Connecting an intercom handset. The Vizit intercom circuit will help in installing equipment

Today, it is important to ensure the safety of your home. Old, difficult-to-open locks have been replaced by new ones. modern device– an intercom that not only ensures the security of your home, but also allows you to remotely control the lock on the door or gate. This device is widely used in apartment buildings, in private homes, cottages, large offices and warehouses. In most cases, intercoms are installed by special companies that sell them. But since this equipment is simple in structure, you can easily install it yourself. In this case, the problem arises in the solution - how to connect the intercom handset. As practice shows, everything is very simple.

What is an intercom handset?

The intercom handset is one of the components of the intercom protective system, which provides communication between the owner and those wishing to enter the premises. If the external communication element is a calling panel located outside, then the handset is a home appliance that is installed inside the protected premises. Such a tube can be installed either independently or by calling a special team.

In most cases, the handset provides communication immediately upon picking it up, without the need to press any combinations. Installation of the tube usually falls on the shoulders of professionals.

Each type protective agent requires a specific handset because different devices you need to lay a certain number of wires.

If you are using a digital intercom, then in this case you will need one cable that is laid from the digital panel. Using its individual branches, it connects to each individual apartment. If a coordinate matrix type intercom is installed in the house, then the installation involves laying wires equal to the number of apartments in the entrance.

How to connect all device components?

Sooner or later, each of us will face the problem of connecting the tube. There may be a number of reasons for this:

Installation of equipment independently in connection with the installation of a protection system;
Connection of the tube due to a breakdown of the previously installed one.

If you still have to do this work yourself, then first of all you should purchase completely new equipment. IN in this case One should take into account the fact that the handset must fully comply with the installed intercom system.

Today, buying a handset for an intercom is not difficult, and you can safely purchase it yourself. Thanks to the many modern companies engaged in this production, there is a wide range of products that are publicly available and suitable for any type of intercom. It is strongly recommended to purchase the product only from official dealers, which guarantee the quality of the product and provide a guarantee for long term services.

The device must meet all the specified quality conditions, since only high-quality intercom handsets can ensure uninterrupted and reliable operation protection systems. Otherwise, re-installation will not take long.

Installation of handsets for digital intercoms

Digital intercom systems are mainly used in apartment buildings. Installing a handset of this type has its own specifics, namely: this addressing scheme requires a two-core cable to which the subscriber handset is attached. Here you should pay attention to the polarity.

Tube connection plan

The installation of the intercom handset in this case has its own microcircuit, which is programmed with jumpers or jumpers for each apartment number. In this regard, in order to find out your apartment number, you will have to carefully disassemble the handset and carefully examine the existing microcircuit. Near each jumper there is a special digital panel on which the numbers are in ascending order. Here the apartment code is made up of numbers related to closed jumpers.

A disassembled old handset can serve as an example from which you can transfer the code to a new device. Thus, installing a new tube will not be difficult.

Installation of the device on a coordinate matrix type intercom

Connect the intercom handset yourself to this type won't be difficult. Here, all the work consists of transmitting a signal to a special switch, which, when a call is received, processes it and, due to the presence of special keys, sends the call signal to the required subscriber device.

Installing a handset for such an intercom will force the owner not only to work hard, but also to develop quick ingenuity. During installation, the whole problem lies in the cable, which is divided into many wires related to each individual apartment in the entrance. It should also be taken into account here that tens keys generally do not exceed seven, including zero. Thus, the total number of users can be more than eighty.

Do-it-yourself installation of an intercom handset consists of searching the desired tire tens, as well as units. It is very easy to deal with dozens - they are located on the panel of the required floor. All that is required is to find the wire to which the wires related to each apartment in the entrance are connected. This way you will select the cable you need.

To select the correct unit bus, you need to go up to the floor with the apartment number that matches the last digit of your apartment, and again find the cable on the panel. A plus is connected to the tens bus, and a minus to the units bus. This is where all the difficulties end. Installing the device is not difficult.

When connecting an intercom, people often wonder: what to do if you connected the device yourself, but it doesn’t work? The answer is simple: you should reconsider the device assembly diagram, and also pay attention to the polarity, since it is with polarity that the most problems arise.

If you doubt the correctness of the work done, call a special specialist to your home. Such masters usually provide their services to all companies involved in the sale and installation of intercoms.

