Bill, As ‘unconventional’ as this sounds, you could put another sidewall under the soffit instead of the pendant and have it cover the area under the soffit on both sides of the room. Never done this before and it would look ‘weird’ but per code, it would work without adding the 3rd sprinkler in the room.

A wise man once said, "a question well asked is a problem half solved", so I'll do my best. I have a bedroom in a 13R occupancy which measures 14'x16'. There is a 24"wide x 18" deep soffit around the perimeter of the room. I have a residential horizontal sidewall head in the soffit 12" below the ceiling along the 14' wall and a pendent head in the soffit just below. Here is the question: The distance from the sidewall head to the soffit at the far end of the room is 12'. Since I am 6" above the bottom of the soffit, the minimum distance required by 8.10.7.1.3 (2010) is 13'. Do I need another head under the far end soffit? It seems ridiculous, but what do you think? Thanks much. Bill Menster
