I am designing an In-rack sprinkler system in an industrial building that has 4 existing Automatic Sprinkler Systems that are wet and configured as a grid. They are located directly under the collector grid main. Is there anything in NFPA-13 that will not allow me to connect the in-rack supply from an adjoining Sprinkler System. The in racks are double row racks and running parallel with the grid lines, so when I calculate the ceiling sprinklers directly above the racks and calculate the in racks sprinklers, I will be flowing from two different risers, if so would I still need to balance the two? It is economically advantageous not to connect at the base of the riser or to the Supply main of the directly overhead system.
