An electronic lock is an access restriction device, the operating principle of which is based on the control of electromechanical or electromagnetic locking mechanisms through the timely supply of power. Control of controller signals is carried out by reading information from magnetic cards, Touch Memory keys, biometric readers, keyboard typing, as well as by sending a signal from remote controls via radio signal. The main advantage of using such systems is the ability to quickly control access, without forming queues at the entrance, with preset parameters. Electronic locks are divided by type of installation: overhead or mortise. Rim locks are installed, if possible, inside the protected premises; mounting angles for fastening are often used, which are not always included.

Differences in the type of opening.

1. Unlocking using a magnetic card or key fobs. To open the locking mechanism, identification of the “key” is required. Each card or key fob initially has its own code, which is written at the time of installation. It is unique and cannot be changed during the operation of the device. The lock opens after reading the code from the identifier through direct contact with the reader or when the card or key generated by the device is in an electromagnetic field. In a magnetic field, the identifier is activated and begins to transmit a unique code via a signal path. The reader signals that information has been received sound signal or short-term switching on of the light indication. The code is transmitted to the controller and if the combination of the electronic signal matches the stored data in the controller’s memory, an unlock signal is sent.

If more complex controller functionality is required, then a device with control is used software. A series of actions to record the time of entry and exit of certain persons, maintaining a log of visits or other events is carried out by a specially created program.

To open from inside the room (if there is no need to record the exit time), use a button with a reader bypass function. The main board receives a manual opening signal and “gives permission” to unlock the locking device.

2. Opening by entering a code on the dial pad. This type of device is used in heavy traffic and is often installed at entrances. Some modernized devices, to prevent the calculation of combinations of numbers, prompt the user to enter random two numbers additionally displayed on the monitor. To open from inside the room, the “exit button” is also used.

3. Opening using biometric data. In this case, a signal to unlock the closing mechanism is given after identifying certain physiological parameters of a person. The most commonly used is a fingerprint. And if any other identifier (key, card) can be lost or transferred to another person, then the biological parameters remain unique. The data provided by the user is converted by the controller into a digital signal, which is compared with the code stored in the device’s memory.

To control mechanisms electronic locks A voltage supply is required, which is generated by a power source. The complete set of electronic locks can be supplemented with a video intercom with a calling panel.

Electronic door locks

Nowadays, there are many different electronic locks, most of them you can find on our website!

The complete kit should consist of the following components:

Main board (controller or terminal)

Reader (+ TM keys or cards)

Exit button

12V power supply

Electronic locking device

Video intercom with calling panel

The idea of ​​controlling the opening and closing of doors appeared a long time ago. In practice, it has been embodied in electromechanical and electromagnetic locks controlled by push-button remote controls with a set of digital codes. The most wide application found such locks in the fencing of entrances residential buildings from someone else's penetration.

The principle of opening (locking) the door in these locks is based on physical law electromagnetic induction. IN electromechanical lock when voltage appears in the coil, the lock core is pulled into the coil (the lock is open). IN electromagnetic lock it’s the other way around: when an electrical signal appears, the locking element of the lock becomes a magnet and attracts the strike plate (the lock is closed).

The main disadvantage of electric door locks was and remains the dependence of the lock's performance on electrical supply, that is, the presence of a working electrical circuit at the site.

Hence the bulkiness of such locks, complex installation with necessary installation electrical wiring.

Electronic lock with chip key

An evolutionary development of electric locks has become an electronic lock with a chip key. Electronic locks have long been familiar from opening doors using entry cards in hotels and offices.

Modern advances in microelectronics reduce not only mobile phones, but also everything that can be controlled by a microprocessor. Door locking systems and electronic locks with a chip are no exception.

You can open a lock with a chip using a card, key fob, bracelet, or any accessory into which a chip can be installed. I am sure that electronic locks that open with the touch of a smartphone will soon become widespread.

Electronic locks are distinguished by their compactness, the possibility of a wide variety of programming, remote control, the ability to control opening/closing and all the other delights of an ACS (access control system). And most importantly, electronic locks do not require installation electrical circuits nutrition. All electronic locks operate independently from batteries. A set of batteries is enough for 20,000-30,000 openings.

The first consumers of electronic locks were hotels and advanced offices. As electronic locks and access control systems became cheaper, fitness centers and hospitals joined electronic locks. Today, electronic locks are available to individuals and the largest electronics manufacturers do not hesitate to produce multifunctional, inexpensive electronic locks suitable for individual use.

