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 similar situation- constantly call up by phone with the expected visitors, and then go down to the entrance door to manually open it. But the simplest and convenient option- just repair the intercom handset in order to comfortably manage access.
Why intercom tubes break
Exist different reasons, by which the intercom handset fails:
Intercom handset installationin the apartment price
Before proceeding to installation work, it is necessary to understand the type of equipment used. Intercom handsets differ from each other circuit diagram connections. There are currently two such schemes:
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.
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 correct connection the installer must connect the wires to the tube according to the polarity. Both schemes are popular. Installation of an intercom (the price in both cases is approximately the same) is carried out in 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.

Today, it is important to ensure the safety of your home. The old, hard-to-open locks have been replaced by a new one. modern device- intercom, which 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 dwellings, cottages, large offices and warehouses. In most cases, intercoms are installed by special companies involved in their implementation. But since this equipment- simple in structure, you can easily install it yourself. In this case, the problem arises in the decision - how to connect the intercom handset. As practice shows, everything is very simple.
The handset for the intercom is one of the components of the intercom of the security system, which provides communication between the owner and those who want to get into the room. 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 mounted either independently or by calling a special team.
In most cases, the handset provides communication immediately after picking it up, without the need to press any combinations. Tube installation usually falls on the shoulders of professionals.

Each type protective agent requires a specific handset, because for different devices you need to lay a certain number of wires.
If a digital intercom is used, then in this case you will need one cable, which is laid from the digital panel. With the help of its individual branches, it is connected 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.
Sooner or later, each of us will face the problem of connecting the handset. There may be a number of reasons for this:
If you still have to do this work yourself, then first of all you should purchase completely new equipment. IN this case take into account the fact that the handset must fully comply with the installed intercom system.

