Elvox 801 Intercom System

[npm93]

Hi,

I have recently purchased a flat with an old Elvox 801 system & I tried to install one of those new Ring Intercom systems. I messed it up, and put the Ring Intercom back in the box until I have time to call them. Problem that I have now is that, my Elvox system won’t work (it has a low volume buzz it never had before when someone calls & then I cannot release the door using the button on the phone).

I am not sure if I’ve messed up the wiring. Here is a photo as it is at the moment. Any help would be appreciated. My neighbour who I am friends with unfortunately had his handset replaced by the previous owner so cannot even reference his intercom system.

Thanks.

The wire colours mean nothing really as was likely decided by the installer rather than any standard.
Terminals are usually labelled , so if you note connections on your neighbours unit with the model number of the handset, you could likely work out your own handset
There's a website called INTERCOMS R US and they show the relevant terminals and functions.
Handsets are not as complicated as they appear.

You may have blown the fuse in the power supply for the AC side , some systems use a multi power supply 12ac / 8v dc

So one of the neighbours is a good friend, but he has a different phone. So if I take the cover off his, I will likely be able to see the wiring?

His phone is the attached image. The site maintenance manager has given me a number for an electrician that has knowledge of the system so fingers crossed.

You would have to cross reference between the Videx terminals and the Elvox handset

Lesson learned: take a picture of how it's connected before you make any changes.
