Todd, As a retired AHJ, my opinion would be that you do not need the hose valves on the first-floor standpipe risers for fighting a fire on the first floor, since access to the first floor is not gained through the stairwells. However, you'd need to pass that by the fire chief of the department responsible for providing that service, and the permitting authority for the installation for approval. One of the last things that you want to do is create a condition that is not expected by the fire department, so such an arrangement needs to be incorporated into the building preplan. As a firefighter, I would expect that hose outlet to be there (on the first floor in the stairwell). We use it for fighting fires on the second floor, and as an alternate method of supplying the standpipes if for some reason the fire department connection is dysfunctional.
I am working on a small 4 story building where we are required to install a standpipe (as well as a full 13 sprinkler system). The first floor consists of a conference area, office space and various mechanical and storage rooms. The conference space and office area have direct access to the outside, but there is no communicating space between them. The 2 stairways lead to an outside access only. The elevator lobby has an outside door but does not connect to the stairways or conference and office spaces. The total footprint of the building is less than 3000 sqft. Where do you put the hose valve on the 1st floor?
