Connecting the intercom handset yourself, if necessary, is not at all difficult. You just need to know a few simple rules.

handset design

The subscriber apartment device consists of two parts. This is a handset and a panel that is usually mounted on the wall next to the front door. The tube can be installed anywhere, only you need to lay a wire around the apartment. Inside the handset are a microphone, a speaker and a small board with discrete elements. There is a handset removal lever on the panel, and on the handset itself there is a door opening button.

The electronic lock button can also be located on the wall panel. In modern models, the lever is replaced by a reed switch, and there is a small magnet on the tube itself. On some models, a handset switch may be installed. On the back of the panel are two screws marked "+" and "-". A two-wire line is connected to them.

Connect the wires to the intercom handset in accordance with the polarity, otherwise the system will not work.

All access intercoms installed in the entrances of apartment buildings are divided into two groups:

Based on the types of intercoms, apartment tubes also have slight differences. In coordinate intercoms, the switch installed in the entrance is responsible for the apartment number, and in digital devices, a special microcircuit, which is located on the board inside the handset.

Possible malfunctions of apartment tubes

An apartment intercom device (UKP) is a completely reliable device that can last for many years, but some defects may occur during operation.

The most common defects include the following:

• Mechanical damage to the tube
• When you pick up the handset, the call does not turn off the ringtone
• Lock button not working
• When the lock button is pressed, the call is dropped
• Poor hearing

The cost of a tube for an intercom starts with bran, therefore, with severe mechanical damage, it is easier to purchase a new device than to repair a broken or cracked case. When the call signal continues to sound when the handset is off-hook, there is no voice communication with the visitor and the electronic lock button does not work, this means that the off-hook switch is not working.

Free legal advice:

Many craftsmen repair it on their own, but if there is no appropriate tool and work experience, then it is better to invite a master.

If the electronic lock only works after a few clicks, then the microswitch is faulty. The door opening button can be located directly on the handset. In this case, the microswitch is soldered on the printed circuit board. You can replace it yourself. It is necessary to alternately warm up the four contacts with a soldering iron while wringing out the case with a flat screwdriver. It is enough just to change the button located on the main panel.

The reason for the call being dropped when the electronic lock button is pressed may be a broken wire coming from the speaker. If any malfunctions occur, you should first check the reliability of all solders in the tube, and the connection of the line to the lamella on the back of the wall unit. Poor hearing may be due to a defective microphone or speaker, as well as contamination of the "Balance" trimmer on the handset board. This potentiometer is not available in all models, but if it is installed, you can, remembering the position of the engine, rotate it left and right. In many cases, normal hearing is restored.

Intercom handset replacement

When installing an intercom on the entrance door of the entrance of an apartment building, all work is carried out by the masters of the corresponding organization. They also install residential intercoms.

Therefore, self-replacing the intercom handset comes down to a few simple steps:

Before buying a new handset, you should find out the type of intercom. Models designed for coordinate and digital intercoms have a design difference. The sales assistant will always tell you which subscriber handset is suitable for a particular intercom model.

If you plan to transfer the tube to another place, then the main thing is to observe the polarity when connecting. Only two wires are suitable for any subscriber device model, which are fixed with screws on the back side of the main panel.

If replacing the handset for a coordinate intercom requires only connecting wires, then installing a handset for a digital intercom includes dialing the apartment number. The body of the tube should be carefully opened. On the board, pins are numbered in a row, and so on. With the help of jumpers (jumpers), it is necessary to close the pairs of pins in such a way that the sum of the dialed digits is equal to the apartment number. So for apartment number 7, the first three pairs of pins should be closed.

Conclusion

Self-replacement of the intercom handset is quite possible even for a non-specialist. The main thing is to choose the right model for replacement and not to confuse the polarity of the connection.

How can I replace the intercom handset myself?

Increasingly, there is such a device as an intercom. They are installed in a private house or at the entrance to several apartments. The device becomes easy to use. But after long-term operation, like any other mechanism, it is possible that it will fail in operation. There are many reasons for this, and often, if a breakdown occurs, the device no longer opens the door of the apartments. If we consider equipment that is installed to work in several apartments, then their principle of operation is the same. There is an option that the owner of the premises opens the door after he sees his guest through the built-in video surveillance. But this option is popular not for apartments, but rather for private houses.

