Hi
I'm hoping someone may be able to help me with a faulty telephone door intercom.
I live in a house that was converted into four flats over twenty years ago. The flats use a Urmet intercom system for the door that allow people to buzz the intercom phones in each flat. You can then use the button under the receiver to unlock the main front door.
Recently I've found that the ringer in my intercom phone does not work when the outside button is pressed. However, if I pick up the receiver and then someone tries the outside button the speaker in the handset will make a buzzing noise. The same buzzing noise can be heard from the speaker outside. So I know there is some sort of connection. We can both hear each other talk but it is quite faint. Also, when the button on the telephone is pressed it does not activate the door to unlock.
I have no idea where the cables for this system run. We recently had to deal with a dry rot problem that required the ceiling to be removed and replastered in the outside porch area above the external intercom box. So I can't be sure if the cable to my downstairs flat was disturbed during the work. The other three flats all still work as far as I know.
I'm really not sure what to do. I thought I'd ask on the forum first before I go to the expense of getting an engineer to look at it. I'm not even sure if it's possible to get replacement handsets for systems this old.
If it helps here is a photo of the inside of the telephone intercom. The green wire is not attached. However, the only diagram I could find of a similar system on the web showed all the same connections. So I assume that the green wire was never attached.
Any help would be greatly appreciated.
Thank you.
