Where are intercoms repaired? Installation of intercoms by bank transfer, repair of intercoms by bank transfer

The intercom often has various kinds of problems. Intercom malfunctions are usually associated with the operation of the subscriber's handset. Troubleshooting sometimes requires the involvement of wizards so as not to damage the system. Separate breakdowns can be repaired independently.

How the intercom handset works: device

Today, the presence of an intercom will not surprise anyone. It is present not only at the entrances apartment buildings, but also office buildings, providing visit control. But sooner or later, you can face its breakdowns. It is difficult to understand on your own what and how difficult, especially if you do not know the device of the intercom and how it works. Let's fill the knowledge gap.

The intercom is a device for collective use, therefore, when experiencing heavy loads, some of its parts may break. In addition to the behavioral factor, there is also the weather factor. Since the device is located outdoors, it is constantly exposed to heat or cold, as a result of which short circuits or other breakdowns may occur.

The call panel usually has several function buttons:

• Keyboard;
• Button for calling a subscriber;
• Speaker and microphone for voice communication with it;
• An indicator that displays the apartment number of the called subscriber;
• Electronic key reader.

Metal is used to make the keyboard, but even it does not always cope with its task. Under the buttons are contacts printed on the printed circuit board of the conductor.

Used to protect the speaker and microphone metal grate, and for the safety of the indicator, as a rule, extra strong glass is used.

Most strength characteristics at the body of the intercom, 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 are also protected from weather conditions. We are talking about a lens hole and an infrared LED for night vision, which have a small diameter and are protected by a special glass with high strength characteristics.

The outer panel is fastened with inside entrance, using screws without a slot. Electric wires, involved in connecting the system, are placed in a special corrugated sleeve.

After dialing the desired number, the signal is transmitted to the handset located in the apartment. But for this, he needs to go from the control unit, common to the entire entrance, to the lock button and switch, and only then will the treasured bell ring in the apartment.

The switch performs the role of an apartment number recognizer, which allows you to transfer the call purposefully to the right subscriber. If the call was answered and you decided 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 is unlocked 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.

Varieties of subscriber call devices

If we consider the reasons why the intercom does not work in the apartment, we cannot do without finding out the types and characteristics of the installed devices. Consider two types of devices:

• the first type includes digital devices;
• to the second type of coordinate devices.

hallmark digital devices is a two-wire signal transmission line. The apartment number is determined by means of jumpers, which are located in the subscriber's handset.

Signal transmission in coordinate systems occurs through a switch.

Another type is a video intercom. Most often it is used in private households or office buildings. This type of intercom allows not only to hear the visitor, but also to see him.

Most common cause Why intercoms of this type do not work may be an incorrect connection of the device. The call signal from the visitor to the subscriber is transmitted over 4 wires, which provide audio and video communication. Each wire has its own color and if the wire is incorrectly located, the signal cannot be processed by the system. You can eliminate this trouble if you carefully study the instructions for the device, or entrust its installation to professionals.

Possible breakdowns, causes

The cause of the breakdown is improper operation, non-compliance with recommendations, timely maintenance of equipment. Minor repairs Intercoms are often carried out, since a small malfunction over time leads to dysfunction of the device.

Intercom brings convenience to life until problems arise

Why is the intercom not working?

Possible malfunctions:

• poor contact and power supply of the device;
• controller malfunction;
• worn keys;
• faulty power supply.

You can determine why the intercom does not work by experience. Use a multimeter to check. To eliminate the detected breakdowns, you may need a soldering iron and practical skills in repairing electrical equipment.

How to troubleshoot

The first way to determine the malfunction is a visual inspection. It is easy to determine by eye the detail that may have caused the system to malfunction: broken or bare wires, broken / missing buttons on the call panel. The cost and complexity of the adjustment depends on the severity of the damage. It may be necessary to partially change parts, install a device suitable for operation.

A multimeter will help you identify problems in the wires

The intercom stopped responding to pressing the keys, 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 interruptions in service in the past, it is likely that the power supply was interrupted. Ignoring the problem led to a complete lack of electricity supply.

A frequently occurring malfunction is a non-working element in the tube. To correct the situation, it is required to inspect and repair the intercom tube.

One of the likely sections of the break is the switch wire. The damage is easy to fix on your own. If there are no visible signal breaks, but the switch is suspected of a malfunction, the wizard should do the check.

Attention! If the intercom does not work, where to call? It is recommended that you contact the company that installed the device. The company's masters repair intercom tubes.

A malfunction is possible due to incorrect switching, complete lack of communication between the external panel on the door and the subscriber. The reason in the handset is frequent breakdown. If the scheme is coordinate, the switches check the tires under the symbols "E" and "D", which are responsible for units and tens, check each pair for subscriber tubes.

The standard resistance of devices is in the segment between 600 and 800 ohms in one direction, and there is no final value in the other. If any tube does not meet the given resistance values, it is the cause of the system failure. Repair consists in correcting the polarity, eliminating the short circuit.

To check the power supply, there are the following prerequisites:

• the call panel gives a quiet signal sound;
• tone stopped working
• poor operation of the electromagnetic lock.

At times, the signal is interrupted and the speakers emit a soft 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. Faulty ones will need to be replaced. Replacing the unit in the event of a breakdown is trusted to the master; it is difficult to do the work on your own without damaging the system.

If there is no external damage to the device, a broken cable may be the culprit. Cables are checked by the same tester.

Sometimes video intercoms can also break. This indicates a malfunction of the camcorder or loss of signal. To check the serviceability, the camera is connected directly to inner panel. If everything is in order, the cause of the breakdown is the wire.

