In the same situation with a fan less than 8' from walls I was instructed to use only one head per 2002 8.10.7.2.1.3, the four times rule I think, since the residential sidewall could sprinkle both sides, above and below, of the fan obstruction. So I did what I was told.

In regards to residential sidewalls, section 8.10.7.1.2 (02) says not to install residential sidewalls within 8' of a light "or similar obstructions." It doesn't provide any exceptions, such as the light being only 4" deep and the sidewall installed 6" down from the ceiling. It simply says you can't do it. Is a soffit along the wall opposite the sidewall considered a "similar obstruction"? I have a project where a 24" deep soffit is installed along 1 wall of the bedroom and along 1 wall of the living area (for ductwork). Disregarding the soffits, sidewalls would work wonderfully. If I consider the soffit a "similar obstruction", that pretty much eliminates the use of sidewalls. Am I missing something? Am I misinterpreting the intent of 8.10.7.1.2?
