Every sane person has a desire to secure their home from intrusion. Mechanical locks, even the most reliable ones, can be broken if certain devices are present. This is more difficult to do with electromagnetic locks. It is easy to handle code panel for electromagnetic lock.

Standard code panel

What is an electromagnetic lock?

This locking mechanism is resistant to hacking, because all its components are carefully thought out. It has a number additional functions, which users liked.

Note! The electromagnetic lock with an overhead code panel is constantly being improved. So, now on sale you can find models with touch screens or with automatic switching on alarms.

But, despite the difficulty for burglars, such a lock is not distinguished by the complexity of the device. Installation and configuration does not require special knowledge. The adjustment mechanism is simple, you can figure it out by carefully reading the instructions. There are various modifications of such locking mechanisms, and the control board for the electromagnetic lock is closed by a code panel, which is made in different designs and is designed for various mounting surfaces.

Is it worth using such a locking mechanism?

To decide whether or not to use such a lock, you should learn about some advantages, including:

Full compliance with regulations fire safety. When there is a power outage, such a lock does not perform locking properties, which facilitates the evacuation process.
Not exposed to aggressive environments or temperatures. It will not “freeze”, as happens with conventional locks when the temperature drops.
It cannot be opened with a master key or other burglar device.
It has no movable parts, which significantly increases the service life when compared with mechanical locks.
This door opening mechanism is indispensable for heavy traffic, because it is easy to use combined with excellent protective properties.
If the code is entered incorrectly, the door will be locked.

Hidden dial code panel

Principle of operation

The main element of the door consists of a magnetic strip, which is precisely what locking mechanism. A magnet has a core and a winding. While the door is closed, electricity creates a field that keeps the magnets held tightly together.

When the correct combination of numbers is dialed within a certain time, the circuit opens and the door opens. In some models it is possible to enter a 12-digit code.

The convenience of such a system is undeniable, but for apartment doors similar options are not used. They have proven themselves best in high-traffic areas.

Code panel: why is it needed?

The key point when installing an electromagnetic lock should be the installation of the control board, because it is responsible for unhindered entry into the room, including the home and office.

This scheme is convenient, because the electromagnetic lock control board and code panel will allow you to forget what it’s like to be on the street with a door slammed from the inside or to lose the key and not get into the house. The main functions include the following:

Provide public and personal access. This is convenient for commercial organizations, shopping centers, gyms.
When trying to select a code, it turns on sound signal and the door is locked.
It is possible to program the duration of the lock activation.

Door mounted code panel

Standard equipment

IN standard kit The coded electromagnetic lock includes the following components:

Magnetic door pads. Depending on the model, it can hold a force within 1000 kg. Installed on doors made of different materials– wood, metal, plastic. The strip is mounted on the corner of the door and frame. There are models covered with white, brown or silver enamel.
A power source is a device that provides uninterrupted operation lock even if the power goes out.
Electromagnetic lock control board and code panel. The electronic board has non-volatile memory, sound and light indication. The code panel consists of buttons that can be touch-sensitive, metal, or plastic. Some models have a hidden dialing device; the buttons are hidden under a flap, making it impossible to see which ones are being dialed even from close range.
The entry button is mounted with reverse side doors.

In addition to basic set It is worth buying a door closer - this mechanism ensures smooth closing of the door.

How to choose?

The safety and reliability of closing depends on the choice of an electromagnetic lock with a code panel. If the code panel will be mounted outside the building, that is, it will be exposed to moisture and temperature, it is necessary to consider options for protecting the housing from moisture. Among different manufacturers options are presented that can withstand a temperature range from -30 to +60 and do not suffer from moisture.

The electromagnetic lock control board is the heart of the mechanism, only when correct setting it will be possible to establish normal work locking device. There will be no difficulties with setup, since each lock comes with detailed instructions. It is important to study it carefully and follow it.

One of the options for protecting a room door or fence from unauthorized opening is to install an electromagnetic lock. Such a device is installed directly on the door, and it is controlled remotely using an electrical signal. Electromagnetic locks are very popular due to their high reliability and work perfectly both indoors and outdoors.

Design and principle of operation of electromagnetic locks

Although electromagnetic locks Different manufacturers may differ in design, but their operating principle is the same. The door closes and opens due to the presence of an electromagnet inside the device. You can control such a locking device by pressing a button or by entering a special code.

The quality and reliability of the lock will depend on the strength of the electromagnet used. The larger it is, the more securely the metal plate holding the doors is fixed.

