1947?! Wow. Maybe it was a benchmark the writers decided to set way back when? Maybe in the interest of "restoring systems quickly"?
Tom FGOL In my 1947 edition of NFPA it states the exact wording with no reasoning. The farthest back for ROC and ROP on NFPA website is 2002. Thanks, Russell Rewis Brown Automatic Sprinklers, Inc. 107C Hemlock Street Valdosta, Georgia 31601 229-244-8130 In NFPA 13, 1974 5-2.7.2 my earliest edition, has the 30 min. requirement, so if you want the reason they wrote it this way, you'll need to explore the committee ROP and ROC for earlier editions.
