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.
Pay attention! Electromagnetic lock with invoice 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 complexity 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 is locked.
Hidden dial code panel Operating principle
The main element of the door consists of a magnetic strip, which is precisely the locking mechanism. A magnet has a core and a winding. While the door is closed, electric current creates a field that keeps the magnets held tightly together.
When dialing the right combination figures for 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 beep 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.
- The power supply is a device that ensures uninterrupted operation of the 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; it is 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’s worth buying a 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.
It is installed primarily at entrances to premises subject to increased protection, as well as on gates and service passages of enterprises. There are also similar high-security locks, to unlock which you need not only to enter a secret access code, but also to use an additional identifier, for example, a key “tablet”, a plastic card or your own fingerprint.
What is good about a magnetic combination lock?
To the benefits electro magnetic locks opened by entering a secret code on a special panel, the following factors include:
resistance to illegal intrusion- If plastic card or the Touch memory key can be stolen, it is almost impossible to become the owner of a digital code unnoticed. In addition, a door with an electromagnetic lock does not have a keyhole - it cannot be opened with a master key;
reliability and durability– the electronic magnetic device has the simplest design, thanks to which it is able to work without failures or breakdowns for a long time. It cannot jam because it has no moving elements;
different levels access– stand-alone controller included lock system allows you to distribute secret codes for several access levels and set separate restrictions for them;
universal use– electromagnetic combination locks are perfectly combined with any doors and can be used in conjunction with plastic, wooden, glass, and metal doors, both hinged and sliding.

In the 21st century, electronics is replacing mechanics in almost all areas of human activity, including locking devices for entrance and interior doors. Almost every entrance in major cities these days it is equipped with an intercom with an electromagnetic lock, and in office centers magnetic locks on interior doors are common, making it possible to limit the access of different categories of personnel to different rooms. Therefore, it is worth understanding what the principle of operation of magnetic locks on doors is, how they are installed, how to make right choice such a device.
Scope of application
Magnetic locks are now common in households, commercial buildings and government offices. These are the locks that are installed on entrance doors entrances along with intercoms so that residents can open them remotely. In office centers, installing such locks allows you to give different employees access to different rooms - an access card can open only one lock or several at once. Moreover, if an employee is fired, it is not even necessary to take away the key from him - just change the access signature and update the cards of the remaining employees.
Finally, in government institutions Such locks are installed in rooms where particularly valuable items or documentation are stored, since these devices are usually much more reliable than mechanical ones. For entrance doors separate apartments and private houses (with the exception of elite cottages), magnetic locks are installed extremely rarely. There are almost no electric magnetic locks and on interior doors residential buildings. But simple magnetic latches in such cases have been widely used since Soviet times.
Operating principle
And for the serious ones electromagnetic devices with cards or keys, and for primitive latches, the operating principle is based on the mutual attraction of parts with different magnetic charges. In the case of a latch, two are enough permanent magnets oriented so that their opposite poles are opposite each other. The action of electromagnetic locks is based on the appearance magnetic field around a conductor through which alternating electric current flows.
If you give the conductor the shape of a coil, and place a piece of ferromagnetic material inside it (which is usually called a core), then the magnetic field created by such a device will be comparable to the characteristics of powerful natural magnets. A working electromagnet, like a permanent one, will attract ferromagnetic materials, including most ordinary steels. Expressed in kilograms of force required to open doors, this force can range from several tens of kg to one ton.
Most modern magnetic locks are an electromagnet with a control system and a so-called counter plate, usually made of steel. When closed, electric current constantly flows through the system. To open such a lock, you need to temporarily stop the current supply to it. This is achieved using a control system, which usually includes a special reading unit that receives data from a magnetic key, tablet or plastic card and compares it with what is recorded in its own internal memory. If the signatures match, the control unit turns off the current, and the force holding the door disappears.
Often such systems include additional elements, the most common of which is a pneumatic closer, which gradually returns the door to the closed state. Sometimes there are combined variations of magnetic locks with mechanical ones, in which the forces of magnetism are used to hold the moving part (known as the bolt) inside its corresponding groove. These designs do not have the advantages of electromagnetic ones and represent an advanced version of the latch, therefore they are used only for interior doors in homes and offices.