But whatever the device, it has a certain configuration:

1. Device for making a call;
2. Handset for negotiations;
3. Video monitoring;
4. Screen for displaying the image.

Apartment intercom Device with video surveillance

What device has a handset for negotiations?

The tube itself becomes the main element for the full operation of the intercom. It is installed exclusively inside the premises of apartments or houses. With the help of it, a person decides to open the premises to the one who calls or not. If we consider the basic configuration, then it is the same in any version. There are differences and they depend directly on the manufacturer of the system. Consider what is in the tube:

• Speaker for talking;
• Microphone for negotiations with the subscriber;
• Wires that perform a connecting role;
• Electrical board.

The main malfunctions that may occur with the speech tube

Attention! The handset in the system is the main working system on which the operation of the intercom depends.

Free legal advice:

If you use the device for a long time, then sooner or later the tube will break. The best option is to replace the broken tool. But often such a replacement is a costly affair. Therefore, you should first try to fix the problem. At the moment when the intercom stops working fully, the owner of the premises has a lot of inconvenience. Since at this moment he no longer has the opportunity to fully monitor the building and the door in this case opens without difficulty. When the device is installed on the entrance, and use is difficult in one apartment, then most likely the problem is in the installed tube. To deal with the trouble, consider the types of breakdowns:

• The intercom does not work due to the fact that the door open button does not work;
• Poor hearing of one of the parties;
• Cable break;
• Retraction of the tongue.

You can determine the cause of the trouble yourself. To do this, you need to have minimal technical knowledge. If there is no such knowledge, then a specialist is attracted to work.

Breakdowns that can be fixed

Can a push button switch be fixed?

The most common of all problems is the failure of the button. This seemingly insignificant detail significantly affects the entire repair of the intercom handset, as it has a direct connection with the switch located inside the device. If a problem occurs at the initial stage, crackling is heard, and then many notice that the intercom is phoning, and significantly.

When the caller presses the button, the crackle is heard distinctly. At the beginning of the problem, the door will open normally. But if you wait a little time and do not make an effort to repair it, then it will stop opening.

The switch itself cannot be repaired. Just buy a replacement part. Its cost is not high. If a professional is engaged in the matter, then everything will be done not only quickly, but also with high quality.

Open button stopped working

When guests come to a person and they call the intercom, a specific sound appears in the room, after which the owner of the room picks up the phone to clarify who came. But at the moment of pressing the button refuses to function. More often the switch, which is located under the button, becomes the fault. To understand the causes and repair in more detail, we remove the cover of the device and carefully study its “insides”.

In order to understand that in the place where the owner assumes, a new part is connected to the problem area for some time through the four-wire version of the system. Thus, through these 4 cables they deal with the problem that has appeared.

Hard to hear during a call

Attention! When such a problem occurs, from the beginning they pay attention to the correct volume setting, since someone could mistakenly reduce the volume of the speaker and create a problem without knowing it.

Pay attention to the speaker that the handset is equipped with. It is more often and becomes the reason that the subscriber is hard to hear. Inside the device has a special resistor that regulates the microphone and speaker. But you do not need to immediately turn down or turn up the volume level. From the beginning, remember the position in which the resistor was located and only then begin to twist it.

Aspects to consider when choosing replacement parts

Choosing the right part to replace becomes important in the repair process. Make purchases in special stores. In addition, pay attention to the intercom model for which parts are purchased.

Internal components of the device

Attention! After the repair, check the operation of the entire apparatus and look at how the door opens.

If we consider modern models that appear in the assortment, intercoms that do not have stands stand out. When choosing, consider the type. The differences between the proposed options may be as follows:

• Call addressing type;
• Mode of application;
• Features of functional work.

Problems in the acquisition and selection should not arise. Moreover, the range is full of various models. But still, it is better not to install the equipment yourself, but to turn to specialists for help. Of course, they will ask for a fee for their services, but you can be sure that everything will be done with high quality and with a long-term guarantee in service.

How to connect the intercom handset in your apartment yourself

The presence of an intercom has long been an indispensable condition for ensuring the comfort of a modern apartment. The main purpose of these devices is to enable homeowners to receive calls from visitors and open doors remotely. Intercoms have proven to be much more convenient than outdated combination locks. Let's find out how to connect the handset of the apartment intercom on your own.

