Alarm output

I’m setting up my new V2 12 zone systems.  I am using SmartThings on my IPhone.   All the zones are working.  When I trigger the alarm, it shows on my IPhone and I get a text message.   But, there is no voltage output on the board to the bell.   Any ideas?

I am having the same issue. Looking for suggestions.

Leonard, are you able to activate your siren/bell manually from the SmartThings Home Monitor app on your mobile device?
