No it is light hazard and this was his response after I argued the point..... "The most demanding design area is not the T-Bar ceiling, but the attic. The Code States "the system area of operation shall be permitted." So the system area of operation is the attic at 18'. You can reduce to 18', but not to 10'. "
That being said I calculated the attic because its sloped so the design area needed to be increased 30% so I did that and then proceeded to reduce it 40% because the attic at its peak is 9' above tee bar...
