Mall Hose Connections Considered a Standpipe?

7/9/2020

I have a covered mall under 30' tall that requires hose valve connections in accordance with the International Building Code, Section 905.3.3.

Do these hose valve connections count as a standpipe that requires a monitored isolation valve as per NFPA 14 6.3.2?

Is they are supplied by the sprinkler system they require isolation valves.

This is a great question. I think when IBC 905.3.3 says "Class I hose connections connected to the automatic sprinkler system," it means that the sprinkler system does not have to be isolated from the standpipe system, but it doesn't necessarily imply that hose valves do not need to be isolated from one another.

Without language in the code addressing this more directly, I would probably want to clear the interpretation with the AHJ before omitting isolation valves.