Types of modern intercoms

For reliable identification of visitors, an audio or video intercom is used. The latter is more often installed in private cottages and was created for additional visual control of the space in front of the front door. As for urban apartments in high-rise buildings, they often install an audio option, the design of which includes the following elements:

• A handset that is equipped with buttons for accepting a call and opening an input electromagnetic or electromechanical lock. The device is installed by a company providing intercom installation and maintenance services. If such devices were not installed during the equipment of the entrance in some apartments, it is possible to install them yourself. You can also use the services of a specialist service company.

• Call panel equipped with a dial pad with numbers, which allows the visitor to signal the intercom handset by pressing the required code, usually the apartment number. In addition, there is a reader on the panel, with which you can use a special key to open an electromagnetic lock blocking the entrance doors.

• Locking device with power supply. The most common type of lock today is electromagnetic. Until recently, electromechanical latches equipped with sliding mechanisms were found everywhere. Such devices are often present in the entrances of apartment buildings even now. To operate the remote-controlled unit, you must use a constant voltage of 12 or 24 V.

• Switch. This device is designed to transmit a signal from the call panel to the subscriber handset of a particular apartment.

Depending on the type of signal processing, digital and analog intercoms are distinguished.

Important! Different types of receivers are used for digital and analog models. Before purchasing such a device, you should definitely find out what type is installed in the entrance.

Free legal advice:

Digital intercom

To connect devices of this type, only a cable with two cores is used, through which an encoded signal is transmitted. The handset installed in the apartment, the number of which was dialed on the call panel, responds to the signal. To set the correspondence between the dialed code and the handset, special jumpers are used - jumpers - which bridge the necessary contacts in the response device.

To correctly program the handset, the jumpers are placed between the numbered terminals so that the sum of the digits is equal to the apartment number.

The advantages of such intercoms include ease of installation and connection of new subscribers.

The main disadvantage of such equipment is the influence of each tube on the operation of the entire system. When replacing a device, which is carried out due to its breakdown, as well as when connecting new subscribers, the correct installation of jumpers is extremely important.

Attention! In the event of a digital tube connection error or a short circuit in the lead wires, the system may malfunction.

Free legal advice:

Currently, to partially eliminate this drawback, floor controllers are used, which allow localizing a malfunction within one level.

Another disadvantage of digital intercoms is their relative high cost, which does not allow these devices to be widely used.

Analog intercom

Analog installations use a coordinate matrix connection and work on the principle of a telephone exchange. An additional element of such a system is a switch, which processes and analyzes the signal, as well as redirects it to a specific subscriber.

Two buses are used to connect the intercom handset to the switch. Contacts of the first of them (D0–D9) correspond to tens, and the second (E0–E9) to units. Thus, in order to connect an intercom to an apartment, the number of which, for example, is 74, you need:

• connect the conductor from the positive terminal of the subscriber tube to the contact corresponding to the number 7 on the tens bus;
• the conductor adjacent to the negative terminal - to the contact corresponding to the number 4 on the unit bus.

In the considered connection option, a device designed to serve up to 100 subscribers was used. There are models that can work with a large number of numbers, but their principle of operation is no different from that discussed above.

Free legal advice:

If the numbers of the apartments located in the entrance do not allow connection, the installer reprograms the control panel with the numbers shifted by a certain number (for example, 84 must be subtracted from each). In this case, there is some difficulty in connecting, since without consulting a specialist who installed the intercom in the entrance, it is difficult to find out the amount of offset.

Connection order

The sequence of actions will be as follows:

1. At the first stage of work, the location of the intercom handset is selected, then it is fixed on the wall using quick installation.
2. Next, the installation location of the switch is determined (for analog intercoms). On each floor, they are installed in a junction box for low-current circuits. All of them are connected in parallel, which greatly simplifies the installation process. In the general case, only one switch per entrance is enough, however, when using such a scheme, it is necessary to stretch wires from the apartments of the upper floors to the installation site of the device.
3. After removing the protective cover of the switch, the terminals corresponding to tens and ones are determined, then the connection is made, so that the sum of the numbers of these contacts shows the serial number of the apartment.
4. Wires are connected to the tube. It is extremely important to respect the polarity. The positive terminal is connected to the contact of the switch corresponding to tens, the negative terminal - to units.

Important! If the polarity is not observed during the connection of the device of the coordinate matrix system, the operation of the devices of the entire entrance may be disrupted.

