I recently came across your 13, 13R Summary of differences sheet and was wondering if you could explain or site a section that explains how NFPA 13R cannot be considered “fully-sprinklered” for code purposes? Thank you in advance for any help.

For those under the International Building Code - the code benefits from the International Building Code each reference buildings "equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1". This section refers to an NFPA 13 system. Essentially, the code benefits that apply to a "fully-sprinklered building" or a "building equipped throughout with an automatic sprinkler system" only reference 903.3.1.1, which is an NFPA 13 system.

I'll also add that the intent of NFPA 13 is to protect property AND life, which is best achieved by providing sprinkler protection throughout all areas of a building, whereas the intent of 13R and 13D is life safety only.

I agree with Wayne.

One specific case of this is for dead-end corridors. When using an NFPA 13R system the dead-end corridor is limited to 20 feet (which is the same as no sprinkler protection) where it would be increased to 50 feet if using an NFPA 13 system.

A building protected by a NFPA13R system is considered to be fully sprinklered throughout:

If a building is protected by a NFPA 13R system it would be considered "fully sprinkled" to the extent of the exception heavy NFPA 13R coverage. NFPA 13R coverage is based on "occupant" life safety - time to escape and NOT for protection of the structure, though it can do that on a limited basis. Therein lies my resistance to allow NFPA 13R systems for most multifamily residential housing in my jurisdiction. Once the occupants are, hopefully, safely evacuated, there could be a fairly significant fire (attic, interstitial spaces, etc.) at which point the lives of firefighters would be in jeopardy fighting the fire. All lives matter to us including the firefighters. NFPA 13 systems provide the highest level of automatic fire sprinkler protection available. Our citizens, property owners, firefighters, etc. deserve that.

Water supply for NFPA13R system can be a combination of domestic demand and sprinkler demand . Therefor do not provide the same level of property protection as NFPA13 systems.
