How to connect an electromagnetic lock: connection instructions

The ease of use and small size of intercom control systems have led to their widespread use. Intercoms are installed both in door frames in entrances and in doors of commercial buildings.

Owner calling devices with an electronic key reader are found in households located at a considerable distance from gate systems and other buildings on the site.

Despite the technical complexity of the intercom system, connecting an intercom to an electromagnetic lock is a trivial task if you know the installation diagram. This operation can be performed independently without the involvement of specialists.

Principle of operation

The principle of operation of the product is to activate magnetic elements as a result of applying voltage to the winding and housing through the wires and terminals of the core. As a result of these actions, a voltage of 5 W or more produces a magnetic adhesive force of 150 kg or more.

When the voltage is turned off and the lock is opened, an oscillatory circuit with alternating current is formed. The discharge process, thanks to the presence of a capacitor, occurs through the winding. This changes the polarity of the magnet element. The remainder of the current is spent on magnetization reversal.

If the capacitor fails, it becomes necessary to open the door with considerable effort. In this case, replacement of the part is necessary. The new capacitance is installed parallel to the terminals. Moreover, it must be non-polar.

What do experts recommend?

An electromagnetic lock requires a special approach to maintenance. So, experts recommend:

• Periodically check the condition of the plate. This is necessary to ensure normal adhesion to the electromagnet. The problem with EMR is that the strength of adhesion depends on the distance to the source. Geometric progression applies here, so even a few millimeters play a significant role. As soon as moisture gets on the plate, the oxidation process begins. At the same time, the hydroxide and oxide prevent the mechanism from performing its functions, which may result in a decrease in adhesion force in the future.
• Be careful when installing an EM lock on a door. As a rule, during the fastening process, self-tapping screws or other elements are used that weaken the force of the locking mechanism. This is why this parameter must be checked to avoid the plate falling off.
• Purchase or find a master key. This product is used to service the controller and encode the entry card. If you lose a key, take a spare key in the box with which you can program the rest.
• Observe safety precautions. During the installation of EMC, many people confuse the output and input terminals or leave large open parts. As a result, a short circuit and a decrease in product life are possible.

An electromagnetic lock is a reliable assistant in protecting your home, apartment, office or any other premises. The main thing is to carefully approach the issue of its selection and installation.

If you do not have the necessary knowledge and time to consider the topic, it is better to trust the professionals.

Locking mechanism

An electromagnetic lock is a fairly simple device. The main components of the mechanism are the core with winding and the housing. In most cases, the core is glued together from transformer electrical sheet steel. This material was chosen to reduce the effect of residual magnetization when opening the lock. Also, to eliminate residual stress, a special paint coating is applied. However, this does not give the full effect of eliminating accumulated stress.

In most cases, the element is made in the form of a set of small plates welded in the shape of the letter “W”. However, sometimes a solid core is used, which is much smaller in size, but has a significant drawback: such an element is capable of intensively accumulating residual stress. Therefore, in a circuit of devices of this type, a high-capacity capacitor of 200 μF is installed parallel to the core.

The winding is a coil with a huge number of turns of enamel-coated copper wire. The body of the product is often made of aluminum or stainless steel. It is possible to use plastic elements, but this design is not durable and reliable.

Additional devices for connecting to EMS

During the installation process, additional devices can be connected to the electromagnetic lock to increase its functionality and reliability.

Here are some of them:

• Intercom;
• Video intercom;
• Door closer;
• Call button;
• Code entry panel and other products.

The closer ensures smooth closing of a heavy door leaf, which reduces the wear rate of parts and helps extend service life.

If the EMZ is installed on a gate or gate, an intercom is installed along with the device.

Types of electromagnetic locks

Taking into account the possibility of using various locking mechanisms in the device, the products are conventionally divided into the following types:

• Shear;
• Retaining.

The main difference between the systems is the operating principle. Thus, electromagnetic door locks of the sliding type have a small anchor installed in the cross section. The holding anchor is triggered to break away. The advantage of sliding electromagnetic locks is the possibility of hidden installation inside the door leaf. This product does not block the opening.

Magnetic

The electrical functions of the most common type of electromechanical locks are realized through the operation of an electromagnet. They are equipped with a two-component crossbar. One part of it works as a latch, which, in the closed position, rests against the jamb and cocks the spring of the main bolt.

The electrical impulse supplied to the coils of the magnetic electromechanical lock must be short-term (fractions of a second). If current is supplied for a long time, they can overheat and fail. This point must be taken into account during installation.