Previously, the device was a simple intercom with a call button (buttons). The intercom circuit for 8 subscribers is shown below.

It is a simple amplifier with a microphone input. The call remote control is a simple switch through which one or another subscriber is connected. The response block (each subscriber has its own) is built according to the same scheme.

Modern industrial intercoms have more complex circuit and perform additional useful functions:

Open the lock (magnetic);
Allows you to see the caller (built-in screen);
Help organize video surveillance;
Protect the house.

The call panel is installed using two methods:

attaches directly to the wall near the door or to the door with dowels and screws;
mounted on a metal panel and clamped with screws reverse side. The metal is drilled, and the entire structure is installed on the wall or door using screws and dowels.

The video peephole should be fixed strictly in the middle of the door, approximately at head level. If you had a simple peephole installed, then it should be removed and the hole should be drilled to the diameter of the new observation device. Then we drill holes for plastic fasteners, install and insert the wire into them.

2. Connection of several residents.

In modern entrances, special conversational devices are most often installed as access devices. They allow you to protect your safety and the safety of your property. Connection Vizit intercom(Visit), Falcon Eye, Commax (Commax) and Metacom are most often performed by special service companies, but this can also be done with your own hands.

Intercom design

An intercom is a device that allows someone to enter a room or, conversely, deny entry without direct contact with him. The device has gained particular popularity literally in the last decade; previously, it was most often used to protect front doors. combination locks.

An intercom in an apartment or private house consists of a handset, a calling panel, video equipment (if additional connection for monitoring a door or gate is required), a lock and a switch. Let's consider functions of each part:

As an additional security feature, the call can also be supplemented with the ability to connect a video intercom (Kenwei KW-4HPTN, Kocom KCV-A374SD). In this case, all data is transmitted using the camera to a special TV or computer. Unlike an audio intercom, a video system is more reliable in use, because in addition to making a call, visitors are also visually monitored.

Types of intercoms

There are several types of intercoms that are used to protect against uninvited guests apartment or private building. Their connection varies depending on the type:

Digital (Eplutus EP-2297C, Gardi GRD, Hyundai HA-201);
Coordinate matrix (AVC-305, Commax CDV-DPV-43 MTN, Laskomex).

Digital They work on the following principle: when making a call, they transmit a signal over a two-wire line, in which the number of the connected apartment is recognized. In this case, so-called jumpers are used for pairing, which transmit signals through a twisted grid to a specific handset. Each tube, in turn, is equipped with microcircuits. It is very convenient that you can connect all apartments not only in the entrance to such a controller, but also on a specific floor.

Intercom connection diagram coordinate matrix type simpler and more reliable, therefore it is more popular. A switch is connected to the coordinate communication device, which switches the signal to a specific handset when calling. The connection is made using wires of tens and ones, i.e., each apartment is designated by two cables, the numbers of which are not repeated. To establish communication, the signal is sent through the DAT1 line to the switch. After this, the modulator transforms and processes the received information and connects to one specific “Unit” and one “Ten”. Afterwards, thanks to an electromagnetic relay, a connection is made to a specific apartment via a LIN telephone line.

Most often, such a connection is parallel, which greatly facilitates self-installation. The only thing you need to remember is the polarity of the intercom calling panel, electric lock and apartment handset. If electrical connection is performed incorrectly, the operation of not only a specific subscriber, but also the entire security system is disrupted.

Rules for installing VIZIT intercoms

Connection

Step-by-step instructions on how to independently connect the Eltis, Cyfral (Digital) video intercom with the z 5r controller:

You can connect a key reader (touch memory) or a buzzer, a button that will be used to open an electromechanical lock, a backlight, the lock itself and a power supply to this controller;
The buzzer and door sensor are optional parts, while the operation of the entire system depends on the door open button and power supply. If necessary, a screen can also be installed; optical control can be carried out through the monitor;
To connect the board, a terminal block is most often used, the contacts of which are connected to necessary wires networks;
Then simply connect all the necessary wires to apartment tube and check that the polarity is correct.

Domestic intercom models are also very popular, in particular the KS-2006. To connect them, schemes with two switches, one connection module, for several subscribers, etc. can be used.

What to do if the Faktorial or Eltis intercom is disconnected from the power supply:

Prices for repairs or installation of intercom systems may vary depending on the city and the specific company. On average, the price of connecting an intercom varies between 200–500 rubles (the price is indicated only for the work, without the price list for the wires used). For example, connect calling panel MVK-325 UKP in Moscow and St. Petersburg will cost 500 rubles.