In the event of a sudden power outage, the electromagnetic lock will not be able to fulfill its intended purpose, so it is recommended to additionally install an autonomous power source or a conventional mechanical lock.

The reliability of door fixation with an electromagnetic lock depends on the holding force of the built-in magnet

To provide reliable protection for a home, industrial enterprise or territory, to control electromechanical lock An independent energy source must be installed. If the main power is turned off, the system automatically goes into offline mode, so the safety of the home will not be threatened.

The operating principle of an electromagnetic lock is simple and clear. The main part with a magnetic device is attached directly to the door frame and is powered from a DC voltage source. The locking plate is attached to the door leaf. When power is applied, the electromagnet is activated and the strike plate is attracted to it, thereby ensuring reliable locking of the door. When you press the button that operates the lock, the power is cut off, after which the plate moves back, allowing the door to open.

Internal organization

The electromagnetic lock consists of the following elements:

To power almost any electromagnetic lock, a constant voltage of 12 V is required.. It may change slightly, but this is not desirable. If the voltage decreases, the holding force of the electromagnet decreases and the reliability of the lock also decreases. When the voltage increases, the winding overheats, which can lead to its failure. High-quality modern electromagnetic locks consume only a few watts, so their installation will not greatly affect the overall energy consumption.

Advantages and disadvantages

Electromagnetic locks have many advantages, which explains their great popularity:

long service life - on average 10–15 years. Ensured due to the absence of moving parts;
large selection of models. They can be mortise, overhead, tear-off or shear;
high reliability. Such a lock cannot be picked using drilling or a master key;
the ability to remotely control the door opening/closing process;
possibility of installation on any doors, including metal, plastic, wood, glass;
simple installation and maintenance;
minimum power consumption - approximately 3–5 W;
ability to work both indoors and outdoors;
affordable price. A simple electromagnetic lock with a hold of 180–300 kg retails for 1000–1500 rubles.

Like any other type of lock, this locking device also has its disadvantages:

dependence on the availability of power in the network, therefore, for reliable operation of such a lock, it is necessary to install an autonomous power supply;
higher cost than mechanical lock, which is justified by significantly greater reliability and ease of use;
the need to have certain skills to work with electrical networks for self-installation.

Types of electromagnetic locks

According to the type of design, electromagnetic locks are:

Depending on the method of opening the door, locks can be:

The choice of electromagnet holding force will depend on the type door leaf:

For internal doors A holding force of about 200–300 kg is quite sufficient;
for massive metal doors this force should be greater - 350–500 kg.

By type of application, electromagnetic locks are:

individual. Such devices are installed in private houses, apartments, offices, etc.;
public. They are used in shops, offices, banking institutions, entrances, etc.

Locks with controller

To provide control of the electromagnetic lock and to be able to connect to it optional equipment, such as a reader, card or key fob, opening button, buzzer, a controller is installed on it. To protect the controller from the negative effects of external natural factors, it must be placed in a special protective housing.

Electromagnetic locks with a controller are highly reliable, so they are usually installed in rooms where high demands are placed on the lock. It can be entrance doors

to any room, fire and emergency exits, etc.

Modern locks with a controller have the following characteristics:

light and sound indication;
locking when selecting a key;
memory capacity of 500 or more keys;
protection against freezing and jamming;
non-volatile memory;
programmable door opening time - 1–15 s;
protection from high voltage at the entrance;
the ability to copy memory from/or to a computer.

Electromagnetic holding locks

The peculiarity of holding locks is that their installation does not require special precision and they are easy to adjust. The main advantage of electromagnetic holding locks is that their operation is practically not affected by the condition of the door. Thanks to his simple device and reliability, such locks received wide use and are usually used in places where there is a large presence of people, when it is necessary to frequently close/open doors.

Typically, retaining locks are installed at the top of the door, which can lead to unwanted deformations on light and fragile panels. In addition, their design is susceptible to the phenomenon of residual magnetization. Therefore, experts do not recommend using retaining devices on canvases that open inward or in both directions.

The holding lock does not require high precision when installing and is easy to adjust

Slide locks

This lock works by moving a flat anchor. The main advantage of such models is that they can be installed inside the door frame or leaf. The disadvantage of such structures is the need to accurately maintain the gap between the interacting parts of the lock.

The sliding lock can be installed inside the door frame

There are several basic parameters that you need to pay attention to when choosing and operating a sliding electromagnetic lock:

shear load, it can be from 100 to 1200 kg;
holding strength;
degree of security (secrecy);
residual magnetization - when opening the door, the force should not exceed 2 kg. If this value is greater, the lock needs to be repaired.