When voltage is applied, the electromagnets built into the housing attract the main bolt stopper, and the door unlocks. The button mechanisms on the inside and the cylinder on the outside also operate the main bolt bolt. Models are available with and without a button lock.

Motor

The bolts of motor electromechanical locks are driven by a compact electric motor. They are usually fixed with stops in the closed or open position. This feature increases the reliability of the lock due to the fact that a closed bolt is more difficult to press.

On the other hand, the use of an electric motor does not allow you to unlock the gate instantly. Some time passes between the signal being given and the bolt position changing. Some models allow you to program a delay, which can be used to remotely control the lock, say, from the front door of a house.

Solenoid

The operating principle is based on a solenoid. The core, which acts as a crossbar, moves using inductive fields. Depending on the polarity of the coil placed in the lock body, the bolt locks or unlocks the structure on which the lock is mounted.

For stable operation, solenoid-type locking devices require a constant supply of current. Thanks to the use of low currents (12/24 Volts), they are well integrated with uninterruptible power supply systems.

In some models, the core is attached to levers that move the bolts. There are also options equipped with additional unlocking and locking mechanisms (buttons, cylinders, etc.). The use of solenoids makes it possible to make such locks compact.

What you need to know about magnetic locks

First of all, it is worth noting one important fact: magnetic locks are a full-fledged locking mechanism that limits access to the premises.
Ordinary door latches with magnets are not considered locks, so we will not disassemble them. Just as we will not consider mortise options in which locking is done with a regular key, since this option works on the principle of classical mechanisms.

Keyless opening method is provided by special key fobs.

An electromagnetic door lock is a special device consisting of a body with a winding and a metal counter plate. A powerful electromagnetic field is created in the winding, thanks to which the housing is securely attached to the bar, and it is almost impossible to open such a door with your hands.

The body with winding and the bar are the main components of the mechanism

Pros and cons of devices

First, let's look at all the advantages:

• Very high reliability . It is almost impossible to hack such a system; it is encoded in such a way that an attacker needs to go through billions of options, which even with the use of computer technology takes a lot of time. The magnetic version is ten times more difficult to hack than the regular one, so it is often used in banks and other institutions where security is very important;

It is almost impossible to open a locked door from the outside

• Long service life . The system has no moving elements or mechanisms, so it practically does not wear out during operation. The electromagnet lasts for decades, so you don’t have to worry about the reliability of the system. In many institutions you can find systems that are used very intensively every day and at the same time last for a very long time;

In commercial buildings, the lock is included in a single access system

• Ease of use - to lock the door, you do not need to insert the key into the keyhole. It will lock itself when the lock body touches the strike plate. That is, you don’t have to worry about whether you forgot to close your house or apartment, everything happens automatically. Opening the door is very simple: you need to press a button from the inside, a magnetic key is used from the outside, and some models have a remote control;

There are many unlocking options - from tags to remote opening controls

• Multiple unlocking options further enhance ease of use . A button is placed on the inside, and chips, magnetic cards, remote controls, and code systems can be used on the outside. The latest modifications allow you to control the system from a smartphone or personal computer;
• The lock can be installed on any type of door : metal, wood, plastic, etc. Moreover, installation is not difficult, which is also important. Installing an electromagnetic mechanism is much easier than a regular one, since you do not have to select a cavity for the mechanism and adjust all the elements so that the door looks neat;

Electromagnetic systems are even installed on glass doors

• No maintenance required . Maintaining the system involves periodically cleaning it from dust and dirt. No additional measures are needed;
• Electricity consumption is minimal . Some people do not want to install magnetic door locks because they think that electricity costs will increase significantly. In fact, you will hardly notice the difference. Energy consumption is very low, so your energy bills will remain the same;
• Do not depend on weather conditions and outside temperature . If there are problems with classic designs in extreme cold, the magnet does not react to such changes and works perfectly. You don't have to freeze in front of the door while warming up the mechanism. In addition, this option cannot be damaged by vandals, because it is located inside and it is impossible to damage it from the outside;

Due to their reliability, magnetic locks are ideal for external doors.

• The price of a magnetic lock is quite affordable , it doesn’t cost that little, but if you compare it with the top options of conventional locks, it will cost even less. And if you consider that its resource is much higher, then it is easy to understand that the costs are completely justified;
• The systems can be used on both single and double leaf doors . Moreover, you can only open one of the doors, which is very convenient during use.

Double door system

Advice! To further increase the security of the system and ensure that the doors close quickly, we recommend using a door closer. It will ensure stable closing of the doors.

