Assistance needed connecting external sounder

Last weekend I connected the wires of my previous alarm system (Menvier TS400) to my Konnected board. Sensors went flawlessly! So cool to see the sensors changing when there is motion in the house :-)

The only difficulty I have is connecting the external sounder to my Konnected board. How is able to help me which wires need to be connected to the Alarm and Ground on the Konnected board.
Below are picture of the previous system, and specifically the part of the external sounder. Also included two sections of the Menvier manual which describes the External Sounder connections.

Would be very grateful if someone can guide me in the right direction!


Have been struggling to find any info on hooking up external sounders too.
