How to change the intercom handset in an apartment yourself. Self-connection of an intercom: description and diagram

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. Connecting the intercom Vizit (Visit), Falcon Eye, Commax (Commax) and Metacom is most often carried out by special service companies, but this can 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:

1. Digital (Eplutus EP-2297C, Gardi GRD, Hyundai HA-201);
2. 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 in this case For pairing, so-called jumpers are used, which transmit signals through a twisted network 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.

Connection

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

1. 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;
2. 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;
3. To connect the board, a terminal block is most often used, the contacts of which are connected to necessary wires networks;
4. 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 Factorial 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, connecting the MVK-325 UKP calling panel in Moscow and St. Petersburg will cost 500 rubles.

Quite often, comfortable and well-equipped housing depends on how well utilities and service companies work. Even work such as connecting an intercom requires the participation of a third party. As a rule, even those residents who do not have technical knowledge can figure out how to install the tube.

Many modern city residents have more than once installed a telephone or Internet cable into their apartment. Installing an intercom handset is not much more difficult: it is enough to have access to the panel in the entrance and the switchboard. Most of the circuits used by today's companies are standard, and therefore understanding them and installing a handset at home is not difficult.

How to choose a suitable intercom handset?

By coincidence, it may turn out that in the entrance apartment building If there is an intercom, the handset itself will not be in the apartment. The previous owners could have dismantled it, or they simply did not pay for this service.

When control systems had just begun to appear on the market, there were not many service companies. Now their number has increased, but with the quality of services potential client may be wrong. Standard tubes that are installed in an apartment are not at all unique - you can buy them in technical or hardware stores. Before buying, you should check on what principle the intercom in the house works: usually there are two of them - digital or analog. You can find out this from your neighbors who also connected the handset themselves or call a service company.

According to the system, a handset for a digital or analogue intercom is selected. Externally and in price, they will not differ in any way, only the latter are more common, and accordingly, the connection diagrams will be different. The cost of a tube, with a variety of colors and shapes, can vary from 500 to 1500 rubles.

Digital connection

Now that an analogue or digital handset has been purchased for an apartment, it must be connected correctly, otherwise there is a risk of leaving the residents of the entire entrance without communication. It is not difficult to install the device in the most convenient place in the apartment; dowels and other fastening materials should be included. Next, you should understand the principle of operation of the system.

The market offers more handsets for digital systems, while homes usually have analogue ones. In order to connect an intercom using the digital operating principle of the system, you will need to program the handset itself. First you need to disassemble it. In addition to the wires to the electrical network, the installer will need jumpers with numbers located in the upper right corner. If you add them all up, you get the number 255 - this is maximum number handsets that can connect via this system.

The trick is that with the help of these jumpers you need to “assemble” the correct apartment number. For example, if you need to connect an intercom in an apartment with number 37, close the jumpers with the values ​​32, 4, 1. When added, these numbers add up to the desired number. Accordingly, when changing the number in the apartment, the jumpers should be reconnected.

The photo shows the internal circuit board of the tube

Then power is connected to the handset (the source must be taken care of in advance, at least 220 volts), and the two-core wire is laid to the intercom, that is, to the coiled cable in the panel on landing. Usually the required cable is easy to find out; you just need to trace where the same wires go from neighboring apartments. As a rule, they are held together with electrical tape. Connect according to the polarity markers, otherwise the circuit will not work.

Connection via analogue system

If in management company They reported that the intercom in the entrance was connected using an analogue principle, but when disassembling the tube, no jumpers were found - the equipment would have to be connected using a coordinate matrix system. Compared to digital, it is considered outdated, however, when used, it produces fewer failures with fatal consequences. If we take into account that up to 70 apartments can be located in the entrance of an ordinary high-rise building, then working on such a system is completely justified.

For a more detailed analysis, the following diagram is proposed:

• Call block (itself calling panel, which is most likely located on the street);
• Switchboard (a small communications center that should be located on the ground floor).

Tube connection plan

It is from the switch that two twisted pair cables (the same way a landline telephone is connected) go throughout the house. As a rule, the installation company is responsible for laying the cable in the entrance; you only need to connect the wires from your pipe yourself, and for this you will again need a shield.

Among all the small boxes you need to find one from which two or three cables come, depending on how the apartments are located on the floor. Let’s say there are four apartments on one site with numbers 78, 79, 80, 81. Accordingly, there should be three cables in the box. Now the correct connection of the intercom depends only on personal care: you need to figure out which bus the wires from neighboring apartments go to and also connect your own to them, observing the polarity. A plus is connected to the tens bus, and a minus to the units bus.

Whenever possible, the results of DIY work should be constantly checked. If one of the neighbors finds out that the tenant or owner is connecting to the system on their own, then problems may arise, followed by financial proceedings.

Practical recommendations from specialists when performing work:

• An analog system in the house allows you to install several intercom handsets in one room. This will be relevant for communal apartments, where each room has its own owner. To do this yourself, you just need to connect additional tubes, but come up with numbers for them that do not exist in this entrance;
• It may also happen that after connecting the intercom yourself, the system refuses to work correctly. If after several checks a positive result is not achieved, then the problem is in the programmed circuit. You won’t be able to change its data yourself; to do this you need to invite a specialist from service center. Before this, it is advisable to return the arrangement of the wires in the panel to its original state;
• There is no need to install the entire system - there are specialists for this. However, during subsequent maintenance you can save a lot if you understand the connection diagrams correctly.

As you can see, installing an intercom in an apartment is not at all difficult. If desired, the user can install a personal handset with a video monitor, but this will require more serious practical skills.

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. Connecting the intercom Vizit (Visit), Falcon Eye, Commax (Commax) and Metacom is most often carried out by special service companies, but this can be done with your own hands.

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.

In the photo you see an image of an audio intercom tube

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 this case, you 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.

Intercom installation diagram

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.

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:

1. 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.
2. 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.
3. 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.
4. 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:

1. For correct connection intercom tubes in the apartment, place jumpers between the numbered contacts.
2. 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:

1. Take two tires, one of which corresponds to tens, and the second to ones. 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.
2. To do this quickly, you will need special equipment that can serve at least 100 subscribers of a high-rise building at once.
3. 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:

1. Determine which area is best to place the tube, fix the part on the wall using the quick installation technique.
2. 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.
3. Once the protective cover is removed, proceed to identify the pins that match the ones and tens. Connect.
4. 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.
