I would offer that there is no exception in the NFPA 14 standard for protection of piping serving horizontal exits and as you noted, those are different from the intermediate ones. The distinction exists in both the standard and the IBC, which also requires the protection of piping. Additionally, many fire departments aren't interested in those intermediates because they train so rigidly on FF operations staged in stairwells and vestibules. Being a CA-based company, we're used to restrictive code amendments and fire department ordinances that tweak the standards, so I've encountered more restrictive (i.e., yes the intermediates are required AND they must be wrapped in fire-rated construction) and more relaxed (intermediate standpipes aren't required at all) policies.
The foregoing is my opinion only and does not represent NFPA or the NFPA 14 Technical Committee, nor intended to serve as an interpretation of the standard.

Is that intended to apply to standpipes near horizontal exits also? If they were closer to the stairs, they would not be needed. So technically they are there in order to meet travel distance requirements... so, no fire rated enclosure required?
