I've wondered for a long time if Section 220.127.116.11.5.1 of NFPA 13 (2019 edition) in a way allows for unsprinklered combustible concealed spaces, like a large wood canopy, if the remote operating adjacent to the area is increased to 3000 sf and there's a fire barrier between the two areas?
Is this an acceptable approach?
I'm assuming the barrier's rated must be equivalent to the required water supply duration, if so.
Thanks in advance.
