Thanks, Definitely going to have a separate riser, I do not see any need to balance the two since they are both from different systems. what do you think?
Thanks for the input George Medina Jr. -----Original Message----- From: Todd Williams <[email protected]> To: sprinklerforum <[email protected]> Sent: Mon, May 21, 2012 1:57 pm Subject: Re: In Rack Sprinkler Supply There is nothing I have seen that says in-racks must have a dedicated riser, nly that they must be separately controlled. I think that arrangement would be cceptable, but I would install a control valve on the feed to the in-racks. ake a look at the diagrams in 8.16.1.6 in the Handbook. t 04:34 PM 5/21/2012, you wrote: I am designing an In-rack sprinkler system in an industrial building that has 4 xisting Automatic Sprinkler Systems that are wet and configured as a grid. They re located directly under the collector grid main. Is there anything in FPA-13 that will not allow me to connect the in-rack supply from an adjoining prinkler System. The in racks are double row racks and running parallel with he grid lines, so when I calculate the ceiling sprinklers directly above the acks and calculate the in racks sprinklers, I will be flowing from two ifferent risers, if so would I still need to balance the two? It is conomically advantageous not to connect at the base of the riser or to the upply main of the directly overhead system.
