wire to your bell trigger is the standard way not the strobe, unless you have separate outputs, for Fire PA and alarm.

you would wire the bell trigger to C based on C being already programmed for alarm, but if you took it to any of the others you would need to setup a new message for alarm.

as for polarity, if when the dialler is connected it tries to make a call and the bell isn't active, reverse the polarity on the dialer input and fire the bell trigger.
