If I understand you correctly, you just have a rack system with a
separate riser. Flow the rack and overhead sprinklers and let the
computer balance at the common junction point, wherever that is.

I have been asked to look at a location which has 2 rack levels of
pallets storage over garage doors in a loading dock area (existing).
The rack sprinklers are presently fed from the existing wet ceiling
system. Due to freeze ups and mechanical damage issues, they would
like to feed to rack sprinklers from an adjacent pre-action system. Is
there any issue with this and how would I handle the hydraulic
calculations?
