not necessarily, read 517.30(B)(4) and look at the FPN diagrams 1 and 2 as I mentioned. Do you have a code book?don't you need one for every system?
It only combines these Branches in the fact that they are both Emergency branches, They are still two completely seperate systems with different functions. See 517.32 and 517.33 for the specifics.Originally posted by d6183:
what about 517-31 doesn't that combine life safety branch and critical branch or am i not reading that correctly?