Keys to electronic locks

There are several ways to control electronic locks:

• Individual. This is the ability of a person to open a lock using a card (contact or contactless), a key fob, a remote control, via GPS, or a fingerprint (eyeprint) (biometric opening).
• Remotely. This opportunity allows you to tie every electronic lock building (system) into a logical chain of control and management from one or several administrative points.

It is worth noting that remote and individual control are used in tandem and are common in public buildings(offices, hotels, fitness centers).

Complex and simple electronic locks

Electronic locks, like any other device, are available from simple (cheap) to complex (expensive) options. Electronic lock on a door in a cabinet or on a drawer office furniture can't be expensive. Such locks are miniature and inexpensive, although they include all the delights of access control systems.

More complex electronic locks feature several opening methods (card, key, sensors), the ability to be programmed for collective access (20-70 keys), emergency mode, built-in alarm systems.

Buy electronic locks for installation on the door in Moscow Available in the online store Technical Laboratory. Electronic locks differ from conventional electric locks by the presence of a built-in ACS controller. Most models also have code panel and a card reader, turning them into completely standalone devices. When installing such electronic locks on the entrance or interior door no need to connect readers or power. They are powered by a set of batteries.

Design

Depending on the installation method, electronic door locks can be fully overhead or with a mortise part. Some overhead models are used as an addition to already installed mechanical locking devices. This is a simple way to automate the entry point without replacing the mortise part.

The main system of smart locking devices is electromechanical, with a retractable steel bolt and/or latch. If you need an electronic magnetic lock, take a closer look at ours or ones similar in purpose.

A smart electric lock can be made classic lever handle, as in Ironlogic Eurolock models. In Samsung devices, you need to press or pull the handle, depending on the model. Electric locks completely hidden in the door leaf are called “invisible”. They may have an overhead part on the side of the room, but from the outside there will be no signs of installation.

Code or card

When choosing a smart door lock(smart lock in English version) define the main authorization method:

• Code. Convenient when you need to organize passage through a door for hundreds of people. Buying cards for everyone that are quickly lost is not always profitable. Electronic combination lock convenient to install on front door to an apartment, especially if children live in it.
• Cards. RFID cards and key fobs, as a way to open electronic door locks, have become widespread in hotels, offices, fitness centers, and swimming pools. Visitors can get a temporary card, which expires automatically after a certain time.

You can buy a Samsung smart lock that combines both opening methods: code and card. Other manufacturers also have such models. You can also find devices that open via radio through an application on your smartphone.

Tamper proof

Opening Samsung electronic locks designed for entrance doors is comparable in complexity to mechanical ones. If a break-in attempt occurs, such smart devices can trigger an alarm and transmit a signal to the security system.

To make it more difficult for an attacker to guess the code, Samsung engineers recommend using the keyboard as evenly as possible. Come up with an easy-to-remember combination, with as many a large number different numbers. Then the keys will wear evenly.

Control via phone app

Controlling an electronic lock through a program on a smartphone or tablet opens up a number of new use cases:

• Remote opening. When relatives or a courier come to you with an order from an online store, you can open the door remotely through the application. Opening the door from a smartphone is convenient for hostel owners.
• Setup via smartphone. In some models, it is possible to change the electric lock settings, set new code via the application.
• Status information. The electric lock will warn about low battery charge, attempted burglary and other events.

The price of an electronic smart door lock depends on the reliability and number of functions. When choosing a locking device for your front door, you should not skimp on strength.

Every owner of a residential or office space dreams of reliable protection of your property. The best way to solve this problem is with an electronic lock on the front door, which does not have a key hole, which means it is almost impossible to pick up a tool for breaking.

Standard equipment for electronic lock

Locks with electronically controlled consist of several elements, usually included with the device when it was purchased. The main elements include:

• locking device. Can be installed inside door leaf (mortise lock) or on the surface of the door (rim lock). The locking mechanism consists of a housing, inside of which there are bolts that hold the door in place. closed position and an electric motor with which the crossbars are driven. The lock body may provide for the installation of a door handle;

• striker plate installed on door jamb and necessary to hold the crossbars in the closed position;

• control unit. The block consists of a device that processes signals for opening and closing the locking mechanism and a controller that serves to control the lock, independently encode the keys and combine the component parts of the mechanism into a single system. Batteries are built into the control unit to ensure the lock operates in the event of a power outage;

• the block is connected to a constant current source ( electrical outlet) network adapter.

• a device for reading information from a key. Electronic locks can be biometric or built-in invisible locks. The electronic combination lock opens when the code is entered on the panel. The biometric lock is activated by recognizing a fingerprint or retina. The invisibility lock can be opened by a signal transmitted by a key fob, card, cell phone and so on.