Varieties
As mentioned above, according to the principle of operation, magnetic locks are divided into:
- electromagnetic;
- using permanent magnets.
In turn, according to the opening method, an electronic magnetic door lock can be:
- by keys;
- by tablets (a type of magnetic keys);
- by card (the signature is recorded on a plastic card, which is read by a special device);
- coded (the control device includes a keyboard that allows for entering a code);
- combined (these are found on most intercoms; the door can be opened either by entering a code or using a tablet).
Moreover, if in most cases the key, tablet or code data is compared with data from the device’s internal memory, then models with card access are usually connected to centralized control systems. In this case, each card has its own code that uniquely identifies its owner. When the card is swiped, this information is transmitted to a central server, which compares the cardholder's access rights with the security level of the door they are trying to open, and decides whether to open the door, keep it closed, or even raise an alarm.
Permanent magnet locks are opened in any case by mechanically detaching two parts. In this case, the supplied force must exceed the force of magnetic attraction. If conventional latches are easily opened using human muscle power, then in the case of combined mechanical-magnetic locks, opening systems using force-increasing levers are sometimes used. According to the installation method, a magnetic door lock can be:
- overhead when it is attached to outer part the door leaf and the outer part of the door frame;
- mortise, when both of its parts are hidden inside the canvas and the box;
- semi-mortise, when some of the structural elements are inside and some are outside.
Magnetic latches and combination locks are available in all three variations. With electromagnetic locks, everything is a little more complicated - the options installed on entrance doors usually only come with overhead locks, but for internal doors Along with overhead ones, there are also semi-mortise designs.
Pros and cons
All magnetic locking systems have common advantages:
- the minimum number of moving elements (especially the absence of a locking spring) significantly increases the durability of the lock;
- minimal external wear during operation;
- ease of closure;
- Closing and opening of doors occurs almost silently.
Electromagnetic options additionally have the following advantages:
- possibility of integration with centralized systems security and surveillance;
- making copies of a magnetic key is much more difficult and expensive than for a regular key, which reduces the risk of unauthorized entry;
- enormous closing force, significantly exceeding the capabilities of most mechanical systems;
- Due to the large dimensions of the counter plate, the occurrence of door misalignment during operation almost does not reduce the effectiveness of locking.
The main disadvantages of electronic systems:
- some old intercom systems with combination lock have universal service code access that may be known to attackers;
- For stable operation the system requires constant power supply, since without current flow the door will remain open;
- complexity of installation and maintenance (change of access signature, repair, etc.);
- A reliable electronic lock is still much more expensive than its mechanical counterpart.
Systems based on permanent magnets have the following advantages:
- work without a current source;
- ease of installation.
The main disadvantage of such devices is their low holding force, which limits their use exclusively to interior doors.

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 from different manufacturers may differ in design, they operate on the same principle. 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 standalone source power supply or a regular 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 home, industrial enterprise or territory, to control an electromechanical lock must be installed independent source energy. 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. Main part with magnetic device is fixed directly on the door frame and is powered from a DC voltage source. The locking plate is attached to 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 structure
The electromagnetic lock consists of the following elements:
To power almost any electromagnetic lock you need constant voltage 12 V. 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 term service - 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;
- opportunity remote control 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 supply in the network, therefore for reliable operation such a lock must be equipped with 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 of door leaf:
- for internal doors, a holding force of about 200–300 kg is quite sufficient;
- for massive metal doors such 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 the ability to connect additional equipment to it, 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. These can be entrance doors to any room, fire and emergency exits, etc.
An electromagnetic lock with a controller is installed in a room where high demands are placed on the locking device
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;
- high voltage protection at the input;
- the ability to copy memory from/or to a computer.
Holding electromagnetic 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 have become widespread 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.
Installation of the holding lock does not require high precision 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. But 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, the door automatically opens. Since there are no rubbing parts in the design of such a lock, it has a long service life and is usually installed in rooms 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 plumbing skills and can 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 fix the counter plate, and install rubber washers between it and the canvas. 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 other 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 a capacitor breaks down, which serves to create damped oscillations when the power is turned off, removing the remnants of the magnetic field. To eliminate such a breakdown, you need to connect a 25 V capacitor in parallel to the lock terminals. For most locks domestic production 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 an installation 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.
