True, for 2016 it's "Installed with the deflectors at or above the bottom of the structural member to a maximum of 22 in. (550 mm) below the ceiling/roof deck where the sprinkler is installed in conformance with 8.6.5.1.2" my reason for commenting was item 2 allows 22" even if it's above the bottom of the structural member if the obstruction rules can be followed which wasn't how I had read your comment but I may have been mistaken.

All the sections I note are from the '16 edition of NFPA 13 Obstructed construction per §3. 7. 1, §A. 3. 7. 1(1), as you have concrete beams, spaced between 3' and 7½" apart. ZjQcmQRYFpfptBannerStart This Message Is From an Untrusted Sender You have not previously corresponded with this sender. ZjQcmQRYFpfptBannerEnd Jackie, I echo the thoughts of Anthony, Matt, and my good friend Cliff. All the sections I note are from the '16 edition of NFPA 13 * Obstructed construction per §3.7.1, §A.3.7.1(1), as you have concrete beams, spaced between 3' and 7½" apart. * Sprinklers required in each bay, per §8.6.4.1.2(3), as it's not possible to reach the 22" maximum in (1) or (2) as the beam depth is 24" Hope that lines up with what others have to say. And, except for the section numbers this is fairly unchanged in the '22 edition. sincerely, Ken Wagoner, SET Parsley Consulting 500 West Mechanic Street Harrisonville, Missouri 64701-2235 Phone: (760) 745-6181 Visit the website<https://urldefense.com/v3/__https://linkprotect.cudasvc.com/url?a=http*3a*2f*2fwww.parsleyconsulting.com*2f&c=E,1,Y5zKJKPEh1mBEBqSR-VE9cUKl5y-eyP8BpvmE_5j9ZqW2eJbNphYzrCMBZ-2YuX6d-RRkHI4gQ1FV-cvOeCfRC58uZS9NiToZv2mx7909oCqLvCW_n5hDHeK&typo=1__;JSUlJQ!!FaxH778!YFCUu-j6odPrO_X-MFMR8WKY_8xg-wufPwm_LbKuEFfCR6JMnCumBY8kS_LdFkJ8r0qgPptUttn45O4JDvdP$> This message is for the named person's use only.
