I was hoping the Vista20P/6160RF was a superset of the Lynx. On paper, it more or less is. In practice, not so much. Since I have both, perhaps I'll use both. Set them to unique house codes and use the Lynx/5828V for voice chimes, and the Vista20P for output triggers. A bit of a kludge, but it's the best option I know at the moment.
Best, Christopher
