Doorbell wiring question (DSC Communique intercom)

*Warning, newbie*

 

I'm trying to figure out how to attach a door sensor to my unique DSC intercom.  I've got a Fibaro door/window sensor that has a spot to connect a doorbell (according to the instructions inside).

 

The DSC intercom has a wiring diagram I have attached.  Can I just wire the Fibaro sensor right to the intercom on the OR/BR listed in the diagram?  This isn't a normal doorbell.  It is an intercom on a DSC Communique phone system.  I would like to trigger the Fibaro sensor from the doorbell so that I can queue a ring/sound on my Sonos system.

 

I'm attaching a picture of the pcboard -- you can see the red/grn/yel/blk wires that are mentioned on the diagram.  I assume the OR/BR are the GRY and BLU.

 

All of the typical doorbell/zwave approaches I see online are more oriented to the existing siren/chime and/or the transformer.  In my case, I don't have any of these as the intercom/doorbell rings via the DSC phone system.

It appears that there are two models, one with the optional door button connections and one without.

 

My doorbell looks like the one in Figure 3 that mentions the extra wires.  (The outside looks like Figure 3.  It doesn't have the extra buttons that the figure above it has.)
