I have a couple of questions regarding NFPA 13 section 14.4.4.4.3 re
calcing sprinklers below obstructions, specifically referring to the
following phrase: "the water supply for one of the levels of
sprinklers shall be permitted to be omitted.....".
1. If you have more than one level of sprinklers below obstructions
(I have 2 on a project I am working on), does this mean you can only
eliminate one of the levels?
2. What constitutes a level? If you have ductwork at different
elevations, does that constitute one level?
