How to add Fortrezz Strobe Siren to Smartthings V2 Hub

In the UK, the Fortrezz Strobe and Siren isn’t officially integrated into the SmartThings system however i wanted to see if anyone in the community has managed to get it working manually. Im thinking of adding it to the new devices section on the online web control system. Has anyone else been able to get it working and if so how?

Any help would be very much appreciated.

I have this strobe siren also.
I am using it with the SmartAlarm device type (internal)
But it sometimes gets unresponsive (although it works) on the GUI.

I suspect that this is not the correct device type that should be used with this siren.
Which device type should I use ?