Coded electromagnetic locks

Their main difference from other types of locks is the presence of a code keypad, which may also have a card/key fob reader. Thanks to this device, you can open the lock in several ways:

by dialing a special code;
by dialing code + card;
card or keychain.

The combination lock, like other electromagnetic models, meets fire safety rules, since when the power is turned off, automatic opening doors. Since there are no rubbing parts in the design of such a lock, it has long term

services and is usually installed in premises visited by 20 or more people per day.

The electromagnetic combination lock has a keyboard for entering the user identification code

When choosing an electromagnetic lock, you need to pay attention to the following criteria:
Type of door leaf.
Terms of Use. If the lock will be used outdoors, it must be protected from the negative effects of moisture and not be afraid of temperature changes.
Installation method. Availability alternative source
nutrition. If it is not possible to provide autonomous power, then in the absence of electricity the lock will automatically open.

Holding power. The larger and more massive the doors, the greater the holding force of the electromagnet should be.

Installation of an electromagnetic lock

If you have basic locksmith skills and know how to work with electrical circuits, then installing such a lock yourself is not difficult. Before you begin work, you need to decide on the following parameters:
how the canvas and the box are located - the box can protrude or be flush with the canvas;

whether the doors open inward or outward. The most common option is when door frame has a protrusion from the edge of the canvas when closed, 5–6 cm wide and it opens outward. In this case, problems with self-installation

an electromagnetic lock does not occur, but first you need to purchase all the necessary tools:

The installation process of an electromagnetic lock is divided into two stages: installation of the strike plate and the magnet itself. The sequence of work will be as follows: Installation of the strike plate. Usually, the electromagnetic lock kit includes a template for its installation along with the strike plate. First, they decide on the mounting location - it is necessary that the bar hits the electromagnet when the door is closed. After this, a stencil is applied to the door leaf and holes are made for the bolts. Then using fastening elements The strike plate must be able to move slightly; this is ensured by rubber washers, with the help of which it can occupy the required position relative to the electromagnetic lock.
The strike plate must precisely align with the electromagnet when the door is closed, so it is installed on rubber washers to allow adjustment
Unscrew the locking screws on the lock. Using the hex key that usually comes with the lock, unscrew the screws securing the lock bar.
The fastening strip is used to fix the lock on the door using bolts; it is supplied screwed to the body
On the canvas opposite the counter plate, mark the place for mounting the magnet.
Flat mounting strip The lock is securely fixed to the box.
The lock bar is fixed to the frame using self-tapping screws
The magnet is attached to the bar in the reverse order - first using a hexagon, after which the locking screws are screwed in.
An electromagnetic lock is fixed to the bar installed on the box, and then the locking bolts are screwed in
Check for correct installation. The doors should close tightly, and the lock should not hit the striker.
Connect power and others electronic components in accordance with the diagram in the instructions.
All connections of the components of the access control system, under which the lock will operate, are made according to the diagram included in the kit

In the case when the doors open inward and the leaf is flush with the frame, special mounting angles must be used to install the lock.

Repair of electromagnetic locks

Although the electromagnetic lock has a long service life and high reliability, like any other equipment, it can fail after a while. The main factors that can lead to lock failure:

human - improper operation of the lock;
natural - negative impact external factors, which leads to damage to wiring and fasteners.

The main failures of an electromagnetic lock are associated with weakening or loss of the holding force or with the appearance of residual magnetization. The force may disappear due to a break in the wires that supply power to the lock, a breakdown of the power source, or a failure of the electromagnet coil.

The main malfunctions of the electromagnetic lock and how to eliminate them:

Coil repair. To check the functionality of the electromagnetic lock coil, you need to use a tester. The resistance should be several tens of ohms, it all depends on the model and power of the lock. If the resistance does not correspond to the parameters stated in the instructions, the coil is replaced, and if the block is monolithic, then the entire magnet.
Residual magnetization. It appears when the capacitor breaks down, which serves to create damped oscillations when the power is turned off, removing residues magnetic field. To eliminate such a breakdown, you need to connect a 25 V capacitor in parallel to the lock terminals. For most domestically produced locks, a capacitor capacity of 220 µF is sufficient, and for foreign-made models, the capacitance can be from 220 to 1000 µF and is selected individually.
Coil break. This malfunction can be eliminated by replacing the coil or restoring its functionality in specialized workshops.

