Where longitudinal bracing is provided for branch lines, the lateral bracing ZOI of grid mains does not have to include those lines per §9.3.5.9.6 (2016 edition).
Steve L. From: George Medina Jr. <[email protected]> Sent: Thursday, March 21, 2024 2:55 PM To: Discussion List On Issues Relating To Automatic Fire Sprinklers <[email protected]> Subject: [Sprinklerforum] EQB and Zone Of Influence I have a job where I have grid system where there is 6" grid mains and 2½" grid lines. In order to lessen the weight in the zone of influence of the 6" grid mains I have included additional longitudinal bracing on the 2½" grid lines. Is it acceptable to exclude the Zone of Influence of the Longitudinally braced 2½" Grid lines from the Zone Of Influence of the 6" Grid Mains? Does NFPA-13 address this scenario?
