Electronic lock for an iron door. Electric door locks. Contact key controllers

In pursuit of door security and quality, electronic locks have recently entered the market. Such devices guarantee safety to any room. The electronic lock on the front door has many advantages over its predecessors and has already gained the trust of many homes in the country.

Electromagnetic Electromechanical Combined
Biometric Invisible

According to the principle of operation of the mechanism, electronic locking structures are classified as follows:

• electromagnetic;
• electromechanical;
• combined;
• biometric;
• invisible.

Electromagnetic mechanisms are usually used in facilities where there is a lot of traffic, or it is necessary to provide for the possibility of opening the door in the event of an emergency power outage. They can be installed in buildings without electricity. They are usually used on the doors of emergency entrances, warehouses and other similar premises.

Electromechanical ones are installed on gates and entrances. This type of lock can be opened in several ways: using a key, an electric drive, or using a secret code.

Combined systems are considered the most common. These devices are opened using electronic keys or using a special card. Mechanisms of this type are the safest and most reliable.

Biometric locking devices are high-tech mechanisms that work by reading information from your hands and fingers. Such devices are installed in places that require a high degree of protection. They are convenient due to their practicality, because when using them you do not need keys and other additional items that tend to get lost.

One of the most reliable types of locking mechanisms is invisible. To determine where it is, you need a special device. Therefore, it is impossible to open the door with such a lock. The mechanism is controlled remotely.

Operating principle of electronic locks

Depending on the type of mechanism, each design has its own operating system:

The electronic magnetic mechanism operates using a powerful electromagnet. It attracts a metal plate that is attached to the door. When the flap is closed, an electric current passes to the magnet, which creates a strong magnetic field. This field holds the metal plate on the door as long as there is electricity. To open the door, you need to press a button. It turns off the current supply, then the magnetic field disappears and moves away from the metal doors.

According to their design, there are electromagnetic doors that open by detachment and by sliding. Magnets are attached to the canvas in an overhead or mortise manner. Most often they use overhead mechanisms that work by tearing off. They last longer and work, regardless of climatic conditions.

The electromechanical lock for the front door design operates using a bolt, which moves as a result of applying voltage to the solenoid. When the door is closed, the main bolt moves and compresses the spring. At the same time, the bolt hits the locking part, and the door becomes locked. When the door opens, voltage is transmitted to the solenoid, which removes the latch holding the bolt to the spring. This type of device can also be opened using a key.

Combined locking structures combine several types of mechanisms. Their operating principle is based on which devices have been selected for use. It is impossible to open such a structure without knowing how all the previous latches on the door open.

The principle of operation of a biometric lock is that it scans a fingerprint or handprint. Afterwards, the scanned fingerprint is compared with a sample previously stored in memory. If everything is correct, then the door opens successfully.

Invisible locking devices operate on the basis of an electric motor and gearbox, which regulate the opening and closing of the bolt. They are at a door in a place unknown to others. To open the doors, you must use the remote control from this device. It works at a distance of 1 to 10 meters.

Advantages and disadvantages

Let's look at the main advantages of electronic locks:

• Reliability is the main advantage of such devices. These mechanisms are difficult for attackers to open. Such devices do not require additional protection, because the mechanism that works in the lock is already a guarantee of security.
• The absence of moving parts in electromechanical, biometric and invisible designs contributes to durability of use.
• Practicality and convenience. Some electronic locks can be opened from a distance or without using any objects. This allows you to avoid losing your keys or having them go missing at the most inopportune moment.
• Economical. Electronic door locking mechanisms consume a minimal amount of electricity, thereby combining ergonomics and reliability.
• Electromagnetic locks are not affected by weather conditions, so they can be used in places that are exposed to nature. Thanks to this property, you don’t have to worry that the devices will fail due to rain or frost.
• Electromechanical structures do not require a constant supply of electricity. This makes them very economical. To operate such devices, a battery is sufficient, which is changed once a year.
• Biometric devices have a number of advantages. Indeed, in addition to the main function, they have a backlight, a notification function that the door is not closed, and their own alarm system that notifies of an attempted break-in.

