intercom problems

Second fixing a house today for a customer , which had been wired for a intercom , call point at front door and side door , and hand set in kitchen , customer went and bought a COMELIT STYLE 5 KIT today with a second call point which the wholesaler took out of another kit , when we went to connect it there was no drawing to show the way we wanted to do it , so i just looped the call points , when we went to test it there was very bad interference when in operation , so we disconnected each call point separately and tryed it , it worked fine , so my question is , have i it wired wrong or is the kit missing some thing ,
Thanks all

Comelit is a good system but sometimes very hard to follow connection diagrams, but they do have a very helpful helpline. The phone no. should be on the box.

Are you running the power on the same cable as the audio.?

ya runing power on the same cable , but with one call point disconnected it works perfect

It's very difficult to diagnose your problem without studying how it's wired and with the diagram at hand.

But if I had to guess, I'd say you'd need a switcher which switches off the call point you're not using.

Some systems will give a hum if the power in is on the same cable as the audio.But as fred said I would need to see how its wired.
