under the first soffit because the sprinkler in the high area cannot protect underneath it based on section 8.6.5.1.2(1) (NFPA 13 - 2002). However, the sprinkler in the high area can protect under the lower soffit per section 8.6.5.1.2(3). Can I install a sprinkler under the upper soffit and call it a day?
