Uniphone TK6 Intercom Connection Issues with a 6-Wire Cable: Functionality Concerns

I have a problem with connecting the TK6 Uniphone.
My problem is that I have a 6-wire cable. After a dozen or so attempts, I was able to connect the handset, but not 100% efficiently:
Problem with connecting the intercom Uniphone TK6 -> 6-wire cable.

On the left, my connection (graphically) and on the right (photo) how it looks.
I have the following problem:

MINUSES
1) after picking up the handset from the cradle, when someone rings again, the handset rings terribly;
2) after removing the handset from the cradle, you cannot hear me downstairs;

PROS
1) hear what is going on downstairs;
2) I can open the door with a button;
3) when the handset is on the cradle, the intercom rings normally.

I am asking for your help.

My friend. Since, as you write, after a dozen or so attempts, you managed to connect it tightly, there is a high probability that you damaged the microphone amplifier in the uniphone. This can be done, for example, by connecting the opening cable to the microphone terminal (4). This can be done in 2 ways. 1- is a meter in hand and measure everything, or determine everything according to the wires, starting with the power supply. If it is a multi-apartment system, you can still visit your neighbor. Installers usually keep the colors of the wires, but first I advise you to check the uniphone. In TK6 you can burn transistors very quickly.

When connecting https://obrazki.elektroda.pl/8218408800_1355931298.jpg, it is finally like this:
(+)
+ I can hear what is going on downstairs;
+ I can open the door;
(-)
- you can't hear me downstairs;
- the intercom does not ring when the receiver is hung up.

Is this the amplifier?


Can you buy the above part?

What you show is not an amplifier but an electrolytic capacitor.
You can buy everything that is present in such a uniphone.
You probably mean the transistor. You cannot see it from this side of the plate, because it is clearly on the other side. However, before you start rummaging around in electronics, check carefully if you have exhausted all possible connection combinations.

and where is the amplifier ...?

Sometimes the amplifier is on the PCB and sometimes at the microphone in the handset.
I have never looked at it from this angle. Getting connected is easy. You probably have a badly connected ground.

what about

is it possible?
Because there is an analog network in the cage, so the uniphone should work.
Most of the people on the forum say that they have voice problems (can't hear the person in the apartment downstairs).
Is it the fate of these uniphones ...?
If I change it, no matter what cable, it goes to hell (everything is shimmering then).

I have a question - Where is the microphone amplifier located?

I have already written about it above. The amplifier (usually one transistor) is located on the uniphone board or next to the microphone in the handset.

Hello,
I also have a problem with the correct connection of the TK6. everything works except for opening the lock,
I attach photos of the old connection (soldered wires), diagram, my TK6 connection.

In the original (soldered) connection the white wire was not connected (not even isolated)
please help

Put the right jumper on or make a connection (with a cable) to connectors 2-6.

Thank you Ircys, I connected 2-6 I smiga

Gentlemen, Lord, I have a question.
I have a 5-wire installation, I bought a uniphone (because it only needs to change the handset in the apartment) with 2-wire connection, can I connect a 2-wire uniphone to a 5-wire installation?
Thanks in advance for your answer

There is no such possibility if the previous uniphone was in the 4 + 1 system, you probably bought a digital or analog digital uniphone from Cyfral, two-wire.

Gentlemen, how can I prevent the other resident from hearing what I am talking about in a two-family uniphone (this is how it is now ) and two, if I pick up the phone without the bell, I can hear everything from the court

The second thing you write about is a kind of "advantage", because you can overhear what some strangers are talking about at your gate.
The first one results from the simple structure of the intercom set. After all, you don't have to talk to someone under the gate. The intercom serves only to identify the interlocutor and to let him in or not. Telephones are used to make calls.

e.g. install a digital intercom

Hello, I have a problem with the rwk intercom

I am sending two photos of the new and the old intercom. I connected the new intercom as follows:
1, blue
2, white
3, brown
4, green
5. gray
6, brown
The problem is that with such a connection, the opening of the lock works, with the handset removed, you can hear the conversation with the person below. you can not hear only when someone is calling at the bottom with the intercom, I tried to change the cables of numbers 1,2,3, which resulted in the fact that when calling from the bottom, the sound was heard only at the bottom and with the handset removed. Before me, it was assembled by some bricklayer who was renovating the flat, the cables were connected blindly when it happened, nothing worked, is it possible that he damaged something?

Here you have exactly the same uniphones and their exchange. Link .

I was guided by that topic when connecting. but it doesn't work as it should, the bottom call doesn't work what could be the reason?

1. worked before? maybe a broken button or an open circuit
2.Conversation heard both ways clearly, loud?

everything works on the old one, but it doesn't want the new one. conversation can be heard normally without any disturbance. Only someone in front of me at random plugged in this intercom and when I took off the handset I could hear such a hum. Is there a chance that something has broken on this new intercom?

I do not think so. I have not encountered any damage to the uniphone due to bad connection, unless mechanically. Do you check it when the forks are pressed?

yes and it doesn't work. When I replace the 1,2,3 cables, I do not remember exactly which, probably 1 of 2, then the call can be heard only with the handset removed and as if at the bottom in the loudspeaker and in the handset. Can you check if the connection from the above entries and photos as described is correct?

Try to swap the ground and loudspeaker wires with each other.

greetings

Hello . Today I tried to replace the ground and loudspeaker wires, it did not work. I connected all the cables peer-to-peer except those responsible for unlocking the lock with the earpiece on and nothing. On the other hand, when the handset is removed, when connecting the wires: call and ground, the loudspeaker will hear the call to pins 2 and 3, i.e. ground. I suspect something may be wrong with the handset. on Saturday I will try 2 more new handset.

that is, the call comes ..... A colleague from another thread had a similar problem and it turned out that he was checking the call with the receiver picked up ...
greetings

But I checked with the earpiece on and nothing worked until it was removed, it started to work with the earpiece removed and connected, as I wrote above. Tomorrow I will see with the second new intercom, maybe something is damaged

Hello, the intercom was broken on the second, everything works Thanks for your help
