Guidance on Connecting a 6-Wire Handset to Intercom in Apartment Block

Hello!
I bought a flat in a block of flats and I don't have a handset there, only a 6x0.5 wire sticks out. You should probably buy a 6-wire handset, but how to find a microphone, loudspeaker, generator and electric lock? Are there any ways to do that? If you can help me, please. Thank you in advance for any hint

If only the wires stick out, you need the whole hearing aid, not just the handset. Each new hearing aid comes with a user manual that explains how to find the right cables. You can try the option with the neighbor but... not everyone is friendly. It would be a test. Good luck.
P.S. The device, of course, for a 6-wire installation.

Hello!
Well, friends, not always the number of wires protruding from the wall determines the type of intercom system.
I advise - as - someone to look at the neighbor beforehand and take a picture.
Ew. photos of the cassette at the entrance.
Hi!

Well, I know that I need a handset not only with a cable, but with a base, but there are only connections, opening and disconnecting the handset. I'm new in the cage I don't know anyone yet and you know how some people look at someone's handset from the intercom? Maybe someone will be kind enough to post a pic. As soon as I have I will post. Thank you for the replies. Regards

What about a block??
Surely there is an ADM or Administrator and maybe they have someone who deals with it.
When you buy a flat, you have to contact ADM anyway.
The end of the tongue for a guide...

That's how I found out, but it's a last resort because maybe I can connect myself, not everyone has enough money to hire professionals for everything. I will first look for an electric strike, then I will only have 4 wires to connect

Well, I contacted the previous owner about where the intercom handset was and it turned out that he had it. I didn't need this handset because I'm going to buy a new one anyway, but I managed to take a photo of it with the consent of the previous owner. I'm just wondering why pin 5 is empty and moved to pin 2?.

Counting from the bottom of the clamps
6 lock
5 bridge lock with 2 (ground)
4 microphone
3 handset
2 mass
1 call

there are four ways to connect
1. call a professional service ...
2. go to your neighbor, if he has the same camera, write down the colors and order of the terminals
3. having a loudspeaker (in the device) terminals 2 and 3, you are looking to listen to the microphone from the cassette,
having it, you are looking for opening the lock by touching one of the cables to the cable from terminals 2 and 3 once you hear the characteristic BZYT (growling) connect terminal 6 (you have 3 out of 5 cables, the other 3 are the microphone call and free wire) connect to 4 remaining cables need help person to check downlink communication, if no connection, switch terminals 2 and 3 cables and try again. You connect the remaining 2 wires to terminal 1 one by one, move the handset away from your ear and send an assistant to press the button in the cassette. If you encounter problems along the way, see point 1, call the service, this may indicate damaged cables...
4. Having a meter, you can measure the resistance of microphones, speakers, I can't tell, I don't remember, I'm counting on friends from the forum or ... (e.g. you need to check with your neighbor, but when you get in, you will see the colors of the cables, which will make your work easier, If you are unable to take any actions see point 1 Call service .....
If you are going to put on this camera, you already have a description of the terminals,
if you buy another one, take a photo of the new camera and the neighbor's camera, post it on the forum for him, we will do everything for you and you only need to tighten the screws under the clamps

PS JUMPER on pin 2 ground pin 5 the opening of the bolt is stopped by the ground fed to the relay, the relay gives 8-12 V variable to the bolt

This is called a comprehensive answer. I think that with these tips I can handle it, as soon as the handset comes to me, I will fight with the connection and of course I will write about the results. Thank you and best regards

If it will not be WEKTA TK-2 as in the photo, give a photo of the new camera, improve the description of the clamps.

It doesn't matter, because someone would have to bridge it anyway. Originally, there is a mass on terminal No. 5, and here it is moved to 5, i.e. if it was to 2, it would be necessary to make a bridge from a short wire between them.

Hello after a long break.
So I bought a regular WEKTA handset, I connected it identically to the one I had before (photo posts earlier) and there is a problem because everything works except that you can't hear me downstairs. I am attaching a photo of the headset, please help. Regards

On the uniphone plate you can see a small blue "podkóweczka" with a white circle. It's a mounting potentiometer. It is set to the left position. Turning it to the right increases the microphone gain.

