The intercom often experiences various types of problems. Intercom malfunctions are usually related to the operation of the subscriber's handset. Troubleshooting sometimes requires the involvement of specialists so as not to damage the system. Individual breakdowns can be repaired independently.
Today, the presence of an intercom will not surprise anyone. He is present not only at the entrances apartment buildings, but also office buildings, providing visitor control. But sooner or later you may encounter breakdowns. It’s difficult to understand on your own what and how it is, especially if you don’t know the structure of the intercom and how it works. Let's fill the knowledge gap.
An intercom is a device for collective use, therefore, under heavy loads, some of its parts may break. In addition to the behavioral factor, there is also a weather factor. Since the device is located outdoors, it is constantly exposed to heat or cold, which can result in short circuits or other damage.
The call panel usually contains several functional buttons:
Metal is used to make the keyboard, but even this does not always cope with its task. Under the buttons there are contacts printed on printed circuit board conductor.
A metal grille is used to protect the speaker and microphone, and especially durable glass is usually used to protect the indicator.
The best strength characteristics of the intercom body, which is made of a special alloy. It is not afraid of corrosion due to temperature changes.
In addition to standard intercoms, there are models with video communication. Its call panel contains additional elements, which also have protection from weather conditions. It's about about the lens opening and infrared LED for night vision, which have a small diameter and are protected by special glass with high strength characteristics.
The outer panel is attached using inside entrance, using screws without slots. Electric wires, involved in connecting the system, are placed in a special corrugated sleeve.
After dialing the desired number the signal is transmitted to a handset located in the apartment. But to do this, he needs to go from the control unit, common to the entire entrance, to the lock button and switchboard, and only then will the treasured bell ring in the apartment.
The switch acts as an apartment number recognizer, which allows you to transfer the call specifically to the desired subscriber. If the call is answered and you decide to open the door, you need to make a response manipulation by pressing the answer button. This transmits a response signal to the control unit. The magnetic door unlocks and the entrance to the entrance opens.
With the video intercom function, the called subscriber also sees his visitor, which gives such models an advantage over conventional devices.
If we consider the reasons why the intercom in the apartment does not work, we cannot do without finding out the types and characteristics of the installed devices. Let's consider two types of devices:
A distinctive feature of digital devices is a two-wire signal transmission line. The apartment number is determined by jumpers that are located in the subscriber's handset.
Signal transmission in coordinate systems occurs through a commutator.
Another type is a video intercom. Most often it is used in private households or office buildings. An intercom of this type allows you not only to hear the visitor, but also to see him.
The most common reason why intercoms of this type do not work may be incorrect connection of the device. The call signal from the visitor to the subscriber is transmitted through 4 wires, which provide audio and video communication. Each wire has its own color and if the wire is placed incorrectly, the signal cannot be processed by the system. You can eliminate this nuisance if you carefully study the instructions for the device, or entrust its installation to professionals.
The cause of the breakdown is improper operation, non-compliance with recommendations, timely maintenance of equipment. Minor repairs intercoms are carried out frequently, since a small malfunction over time leads to dysfunction of the device.
The intercom brings convenience to life until problems arise Possible malfunctions:
You can determine why the intercom does not work experimentally. Use a multimeter to check. To eliminate any detected breakdowns, you may need a soldering iron and practical skills in repairing electrical equipment.
The first way to determine a malfunction is visual inspection. It is easy to identify by eye the detail that may have caused the system malfunction: broken or exposed wires, broken/missing buttons on the calling panel. The cost and difficulty of adjustment depends on the severity of the damage. It may be necessary to partially replace parts and install a device suitable for operation.
A multimeter will help determine problems in the wires Has the intercom stopped responding to key presses or applying the key to the reader on the door? It is recommended to check the power supply to the device. If there have been short outages in the past, it is likely that the power supply has been interrupted. Ignoring the problem led to a complete lack of electricity supply.
A frequently occurring malfunction is a non-functioning element in the tube. To correct the situation, it is necessary to inspect and repair the intercom handset.
One likely area for a break is the switch wire. The damage is easy to fix yourself. If there are no visible signal breaks, but the switch is suspected of being faulty, the check should be done by a technician.
Attention! If the intercom doesn't work, who should I call? It is recommended to contact the company that installed the device. The company's technicians repair intercom tubes.
