NFPA 13 2007 8.15.15.3 allows old style sprinklers "where construction features or other special conditions require unique water distribution."
Has anyone come across such a situation? For example: I have a building where there is some structural steel passing through a non-combustible, non-accessible, mechanical shaft (that was previously un-sprinklered). For whatever reason, they feel like it will be extremely difficult to get fire-proofing onto the steel, so the architect suggested using old-style sprinklers to protect the roof structure and steel below (since they spray up and down). It was my understanding that standard spray sprinklers are used now specifically because they work better at protecting the structure above them (and better at attacking the fire), but I wanted to double check. Any thoughts? Thanks!
