Recently got my Konnected PRO with the Interface option. Mostly have everything working, but wanted to add a Piezo for Chime in area of house where Panel is.
I have Vista20P with 8 zones. Konnected PRO supports 12. This leaves 4 zones on Konnected board unused. I have already used both of my OUTPUTs on Pro Board with my relays to ARM STAY/AWAY modes.
I would like to use one of my unused PRO Zones as Output 3.3V to wire a Piezo Buzzer. I may also like to add a new contact switch and maybe a motion detect at some point in the future. Yes, I understand these new switches/motion detectors wouldn't be available to my Vista20P, but is there any reason I couldn't wire them for use with the Konnected PRO empty unused zones?
My immediate task is the Piezo buzzer. I have the positive side connected to an unused Konnected Pro zone, and negative to common ground. Is this valid? I cannot seem to get Piezo to fire, and wondering if I'm expecting the product to do something it wasn't designed for.
In general, are those 4 unused zones useable in the PRO when using the Interface integration? Do all zones have to be in Traditional system to be used with Connected?
If so, any ideas what I might be doing wrong? Has anyone done something similar successfully?
