Controlling an 801 bell intercom system with a Fibaro 213 switch? Help needed

Hi,

I have an 801 bell intercom system in my apartment which allows me to unlock the front door to my apartment block. I would like to control the door unlock mechanism using a Fibaro 213 single switch and SmartThings.

I am not sure where to start with wiring both devices together and I was wondering if someone could give me a hand in setting this up.

Below is a link to the diagram of the intercom system:

Here is a link to fibaro manual, page 7 has the wiring diagram.

Cheers,
Dan