• a set of keys (key fobs, cards).

• mounting bolts of different sizes.

Additionally, the electronic lock can be equipped with a closer, which allows the door to open and close smoothly, which increases the service life of the locking mechanism and is connected to an intercom, which allows you to open the door remotely.

Installing an electronic lock

According to the installation method, electronic locks are divided into two types:

• overhead devices;
• mortise devices.

Overhead locks are installed on the surface of the door leaf, and mortise locks are installed inside the door.

Installation of an electronic lock

Rim locks are mainly installed on metal doors, on the gate or .

To install an electronic lock, you will need:

• marker, pencil, tape measure, corner. This set of tools is necessary for marking the plane of the door at the installation site of the main mechanism;
• electric drill with a set of different drills;
• screwdriver

The first stage of installation begins with the installation of the locking mechanism. To do this, a number of actions are performed:

1. in the selected location (most often the locks are installed at a distance of 90–110 cm from the floor level), markings are applied to the door leaf. At the same time, the locations of the locking mechanism housing and fastening points are indicated on the door;

Markings on the door can be made by attaching the lock body to the door leaf or by first drawing a layout of the device.

1. the intended holes for fastenings are drilled. In this case, the diameter of the drills used must correspond to the diameter of the fastening bolts;

1. a through hole is drilled in the door to connect the device body and the reading mechanism;
2. The lock body is installed and secured in the marked area.

The second stage of installation is the installation of the locking plate, that is, the device that will hold the locking bolts. Installation of the striker plate is carried out in the same way as installation of the housing according to the plan:

1. Markings are made on the door jamb. When determining the location of the strip area, the location of the lock must be taken into account. It is best to close the main mechanism and mark the location of the crossbars. It is also necessary to mark the mounting locations of the device;
2. holes for mounting bolts are drilled;
3. the counterplate is fixed.

The crossbars should fit smoothly into the striker. Tight entry and excessive friction are not acceptable.

The third stage of installing a lock yourself is to install a reader and other necessary equipment. In this case, you must be guided by the following rules:

• the reading device is installed on the outside of the door, as close as possible to the lock, since in the case of contact opening, this mechanism must be connected by wires to the locking device;
• the control unit that connects to the network adapter is located near permanent source indoor food;
• It is advisable to place the connecting wires in specialized boxes or corrugated hoses. This will help protect the appliances from moisture and give the door an aesthetic appearance.

Example of installing an invoice electronic lock discussed in detail in the video.

Installation of an electronic mortise lock

Installing an electronic lock by cutting into a door is somewhat more difficult, since special niches for the body and striker must be drilled in the door leaf and jamb, respectively. The following scheme is provided for the formation of niches:

1. door leaf. This improves the convenience of working;
2. the dimensions of the niche are noted, which should be 2–3 mm larger than the dimensions of the lock;
3. using a drill, chisel, hammer or other equipment, a part of the door leaf and jamb is removed;
4. Uneven surfaces are smoothed out after work.

How to connect an electronic lock

After the lock body is installed on the door and everything necessary equipment, you can start connecting it. In most cases, the device connection diagram is included with the lock. If there is no diagram, then you can follow the following instructions:

1. the control unit contains a controller to which all equipment must be connected: a locking mechanism, a reader, and so on. For this purpose they are used electrical cables supplied with the lock;
2. the locking device is connected to the opening code reader;
3. then all system components are connected to the corresponding terminals of the controller;

1. the power adapter is connected;
2. the functionality of the mechanism is checked.

If you cannot connect an electronic lock yourself, then it is better to seek help from specialists.

Electronic locks belong to the category of the most reliable locking mechanisms. A significant drawback of the devices is the inability of the lock to operate correctly without affecting electric current. For this reason, it is recommended to install two locks on the front door, one of which is electronic and the other mechanical.

An electromechanical or electronic lock on the front door is business card modern systems security and access control used to equip residential premises, including life support systems " smart home" Such devices are far from new - most front doors have their modifications installed, which can only be opened with a contactless key, which sharply reduces the possibility of strangers entering the entrance.

Benefits of use

Particularly popular among city apartment owners is a digital lock on the front door, the main advantages of which are:

• the ability to install most models with your own hands;
• high level of security provided by several levels of protection;
• an electronic lock in combination with an electromechanical lock is not inferior in reliability to manual deadbolts;
• available on the market in free sale Electronic locks can be installed anywhere on the door panel or outside of it.
• possibility of opening and closing different key– plastic card, remote control, digital contact key fob, using a smartphone.

