I have a situation with obstructed construction; solid 18-inch steel beams with pockets being over 320 square feet. The beams are 10-ft on center.
The area is part of a warehouse, Ordinary Hazard Group 2.
Can I space my branch lines 14-ft apart if I'm protecting every pocket?
Sprinklers are 5-ft (on center) from beam and 14-ft to the next branch line.
Thanks in advance!
