Taurus is just the style of cover in case you didn't know.
I'm assuming you have linked out OV-TR at the 9448 to test and use without SAB connected?,
Anyway great choice of panel and sounder,it would be nice for us to use the multibox again but that's a long story so :
cqr ......scanny 9448+
STB to STR
TRIG to Bell
HOLD - to 0V
HOLD + to 12v+
RTN to TR
Wire the sounder first then make the connections at the panel.
Be safe and don't forget to remove that OV/TR link :)
