The trouble with the module is that it's very basic. With a professional panel, there are lots of features built in. Monitored power and backup is one important one for a start.
If you connect to the SAB based sounder without any form of backup, the sounder will activate when power fails. If you do have a ups, will the konnected module let you know you're on backup and the battery status?
There are options for Texecom and Honeywell Galaxy for MQTT. At least that way, you're getting a robust security solution with additional home automation capability.
You can bolt on the konnected module to some panels, but not with many of the professional panels using balanced input zone circuits that the konnected module interferes with.
