Steve is correct, George and if you're using the 2022 edition it's 18.5.9.6.

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).

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? 

 

 

Thank You,