The closer closes the door without your participation.
As for the disadvantages of magnetic systems, there is only one - dependence on the supply of electricity. If the power goes out, the doors will simply open, which is not very good. But, as mentioned above, the lock consumes very little energy, so in case of interruptions, you can install an uninterruptible power supply; it will ensure the operation of the structure until electricity appears.

The second solution to the problem is to use two types of locks. The usual option will ensure security even if the magnetic lock stops functioning.

An uninterruptible power supply is needed in case of power outages

Important! If you use magnetic door locks for interior doors with the function of opening from the inside, you still need to provide for the possibility of opening from the outside in case of unforeseen circumstances. The easiest way is to have a special remote control that will be used when necessary.

Simple and reliable design

Due to its reliability, installing an electromagnetic lock is recommended in entrances. There are no moving parts in it. The current passing through the coil winding heats it. ice does not form, metal parts do not freeze.

If the door is closed carelessly, the electromagnet is not damaged and does not lose its functionality. There are no thin or fragile parts in it.

Versatility

The scope of application of this type of locking devices is practically unlimited. You just need to select the holding force corresponding to the weight of the door and select the necessary bracket for installation.

Manufacturers present a wide selection of sizes of electromagnetic locks, allowing them to be installed both on a heavy entrance door and in small drawers of cabinets or office desks.

Easy integration with access control system

In some electromagnetic locks, the autonomous ACS controller can be hidden directly in the housing. This can almost always be done in models designed for entrance doors. The controllers are small, especially when it comes to the compact Z5-R - simple and versatile, to which you can connect an exit button, card reader or code pad.

The connection diagram for the electromagnetic lock to the ACS controller looks approximately as follows.

It is convenient to control this type of locking devices from the video intercom calling panel. An intercom kit with an electromagnetic lock can be installed on a wicket door or gate.

Advantages and disadvantages

When determining the operating features of electromechanical locking systems, it is necessary to note their convenience. You can lock the gate lock from the inside. So, the person who is outside will not open it even with a key.

Overhead frost-resistant locks

Reliability is the main difference between electromechanical locking devices. A good frost-resistant stainless steel lock lasts a long time without replacement (up to 50 years).

An intercom requires the installation of an electromechanical lock on the gate. Composite elements located in the same circuit help provide control over the area and allow the lock to be closed remotely.

When attaching the equipment, it can be placed in a vertical or horizontal position. Before you buy a locking mechanism, you need to study the rating of these devices, the cost, and the features of fastening to the door profile.

Outdoor electromechanical version

The advantages of installing a lock on the gate are obvious:

• reliability;
• long service time;
• connection to various security systems;
• equipment price;
• use in any situation.

Connection diagram with intercom
The electromechanical lock is not universal. There are some disadvantages:

• in the event of a breakdown, it takes a lot of effort to open the gate, especially if the upper and lower crossbars are additionally installed;
• a latch that protrudes from the end of the canvas can tear clothing or injure a person passing through the gate;
• it is necessary to organize a constant power supply;
• Failures may occur at high humidity and low temperature (if the lock is not frost-resistant).

The photo below shows the lock on the gate.

Electric lock for a gate - the principle of the device

The electromechanical lock is a modern system that guarantees a high level of reliability. Heavy doors will not move until the model receives a signal from a key or device located inside the house. This function was made possible by equipping the device with a working bolt, which locks the door leading to the street.

Electricity is supplied to the device by equipping it with a button; it can be located either from the inside of the gate or indoors.

A distinctive feature of the design is the presence of an erecting bolt and solenoid. If there is a need to organize additional security, you should worry about its implementation separately.

The design of an electromechanical lock is such that its operation is controlled by a locking bolt. He enters the counter part of the lock and locks the doorway. To open it, an electrical type signal is required. It will activate the spring and lever systems, make the magnet and a small electric motor work.

What kind of lighting do you prefer?

Built-in Chandelier

Most modern models open without the need for a key. An electronic signal reader allows you to open gates using magnets or cards, which require simply attaching a locking device to the element.

Parts of an intercom system

Depending on the principle of power supply, the type and number of system components, it is customary to distinguish the order, as well as the required method of installing the video intercom. There is a certain order in the location of the blocks, which makes it possible to use the equipment as comfortably as possible.

Call panel

The first step when installing an intercom with your own hands is to install the call panel. Without this block, the access system is completely meaningless. There are different types of call panels:

• panel with only a call key; it is impossible to control the lock from the panel;
• call panel and built-in key reader;
• panel with a video camera.