Thus, the installation of an intercom handset is not particularly difficult. However, before you start doing such work with your own hands, it is important to determine the type and brand of the device used, as well as the location of the switch and the connection diagram of subscribers.

Tip 7: How to fence off unwanted visitors at home and office: individual intercom

An individual intercom is suitable for apartments or offices with a separate entrance, or for a country house. In this case, it is worth considering whether you need a color intercom or a black and white intercom is enough. Their prices will vary accordingly. But first, let's figure it out - what does the intercom consist of?

How to open any intercom without a key ... Codes for intercoms. Save it, it will come in handy!

On VIZIT intercoms, to open the door, you need to program the key, and if the standard settings have not been changed, then # 4230 (you can # 423) and the door will open. Entering the intercom service mode is quite simple: Free legal advice:

Installing the intercom code yourself without hacking.

If necessary, you can change or turn off the individual apartment code without entering the service settings mode. This requires two people. The number of the corresponding apartment is dialed on the call block. After a call is received in the apartment, the UKP handset is removed. On the UKP, within 5 seconds, the button for opening the lock is pressed and released six times. Each time you press the button on the call block, the WAIT FOR ANSWER indicator should turn off and the ENTER indicator should turn on.

After the sixth press and release of the “open door” button on the control panel, the indicator DIAL APARTMENT NUMBER turns on in the call block, one signal sounds, confirming the readiness to record a new individual code, while the duplex communication mode is maintained.

On the call block, a new value of the individual code is dialed. The person dialing the individual code number must inform the tenant about the end of the code dialing. To record the value of an individual code in the memory of the call block, the tenant must press the “open door” button on the control panel, a signal sounds in the call block confirming the entry of the code, after which it is necessary to put the call receiver in the holder.

The subscriber handset or apartment intercom is an integral part of the intercom system. It is installed in each apartment of a residential building and allows you to communicate with the visitor and control the electronic lock to open the door. Connecting the intercom handset yourself, if necessary, is not at all difficult. You just need to know a few simple rules.

handset design

The subscriber apartment device consists of two parts. This is a handset and a panel that is usually mounted on the wall next to the front door. The tube can be installed anywhere, only you need to lay a wire around the apartment. Inside the handset are a microphone, a speaker and a small board with discrete elements. There is a handset removal lever on the panel, and on the handset itself there is a door opening button.

The electronic lock button can also be located on the wall panel. In modern models, the lever is replaced by a reed switch, and there is a small magnet on the tube itself. On some models, a handset switch may be installed. On the back of the panel are two screws marked "+" and "-". A two-wire line is connected to them.

Connect the wires to the intercom handset in accordance with the polarity, otherwise the system will not work.

All access intercoms installed in the entrances of apartment buildings are divided into two groups:

• Coordinate
• Digital

Based on the types of intercoms, apartment tubes also have slight differences. In coordinate intercoms, the switch installed in the entrance is responsible for the apartment number, and in digital devices, a special microcircuit, which is located on the board inside the handset.

Possible malfunctions of apartment tubes

Apartment intercom device(UKP) is a completely reliable device that can last for many years, but, during operation, may arise.

The most common defects include the following:

• Mechanical damage to the tube
• When you pick up the handset, the call does not turn off the ringtone
• Lock button not working
• When the lock button is pressed, the call is dropped
• Poor hearing

The cost of a handset for an intercom starts from 270-300 rubles, therefore, with strong mechanical damage, it is easier to purchase a new device than to repair a broken or cracked case. When the call signal continues to sound when the handset is off-hook, there is no voice communication with the visitor and the electronic lock button does not work, this means that the off-hook switch is not working.

Many craftsmen repair it on their own, but if there is no appropriate tool and work experience, then it is better to invite a master.

If the electronic lock only works after a few clicks, then the microswitch is faulty. The door opening button can be located directly on the handset. In this case, the microswitch is soldered on the printed circuit board. You can replace it yourself. It is necessary to alternately warm up the four contacts with a soldering iron while wringing out the case with a flat screwdriver. It is enough just to change the button located on the main panel.

Reason for dropping a call when you press the electronic lock button, there may be a break in the wire coming from the speaker. If any malfunctions occur, you should first check the reliability of all solders in the tube, and the connection of the line to the lamella on the back of the wall unit. Poor hearing may be due to a defective microphone or speaker, as well as contamination of the "Balance" trimmer on the handset board. This potentiometer is not available in all models, but if it is installed, you can, remembering the position of the engine, rotate it left and right. In many cases, normal hearing is restored.

