Looking at a typical mini storage facility.  At the 5' wide hallways (walls 
full height to concrete deck) they are looking to install a 3' wide 
soffit/ceiling down the middle of the hallway.  This will leave a 1' gap on 
each side of the hallway.  The soffit/ceiling will be approximately 24" below 
the upright fire sprinkler deflector that is running down the center of the 
hallway.  Since the soffit/ceiling (continuous obstruction) is less than 4' 
wide and greater than 18" below the fire sprinkler deflector, then am I correct 
in thinking that fire sprinklers are not required per NFPA 13 2013 8.5.5.3 to 
be installed at the soffit/ceiling?   

Thanks,