Flaws:

• The main disadvantage of most electronic locks is their dependence on electricity consumption. If in the case of electromechanical devices you can install a battery for power, then in other door locks difficulties will arise when there is no electricity.
• Installation electronic door mechanisms are a very expensive pleasure. It will be difficult for a non-specialist to complete the installation on their own.
• All electric locks, in addition to electromagnetic ones, are affected by water and frost. To protect the device, you need to place a canopy or canopy over it. In the case where the doors are located indoors, this drawback will not become a hindrance.
• Installed The biometric mechanism may not work if there are cuts on the hand or finger or they are dirty. To prevent such situations, it is necessary to store several scan options in the device’s memory.

Recommendations from experts on the operation of electronic locks

In order for the electronic locking mechanism to work for a long time and without interruption, you should adhere to the following recommendations:

• you need to protect your electromechanical or biometric lock from water and condensation;
• Electromechanical devices should not be used in offices, as they wear out quickly;
• When choosing an electronic lock for entrance doors, you should take care of the possibility of connecting it to an autonomous power source. This will protect you from unforeseen circumstances.

Installation of an electronic lock

To install an electric lock on a door with your own hands, you need to go through two steps.

The first stage is to choose a lock that is suitable for the entrance doors. In this case, you need to take into account what the door is made of, where it is located, and what degree of protection is necessary in this case.

Experts say that you need to consider the door leaf and the locking mechanism together. After all, everything should fit together. The front door will be different from the design installed in a country house, therefore the electric lock will be different in each case, this must be taken into account. The second point to installing a door lock is preparing the necessary tools.

The designs of electric locks themselves have two types of installation: overhead and mortise. The first type is installed on the door leaf without damaging it. Mortise ones are placed inside the canvas.

Electronic lock

To install an overhead electronic lock on your front door yourself, you need to:

• Prepare a marker, tape measure, pencil, electric drill and screwdriver.
• Make a marking where the electromagnetic lock is supposed to be installed on the door;
• In the marked places, using an electric drill, you need to make holes for fastening. They must match the diameter of the bolts for fastening.
• Next, you need to drill a through hole through which the device body and the reading mechanism will be connected.
• The mechanism body is installed and secured in the marked place.
• Next, the locking plate is installed.
• The reading device is installed.

Mortise electronic lock

This process is a little more complicated because it is necessary to drill niches for the frame and strips in the door leaf and jamb. Let's look at the installation process step by step:

• For ease of operation, you need to remove the door from its hinges.
• Mark the size of the niche that needs to be cut. It should be slightly larger than the lock body;
• Next, the niche is cut out.
• When the hole is ready, it is cleaned and irregularities are removed.
• The last step is to directly install the electronic lock into the niche and secure it with fastening materials.

How to connect an electric lock

After installing the lock on the front door is completed, it needs to be connected. In most cases, the device comes with instructions and a wiring diagram for the electric lock, which will help you connect it quickly and without errors.

But it is better to install an electric lock by professionals; this guarantees not only time, but also the functional reliability of the mechanism, and eliminates breakdowns that may occur due to incorrect connection.

An electric lock on the front door is a reliable protector of the room. The benefits of these devices make our lives much easier.

The article will tell you about the designs of electronic locks available on the market, from it you will learn the principle of operation of locking mechanisms, the types of electronic lock control systems used. Reading will help you make the right choice of electronic lock.

The use of electromagnets and servos has made it possible to change the understanding of the design of locks. A new generation of locking mechanisms uses a commanded electrical impulse (usually 12 VDC) to move the bolt or create clamping force. This made it possible to use electromechanical locks in the locking part of the door, which differ in design from classic mechanical locks, which generally increases the security of the home from entry by unauthorized persons.

With the help of microprocessor control systems associated with electromagnetic or electromechanical locks, access to the premises of a certain circle of people is easily organized, remote control of the door locking mechanism is performed or the door is opened without a classic key. All this is almost impossible to implement using standard mechanical locks.

Due to the simplicity of their design, electromagnetic and electromechanical locks are able to safely withstand tens of thousands of opening and closing cycles, which is beyond the capabilities of conventional mechanical locks.

Based on the principle of organization of the locking mechanism, modern electromechanical locks can be divided into the following main groups:

1. Electric deadbolt locks.
2. Invisible locks.
3. Electric motor locks.
4. Electric latches.
5. Electromechanical locks.