Welcome back!
Unfortunately, turning the potentiometer on the board did nothing. My connection looks like this:
From the right, 1-orange, 2-bridge with 5, 3-green, 4-white, 5-blue, 6-two white. I have the same connection as the old intercom.
Maybe the handset is damaged? Regards

Hello!
There should be a voltage at terminal 4 - 8-16 V when the handset is hung up, 3-6 V when picked up - 3-6 V depends on the parameters of the power supply. This is the voltage supplying the uniphone electret microphone. It is best to measure the voltages on terminals 4 and 3 relative to 2 (ground). If the wires protruded from the wall for a long time and were short-circuited, the power supply may have been damaged.
Hi!
PS Does your colleague have a multimeter and know how to use it?

The cables from the beginning of the renovation to the end were separately insulated, so there was no chance of a short circuit. I replaced the handset and still the same, I don't have the strength anymore because replacing the wires does nothing because it either doesn't open or doesn't ring or can't be heard so the connection seems to be ok, I'm wondering about these jumpers in the picture are they supposed to be put on or removed?

The jumpers are used to open the lock, and more precisely to configure the uniphone. They are to be installed in a 4-wire system. Removed with 6 wire. You have it removed in the picture.

Today I decided to take a look at the cable that is in the meter box that I have next to the door. All cables are connected to some main thick black except for one white which is probably in terminal number 4, which is responsible for the microphone, but I have not yet found where it should be connected and should it be connected at all? Can you answer me? There are two more white ones but they are connected and plugged in so there are 5 wires connected? Is this correct? Regards and please reply.

Hello, I live in a block of flats (the intercoms are 10 years old - they keep replacing the switchboards)
Can anyone advise me on which handset should I choose?
Currently I have an old corpse - and this is what the cables look like at the back: WRONG PLACED PHOTO
Any info on what to buy and what not to buy - will be very valuable.
And of course, I would like to ask you to include the number of wires that are in the old handset (so that later there would be no connection circus).

You need a Radbit uniphone (3 wires) http://www.radbit.pl/index.php/unifony

Or maybe something from commax - because the company you provided is not very convincing to me as to the appearance and operation of these headphones. Anyway, I don't know if the old one wasn't from them as well.

It will not work.

Based on the photo, it is impossible to clearly determine whether the uniphone is analog or digital (both versions were mounted in such housings). You can verify from the photo of the inside of the handset.

None of the generally available uniphones will work in this system.

Hello! I don't quite understand. Do you have 5 wires connected on the cage? I would love to see a photo of the connection in the stairwell. Regards.

Here is a photo of the middle.

I'm not sure, but the intercom service technician said something that it's best to replace this handset because there are punctures (that when someone calls a neighbor) I can also hear beeping.
So I guess the digital switchboard has already been replaced (but I'm not sure) and I don't know how to check it.

Digital uniphone, coded with high probability to number 2 (from the description on the PCB, because the bridges are not visible from the print side).

The crosstalk effect appears in these uniphones as a result of incorrect placement of the handset (deformed handle, the one fixed to the wall)

No less I repeat the question - what handset to buy to serve for years?

Radbit digital uniphone, Ircys provided a link to the manufacturer.
Will it last for years? This question is for the fortune teller...

I have a problem with connecting the cables from the old handset to the Wekta.
In the old one, terminals 2 and 6 were bridged, and one ground cable was not used and therefore I do not know what mode it is in (3+1, 4+1, 5+1?).
How should it be properly connected in Wekta, because for now I managed to open the bolt and call, you can hear the guest, and the householder at all

I also measured the voltages
green - 7.63V
blue - 6.92V
second white - descent from about 6V to 0.8 in about a minute, similar reaction (drop in 2 minutes from 6V to 0.04V) when measuring the second white with blue.
When I shorted the wires, blue with green open the bolt and mass with green.
Currently I have set:
1 - orange (call works)
2 - mass (first white)
3 - second white (the loudspeaker in the handset works)
4 - blue (microphone in the handset - not working)
5 - installed jumper with 4 (bolt)
6 - green (bolt works)