A malfunction is possible due to incorrect switching, a complete lack of communication between the external panel on the door and the subscriber. The reason is the subscriber handset - it breaks frequently. If the circuit is coordinated, the switch checks the buses under the symbols “E” and “D”, which are responsible for units and tens, and checks each pair for subscriber handsets.
The standard resistance of devices is in the segment between 600 and 800 Ohms in one direction, and in the other there is no final value. If any tube does not meet the given resistance values, it is the cause of system failure. The repair consists of correcting the polarity and eliminating the short circuit.
To check the power supply there are the following prerequisites:
At times the signal is interrupted and the speakers produce a low sound Typically, systems use two channels of power supply with ratings of 12 and 18 V from a power supply installed to electronic devices and to the electromagnetic lock. First of all, it is recommended to pay attention to the fuses. Defective ones will need to be replaced. Replacing a unit in the event of a breakdown is entrusted to a specialist; it is difficult to do the work yourself without damaging the system.
If no external damage is found on the device, a broken cable may be to blame. The cables are checked with the same tester.
Sometimes video intercoms can also break down. This indicates a malfunction of the video camera or loss of signal. To check the serviceability, the camera is connected directly to interior panel. If everything is in order, the cause of the breakdown is the wire.
Is your intercom broken? What kind of breakdowns occur in the device tube, how to fix them? Here are the common types of breakdowns.
It happens that when a visitor presses the remote entry button, the connection with him from the apartment is lost. The conversation is interrupted, but the button does not open the door. The cause of the malfunction is a damaged wire. How to fix an intercom? You will have to remove the case and check the soldering near the speaker tube. If you find a fallen wire, you will need to solder it back into place, not forgetting the polarity.
A rarer case is a break and damage to the speaker wires. Such a breakdown cannot be determined visually; you will have to use a tester. Some models allow you to turn off the speaker volume if the apartment owners do not want to be disturbed. This function sometimes causes failure due to poor/dirty contact.
Important! Replacement of intercom elements must be carried out taking into account the polarity.
The cable condition is checked with a tester The normal call drop mode is carried out when the intercom handset is hung up without pressing the door lock opening button. A special switch is responsible for the function. Usually this is a tongue holder. To solve the problem, it is recommended to replace the part.
A number is dialed from the intercom calling panel, but the call is not made. The problem occurs if the polarity of the connection is not taken into account during installation. To correct the situation, you will need to find the wire in the intercom system switch that is responsible for connecting the external panel and the handset, and swap the negative and positive wires.
In case of such a malfunction, it is recommended to pay attention to the speaker and microphone of the handset. Perhaps they were the reason for everything. Sometimes the sound is quiet due to insufficient contact. It is necessary to check how the connector fits on the intercom handset. If it is loose, it is recommended to try tugging it while talking. Are there any glimpses of normal sound? So it’s worth establishing a connection.
Intercom repair is not so much difficult task if you know the procedure There are many reasons for intercom breakdowns in an apartment. Do-it-yourself intercom repair is sometimes difficult. You should not stroke your pride by refusing the help of specialists. If the intercom is broken, call the company that carried out the installation and provide your home address and apartment number. They may be able to detect the problem remotely. Otherwise, the experts will come and fix everything in as soon as possible. If the owner pays for the intercom, then he pays for maintenance and repairs. So why should he repair the intercom himself?

AlexeiAn intercom is the same equipment as a camera, telephone, iron or vacuum cleaner, and has its own service life, during or at the end of which all sorts of breakdowns of individual elements occur.
In this article we will analyze the repair of such fundamental parts as the electromechanical lock and handset. Less commonly, the problem occurs in the wiring or calling panels.
With the growing popularity of intercoms and their prevalence in apartment buildings, many owners often face such a problem as a broken pipe - the same one that causes people outside the house to request entry inside.
Particularly cunning craftsmen can raise the price for repairs highly if they discover that the owner of the apartment has no idea about the operating principle of this or that equipment. And if the tube is also of poor quality and is prone to frequent breakdowns, then you can completely grab your head from how much money is spent on repairs! If this problem is familiar to the reader, then it’s time to learn how to repair this element of protection with your own hands, almost free of charge.
Among typical problems the following can be distinguished:
And they occur due to failures of the intercom calling system, but there are physical malfunctions inside the handset itself. Depending on the model and manufacturer, the handset is modified with LEDs, the ability to mute the sound, change the tone, ringer volume and the ability to connect a second handset, while also having its own ordinary functions - an intercom door open button and an intercom.