As a rule, the call panel is installed at a height of 1.5 meters from the ground. This arrangement of the device makes it possible for persons to use the panel freely, regardless of height. Among other things, if there is a camera on the panel, it is easier to identify the guest from it.

power unit

Unfortunately, there is no most complete answer to the question: how to connect a video intercom. The fact is that in modern systems there are 3 types of power distribution:

• connection via 1 cable, with a built-in converter in the intercom or on the internal monitor;
• power supply with an external unit, which is installed in the house;
• installation of a separate power supply to which the call panel is connected, as well as an electromagnetic or electromechanical lock.

Important! Self-installation of a video intercom in the house must be carried out strictly according to the rules specified by the device manufacturer. At the same time, it is possible to arrange different blocks of the system at your discretion. Power supplies are installed where appropriate: with or without extension cords.

However, some types of power lines have certain restrictions. For example, if a video intercom is connected via twisted pair, then the length of the route should not exceed 100 meters.

Lock

As for the system lock, it is selected based on the required functionality. As a rule, electromechanical locks are most often used in apartments. Even if the power is turned off, the lock will still remain closed. The best type of lock is one that can be opened manually with a key without power.

If you take an electromagnetic lock, it will open automatically when the power is turned off. For public institutions, such a lock is an ideal solution, which cannot be said about apartments.

Advantages and disadvantages of the device

Like any other locking mechanisms, electromagnetic locks have their pros and cons.

Advantages:

• Quiet operation;
• Long service life;
• Possibility of combination with an intercom, call button, code entry panel and other mechanisms;
• Modern appearance.

Flaws:

• Large dimensions and weight;
• High voltage requirements;
• Ease of re-entry (after a successful first hack).

An electromagnetic lock is directly dependent on electricity. Without power supply, it stops performing its assigned tasks. This feature can be counted among the advantages and disadvantages of the devices.

From a fire safety perspective, this is a plus, because when the power is turned off, the doors in complexes with large crowds of people must open.

Based on security conditions, turning off the electromagnetic locking device when there is a loss of voltage is a minus, because it simplifies the task for an attacker planning to break into an apartment or house.

That is why UPSs (uninterruptible power supplies) are often used when installing such devices.

Intercom installation stages

First of all, you need to determine in what place this or that functional part of the intercom will be located. Next, the following operations are performed:

1. the conductor is calculated with a reserve - it allows you to easily make the required connections;
2. grooves are made on the walls or ceiling, grooves are cut in wooden structures for cables;
3. if the surface allows, it is necessary to make a groove in it such a depth that the protective corrugated hose for the conductor will fit. When laying cables over metal structures, it is necessary to install a protective tube;
4. direct installation of equipment. First, the lock is inserted. When installing it in a steel door, certain difficulties may arise, which a qualified specialist will help solve;
5. installation of power supplies. As a rule, at this stage it is recommended to seek help from a specialist. However, having basic knowledge of electrical engineering, you can solve the problem on your own. When installing an intercom for an apartment, the power supply is installed in the panel - in the entrance. In a private house, a place protected from precipitation is allocated for these purposes. If the shield is overhead, it is securely fastened. Hidden, mortise panels are “hidden” in the walls, for which a niche the size of the box is made in advance.
6. combining all parts of the video intercom into a single system. For each element, the video system is switched, conductors are connected, and the equipment is installed in places prepared in advance. It is important to carry out all work carefully and carefully so that you do not have to redo the entire system again;
7. The grooves in which the cable is laid are covered, and the finishing elements are restored.

Ultimately, after the installation work, all that remains is to check the functionality of the video intercom.

Preparing for work

On average, the installation process takes from 60 to 100 minutes. The main thing is to take your time to do everything correctly and efficiently. It is more difficult to install a mortise lock, but if you know how to use an angle grinder, everything should work out.

Several installation requirements

Useful recommendations for performing work:

1. When installing an electromechanical lock, the screws are tightened tightly, otherwise the impacts when the door is slammed shut will quickly loosen them. This will cause re-installation in the future.
2. After installation, the device is usually tested. If signs of unstable operation or jamming of the lock are detected, remove it and begin installation again in accordance with all requirements.
3. If the work is done correctly, but the locking device still does not work, you should contact a professional. This is guaranteed to bring positive results.

Installation instructions and connection diagrams

When purchasing an electromagnetic lock and subsequent installation, it is worth remembering a number of features characteristic of different types of door leaves. Below we will look at the main options.