Today, not only complex video surveillance systems are used as security devices, but also budget intercoms. The intercom allows you to control the entrance to the entrance and limit access to the high-rise building to strangers. The meaning of the device is as follows:

the guest dials the number of the apartment he needs to get into on the code display and waits for an answer;
a signal sounds in the apartment, the tenant can check by telephone who is calling;
if deemed necessary, the door is opened; if not, no one can enter the entrance.

Intercoms have quickly replaced unreliable combination locks, but you still need to know how to connect them. Independent skills in connecting an intercom handset in an apartment will help you save money on calling a technician.

Types of popular intercoms

An intercom equipped with video and audio format is the most reliable. It makes sense to install a video device in country houses, it becomes possible to verify who is behind the gate. The well-known audio intercom installed in high-rise buildings includes the following functional components:

Handset - with buttons for receiving a signal and opening an incoming electromagnetic or mechanical lock. The apartment owner can refuse to install the tube and do it himself.
A call panel on which there is a display with buttons and drawn numbers. An electromagnet is also located here, allowing you to open the door through the use of entrance doors.
A locking part with a power supply, most often electromagnetic. In order for the lock to function, it is necessary to conduct electrical wiring with a voltage of 12 or 24 V.
Switchboard - is responsible for transferring a call from a panel on the street to the handset of a resident of a house or apartment.

How to connect a digital intercom handset

If the intercom is digital, you need to use two wires that transmit the signal to a specific apartment. During the transfer of information, there should be a correspondence between the call panel and the handset. To do this, use jumpers, which are called jumpers - they bridge the contacts in the response device.

Don't forget about these requirements:

For correct connection intercom tubes in the apartment, place jumpers between the numbered contacts.
Make sure that the set of numbers is equal to the apartment number in the house.

Among the advantages of digital units installed in high-rise buildings, experts note:

ease of installation;
possibility of connecting individual subscribers.

Disadvantages include the impact on a single security system everyone subscriber handsets. If there is a need to replace at least one failed device, the jumpers must be set again.

If the installation is carried out incorrectly, a short circuit may occur, causing the intercom to stop responding to the keys of apartment residents or to prevent incoming calls. Floor controllers can correct the situation; it makes sense to use them if the fault is associated with one floor.

What is the difference between connecting an analog intercom?

Analogue systems mean a telephone exchange, at least their work is very similar. Plus, a switch is attached to the device, which is responsible for processing and analyzing the call, after which it’s a matter of redirecting the signal to the desired apartment.

To correctly connect the analogue intercom handset in an apartment, repeat these steps:

Take two tires, one of which corresponds to tens, and the second to units. What does this mean? Let’s say a guest dials apartment 56 on the display, which means the positive terminal contact is first connected to the fifth number on the tens bus, and the negative terminal is fixed to number 6, located on the ones bus.
To do this quickly, you will need special equipment that can serve at least 100 subscribers of a high-rise building at once.
If the numbering of apartments does not allow you to connect the handset to the intercom in this way, experts recommend taking into account the possibility of reprogramming the control panel taking into account the shift of numbers by a certain number, for example, subtracting the number 55 from each number. Only an experienced installer can accurately record the amount of shift.

Guide to connecting any type of intercom

Generally step-by-step instruction Connecting an intercom handset has the following steps:

Determine which area is best to place the tube, fix the part on the wall using the quick installation technique.
Decide on the area where the switch will be fixed (if we're talking about about an analog device). The devices are placed in a distribution block designed for low-current circuits and connected in parallel. For the entrance, it is enough to arm yourself with just one switch, but be prepared to stretch wires from apartments located on upper floors, directly to the product installation site.
Once the protective cover is removed, proceed to identify the pins that match the ones and tens. Connect.
When connecting wires to the tube, remember the polarity. The terminal with a plus sign goes to the commutator contact, which refers to tens, and the minus sign suggests units.

From year to year we regularly paid the monthly fee for the intercom, and everything was fine. But then the intercom operators suddenly decided that they were the smartest and pretended that there had been no payment for the last six months.

Residents who still had receipts ran to prove the fact of payment. But I don’t even have receipts. I paid via the Internet. Of course, I tried to print something out there and show it to someone, but... they either don’t hear or don’t want to hear. In the end, I got tired of everything, and I decided not to pay until they sorted it out themselves.

