Join Flood and Freeze Sensor to existing zwave network

I'm interested in getting the Ring Flood and Freeze sensor but I already have a zwave network and don't need the Ring Alarm Base Station. The documentation is a little light on joining to something other than the Ring Base Station. If this indeeds uses the zwave standards, could documentation for a standard inclusion be included as well. In addition to asking about the Ring Flood and Freeze sensor, do the other Ring Alarm z wave products work without requiring the Ring base station?