To date, buying a handset for an intercom is not difficult, and you can safely buy it yourself. Thanks to the many modern companies involved 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 goods only from authorized dealers, who guarantee the quality of the goods and provide a guarantee for a long service life.
The device must meet all the quality conditions set, since only high-quality intercom handsets can ensure uninterrupted and reliable operation of the protection system. Otherwise, re-installation will not keep you waiting.
Digital intercom systems are mainly used in apartment buildings. Installing a handset of this type has its own specifics, namely: such an addressing scheme requires a two-core cable to which a subscriber handset is attached. Here you should pay attention to the polarity.
Tubing 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 the number of your apartment, 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 pipe can serve as an example from which you can transfer the code to a new device. Thus, the installation of a new tube will not be difficult.
Connecting the intercom handset yourself to this type is not difficult. Here, all the work consists in transmitting a signal to a special switch, which, upon receiving a call, processes it, and, due to the presence of special keys, sends a call signal to the required subscriber device.
Installing a handset for such an intercom will make the owner not only work hard, but also develop a quick wit. 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 the 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 in finding the right tire for dozens, as well as units. It is very easy to deal with dozens - they are located on the shield 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.
In order to choose the right 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 shield. A plus is connected to the tens bus, and a minus is connected to the ones bus. This is where all the difficulties end. Installation of the device is not difficult.
You can learn interesting information about intercoms by watching this video:
When connecting an intercom, people often ask themselves the question: what to do if you connected the device yourself, but it does not work? The answer is simple: you should reconsider the assembly scheme of the device, and also pay attention to the polarity, since it is with the polarity that the most problems arise.
If you doubt the correctness of the work done, call a special master at home. Such masters usually provide their services in all companies involved in the implementation and installation of intercoms.
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.
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 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. WITH reverse side panel there 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 entrances 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.
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:
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 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 malfunction occurs, you should first check the reliability of all soldering in the tube, and connect the line to the lamella on the back side wall block. 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.
When installing an intercom on the entrance door of the entrance apartment building, all work is carried out by the masters of the respective organization. They also install residential intercoms.
That's why self-replacement 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, 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.
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.
Surely, this question was asked by almost everyone who dealt with the installation of an intercom system in their entrance. Maybe someone even went through this process completely - with a successful result, or a complete failure.
Even a functioning system cannot become a 100% guarantee that you will not again encounter a solution to the problem of how to connect the intercom handset. If your intercom system needs to replace the intercom handset, you need to purchase a new one. working equipment. At the same time, it is important to remember one point: the subscriber handset must correspond to the type of addressing of the call signal of the access intercom. This circumstance will also affect how the intercom handset will be connected and installed in the apartment.
They are widely used in apartment buildings, so let's consider the specifics of the process of introducing a new element - the intercom handset. With this addressing scheme, a two-core cable is used, to which subscriber tubes are connected in parallel. Polarity is the most important requirement.
When connecting the intercom handset in the apartment, it is worth remembering that each subscriber device is equipped with a microcircuit. It is programmed by jumpers, or jumpers, to a specific apartment number. Therefore, in order to find out the apartment code, you will have to disassemble the handset and carefully examine the microcircuit. Opposite each jumper, you can see a special panel with numbers arranged in ascending order: each of them represents a positive power of the number "2". The apartment code will consist of numbers corresponding to closed jumpers. Having the old handset disassembled in front of you, you can use it as a template for transferring data to a new device. Following these recommendations, you will immediately understand how to change the intercom handset.
Let's consider this case in detail. The operation of such a system is carried out by transmitting a signal to the switch, which, having processed the incoming call, connects the desired subscriber device with the help of keys. Installation often requires the owner not only quite a lot of time, but also ingenuity. After all, a multi-core cable goes from the switch to the tubes in the apartments, which is divided into wires of tens and units. The tens keys of a standard device do not exceed seven, including 0. Thus, the number of connected subscribers cannot exceed 80. In order to install an intercom handset, it is necessary to find the tens and ones buses. The first one is found quite easily - in the shield on your floor you find a wire to which as many cables are connected, as many apartments with the same first or first digits in the number are located on landing. To find the unit bus, go up to the floor where there is an apartment with a number that matches your last digit, and again examine the cables in the shield. We connect a plus to the tens bus, and a minus to the units bus. Now you can check your device. If you follow these rules, installing an intercom handset in an apartment will be very simple.
After reviewing this article, you learned not only how to replace the intercom handset. Now, if necessary, you can quickly, without material loss, bring the device into working condition, because you know all the secrets.
By installing an intercom, residents are waiting for an increase in the level of security and comfort. Agree, this useful device limits unwanted access to your territory, successfully complementing a reliable front door or gate. The function of audio or video communication that appeared after installation will not be superfluous, which is especially practical and useful for residents of apartment buildings. In the installation of all constituent parts there is nothing complicated, so resorting to the services of specialists is not so important. This article will help to verify this, in which we described how to install and connect an intercom with an electromagnetic lock.
The main elements of the access system are:
The auxiliary part is the connecting part.
First, let's deal with the installation of the main parts of the system, and then proceed to the installation and wiring. To understand what will be discussed further, we turn to visual diagram intercom in a private house:
Let us first analyze the installation of its elements indoors. Namely, the conversational handset (No. 1) and the power supply (No. 2).
From it it is clear that the intercom is connected by two wires. As a connecting cable, you can use a telephone two-wire wire or twisted pair.
On this, the work on installing equipment inside the premises is over - we move on to the street. Here we have to install an electric lock and a calling device.
In real life it will look like this:
A few words about connection. It is much easier to mount the wires if the installation of the system is known at the design stage. Then all the control and power lines are neatly hidden inside the walls, without violating the aesthetics of the room. Otherwise, in order not to ditch the walls, the cable is hidden in.
The video below clearly shows the procedure for installing and connecting an intercom system in a private house:
The video intercom is attached in the same way as the voice tube - in a convenient place for communication. Additionally, you will need to install a video camera near the entrance to the room or area. But to connect it, you need to use a circuit that uses 4 wires, and not 2, as with an audio tube. Let's consider it:
As you can see, the cores are responsible for powering and transmitting audio and video signals. The wire responsible for video transmission is braided to reduce interference and interference from nearby power wires. To connect a video intercom with your own hands, you can use the KVK P 2 2x0.75 cable. It would also be useful to look into the instructions for the video intercom, where you can find a specific scheme.
You can learn how to connect the wires correctly from this video:
The principle of connecting an intercom in an apartment is not much different from a private house. The only thing is that the footage of cables increases significantly, and special switching equipment for communication of all subscribers with the calling panel. Now more. Let's start traditionally with the scheme:
It is worth noting that a magnetic lock is usually installed on the front door at the entrance, with great strength retention.
Perhaps the most difficult stage is to connect the intercom to the call panel at the entrance to the front door. We start by laying the cable from the apartment to the shield located on the landing. We lead the wire from the apartment to the shield, laying it in a plastic cable channel, then carefully lower it down the access shield shaft to the first floor. Further, laying in the corrugation, we lead to the call panel or to the installation site of the switch.
Then you need to install and connect the handset. The installation site should be convenient and accessible - as in the case of a video intercom in a private house, this is the wall near the front door. We fasten it with self-tapping screws into pre-hammered dowels. Let's move on to connecting the intercom in the apartment. Having removed the front front cover, we will see the terminals. There may be two or four, depending on the selected device type. The presence of four terminals indicates the possibility of connecting another additional voice tube. The photo shows the connection procedure:
It is also possible to organize a simpler connection when the ringing device is mounted directly behind the entrance apartment door, like on a picture:
In such a scheme, there is no electric lock, and the system is used only for video communication.
At the end of the article, I would like to talk about which wires to use. As mentioned above, to connect a video intercom, use signal cables of the type KVK P 2 2x0.75 or twisted pair FTP 4x2x0.51. You can connect an audio handset with a two-wire telephone wire or twisted pair. To power the electric lock, a two-wire 2x0.75 is suitable.
We also note one important nuance with regards to electric locks, associated with access to the premises. At electromagnetic lock will stop working and the door will open automatically, while the electromechanical one will still remain closed. Remember this important detail both at the stage of operation and in the process of choosing a kit for your own conditions.
Here, according to this principle, do-it-yourself installation and connection of an intercom is carried out. As you can see, in a private house and apartment it is not difficult to do the installation yourself, the main thing is to know the rules provided and have the right tool at hand!
