PTP850S and Data Port Wireless Down Alert

We recently transitioned a number of our links from PTP800 to PTP850S. We have ring protocols running (not STP) to manage failovers. On the PTP800 we used the “Data Port Wireless Down Alert” setting to ensure that failovers happened quickly if the wireless goes down. How can I do the same thing on the 850S? I don’t see any settings that seem to correlate, and I don’t see any way to configure similar behavior through the Alarm Configuration.