And then one day a friend calls me and tells me that my intercom doesn’t work (it just doesn’t ring into the apartment). When you try to dial a number, everything is reset, an error signal sounds and “Err” appears on the indicator.

I came to the conclusion that there can only be one reason for this - these are the intercom operators in an original way they turn off the intercom for non-payment (they can do this for one apartment).

In general, of course, there may be other reasons, but I know exactly why my intercom doesn’t work. Apparently they think I have to pay for the same service twice.

Interestingly, I was still able to enter the entrance using my set of keys. You can't just open the door by pressing a button on the handset. If guests come, you have to go downstairs and open it manually.

It is clear that in this situation it makes no sense to contact a company that services the intercom. I had to figure out for myself how it turns on.

Let's first determine why the intercom may not work:

The call to your apartment has been disconnected (an error sounds when dialing the apartment number). You cannot call from the street and, accordingly, you cannot open front door by pressing a button in your apartment. The most common option.
We have deleted your keys from the intercom memory. In this case, you cannot get into the entrance using your tablet keys. The other residents' keys work as always. This is not usually done, but there have been cases.
Any technical malfunctions of the units, wire breaks (intentional or not), acts of vandalism, etc. These cases are always very individual and will not be discussed in this article.

Let's see what can be done using the Visit intercom as an example.

If the call to your apartment does not go through

Most likely, the so-called “intercom mafia” did this to force you to pay for a previously imposed service. They do this without entering the entrance, changing the intercom settings using the master key.

But, fortunately, this is easily fixable.

So, to connect a disconnected Vizit intercom, proceed as follows.

That's all!

We make sure that the intercom was able to be unlocked (calling to the apartment works), and return the jumper on the ECU board to its place. Otherwise, the intercom operators will ignore your manipulations and come up with some other trick.

Once again, without further comment. To turn on the call, dial:

#999 1 8 00# 1 *

Instead of 00 you need to substitute your apartment number. Then return the jumper to the “WORK” mode, close the lid and quietly leave.

What to do if the key does not work

These are again the tricks of the “intercom mafia.” They simply erase information about your keys from the intercom and that’s it.

The problem can be solved in two ways:

ask your neighbors for one of the keys and go make a couple of copies for yourself and your family members. The city is full of craftsmen providing this service. Advantage this method the fact that you will never be disconnected again;
record all your keys into the intercom memory again. To do this, you will again need access to the control unit (ECU) in order to switch it to programming mode (read how this is done a little higher).

Regardless of which method you choose, we proceed as follows.

We open the ECU, put the jumper in the PRG position, go down and switch the intercom to the service settings mode:

#999 (the signal will sound twice) 1 (single beep) 3 (squeak again) APARTMENT NUMBER#

After the apartment number and hash have been entered (if the number is 3-digit, then you do not need to press the hash), a single signal should sound. This means that everything is OK, the memory is free and ready to write the key. If you hear four beeps in a row and the word lights up on the indicator "FULL"- this means that you won’t be able to write down the keys; you will have to clear the memory first.

After a single beep, place your key on the reader. You should hear a double squeak and see the inscription on the indicator "YES". This means your key has been successfully written into memory. We apply the next key, then the next one, etc.
When you run out of keys, be sure to press the asterisk * (this is so that all settings are saved). And also be sure to return the jumper back to hide traces of tampering.

You can add another key in the same way. Let's say you want your friend to be able to freely enter the entrance using the key to his Visit intercom. In this case, you can simply enter the key recording mode as described above and add its key. All previously recorded keys will be saved (i.e., you do not need to record all the keys from the very beginning each time).

As you can see, there is nothing easier than connecting an intercom yourself that was disconnected for non-payment. Just download the instructions () and carefully read what is written there. For example, you can set your own individual code that will open the intercom without a key. Or you can write down your own master key so that you don’t have to go into the box and rearrange jumpers on the board every time :)

P.S. Am I the only one who finds it strange that our entire house has to pay someone for some mythical service? For example, I have never seen anyone do any work with our intercom (well, lubricate something, adjust it, paint it).

And the strangest thing is that some sharazhka office considers itself the right to prevent people from getting to their home. I also don’t understand on what basis they even interfere with the operation of the intercom? It belongs to the residents of our building, we bought it with our own money, so there’s no need to stick your fingers into it.
