BUT (A) Where a vertical change in ceiling elevation within the area of coverage of the sprinkler creates a distance of more than 36 in. (914 mm) between the upper ceiling and the sprinkler deflector, a vertical plane extending down from the ceiling at the change in elevation shall be considered a wall for the purpose of sprinkler spacing as shown in Figure 8.6.4.1.1.3(A).
According to the new rule I believe that we cannot use the obstruction rules. Greg McGahan Operations Manager Living Water Fire Protection 1160 McKenzie Road P.O.

Of course the "soffit" is about 1'-9" wide. My thoughts are that a head is required due to the difference in elevation being greater than 3'-0". Any other thoughts?