Even professional burglars who own modern technologies and tools for unauthorized access (including digital master keys), they prefer to avoid apartments if an electronic lock is installed on its front door.

Types of castles

Today for household use are issued various types devices for restricting and controlling access, which are called “electronic locks”. The concept itself includes many products, the main difference of which from traditional constipation is the absence metal key, who “has a habit” of getting lost. Today, for do-it-yourself installation on the entrance doors of residential premises, the following are of greatest interest:

• electromechanical locks with combined or coded opening that can be installed on entrance gates and gates, room, access and apartment entrance doors;
• digital devices that can be opened using plastic card with a magnetic stripe - identifier or electronic key fob;
• an invisible electronic lock that does not have a key hole, keypad or information reading device, controlled remotely using a remote control or mobile gadget using wireless IT technologies;
• biometric systems that provide controlled access to a protected area by reading a fingerprint or scanning the retina.

Design features of various models

Today, the most common combination electronic locks are push-button type, which do not require any key, and are equipped with most entrances. multi-storey buildings. Also, these devices are installed inside offices to provide access to a certain category of persons.

In this case, the possibility of recording working hours and access control is realized.

Structurally, a combination digital lock can be:

• electromechanical type;
• electric with magnetic deadbolt.

Based on the installation method, this category of products is divided into mortise and overhead devices. At the same time, overhead models are more convenient for do-it-yourself installation. The main advantage of a digital combination lock is considered to be an ultra-high degree of protection of the premises from unauthorized entry. It is almost impossible to find a code for it, digital master keys do not work on it, and it takes a lot of time to crack an electromechanical deadbolt short time does not seem possible.

Owner country house can easily install with your own hands household model of this product on the entrance gate or door, as well as equip any outbuilding on your site. The simplicity of design and reliability of electrical and electromechanical code locks also has its drawbacks, the main one of which is the impossibility of opening the lock, if it breaks, without using a kit metalworking tools. Simple (cheap) models limit the ability of owners to access in the absence of mains voltage.

Digital lock with key card

Today, digital locks are becoming increasingly popular; they can be opened using a plastic card, similar to a bank card. The technology for reading identifying information from magnetic tape (strip) has been sufficiently developed and household locking devices This category is quite reliable in operation.

To improve safety, electronic circuit control is supplemented with a powerful electromechanical lock.

An electronic lock with a contact, programmable key fob has a similar principle of operation. However, despite high degree development of circuit solutions, these models have the following disadvantages:

• high complexity (for some models impossibility) of installing the lock yourself;
• the possibility of failure of electronic chips due to voltage surges or power outages cannot be ruled out;
• sensitivity of the magnetic strip to external contamination;
• If the electronic key card is lost, its restoration may require reprogramming the device.

Invisible locking devices

Modern electronic invisible locks are activated remotely. In this case, the “key” is either an electronic key fob (control panel) or a mobile gadget. In the latter case, the signal from the smartphone through the operator mobile communications or satellite communication is sent to the control unit, where it is identified, followed by the locking mechanism.

In the West, biometric copies have appeared that do not require entering a digital or alphabetic code into touch screen, which use the fingerprint of the owner of the premises. Of course, it is impossible to make such a digital lock with your own hands. However, using it ensures greater safety of the living space and provides the user with more comfortable operation.

Constipation design

Despite the variety of models of electronic locks and differences in their functionality, their operating principle and general design are identical. Any controlled access device consists of:

• an electronic unit that reads information and identifies it;
• electromechanical locking, which in most designs uses an electromagnetic bolt.

An electrical signal from the electronic unit is supplied to the control unit, where a voltage is generated to trigger an electromagnetic coil, which retracts the bolt (bolt). The return of the locking plate to its original state is carried out spontaneously, in the absence of tension, due to the return spring.

How the hidden lock works is shown in the video below:

Some owners of residential property, having purchased a complex electronic locking device that has several levels of protection and considerable cost, want to save cash, prefer do-it-yourself installation. In this situation, there are several possible pitfalls:

• most manufacturers with self-installation an electronic lock (especially a digital, remote or biometric) will void the warranty;
• wireless and card controlled access systems require initial programming, which is performed by an employee of a specialized company;
• The constant, ever-increasing complexity of digital locks requires professional knowledge and high qualifications, which many “home craftsmen” do not possess.

As a result, modern castles with electronic stuffing significantly reduce the likelihood of hacking, but to get rid of the disadvantages inherent in this type of equipment, installation of devices is required uninterruptible power supply. If you really buy reliable device with multi-stage protection, you need to find out in advance who will install and debug it - often these are employees of the lock manufacturer.
