Connecting and Replacing Old Intercom with New Urmet 1131: Wire Colour Guide

Hello I'm desperate and I don't know much about electronics!
I have an intercom that is in agony, more tape and glue on it than possible the decision was made to replace this device (wife It wouldn't be a problem if I knew how to do it !!

In the old intercom, the wires are soldered to the board, there are 6 of them, the new (almost) Urmet 1131 intercom, as far as I remember, has 5 places to connect the wires. Can you tell me what color of the cable I should connect to which contact of the new intercom to make everything work
photo 1 shows my old intercom
photo 2 new but this is a photo from the forum from you and there I see 6 places to connect I think there are 5 :)

1


2

in total, in photo No. 2 you can see the colors of the cables, but you can see two red ones there and I don't have two, maybe it's a bridge? , secondly, it seems to me that there are 5 places for screwing the cables and in photo 6 I do not know if there are different types of intercoms with 6 and five connection points!!??

Please help, my wife has premenstrual syndrome, you know what that means

Hello !
There may also be 6 wires in the Urmet uniphone, but you can't see much in the picture of the old uniphone, take a picture of the whole thing so that you can see where these wires go, you can suggest something!
Regards !
Robert

I've never installed these, though
CA - is a call
1 - handset (SU)
2 - microphone (MU)
6 - mass (0)
9 and 10 opening button

The picture shows a broken bridge. This must be the case with a six-wire system.
For starters, set these two to the open button. Save these colors. Then (if you have a meter) you'll be fine.

well thanks for showing interest The day is coming to an end, I'm burnt out
I'm attaching a photo of the model I'm about to wear:



, as I said, I have five places to which the wires can be connected, not 6 as in the previous photo (moreover from the forum) and now the second one that is to be replaced : ( Someone asked for more :)

]

someone wrote to me:

2 - mass 9-something else etc ..... can you, if it is predetermined, speak in colors ?? because I don't really know how to determine which mass has which functions

Hello !
You have 5 because you don't have a screw from 1, you either fell out or it wasn't there and it should have been!
Your photos still don't show the microphone or the speaker, so you don't know where these wires go!
Regards !
Robert

should I take a picture of an unfolded handset, an old intercom????

If you don't have a meter, disassemble the handset and see which wires from the twisted cable are connected where. There will most likely be 3 wires coming out of the handset, where the one that connects one contact of the microphone and the loudspeaker in the handset is the ground that should be connected to terminal 6 from the new uniphone. The wire that is connected to the second contact from the speaker of the handset should be connected to terminal 1 (where you do not have a screw) and the wire from the microphone to terminal 2. To determine which wires are responsible for opening the electric strike, unscrew this plate in the old uniphone and see which wires this opening "plate" shorts and connect them to terminals 10 and 9 and you will have the last "call" wire that needs to be connected to the CA terminal

welcome back ! So I did as you advised me the intercom works almost flawlessly but it almost makes a big difference ........ you can't hear me downstairs, the silence is like sowing poppy seeds, the rest of the functions are ok
please advice

The second clamp is the microphone. You must have a DC voltage (plus) in the range of 8-15V (relative to the ground cable) on the cable you connect here.

And I have a question.. I would like to add the ability to turn off the ringing signal, so I thought I would add some ordinary switch (because probably such a solution is correct), and now should I connect this switch to 1, i.e. the loudspeaker lines or to the CA-call? Yes, I have it all connected:

The easiest way is to put a regular switch under the call line, i.e. CA. I wonder what the potentiometer on the handset is for, but that's another story.
Regards

Thanks for the answer. And the potentiometer is probably a remnant of an earlier intercom

In series from the circuit breaker (or potentiometer) call line to the CA. The second potentiometer is probably the volume. Maybe with the new one it will be redundant.

I don't know what power supply you have, if it is 18N or 19 ... then the volume and call volume control is in the power supply. You definitely need to disconnect the perk from 1.

I am also for the elimination of this potentiometer. Sometimes I put a resistor (470-1500Ω into the line of microphones, but only if there is feedback when picking up the handset.

Hello, I won't create a new topic, so I'll ask here.

I have an F&M WRD 6i intercom power supply, I can't find a diagram for this, can anyone decipher this power supply?
The installation is with an electric lock,
And there is one more question, is it possible to connect a total of 3 uniphones to this power supply, to a 3-button intercom, everything is URMET, uniphones as in the subject.
I will add that here, where there are the most wires, there is '' - ''

The number of uniphones is arbitrary. It depends only on the cassettes, i.e. how many buttons it has, so many independent uniphones can be connected.
Download the manual from the WRD-45i, for example, because the markings are the same.

I support the previous speaker because if the number of call buttons is equal to the number of uniphones, then it is ok. In the case of 1 call button, I would not exceed the number of 3 pieces due to the load on the generator line.

in the cassette of the intercom I have a diagram, and zaicski 12v, 0v|, |GL, GL|, |MK, 441|, G1,2,3, G, to which one should the generator signal be connected?

Logically, the generator input will be G and the generator outputs to the subscribers will be G1, G2, G3.

Anyway, here's a piece of the installation diagram.

It helped me a lot, thanks for your help!

Hello, I'm just replacing the intercom with 1131, I connected everything and it seems to be fine, but the problem is that I can't connect the microphone because then the speaker at the bottom goes crazy and you can hear a squeak, I mean I think so because I only heard it through the loudspeaker in the intercom handset, and when I call it is almost inaudible, what to do then?? I should add that I live in an apartment.

Hello
Buddy, try to load the microphone lines (MU) in the camera with some resistor, e.g. 11k, because you have a new camera and you may have feedback.

Hello,

I have the same intercom. Unfortunately, this is a truncated version and there is no volume down. Please advise where to insert and what potentiometer to enrich it with this option?

Regards,

Put the resistor on the microphone terminal. If we don't know what the value should be, we try different ones. Most often it is supposed to be a resistor in the range of 1 kΩ. Of course, you can give a small potentiometer as a resistor (if you want).

But you probably described the method of how to turn down the microphone to hear it less at the gate and I had to do it, because if it wasn't for the potentiometer, I would only have a squeak at the gate. But if a colleague meant, for example, to lower the voice in the handset speaker, then the potentiometer should probably be on the speaker terminal, while when it comes to lowering the call, it should be on the call terminal. At least I think so.

Hello
I have an intercom urmet 1131 connection as in the attached photos
handset green red cable
blue and white microphone
while camera 1-dark brown, CA-light brown, 2-green, 6-blue, 10-empty, 9-red
The problem is that no one can hear us downstairs. We hear them and can open the door. Is there an error in the installation in the building or is the connection wrong

I replaced the old GM-WO handset with the Urmet 1311. Everything works except the microphone in the handset (you can't hear "Who's there?" with the cassette). In GM-WO it has only a diode on the board, and in Urmet there are already several capacitors and resistors. Can you tell me what is the cause of this and how to solve this problem

The new one has some elements that the old one didn't have, but don't worry about that. In the old one, these elements were probably in the microphone itself (microphone amplifier), because it used to be done anyway. Regarding the connection itself, you did not provide a list of the old uniphone, so how can I help you?