Intercom handset replacement

When installing an intercom on the entrance door of the entrance of an apartment building, all work is carried out by the masters of the corresponding organization. They also install residential intercoms.

Therefore, self-replacing the intercom handset comes down to a few simple steps:

• Purchasing a new handset
• Installing it to replace the old one

If you plan to transfer the tube to another place, then the main thing is to observe the polarity when connecting. Only two wires are suitable for any subscriber device model, which are fixed with screws on the back side of the main panel.

If replacing the handset for a coordinate intercom requires only connecting wires, then installing a handset for a digital intercom includes dialing the apartment number. The body of the tube should be carefully opened. On the board, there are pins in a row numbered as 1-2-4-8 and so on. With the help of jumpers (jumpers), it is necessary to close the pairs of pins in such a way that the sum of the dialed digits is equal to the apartment number. So for apartment number 7, the first three pairs of pins should be closed.

Conclusion

Self-replacement of the intercom handset is quite possible even for a non-specialist. The main thing is to choose the right model for replacement and not to confuse the polarity of the connection.

In country houses and apartments, you can install inexpensive intercoms that will provide control of entrances to the entrance or premises. These systems differ from industrial systems in their simpler design and functionality within the declared cost. Due to the availability of home video surveillance and access control, it becomes necessary to decide how to connect the intercom handset in compliance with technical subtleties and security measures.

Design features of the equipment

To make the most of the system's capabilities, you need to delve into the main technical characteristics, understand the device and the operation of such equipment.

To do this, first of all, it should be understood that such devices provide the transmission of audio and video signals, guarantee blocking of entrance locks. The most famous devices are Vizit, Falcon Eye, Commax.

In an apartment building, the installation of such equipment is carried out centrally with the involvement of companies that know how to connect an intercom in an apartment, and provide such services for a fee. These same specialists are engaged in the maintenance of systems.

But if you plan to save money and do without contacting installers, then you need to get an idea about the set of intercom equipment, including the purpose and functionality of the following elements:

• a speech tube, which is installed indoors and allows you to answer the visitor's request (connected to the locking system);
• personal call panel for reading the code, entering numbers, displaying video information and transmitting sound;
• a locking device with an electromagnetic mechanism or older versions with a valve and an electric drive;
• a switch in the form of a module for transmitting signals in accordance with the dialed apartment number;
• power supply, buttons and switching parts.

Those who want to understand how to connect an intercom on their own should know that such a system powered by 12 or 24 V. In this case, you can choose options with the transmission of only audio or also video.

Installing an intercom of the selected type

For country houses and high-rise buildings, manufacturers offer intercoms of digital and coordinate-matrix type. Each of these options is approximately similar in terms of installation principle, but differs structurally and functionally.

In digital systems, the signal is transmitted through two-wire lines and controllers, which determine how to connect the intercom handset in the apartment. Separate interfaces for apartments are created using jumpers through signal transmission to the tube microcircuits.

Coordinate matrix devices are structurally simpler, which increases the fault tolerance and reliability of the entire system. In such equipment, the signal is transmitted from the coordinator to the handset in the apartment through the switch using wiring (one / ten) and the DAT1 signal. The initial information is processed by the modulator, and then a connection (LIN) is created with the selected apartment, and the corresponding signal is sent through the electromagnetic relay.

When installing digital and coordinate matrix systems, it is required compliance with security measures, which are the same in both cases:

1. Before you connect the intercom yourself in an apartment building, you should de-energize all the wiring with which you plan to work.
2. It is recommended to install only licensed products from trusted manufacturers that provide maintenance and warranty repairs for their products.
3. All components and electrical components must be installed in closed rooms or special containers with minimal humidity.

At the preparation stage and before connecting the intercom, choose the wiring that is suitable for the characteristics with length up to 25 - 50 m or more and core thickness up to 1.5 mm.

It is necessary to install digital and coordinate matrix intercoms with a connection to the mains, equipped with circuit breakers (16 A) or fuses (10 A), as well as a residual current device (30 mA). The transformers are connected to the intercom and to the network, and the handset is connected through the power cable to a regular outlet. For safe operation, you will need concealed electrical wiring, therefore, before connecting the intercom handset on your own, according to a pre-designed scheme, you need to fix the corrugated pipes.

