Interfacing with Fermax Intercoms

[ident]

Many Fermax Intercom models can be interfaced to Comfort by DM02 and RGR05 so that the doorbell will ring the local phones in night and security off modes and call to mobile phones when armed to away or vacation. You cabn also open the door or gate from the telephone.

See the fermax website http://www.fermaxuk.com/10/384/pagina.aspx
 
The \"4+N\" types can be used.  This means 4 wires + the number of houses or apartments. For example for a single house, 5 wires are used to connect the outdoor visitor call station to the house and for a block of 6 apartments, 10 wires are needed.

Other types like VDS or digital or Bus types cannot be used

The Cityline, Skyline, Marine series have 4+ N versions that are suitable

Please consult with the Fermax technical sales for more details of available models

I followed the advice to ask Fermax technical sales, did not get anywhere.
When a technical sales person tells you how much they hate automation and integration, you have to take any advice with a pinch of salt. 

Does anyone know if kit 9411  or kit 1421 will interface with Comfort?

The first one listed seems to have the correct connections but the 2nd 1421 has no information about the connectionsIf they are expensive I would be hesitant to try unless someone has tested
We have not interfaced with fermax intercoms for some time
