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?

Hi there.
In the DM02 Manual http://www.cytech.biz/dm02_manual.html  page 4,
Some third party intercoms will not turn on their audio path until their in-house handset is off hook. If DM02 is used with this type of intercom, a means to simulate the handset going off hook and on hook is needed so as to allow the mic and speaker on the intercom to be activated. This is done via the DS Voice On and DS Voice Off Responsein Events > Misc Events in Comfigurator 3.1.3 and above. See the screenshot below. The DS Voice On Response is activated when the door station is turned on by pressing 0 for Door station. The DS Voice Off Response is activated when the door station is terminated by exiting from the menu or by hanging up the local phone after talking tthe Door station. These responses can be used to turn on and off a relay to simulate the intercom handset off hook or on hook.
To control the relays page 5 says

A door strike or automatic gate can be opened from the Door Station menu. The two menu commands “4 to Open Gate, 7 to Open Door” can be programmed to open a gate or a door using a relay connected to any Comfort output or the relays K1 (Gate) and K2 (Door) on the DM02. Go to Comfigurator > Events > Miscellaneous Events and look for the events Open Door Response and Open Gate Response in the list. Select or create a Response to be assigned to Open Door Response and Open Gate Response as required. If no Response is selected, the corresponding menu to Open Gate and/or Open Door will not be announced. Once a nonzero Response is selected, the corresponding menu item will be announced. To control the relays K1 and K2 on a DM02, use Action 200 (Open Door). In Response Wizard select Output > Open Door, then select the Door Station ID, the Door number 1 for K1 (Gate) and 2 for K2 (Door), and the duration in 100 ms units.  If there is more than 1 Door Station, use the IF Door Station ID action to program the outputs according to the ID of the door station eg If DoorStationId = 49 Then Pulse Output01 For 20. Endif
If  DoorStationId = 50 Then
        Pulse Output02 For 20
Endif
If  DoorStationId = 51 Then
        Pulse Output03 For 20
End If
The above Response for Open Gate or Open Door Response will pulse
Output 1 for DP ID 1, output 2 for DP ID2 and Output 3 for DP ID 3.


This should work for you

I apologize for posing questions for which there are direct and clear answers in the manuals. I was looking for them in the wrong manual. :)
I have some more questions, thank you for your patience. :)

1. The keypad (system has one and only one keypad, KP06, and no local telephones) doesn't seem to behave as described in Comfort User Reference Manual (the description is not very detailed, though). When call button is pressed outside at the building entrance, the bell chimes.

Now, this is what the manual says (Comfort II Reference Manual, page 16, i.e. 22nd page of the PDF file, downloaded from your web today):

When you hear the Door chime, press any key on the Keypad.

Any key means 0, as well, right? Pressing any key lights up the keypad. The text on the LCD doesn't relate to the incoming call (it says something generic, Security off, or something like that).

You will be asked to press 0 for Door Station just like on the phone.

How will we be asked? By text on the LCD? Or by voice message from keypad? There was no specific text. Voice message - maybe the volume was turned down or something, but I didn't hear it.

I press 0 anyway and there is some text on LCD, something like "Mic Enabled" (it was very brief, I didn't quite catch it).

You can talk to the Door Station in two way mode.

We have still some problems with audio. I can't find an up-to-date wiring diagram. How exactly do we wire mic and voice lines between DSI01 and DM02, and between the CM9001 and the KP06 keypad?

In the text quoted above, it says

If no Response is selected, the corresponding menu to Open Gate and/or Open Door will not be announced. Once a nonzero Response is selected, the corresponding menu item will be announced.

We have a response assigned to Open Gate event, but nothing is announced (again - how? by text on keypad or by voice message?). However, (blindly) pressing 4 actually opens the building entrance. So, the wiring and the programming works, only the keypad doesn't behave as we expect.

2. About the jumpers on the DM02 module...

2.1
The DM02 manual says that J1 should be set between pins 2 and 3 (away from terminal block) if the doorbell input is a voltage free contact (it is in our case). We inadvertently left it on pins 1 and 2, but it still works fine. Is the manual text wrong or...?

2.2
Does jumper J2 serve any purpose in our case? If so, how should we set it?

2.3
What about J6? We don't have either DS01/02, nor DP03x.

2.4
Same question about J5?

3.
If we wish to propagate a call from the building entrance doorphone to an external bell (we don't have any local phones connected and the users may not hear a chime from the keypad) which is connected to OP7, we need to pulse the OP7 output, as a response to the Doorbell event (in Miscellaneous Events), right?

Thanks!

Then the doorbell ringsd, press any key on the keypad. The keypad will announce "Press 0 for door station" (not on the LCD). pressing 0 on the keypad opens the intercombetween the keypad and door station. If you cannot hear the announcement then the volume may be too low. If you cannot hear the door station then there may be problems with the wiring. 
We have still some problems with audio. I can't find an up-to-date wiring diagram. How exactly do we wire mic and voice lines between DSI01 and DM02, and between the CM9001 and the KP06 keypad? 
For mic and voice connections, please follow this;
JP7 – MIC/SPK: Connection to Intercom Outdoor Station. Outdoor sttaion means your BPT
JP6 – MIC/VOICE: Connection to Comfort MIC/VOICE.



We have a response assigned to Open Gate event, but nothing is announced (again - how? by text on keypad or by voice message?). However, (blindly) pressing 4 actually opens the building entrance. So, the wiring and the programming works, only the keypad doesn't behave as we expect.
If you cannot hear the keypad voice announcing door or gate open then your keypad or voice may have a problem. Do you hear the keypad menu when you enter your user code and # key? when you arm and disarm  the system does the keypad announce away mode or security off?

The DM02 manual says that J1 should be set between pins 2 and 3 (away from terminal block) if the doorbell input is a voltage free contact (it is in our case).

You should set J1 according 5to the voltage free contact, This ensures that it works in all conditionsJ2 is for the volume of the doorbell tone on the external door station. There should be some difference in the tone volume

J6 should be shunted


Same question about J5? If we wish to propagate a call from the building entrance doorphone to an external bell (we don't have any local phones connected and the users may not hear a chime from the keypad) which is connected to OP7, we need to pulse the OP7 output, as a response to the Doorbell event (in Miscellaneous Events), right?
J5 shunt should be  removed. yes the doorbell event can be used to pulse the output
