At home I used the Digi outputs as inputs into loxone through 12v relays and then used the -ve bell hold off through a loxone relay to control the sounder.
This enabled me to use loxone to control the alarm using the existing texecom panel as an interface between loxone and the sensors and sounder. I gives me access to the 4 texecom wireless pirs for lighting and heating control too