Mounting the outer panel and tube

Intercom connection includes the installation of an outdoor panel, which must be located at a height of at least 1600 mm from the base. On the doors or the wall, linings are fixed for fixing the main components or strobes are made for built-in modules.

Then install and fix the equipment itself, connect the wiring. Connecting the intercom in the apartment is as follows:

• Make strobes for corrugated pipes.
• Fix the wiring and seal the strobes.
• Install the tube fasteners and connect it to the power supply.

The indoor installation height is at least one and a half meters from the floor. Transformer is better placed in a hard-to-reach and protected from moisture place and connect with a fuse.

The scheme of installation of video equipment is similar to the installation of conventional equipment. Some features apply only to the installation of a video camera, which should not be directed to sunlight or strong light.

It will take and vibration protection, actions of vandals or mechanical damage from any other external influences. Before you connect the intercom in the apartment, you need to take care that the video camera is not affected by high temperatures (above +40 ºC).

It is quite possible to independently mount an intercom system if you have at least basic skills and abilities to work with electrical wiring and such equipment. Do not interfere preliminary consultations of experienced specialists and work under the constant supervision of a master who deals with such work professionally.

We have all heard the expression: “My house is my fortress!”. It is not surprising that in each house an access intercom and a reliable door are installed. But even in a fortress, not everything is reliable, and, at one not-so-great moment, the intercom handset stops working. In such a situation, as a rule, there is no need to replace the intercom (the price is different). In 9 out of 10 cases, the problem is fixed with a repair.

An energy-intensive (and free) solution for such a situation is to constantly call expected visitors by phone, and then go down to the entrance door to manually open it. But the easiest and most convenient option is to simply repair the intercom handset in order to comfortably manage access.

Why intercom tubes break

There are various reasons why the intercom handset fails:

1. From old age. In old houses, the installation of an intercom and the installation of an intercom handset in an apartment (the price of equipment and installation was high) was carried out in the 2000s. Over the decades, the equipment has become obsolete and has repeatedly exceeded its service life.
2. Physical impact (shock or moisture). Although intercom handsets are made in a durable case, there are situations when they still break. For example, when moving into the house, they brought furniture and accidentally hit the intercom handset with a heavy sofa, or maybe water got inside the handset and closed all the contacts. Over the years, we have faced various situations.
3. Incompetent fitters. It also happens that the neighbors had a poor-quality installation of an intercom in the apartment (the price for the neighbors was minimal), and your equipment failed.
4. Manufacturing defects. Sometimes the handset stops working for no apparent reason. And the thing is that the factory soldered poorly or got garbage, which eventually closed the circuits of the board.

Intercom handset installationin the apartment price

Before proceeding with the installation work, it is necessary to understand the type of equipment used. The handsets of intercoms differ from each other in the circuit diagram of communication. There are currently two such schemes:

1. Digital. Progressive connection scheme, in which all intercom handsets are connected to one low-voltage line (5-8 V). Each handset is assigned a specific address (code). A specialist installer (adjuster) sets the jumpers of the central board to a certain position.

The complexity of this method lies in the fact that there is no single programming standard and each manufacturer implements it differently. This requires extensive knowledge of working with equipment from different manufacturers. If the intercom is incorrectly configured and installed in the house, the price of such an error is the inability of all residents of the entrance to use the intercom.

1. Coordinate. Classic connection model. In it, each handset has a separate pair of wires leading to the switch (this device connects different lines, depending on the called subscriber). The use of a switch imposes restrictions on the number of subscribers, there cannot be more than 99.

In such a scheme, it is extremely important to make the correct connection and configuration. Errors will lead to the complete inoperability of the intercom. For a correct connection, the installer must connect the wires to the tube according to polarity. Both schemes are popular. Installation of an intercom (the price in both cases is approximately the same) is carried out as soon as possible. Let's return to the problem of a non-working intercom handset. Before throwing away the old tube and replacing it with a new one, it is wise to find out if it can be repaired. This will be beneficial, because repairing an old tube is cheaper than buying a new one. However, you should not worry about the costs if you need to replace the intercom handset in the apartment, the price, as a rule, does not exceed 1500 rubles.