Entrance metal door

Before starting work, prepare and lay out suitable tools. You will need a tape measure, a building level, pliers, a hammer, and wire cutters. Also prepare a pencil, drill and screwdriver.

Depending on the type of box, mounting brackets may be required. It’s good if you have on hand a core, a tap and other products necessary for installing an electromagnetic lock in metal doors.

The main fastening element of the EMZ is a cylinder with a special cap that rests on the door plane from the outside.

During the installation process, you need to mark the installation location, drill a hole for the diameter of the screw, and drill a hole for the diameter of the bushing on the outside of the door.

It is important to make sure that the bushing fits into a larger diameter hole from the outside of the door and rests against the metal sheet on the other side. The holes on the bushing and the inside of the doors must line up exactly with each other.

It happens that even with correct markings difficulties arise. They are often caused by a discrepancy between the length of the sleeve and the thickness of the door leaf.

Therefore, if the sleeve is long, it will not be possible to completely hide it. Otherwise, the mounting screw may not reach the threads.

The options may be as follows:

• In the first situation, the “extra” part of the sleeve is simply cut off. To solve this problem, an ordinary grinder is used. Next, using a tap, you still need to go through the thread to remove burrs;
• In the second situation, you need to find a longer screw, because it is unlikely that you will be able to extend the sleeve.

It is advisable to place a rubber washer between the door leaf and the “iron”, which ensures reliable contact and the necessary backlash.

To avoid rotation of the mating part around the screw, it is worth drilling holes under the studs on the back.

First, the mating part is attached, after which the EMZ itself is installed. This is due to the fact that limited space is allocated for installation of the “iron”, but you can “play” with the electromagnetic lock itself.

The EMZ is attached to the canvas using a corner (can be included in the kit). To begin with, the product is attached to the frame, and then the lock itself is installed.

To secure the corner, you will need a drill, screws and a tap. If attaching the angle to the frame is not possible, drill holes in the frame so that they coincide with the holes in the EMZ. Next, fasten with screws.

Please note that after completion of the work there will be no possibility of adjustment, so you should pay close attention to the markings. Otherwise, you will have to drill additional holes.

It is worth noting that many doors are already equipped with electromagnetic locks. If the device has not yet been installed, you can do the work yourself or invite a specialist.

As a rule, drilling or preparing a niche for a hidden part does not cause problems, but you will have to tinker with the hole for the cylinder.

Plastic doors

Installation of an electromagnetic lock in plastic doors has its own characteristics. The reason for installing the mechanism is the long service life of the product.

With frequent opening and closing of doors, the electromagnetic lock hardly wears out. In addition, the device can be connected to an intercom, a reading element or a control unit, which increases the efficiency of protecting the premises and simplifies the operation process.

But there are also disadvantages. Installation of EMZ can be done in the upper or lower corner of the door. This is due to the fact that in the process of attracting the canvas, it may deform and damage the glass.

A little about intercoms

An apartment intercom is installed at the stage of building a house, and houses of earlier construction periods were not equipped with these devices, so the question of the procedure for installation and putting it into operation is another, more complex issue. It is worth noting some nuances, namely, who services the intercom and what is the general scheme for connecting subscriber handsets.

Intercom service

When connecting and installing an intercom system, the collective or association of residents draws up an agreement with the company carrying out the installation work. The contract may stipulate a subscription fee and a period of time after which the installer servicing this device must carry out repair and maintenance work. Typically, companies provide a warranty period of up to 5 years. During the warranty period, all problems must be corrected by the installer company free of charge.

Connection diagram

The connection diagram for an intercom in an apartment building can be implemented according to two principles:

• digital circuit. This type of installation is expensive, which is why it is not very common and rarely seen. Characteristic feature: it has a limit on the number of subscribers - 255. Connection is made with two-core cables. There are jumpers on the internal board that number the apartments. When a call is made, the required handset is activated thanks to a system of jumpers that close when a digital signal is applied. If the tube is changed, then when installing it yourself, you must observe the correctness and order of the wires. Otherwise, the entire system will stop working; this is the main disadvantage of a digital system - the dependence of the tubes on each other. The failure of one tube requires reconfiguration of all tubes in the entrance.
• coordinate diagram is more common than the first option, and is the most acceptable type of connecting intercoms. In addition, this type of intercom requires more expensive and complex work. The advantage is that there is no dependency between the tubes. Problems with one tube will not cause a breakdown of the entire system at the entrance. The lack of interdependence means that the wires from each tube go separately to the control unit, so such systems have many wires. Installation must also be accompanied by compliance with polarity rules. If the installation of an intercom is carried out in an apartment building with a small number of apartments per entrance, then you can install an intercom with a built-in switching device. This direct connection of the call panel and the handset does not impair the quality of the device.