Handset malfunctions

Broken intercom? What breakdowns are found in the tube of the device, how to fix them? Here are the common types of breakdowns.

When you press the button - the doors open, the connection is lost

It happens that when the visitor's remote entry button is pressed, 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 intercom? We'll have to remove the case, check the soldering near the speaker tube. If a broken wire is found, it will need to be soldered back into place, not forgetting the polarity.

A rarer case is breakage and damage to the speaker wires. Visually, such a breakdown cannot be determined, you will have to use a tester. Some models allow you to turn off the volume of the speaker if the owners of the apartment do not want to be disturbed. This function sometimes causes failure due to poor/dirty contact.

Important! Replacement of intercom elements must take into account the polarity.

The condition of the cable is checked with a tester

Lifting the handset is accompanied by a call rejection

The regular call drop mode is carried out when the intercom handset is placed 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.

Subscriber is not dialed

A number is dialed from the entry panel of the intercom, but the call is not made. The problem occurs if the installation does not take into account the polarity of the connection. To remedy 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, swap the negative and positive wires.

Speakers may not sound properly when talking

In case of such a malfunction, it is recommended to pay attention to the speaker and microphone of the handset. Perhaps they were the cause of everything. Sometimes the sound is quiet due to insufficient contact. It is necessary to check how the connector sits on the intercom handset. If it dangles, it is recommended to try to pull it during a conversation. Are there glimpses of normal sound? So it's worth getting connected.

Intercom repair is not so 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. Do not flatter your pride by refusing the help of specialists. If the intercom is broken, call the company that carried out the installation, provide your home address, apartment number. Maybe they can troubleshoot remotely. Otherwise, the masters will come, fixing 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?

Repair Market

As soon as the first large batches of video intercoms appeared in Russia, these were and are produced by Commax, we immediately began to repair them. They rarely broke, so there were only two in all of Moscow service centers one of them is ours. Then another strong Korean company Kocom and several Russian manufacturers appeared. Unfortunately almost all Russian manufacturers how abruptly they appeared, so abruptly they disappeared, however, for a long time, due to a small variety, repair work did not even require knowledge of electronics - to put an inexperienced person on simple repairs, explaining to him the typical malfunctions of a particular monitor - which many companies used, however, our company from the very beginning of its activity had a staff of qualified electronics specialists.

Over the past 20 years, the main manufacturers of video intercoms that are used in Russia have already become more than 50, and the number of models that they produce is more than 450. Of course, it is becoming increasingly difficult to repair video intercoms with such a variety of models. In this regard, we are especially pleased that we were not just repairers of video intercoms from the very beginning, but, first of all, electronics engineers.

Why to us?

Why is it worth contacting us with the question of video intercom repair?

As a result of the above, we carry out repairs of video intercoms both directly and as a contractor of several Moscow trading houses and installation organizations, which, however, the client does not even assume. Turning to us directly is beneficial both for the client and for us. In addition, if you give the video intercom for repair, then most likely it will end up in our workshop anyway.

List of standard intercom malfunctions/breakdowns:

	Door won't open with button
	Intercom "cracks", fonit
	Degraded image
	The intercom works, but the image is missing
	The call is audible from the outside, not inside
	Fonit calling panel
	The lock does not magnetize
	Keys don't work
	Intercom does not respond to anything

Systems for monitoring and managing the admission of people to residential buildings have been popular with the public for a relatively long time. During this time, many apartment owners at least once, but faced the problems of failures of this equipment when opening the door.

Some models, including our Digital KL-2, are equipped with a speaker switch that allows you to turn off the sound signal when you call. This can be useful if you don't want to be disturbed by a late guest with the wrong number, or if you wake up a small child who has fallen asleep during the day.

So, worn or dirty contacts of the button of this switch can also affect the reset of the connection instead of opening the door, and be the cause of this breakdown.

When you pick up the handset, the call is dropped

In normal mode, the call is dropped when we put the handset on the base without pressing the button to open the door lock. Accordingly, the switch is responsible for resetting (turning off the circuit): either a reed switch or one located under the tongue holder. It all depends on the model of the tube.

Most reliable way The solution to this breakdown is to replace the failed switch.

When dialing a subscriber's number, it is immediately reset

The indicated reason may appear immediately after installing the intercom handset in the apartment, if the polarity is reversed when connecting the wires.

Often, an ordinary telephone “noodle” acts as a main wire leading into an apartment, in which both ends do not differ from each other in any way.

In the place where the base is connected to the trunk, there is usually a plus and minus marking, but it is better to mark the wire yourself.

If the polarity is not observed, then immediately after dialing the number, instead of the call sound of the subscriber, a reset will occur. Accordingly, none of the guests, due to a breakdown in the intercom, will not be able to sound a call signal on your handset.

Poor hearing when talking

Here you should pay attention to the speaker and microphone located in the intercom handset. Perhaps they are the cause of poor hearing.

Inside the tube printed circuit board there may be a trimming resistor (it is absent in the Digital KL-2 model), which is directly related to adjusting the balance of the microphone and speaker. Just do not immediately use it to configure. Better remember the initial position of the slider, and then scroll it back and forth a couple of times. After this operation, return it to its initial state.

This will restore reliable contact on the resistor and, possibly, eliminate poor hearing on the tube.

Radio amateurs can also replace the capacitors located on the board next to the trimmer.

So we sorted out all the main malfunctions of the intercom handset for opening the door, which can be fixed on your own.

If you have a handset from an old and unnecessary phone with an ordinary battery, then in five minutes you can assemble an intercom or intercom with your own hands.

The owner of the All about everything video clearly shows this process in his video.
