Hello!We have a penthouse apartment in a multi-apartment building. The building has an analogue multiwire doorphone entry system manufactured by BPT (an italian manufacturer). The client wants to use Comfort system to answer the doorphone calls and open the building entry door.
In the attachment, I'm sending our wiring diagram. K1 relay is activated by BPT system bell signal and this part works fine (call from the outside comes through on the Comfort system (keypad etc.).K2 relay needs to be activated by a Comfort output once the user answers the call, and deactivated once they open the door. This way, the MIC and SPK lines get active. We're using (per example) output 8.
Our idea was to program PhoneOffHook misc event to activate output 8 and PhoneOnHook misc event to deactivate output 8.
However, we get no audio either way.

It is necessary to keep MIC and SPK lines disconnected prior to receiving a call because otherwise we receive calls to any of the tenants (whatever call button somebody outside presses, we get the ring, unless MIC and SPK lines are disconnected - the original in-apartment doorphone unit has a dual microswitch that mechanically disconnects both lines when you lay down the handset).
Also, door opening doesn't work by itself. Do we need to specifically program an action to activate relay 1 on the DM02 module or does it activate by default when user presses 4 on the keypad?
