Standpipes in Open Exterior Stairs
An existing high-rise hotel project in central Florida has open exterior exit stairs. By code and local ordinances, standpipe hose connections are required to be in the stair (hose connections on the corridor next to the stair are not allowed).
Since the project is located in central Florida (with lowest one-day mean temperatures between 25-30 degrees F, according to Figure A.10.4.2(b) of NFPA 13-2016), is there any way to still use wet standpipes and route them in the stair? Doing so could involve enclosing the standpipe perhaps in a small shaft and keeping the hoses in insulated cabinets. Or in this case is the best option just to have the standpipe be dry to completely avoid any freeze potential?

This is just based off of personal experience with a volunteer fire department. I'm not citing any guidelines or codes. Assuming the standpipe stands alone and does not service the sprinkler system, the simplest solution is likely to leave it uncharged and uninsulated. The fire dept. is going to charge it with their engines anyway, so the presence of water already in the system is going to make minimal difference. Constructing an enclosed pipe chase is costly to the customer, cuts down on stairwell space, and would need regulated airflow throughout its run. In other words, it's unnecessary.

Sounds like there currently is no standpipe in the stair.
