Anthony- The wording in 8.6.4.1.1.3(b) points you to the “obstruction rules…”. I agree the choice of words can be confusing though because it almost makes it sound like all you have to do is follow figure 8.6.4.1.1.3(b)

Why is this code there if you still have to use the obstruction rules? I'm interested in knowing if I've been interpreting this wrong.

(NFPA13 / 2013) There’s got to be more to Fig 8.6.4.1.1.3(b) with regard to ceiling height changes. For example, what if the head (blue arrow) is only a foot off the ceiling height change? I assume 8.6.5.1.2 would have to come into play as well?
