Interior Hose Valve if Over 130-ft from Exterior?

3/18/2025

I am designing a wet pipe fire sprinkler system in a one story Group B occupancy (16-ft high). The building is about 90,000 sqft in area. The building will be fully sprinklered with two zone control valve assemblies.

The fire department is asking to add fire hose valve cabinets as the interior remote areas of the building are more than 130 feet from an exterior door, only citing that its required by IBC 2021.

Is this correct?

I can't find this requirement. Any help is appreciated.

Without knowing specifics of the building, they could be referencing:

905.4(2) for exit openings of a Horizontal Exit
905.4(6) for the remote portion of the building being more that 200' from a hose connection (the exterior door)

Unless the AHJ has amended their Building or Fire Code to be a more restrictive distance requirement.

Something that large would have egress distance issues without rated corridors (hence the Horizontal Exit requirement) and could also possibly fall into section 1004.8 "Concentrated business use area" for something like a call center and trigger additional requirements or the Arch provided a tradeoff "in lieu of" offering of additional hose valves for some variance to a horizontal distance requirement.

The 130'-0 requirement comes from NFPA 14 to the best of my knowledge. Not sure about requirements for a single-story building with no standpipe?

It is not uncommon for a local fire department to ask / request / mandate interior hose connections depending on the building layout and in consideration to locations of exterior hydrants.

Verify that these are Class I hose valves and they are to be piped separately from the sprinkler systems.

It appears the distance (130') is coming from the requirements of hose reach from an exit (horizontal exit or exit passageway). IF a nozzle is capable of reaching 30 feet from the end of 100' of hose from an interior stairway. There are a couple of exceptions in 905.4 including 905.4(2) and (3) that have this same distance. It is also mentioned in 905.5 for Class II standpipes

IBC is the code but the egress is for exit distances 200 ft or greater. The code is for 2.5 inch valves, and think of it as a horizontal standpipe. ( class 1 or 3 ) The required spray would have to include the tenant spaces and that could mean the travvel distance into each space would addbup to greater than 200 ft
The AHJ could of customized their requirememtd by adding amendmemts to it. The 100 ft plus 30 ft of throw usually applies to class 2 standpipes. ( 1.5 inch valves) but also applies to 1/ 2 the egress distance which is 200 ft as mentiomed by Dan above.
Class 2 standpipe is for occupant use . dont see an AHJ requiring that size.

The AHJ will frequently consider the logistics from a firefighters point of view. Most fire pumping apparatus have a 150 or 200 foot preconnected hose line. If the truck is parked at the curb, how far can that hose stretch without adding line. If it will not reach all points, I require a standpipe.

This reference is based on the IBC-2021 905.5 requirement of a 30-FT Class II standpipe (CIIS) hose connection + 100-FT of hose :

IBC-2021
Chapter 9 Fire Protection and Life Safety Systems
Section 905 Standpipe Systems
905.5 Location of Class II Standpipe Hose Connections
Class II standpipe hose connections located so that all portions of the building are within 30 feet (9144 mm) of a nozzle attached to 100 feet (30 480 mm) of hose. Class II standpipe hose connections shall be located where they will have ready access.

For Group B Business occupancy classification, a CIIS is not required by the scoping Code (IBC-2021) :

IBC-2021
Chapter 9 Fire Protection and Life Safety Systems
Section 905 Standpipe Systems
905.5.1 Groups A-1 and A-2
In Group A-1 and A-2 occupancies having occupant loads exceeding 1,000 persons, hose connections shall be located on each side of any stage, on each side of the rear of the auditorium, on each side of the balcony and on each tier of dressing rooms.

While a Class I Standpipe (CIS) may be required for this Project, CIS does not have this 130-FT (30+100) requirement in the scoping Code.

Yeah 've had to do that before, but typically not in Group B occupancy. It was for one specific AHJ that had amended the code to require it. Served as a good reminder to always check theier local amendments.