Based on the control systems installed in them, locks can be divided into four types.

Radio controller

These systems can recognize both specialized key fobs and operate on standard frequencies of Wi-Fi or Bluetooth networks. In the latter option, a standard tablet or smartphone can be used as a “key”.

Code keyboards

The simplest and most common technical solution for electronic lock control systems. To activate the lock mechanism, you only need to enter a specific code, so there is no need to additionally purchase different types of keys.

The main “disease” of this control system is the erroneous operation or failure of the digital remote control keys, which is due to the peculiarities of its design. Over time, the contact plates oxidize and may not close the contact or distort the supplied signal, which leads to erroneous operation of the buttons. Therefore, all locks with keypads require regular maintenance.

Contact key controllers

One of the most common solutions on the electronic lock market. The lock allows you to store a certain number of contact keys in the memory, made in the form of a key fob or a plastic card with a magnetic strip. The system has a high degree of reliability.

Proximity key controllers

This system allows you to work with special radio-magnetic cards, which are activated remotely (at a distance of 10-15 cm from the reading device).

Electronic lock combining control using a code, contact key and radio key fob

Let us consider in detail all types of electronic locks, their advantages and disadvantages.

Electromagnetic locks

Electromagnetic locks are less similar to classic mechanical locks than other electronic locks. They consist of three main parts:

1. Electromagnet plates.
2. Reciprocal metal plate.
3. Control systems.

These electronic locks are widely used as a locking mechanism on metal entrance doors. The microprocessor system that controls them operates both in intercom mode (reads and processes information from the keyboard and remote handsets) and analyzes information from contact keys.

Advantages

Thanks to the high reliability of the electromagnetic lock in combination with the significant force of attraction of the plate to the lock (50-500 kg), such a door guarantees a sufficient degree of protection of the premises from third-party penetration. The installed electromagnets and the outdoor part of the electronic lock control system are protected from moisture, which increases their reliability.

Electromagnetic lock for 230 kg

After being disconnected from the power supply, electromagnetic locks can operate for a short time on a battery connected to the control system. After the battery is discharged, the electromagnetic lock will automatically open.

Flaws

The disadvantage of this system is the poor noise immunity of the communication lines of the control system with feedback tubes installed in each apartment, which can lead to failure of the entire system during a severe thunderstorm.

Independent repair and installation of this system is rarely done, since it involves performing a large amount of installation work with subsequent adjustment of the control system.

Electric deadbolt locks

This type of lock is similar in appearance to a classic mechanical deadbolt lock. It can be equipped with various control systems, which ensures its versatility.

The system includes an electromagnetic bolt wire, which can be used to both open and close the door. Some models, thanks to built-in spring return mechanisms, ensure automatic closing or opening of the lock in the event of a power failure.

Advantages

The electromagnetic mechanisms installed in these locks are highly reliable, significantly exceeding mechanical locks of similar class. A number of models are equipped with a door condition monitoring system, which eliminates spontaneous operation of the locking mechanism when it is open.

All models are easy to install and configure; installation and maintenance work does not require special knowledge, which has led to their high popularity.

Flaws

Inability to open the door if there is no power to the lock.

Since this lock consists of an electromagnet, return springs and an electronic control system, its repair is limited to checking the functionality of the magnet and the condition of the springs, and maintenance is limited to lubricating moving parts and replacing bushings and return springs. When the lock is equipped with a control system that works with contactless keys or with radio control, they can be used as “invisible locks”.

Invisible locks

This type of locks is specially designed for hidden installation. Both electronic deadbolt locks and compact latch locks can be used as these locks. Invisible locks can be installed in various parts of the door leaf, or built into standard mechanical locks, which significantly increases their resistance to burglary.

The lock comes complete with a control system that reads signals sent via a radio channel. Radio networks can be used as a signal source for opening and closing an electronic lock.

The lock is powered from a separate power supply (usually 12 or 5 VDC). Auxiliary battery power supplies are used to independently power the lock during a power outage. When purchasing an invisible lock, you need to pay attention to the condition of the locking tab; the best option is when the tab is initially retracted.

Important: if there is no power for a long time, the self-closing lock will not be able to be opened.

Advantages

This lock is quite simple in design and contains a minimum number of working components, making it easy to set up and, if necessary, repair.

