Wiring Question

So, the smoke/fire detectors that were wired into the previous alarm system were wired to:  (w) to Z6, (g) to Common Ground, (r) to Aux +, and (black) to PGM1.  

Additionally, the Siren was wired to Bell + for Red, and Bell - for Black.  

The Konnected that I have has an Alarm +, Alarm -, and Aux -.
How should I wire this successfully?

And with the Piezo Buzzer, there is no OUT option on the board.  The Instructions on the Konnected site seem to be incorrect/misleading.  How should this be wired into the system?