If the electromagnetic lock has been installed correctly, then usually no problems arise during its operation. You just need to stick to simple rules

equipment care:
During operation of the lock, it is necessary to periodically check the condition of the plate. Under the influence of moisture, plaque may appear on it, which leads to a weakening of the holding force;
It is recommended to periodically check the fastenings of the lock and strike plate. Over time, under the influence of loads, the screws may weaken, so they must be tightened periodically;

When using a lock with a controller implemented as a separate device, you must have a master key. It is used to encode cards. It is recommended to store it in a mounting box, this will avoid coding problems that arise when one of the users loses the access card. It is recommended to place the controller itself in a sealed bag to protect it from moisture. It is unlikely that today you can surprise someone with a magnetic lock with magnetic key

. We find various models based on the principle of magnetic waves almost everywhere. Nevertheless, the industry for the production of such devices is developing successfully, and manufacturers every year offer new models of more sophisticated and more reliable electromagnetic locks.

Features and differences Distinctive characteristics Magnetic keys are considered to be efficient, quiet, reliable and easy to use. Thanks to design features that eliminate moving and rotating parts, these devices have long term services. The reliability and efficiency of magnetic such devices has been proven by many years of service life under any conditions. weather conditions and in different situations. Systems based on the wave principle are in many ways superior to other types of locking mechanisms.

and passive

Operating principle locking devices This type is based on the interaction of magnetic elements. For their operation, the lock design may additionally provide power supply. Thanks to the action of an electromagnet, which attracts the return bar mounted directly into the leaf, the front door remains in the closed position. Only when you press a special button or under the influence of a magnetic key does the current supply briefly stop and the leaf opens freely. Such devices are widely used in the field of protection of objects requiring additional control and visit restrictions.

In some locking models magnetic devices Only mechanical interaction is involved. Such models are often called passive. Of course, they do not have special holding power, but they have become widespread in certain areas. Simplified samples are usually used for closing cabinets or as magnetic ones. Very often, similar mechanisms are used on wallets, purses or women's bags. However, these systems are unlikely to be suitable as means of reliable protection and security of the premises.

Design of electromagnetic locks

Outdoor locking devices or models used indoors have simple design. It is based on the use of a metal plate and a steel core in a copper winding, installed in a special housing.

The body of an electromagnetic lock is usually made of aluminum or steel. In its production, the use of special plastics is allowed, but even the use of high-strength materials does not guarantee the long service life of the lock.

Equipment

To install a magnetic lock with a magnetic key, you will need not only the device itself, but also some additional attributes and mechanisms. Exactly from auxiliary elements The reliability and effectiveness of the lock will depend. A complete set of an electromagnetic locking device must include:

The lock itself, which is sold complete with a reverse metal plate and electrical wiring to connect the device to an electrical source.
The controller required to control the locking mechanism. It is through this element that all other attributes of the castle are connected. The main function of the controller is to provide imitability for the electronic key chip.
An information reader required to open a door using a special magnetic key.
A set of keys programmed to a specific frequency.
A special button, when pressed, you can open the door from the inside.
Power unit. Additional batteries will ensure correct operation of the locking device during power outages.

Classification

Taking into account certain design features, electromagnetic locks are usually divided into two groups: systems that have a sliding type of opening, and devices that operate on a pull-out type. Like any other locking mechanisms, electromagnetic devices are divided according to the method of installation on the door leaf. These can be mortise or rim magnetic locks with a magnetic key. Devices can be classified according to geometric characteristics: They have a rectangular mechanism or are designed in the form of a rounded electromagnetic system.

Choosing a locking system

When choosing a door lock with a magnetic key, Special attention should be given overall dimensions, mass and technical equipment devices. Modern electromagnetic locks are compact devices, but their adhesive force can reach thousands of kilograms. Such devices are suitable for massive and strong doors, since when installed on not very strong leaves made of plastic profiles, can deform and cause the door to jam. Therefore, based on the weight of the lock, the strength of its impact and the design features of the door leaf, the locking system should be chosen carefully.

Myths about electromagnetic locks

Recently, conversations about how to open a magnetic lock without a tablet key have become increasingly relevant. In fact, electromagnetic locking devices do not have the function of entering a universal numeric code. This may differ only from some models of the Vizit system, which in the factory settings have functionality that allows opening the front door without using a magnetic key.

Doesn't exist and universal keys, opening any electromagnetic device. They simply cannot exist because the locking systems and their operating principles are too different.

Special keys for such locks cannot be demagnetized due to exposure to strong magnetic fields. However, they are easily damaged, so they require careful handling.