Flaws

Cannot be used as a separate locking mechanism due to the simplicity of the design.

Electric motor locks

This type of locks is no different in its capabilities from electric deadbolt locks. Its main difference is the use of a compact electric motor to move the locking mechanism.

A feature of some locks that use an electric motor as a driving element is their integration into a single control unit. Control units can process information both from the keypad and from various types of key fobs.

These electric motor locks are installed directly on classic mechanical locks with a cylindrical cylinder. With their help, you can easily and with minimal time and effort convert a classic mechanical lock by replacing the conventional lock cylinder with an electric motor one.

Example of an electric motorized invisible lock

Advantages

Low power consumption and, as a result, the possibility of long-term operation when powered by classic AA batteries.

Disadvantages also include the complexity of the mechanism, which requires regular maintenance, including maintenance of the locking mechanism, controlled by a mechanical and electrical drive.

Operating principle of an electromechanical lock

Ready-made solutions based on various types of electronic locks:

Thanks to a simple combination of electric locks with various types of control systems, it is possible to create an access system of any complexity, providing a high level of protection against burglary.

The ability to open remotely or process wireless radio signals of various frequencies by the control system and simplicity of design are the main advantages of electronic locks over mechanical ones. The simplicity of the design of actuators and the versatility of control systems increase the reliability of systems built on their basis.

A high-quality and reliable locking mechanism for the front door is one of the most important elements for ensuring the security of a private home or apartment. Electronic door locks have recently become widespread and have gained popularity among consumers. Such a mechanism can be located in any part of the perimeter of the door block, which allows you to hide its location from intruders. In addition, the electronic lock is not equipped with a keyhole.

As a rule, such locking mechanisms are opened using a plastic card, electronic key fobs or the personal code of the home owners. In addition, there are models of electronic locks that can only be opened using the owner’s fingerprint.

Features, advantages, prospects

The main advantages of electronic door locks are ease of use and effectiveness in protecting your home from burglars. The greatest reliability can be achieved in a combination of such a locking mechanism and a high-quality metal entrance door. There are two types of electronic locks: electromechanical and electric, equipped with a magnetic carrier.

In addition to private country houses and city apartments, such locks are used on entrance doors at checkpoints in office buildings or institutions. In addition, they can be used effectively in warehouses. Such locks come in mortise and overhead locks.

It should be especially emphasized that it is almost impossible to break into such locking mechanisms. Even if such a lock is damaged or broken, then it will not be possible to open the door itself. The lock will lock and stop functioning. It will be possible to open such a failed mechanism only by using special professional tools. It would be appropriate to say that this feature of electronic door locks is both an advantage and a disadvantage. On the one hand, they cannot be opened by intruders; on the other hand, if the lock breaks down, the owner of the premises will not be able to enter or exit without the help of specialists from special services for opening doors.

Another advantage of electronic locks is that some models are equipped with so-called artificial intelligence. This refers to the presence in the design of the mechanism of time sensors, which make it possible to record when the premises were visited. In addition, such locks can be programmed to perform various additional functions.

Electronic locks have a long service life and are considered more reliable compared to other types of locking mechanisms. Despite a significant number of advantages, such mechanisms also have a number of disadvantages:

• Insufficient resistance of electronic microcircuits inside the structure to mechanical damage;
• The likelihood of electronics malfunctioning due to changes in atmospheric pressure;
• The presence in some models of the function of opening and closing using a password. This code may be forgotten by the owner of the premises or seen by a potential attacker.

The last drawback can be mitigated by contacting specialists who are able to program an electronic lock to work with a new secret combination.

Types of electronic locks

Today, the range of electronic locks is represented by several main types. An electronic locking mechanism, opened using a plastic card, is typically used on doors in hotels, cottages and office buildings. This type of lock is quite reliable and protects premises from unauthorized access.

The electromechanical door lock can be opened in three ways. The first of these involves the use of keys and an electric drive mechanism. Such locks can be opened in the immediate vicinity of the door and at some distance. In addition, such locking mechanisms are opened using a secret combination. This is a so-called digital lock. Electromechanical locks are often used on gates or placed on entrance doors.

