NFPA 13 maximum area protected per riser
NFPA 13 maximum area protected per riser
(OP)
Hi! I'm new to design on fire protection. These are my questions regarding the maximum floor area per riser.
1. If the building I'm about to design has multiple floors, is the maximum floor area accumulated on all floor?
2. If I exceed the maximum area per riser do I need a new fire pump for that? 1 pump per riser?
Thank you!

If your building is more than two stories in height there must be a separate riser for each floor at a minimum. Otherwise you may have a system protect two floors if the combined area is less than the maximum allowed for the hazard.

We are on NFPA 13-2016 in NY.
It's 52,000SF/floor.
In 2016 they added some stuff about more than two floors. (I just saw this - hence why I'm glad.)
I just looked at 2019 and it looks like they completely rearranged to standard. Can some one point out where is area requirement is in 13-2019?