If you disassemble the body of the handset, you can see an ordinary circuit: a small board, several wires, a speaker, a switch, a button, a reed switch, and everything in the middle of a huge free space. Most often, reed switches, switches, buttons and the housing itself break. The main reasons for their failure are:
Most often, the “tongues” of the case that act as a holder for the tube itself break. The repair method couldn’t be simpler: just solder the broken part back into place, and if you have good superglue, that will be enough, but not for very long. If such a “language” also includes a communication chain, then you will have to use only a soldering iron and with extreme care, so as not to cause breakdown of the rest of the system.
Another common problem with tubes is poor functioning of the door release button. They may not work the first time or even perform a reset function.
The root of the problem is always the microswitch under this button.
To begin the repair, you need to open the tube and inspect the switch. It is usually installed in two positions:
If, when you press the door open button, the bell is reset, but the door does not move, then you need to evaluate the quality of the soldering of the wires near the speaker in the handset. By soldering the wire back, you can completely get rid of this problem.
But a rarer case may also occur: broken wire in speaker coil, and, unlike the first problem, it will no longer be possible to visually determine it; you will have to use a multimeter or tester. But most common reason– contamination of contacts created to turn off the bell in order not to wake up the whole house from a late guest who has the wrong number.
One more problem - hang up the call immediately after picking up the handset. Depending on the handset model, a reed switch or a switch located under the tongue is responsible for disconnecting the circuit when the handset is returned to the base without opening the door. In this case, it is enough to simply replace the faulty switch.
Reset when dialing an apartment- a situation that occurs immediately after installing an intercom and handsets in the house. If the technician did not take into account the polarity of many wires and contacts when connecting them, which is important and is the root of the problem, then the caller simply will not be able to get through to the required apartment.
WITH modern intercoms This may not happen, because the polarity marking of the place where the base is connected to the main line is present in the same way as on the wires.
Poor audibility during a call– a malfunction in the microphone and speaker. Most intercoms have a trimming resistor on the board, which is directly related to adjusting the balance between the microphone and speaker. By remembering the initial position of the slider, tugging it from side to side and returning it to its original position, you can completely get rid of poor hearing. But it is worth noting that terrible audibility, interference and nasty sounds can be a consequence of economy, a consequence of buying a cheap intercom.
The definition of this element is simple - it is a mechanism that directly closes the intercom. There are several factors of failure, and they can exist both together and separately:
The first and most necessary step in repairing any part is diagnostics. Thanks to it, you can determine the plan, duration and cost of the work, and it must be carried out regardless of the obviousness of the ailments.
Repair and restoration work continues with the purchase of parts necessary for replacement, and then checking the condition of the cable line. You can install new parts yourself, but whether they will start is another question, the answer to which is best found in the first stages of work.
You need to install a rubber lining under the lock anchor, thanks to which no external forces will not be able to open the door, thereby deforming the anchor or fasteners.
The unevenness of the surface to which the electromechanical lock will be attached must be measured, leveled with a hammer, and holes drilled in in the right places, calculating them several times as accurately as possible to avoid distortions. Leaving the gaps for the future, you can adjust the position of the lock and the tightness of its fit to the anchor. The lock installation is complete.
If cable line It is also in poor condition and needs to be restored. It is necessary to check the joints, seal them if necessary with electrical tape or a corrugated sleeve, connect broken wires or replace them completely, if appearance unsatisfactory. If everything is done correctly, the mechanism will work instantly.
All that remains is to check the operation of the closer. If it is not suitable for working outdoors, replace it and regulate the pressure in the off-season, where the door closing process is fast in the first 2/3, and slow in the remaining third. This way you can avoid loud and unpleasant bangs in the summer, and slow, heat-dispersing closing in the winter. Repairing the lock will cost about two and a half thousand rubles, together with the handset - in most cases free of charge.

Intercom handset repair
As it turned out, repairing intercoms and taking care of them is a necessary and not so complicated procedure, ensuring the reliability of the protection for which funds were collected from the entire entrance, and even the house. If you managed to convince stingy neighbors to donate money for the purchase and installation of an intercom, then in order to avoid wasting more more nerves, we can advise you to simply take on the repairs yourself, because if you want to do it well, do it yourself. And if your neighbors are loyal to you and are faced with a breakdown, this is a chance to earn a little money that you shouldn’t miss.
