Aiphone system communication gets cut

[ricardot1q]

Hi there guys, I have this issue.

At the moment I have an aiphone gt-mkb-n central alongside a gt-1d.

When I do a call from the guard station, up to the resident there is no issues, but when I do the opposite (from the resident to the guard station) the communication gets cut.

Did you try swapping out the residents unit? probably a bad microphone.

It's where the earth work was last done, can you revere the wires and see if it's only nicked on a few wires?

This is the most God awful intercom system I have ever seen. There is no telling from the little information you give what the problem might be. Beyond swapping the resident unit with a known good one, unless you have experience with this system and how it was installed you need to contact the Aiphone dealer who installed it.

Here is the installation manual:

Where did this information come from??

It was a guess, if they have an intercom they usually have other help around the house...
