I added the Mercury Panel manually, but cannot connect to it.
The station must have the correct credentials (username and password) to connect to the panel. In the Database pane of the Device Manager, double-click the device and define the expected credentials.
An acknowledgement does not propagate.
There is no acknowledgment link. See Set up alarm and acknowledgment points
