What is your section reference out of NFPA 14?
RE: COMBINED STANDPIPE SYSTEM
cdafd, the picture you provided is not a floor control valve but a floor manifold. It provides a package drain and flow switch.
Floor control valves on combination systems are normally butterfly valves with internal tamper switches. Sometimes, you will see an OS&Y valve with a tamper switch.

The test connection could be for a Fire Pump. Two very separate animals..

Combination standpipe just means that the vertical pipe serves sprinklers and hose valves. Matt's diagram is perfect for the description. If you have pressure >175 psi, then you need pressure reducing valves. These are often a listed control valve/check valve.