Combined locking mechanisms are devices equipped with an electronic key. This type of lock is the most widespread today. Such devices are opened with a pair of keys or plastic cards and are the most reliable type of electronic locking systems. A special feature of combined electronic locks is that they cannot be opened with just one of the keys. Only with the consistent use of all opening devices provided by the design of the system will it be possible to get inside the room or building.

The biometric electric lock on the front door can only be opened using a fingerprint, for which the locking mechanism is programmed. Such a system operates using a sensor program for reading information. The undoubted advantage of such locks is that the owner of the premises or building does not need to remember a secret combination or carry plastic cards and keys with him.

Invisible electronic locks are hidden from prying eyes and it is simply impossible to find them on the door leaf without the use of special equipment. The process of opening and closing the locking mechanism is carried out by rotating the bolt, which is driven by a gearbox and an electric motor. This lock design increases the safety and reliability of the front door and facilitates its effective locking. The basis of invisible locking systems is a powerful bolt, the location of which an attacker simply cannot know. The design of such a lock does not have keyholes or a user interface. It unlocks at a distance of 1 to 10 meters.

It would be helpful to say that you can install an electric lock on the front door yourself. First of all, this applies to overhead models, because in this case there is no need to embed the mechanism into the door. The advantages of electronic locks have already been appreciated by owners of offices, warehouses, government agencies and manufacturing organizations. In addition, the great popularity of such mechanisms can be observed among the owners of private houses and city apartments.

Today, there are many models of electronic locks in various price categories on the market. The cost of such products depends on a number of factors. For example, the price of an electronic lock is influenced by the device’s ability to synchronize with a mobile phone, the presence or absence of a display and keyboard, remote opening range, and the number of deadbolts. In addition, the cost of electronic locks depends on the connection to a common security system, the presence of an audible alarm about low battery, the reliability of the lock and resistance to attempts to disable the device.

Operating principle

Electronic locks close the door using a bolt. To open the locking mechanism with a plastic card, the sensor must read information from it upon contact. Such cards are included with electronic locks and cannot be counterfeited. In addition, using a plastic card from another similar locking device will not work - they are not compatible.

When unlocking the electronic lock, you must press the door handle. At this moment, the spring compresses and puts pressure on the bolt, causing the door to open. When the door leaf is closed, the reverse process occurs, that is, the spring is weakened and the bolt, when released, is fixed between the leaf and the door frame. The crossbar is controlled using electronic magnets or solenoids.

It should be emphasized that locks using solenoid control respond faster to a signal, so it is advisable to install them on entrance doors with several opening phases. When working with such systems, there is no need for keys. As a rule, they are equipped with a reading sensor and a plastic card.

It should be noted that when using electronic door locks, the opening speed increases significantly compared to traditional mechanical locks with keys. In addition, the service life of a high-quality electronic locking system is practically unlimited. This is due to the lesser influence of corrosion and the rare occurrence of failure. The structural elements of such locks almost never jam.

There are several sources of the signal that the electronic door lock receives as a command to move the bolt. So, it could be a plastic magnetic card, a contact memory sensor, a barcode or a biometric sensor. In addition, such a signal comes from the code keypad located on the lock itself, key fob or remote control. Also noteworthy are fluorescent combinatorial molecular sensors. The latter type of sensors appeared relatively recently and is currently not widely used in household use.

Is it safe to use this lock?

It should be noted that most models of electronic door locks operate from a 220V electrical network, but the current strength may vary. This nuance must be taken into account when purchasing a power supply. Security experts recommend adding at least one more locking mechanism to the electronic door lock to increase reliability. In this case, the operating principle and design of the second and any other lock must differ from similar characteristics of the main device.

It is important to emphasize that the electronic combination lock for the front door is equipped with a rechargeable battery, which can ensure the device operates for some time even in the absence of a constant electrical supply. When the battery is low, a notification will be sent to the owner's mobile phone via SMS or a sound signal will sound.

Do not forget that even such reliable and progressive locking systems require periodic maintenance. This will extend the life of the electronic lock, increase the quality characteristics of its operation and, accordingly, protect the property of the owner of the premises. It would be appropriate to say that the use of electronic locks on entrance doors often confuses intruders who are accustomed to seeing traditional mechanical products in front of them. This can buy you valuable time and prevent break-ins and theft. In conclusion, it is worth noting that installing a high-quality electric lock on the front door is a progressive solution. A door with such a locking system will become a reliable barrier in the way of intruders.