How to open a lock without a key?

The electronic intercom lock is equipped with a code value that the manufacturer and installer communicate to the apartment owners. To obtain this information, you must present your registration. The PIN code consists of four digital characters, by entering which you can unlock the door lock without a key reader.

The electromagnetic lock opens with a special code

If the reader key has been lost and there are no more spare keys, the manufacturer can issue an additional key upon request.

Why is it necessary to install an intercom in a private house?

Electromechanical mechanism for a gate Selecting a lock for a gate and completing the device There are certain criteria that a lock controlled by electric current must meet.

If during the daytime the lock can be easily opened with a button from the subscriber unit or with a key from the outside, then at night additional bolts are installed that completely block the possibility of opening the lock. Additional security measures.

Connecting wires to the video intercom is carried out in accordance with the connection diagram.

They provide significant gasket length; digital devices - use twisted pair cables for transmission. Installing mortise locks is quite a complex matter, requiring certain skills and experience with tools, so it is better to entrust this procedure to specialists.

Types of electronic locks

The negative wire of the power supply can be connected directly to the lock, and its positive wire is connected through the relay contacts. After this delay time has expired, the electromagnetic relay is activated again and the lock goes into the closed state.

Wireless 3G CCTV cameras operate on the same principle as regular video calls, so you must always be within the coverage area. This type of lock has the following advantages: Low price; Ease of installation; Can be installed on most types of doors.

Why is it necessary to install an intercom in a private house?

The final stage is sealing. This type of lock has the following advantages: Low price; Ease of installation; Can be installed on most types of doors. It should be positioned so that the panel being pulled is on the moving side of the door, and the lock is on the fixed side. The design of an electromechanical lock is similar to a conventional door lock, which can be mortise or overhead.

Twisted pair cables, used in computer networks, can be used as low-current signal wires. The specificity of this type of lock is that it moves the bolt that holds the door in the closed position. They do not fail in any frost or rainy season. In addition to its main task, easy identification of the visitor during the day and night, it takes a photo at the time of the call, is capable of organizing two-way audio communication, and performing many more actions

Also pay attention to the operating temperature range of electronic equipment that will be placed outdoors. Connecting an electromechanical lock

Types of intercom connections

Coordinate matrix. Apartment intercom devices are connected to the main unit each with their own cable. With 10 subscribers there will be 10 wires, with 20 - 20, etc. This type of connection is the most economical, but is not designed for more than 30 subscribers.

Digital intercoms have a higher price than coordinate matrix ones. Intercom units, regardless of quantity, are connected using two cables. But such schemes often fail.

Wireless intercoms belong to the elite category. They do not require an additional cable, but use existing ones. For example, telephone or Internet, or IP. Communication takes place via an Internet connection, including wi-fi. Such intercoms are more expensive, but they are more technologically advanced. They send a signal to TV, smartphone, tablet, and you can open the lock from mobile devices. It is possible to connect to a video camera and display a color image on the screen.

How to connect a phone to an intercom

Despite the great capabilities of IP video intercoms, their primary task is to control the actuators of entrance doors and communicate with visitors. And most often, users want to customize some innovations specifically for these purposes. Therefore, one of the most popular questions on the topic is how to open an intercom using a telephone. This is especially true for large country houses or for people with disabilities.

In order for all this to be technically possible, it is necessary that the intercom equipment supports a connection to the network: either the entire system must be digital, or one network element (usually a monitor) is interfaced with the analog system, which will forward to the smartphone. Integration of a digital system into an analog one is possible thanks to special adapters - more on this below.

Direct connection of the IP intercom to the phone occurs through a mobile application from equipment developers. The primary connection is carried out in different ways:

• via the intercom IP address;
• via a Wi-Fi network provided by the intercom;
• via a QR code with a link to the application, etc.

The application interface, of course, is different for each manufacturer, but, for the most part, it is simple and understandable. As a rule, cameras (one or several) and all connected devices, buttons for answering calls and opening the door, setting up notifications, etc. are displayed there. This allows you to link the intercom to a smartphone.

By the way, IP video intercom software can be more multifunctional, so owners of digital intercom networks often do not buy separate monitors, but immediately transfer all control to a tablet or smartphone.
