That's the thing Steve, I don't think there's a way to determine if the overhead sprinklers will reach the lowest rack levels (without performing expensive tests, lol)... So then the answer is to install ESFR sprinklers throughout.
Thanks Steve and say hi to the old gang for Stephanie and I!

Do you continue installing ESFR sprinklers under each level or can you install control mode sprinkler under the catwalks while the ESFR's at the ceiling protect the commodity?? I did look up the archives and a few people have asked similar questions over the years, but I don't see an answer... NFPA 13, 2007 ed. Thank you in advance!