The lock on the front door should remain reliable and durable. At the same time, a high degree of ease of use is desirable. Classic mechanical designs have several difficulties with this point, since opening requires a key and the direct presence of a person next to the keyhole. An alternative would be an electric door lock, which can be built into centralized access control systems and controlled remotely, which is convenient for apartment or house owners.

Device principle

The most common designs are those with an electromechanical lock. It is fundamentally similar to the usual one, but the main difference remains the control of the mechanical system and the electrical component. To activate the latter, one of the following options can be used:

• keyboard code;
• key;
• magnetic card;
• button on the control panel.

As soon as the electronic device receives the signal, the lock is unlocked. This design provides the following advantages:

• independence of the system from the availability of electricity (this is a big drawback of conventional electromagnetic structures);
• the ability to open an electric lock in the “classical way” if it is violent;
• ease of implementation of an electric locking mechanism into the smart home control system.

Types of electric locks

Locking mechanisms can be classified according to the principle of their design and operation. The first parameter implies dividing electric locks into two groups:

• Invoices that are installed on the door leaf do not require opening it. Another advantage is the presence of a forced opening device, which is important in the absence of power supply.
• Mortise electric locks can be attached to the intercom and allow you to install additional deadbolts to increase the reliability of the entire structure.

The operating principle of an electric lock determines how the locking mechanism is locked and unlocked. According to this parameter, all options are divided into three groups:

• electromagnetic;
• electric motor;
• electromechanical.

Electromagnetic lock

The principle of operation of an electromagnetic lock is based on a powerful magnet and winding, with the help of which the reciprocal metal plate is held. This ensures low cost and high reliability. Such systems are not afraid of moisture, which allows them to be used as locking mechanisms on a gate or entrance door to an entrance or office building. Among the disadvantages of electromagnetic locks, it is worth noting the need for a constant supply of electricity to hold the door in the closed position. Another disadvantage of these systems is residual magnetization, which creates additional resistance to opening. Ideally, this parameter should not exceed 1-2 kg, which will allow a child to use the door.

When the power goes out, the lock automatically opens, so it is important to provide an additional power source.

Electromechanical

A feature of this type remains its design that is as close as possible to the “classic” version. Inside the locking mechanism housing there is a key cylinder and a system of levers that can be actuated by a small electromagnet. This design allows you to open the door from the outside with a key, and from the inside with an intercom or a button located on the body.

Electromotor

The lock of this design remains the closest relative of electromechanical ones. The main difference remains the use of an electric motor as a drive source, rather than a magnet. To increase the durability of such a lock, there is a smooth opening system, which reduces the load on the drive. The higher complexity of these locking mechanisms determines their high cost, which must be taken into account when choosing.

What to look for when choosing

There are hundreds of models of electric locks for entrance doors and gates on the market today, so it is important to know the following points when choosing a specific option:

Installation location. Mortise locks are usually installed on entrance doors, but a more affordable, but no less reliable, overhead electromagnetic street lock is suitable for the gate.

The magnitude of the “pull-off” load(this point is relevant for electromagnetic locks). For light interior doors, this parameter can be within 150 kg, for standard entrance doors weighing up to 100 kg, the “tearing” load should already be 300-500 kg, and for heavy structures it should already be more than a ton.

Control method. By default, the magnetic lock connection diagram provides the ability to control it remotely. For this purpose, integration into the overall “smart home” system can be used or unlocking can be provided by pressing a button on the lock remote control.

Can be used without power supply. In the absence of power, some options can automatically unlock or, on the contrary, block the electric lock. To prevent this, it is necessary to provide for the possibility, depending on the specific case, of having a backup power supply, opening the lock with a key, and so on.

Manufacturer. Today, the market offers a wide range of manufacturers of electromagnetic locks, among which the most popular are the following:

• ISEO (an Italian company whose locks can be opened with a regular key);
• CISA (a feature of the company’s products in special coded keys supplied with the lock in a sealed form);
• Mingyang (the Taiwanese brand offers on the market electric locks for doors that open inward and outward, which are guaranteed to work at temperatures not lower than 10 degrees below zero, which must be taken into account when choosing).

Video

Installation

If you have the proper skills, installing a magnetic lock on a gate or an electric locking mechanism on the front door does not take more than 2-3 hours. Installation usually takes place using a T-shaped corner connecting the frame and the profile. To do this, places for drilling mounting holes are pre-marked. This must be done very accurately and carefully to prevent subsequent modifications. After drilling the mounting holes, it is necessary to arrange channels in the frame for the electrical cable, which will pass from the door leaf into the frame profile. This cable is necessary to supply power and connect to the intercom for remote control of the locking mechanism.

If you plan to connect an intercom electric lock to the control system, you will need to additionally purchase a connecting cable. As the latter, you can use twisted pair or a special combined conductor that has the ability to simultaneously transmit video signals, sound and electricity. The peculiarity of such cables is the presence of several flexible cores of different colors, one of which has a copper braid.

Connecting to an intercom

To connect a video intercom to a gate, you need to focus on the colors and contact numbers of the terminals, which are almost always available on the calling panel and the intercom itself. It is also important to provide a separate power supply for the lock. Here, despite all the simplicity, you should not use a video intercom as a source due to the risk of various malfunctions. When choosing a power supply, it is necessary to take into account the parameters of the locking mechanism itself.

A definite recommendation would be to pre-install the power supply and connect the intercom to the lock “on the table” before installation. This will allow you to immediately check the performance of the system, and if there are problems, quickly make adjustments by understanding the connection process.

Advantages and disadvantages

The increasingly widespread use of electric locks on entrance doors and gates is due to their following advantages:

• maximum comfort for residents of houses, due to the ability to open doors remotely;
• high reliability of systems due to the absence of rubbing elements and relative simplicity of design;
• increased difficulty in counterfeiting magnetic cards and keys;
• resistance to low temperatures, moisture and other external conditions;
• ease of integration of locks into an access control system of any complexity.

At the same time, electric locks are unlikely to completely replace traditional mechanical designs, which is associated with the following disadvantages.

The equipment of a modern home includes reliable door security, and there is a wide variety of designs. Their important element is the locking mechanism, which determines the level of protection against any damage or unauthorized entry. Factors such as the opening method also depend on the type chosen. By installing an electric lock on the front door, you can control the opening remotely. However, this is not the only advantage.

Characteristics of an electric door lock and its types

An electric lock is a modern door component that ensures the security of your home at a high level with the ability to control it using an electrical signal. There are several types of such devices, which differ in the type of closure.

Types of electrical door security devices:

• – it is based on an electromagnetic field, which is created by applying current, with its help the mechanical bar is kept in one position and ensures the door closes;
• – closing depends on the level of protection, the basis is the bolt, it is controlled by a remote control;
• – operation is ensured by a short supply of voltage; energy for such a mechanism is needed only during the process of opening/closing the door.

An electric lock on a mechanical door operates using an electric latch, which is the counterpart of the lock. When a command is received from the key, it unlocks the door without the need to turn the key. Especially popular are locks with an electromagnetic card, which are actively used in office-type premises, as well as banking and secret institutions. They are also actively used on doors to apartment buildings with intercoms. They are opened using special plastic cards, a GSM beacon, touch keys, a signal from a key fob, and also using a special code.

Such locks can provide reliable protection against unauthorized persons entering the premises. They operate by sending a special signal from the remote control, which regulates the opening/closing of the door.

Advantages of electric door locks

The decision to purchase an electric lock for your front door should be based on its characteristics. It is necessary to consider the pros and cons of the devices, since their use should not cause discomfort. Modern protection has the following advantages:

• opening – from the inside is provided by a key, from the outside – a special button, control panel or code;
• simple design characteristics;
• reliable protection from ill-wishers;
• easy control.

However, if you decide to buy an electric lock for your home, you need to take into account the need for a constant supply of current. If there is a power failure, it will be impossible to open it yourself. Design features will require the intervention of a master.

Connecting an electric lock serves as the basis for its further functioning. This should be done by a specialist, as he can guarantee correct installation. In addition, a good master is able to provide good service in the future, if the need arises.

When deciding to purchase an electric lock, price is a key factor. Our portal presents models of different price categories. The cost is determined by the features of filling and filling operation. At the same time, the quality of each model is guaranteed.
