Magnetic door locks for interior doors. Magnetic door code locks

Convenient functionality reliable operation combined with a well-thought-out design, versatility of use. This is how you can characterize magnetic lock on the door, confidently pushing back mechanical structures. Manufacturers of door “devices” offer versions for both entrance and interior doors.

The operation of the device is based on physical property attraction of magnets with different pole charges. This force is sufficient to hold the door in the closed position. However, the ability to hold the striker plate in different lock models may vary significantly depending on the strength of the magnet.

The holding force is expressed by the “pull-off” mechanical load, expressed in kilograms. The production step is 50–100 kg. In nomenclature model range There are mechanisms for 100, 150, 200 kg. Meet powerful models from 1000 kg retention.

The magnetic door lock operates due to the strong magnetic field created by electricity. Voltage is applied to the coil. A field is formed that attracts the second part of the castle.

Equipment

For entrance, interior designs, fencing of private houses, gates, standard components are similar:

• a magnet of a certain power, the operation of which is triggered by electric current;
• return metal plate attracted to the magnetic plane;
• connecting cables;
• set of fasteners.

Auxiliary equipment includes:

• An uninterruptible power supply device to maintain the operation of the lock during a power outage.
• Connection controller additional equipment. On systems with remote control additional installation not required: the controller is already built into the keyplate.
• Closers for smooth operation of the magnetic lock. They eliminate the knocking of the valves and significantly increase the service life of both the locking mechanism and door leaf.
• Intercom. Complements the magnetic lock on the street front door. Mounted directly on the entrance doors of entrances and cottages. With its help, you can see the person who has arrived and open the mechanism remotely.

The owner chooses additional “options” for the lock himself, purchasing the necessary technical equipment.

Types and principles of operation

Magnetic latch Electromagnetic lock Electromagnetic lock

Passive devices . The category is represented by simple low-power mechanisms that operate without electrical power. Passive magnetic devices only hold the doors closed, but do not lock them.

Installation is justified for interior doors. In fact, they are a continuation of furniture magnetic fittings from the times of the USSR, redesigned for new tasks.

Simple models without latches consist of two plates (metal and magnetic). When the door moves, they close/unlock. To open, just pull the handle. The latch mechanism is more complicated. Turning the door handle moves the plate away from the magnetic part - the door opens.

Other category – magnetic lock And, that require a power connection. The power of some models reaches 1 ton, so the main purpose of electromagnetic mechanisms is the access control of entrance doors. The composition contains mechanics and electromagnetic elements. According to the method of fastening on the canvas, the following are presented:

• Overhead mechanisms - secured with corners. Door knob independent of this type of lock.
• Mortise lock installed in the door leaf.
• Semi-mortise, when part of the lock protrudes above the level of the door.

Electrical voltage is required to hold the door structure in the closed position. A short-term loss of power occurs when entering a code combination of symbols on the lock panel, or using a magnetic key. At this time, the magnets open.

Advantages

• The design has a minimal number of moving elements, which increases the service life of the lock.
• Technically, the door components hardly touch each other, so the parts do not wear out or become deformed.
• Changing the spatial geometry of the door frame (warping, shrinkage) does not impair the functionality of the magnets.
• There is no need to monitor whether the door is closed: the magnets act as “closers”.
• Silent operation of entrance doors: no clicks when closing/opening.
• Magnetic locks are perfectly combined with home security and security systems;
• Installing a magnetic lock on the door of the central entrance or entrance reliably protects against those who like to disturb public order from entering the premises.

How to choose the right device

A lock is a device of purely functional use. This makes it necessary to “dance” when choosing specific model. General selection parameters:

• application option - public or individual;
• principle of access control;
• design features of the door leaf;
• use in composition burglar alarm premises;
• compliance with fire safety standards.

The property of a magnetic lock to automatically open when there is no power is important condition fire safety– quickly provide escape routes. Therefore, it is optimal to install magnetic locks on door designs fire exits.

We select the power of the lock “by pull”

• For lightweight interior and office doors, mechanisms with magnets of 150–300 kg “tear-off” will perfectly cope with their tasks.
• Standard entrance doors with impressive weight (entrance doors, front doors for private homes and organizations) will require a lock power of 300–500 kg.
• Oversized steel doors enterprises, storage places commodity values must be equipped with locks with increased tearing force: 500–1000 kg and even higher.

Before installing the magnetic door lock, it is necessary to correctly determine the required “pull-out force”. You should not install locks with powerful magnets on lightweight doors: the door leaf may become deformed and residual magnetization may appear. Installed option with a small pull-out force for heavy doors, it simply cannot cope with the access protection function.

Installation

If you need to install a passive magnetic lock on a door, you can carry out the work yourself by brushing up on the “theory” on specialized websites. The overhead mechanism is very simple to operate, since installation does not require drilling holes.

Installation of a rim lock is carried out as follows:

• on door frame mark the location of the castle;
• appropriate markings are applied for the counter plate;
• a stencil is applied (usually included in the kit), along which the bases for fasteners are drilled. A lock will have to be installed on them;
• the mounting plate is installed and fixed;
• the place where the magnetic base is attached is marked;
• The operation of the locking system is checked.

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, allowing you to limit access different categories 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.

Application area

Magnetic locks are now common in households, commercial buildings and government offices. These are the locks that are placed on the entrance doors of the entrances along with intercoms so that residents have the opportunity to 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. Magnetic locks are so far rarely installed on the entrance doors of individual apartments and private houses (with the exception of luxury cottages). Electromagnetic locks are almost never found on interior doors of 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 of a magnetic field around a conductor through which an alternating current flows. electricity.

If the conductor is shaped like a coil, and a piece of ferromagnetic material (which is commonly called a core) is placed inside it, 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 that 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);
• on the card (the signature is recorded on 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 the outer part of 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.

Advantages and disadvantages

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 a universal service access code that may be known to attackers;
• For stable operation of the system, a constant power supply is necessary, since without current flow the door will be in the open state;
• 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.

Need for protection own property has existed throughout human history. The modern period of development of society is no exception to this rule.

That is why engineers are constantly working on creating such locking mechanisms on doors that could reliably protect this or that object from the encroachment of third parties. One such mechanism that has now gained significant popularity is the magnetic lock.

A magnetic door lock is a locking device whose operation is based on the principle of magnetic interaction between two elements.

Such a mechanism can be installed on a wooden, plastic or metal door.

Attaching magnetic locks to the door can be as follows:

• overhead (using a set of corners);
• mortise (without protruding parts);
• semi-mortise (with a small part protruding from the plane of the door frame).

The type of locking also varies.

Some models are equipped only with a magnetic device, while others are equipped with a magnetic-mechanical device.

Why are they needed and where are they used?

Magnetic locks are used today on the doors of real estate for various purposes.

Among them, first of all, it is worth highlighting the following:

• offices;
• manufacturing enterprises;
• apartments;
• separate rooms;
• the shops;
• warehouses;
• garages, etc.

The need to use magnetic locks is due to their advantages.

Such locking devices are highly reliable and high level protection.

How it works: device and principle of operation

Structurally, a magnetic lock uses two important functional parts: a metal plate and the electromagnet itself.

The latter is attached to the end side of the door frame.

The operating diagram of such a device is quite simple:

1. To the magnet winding constant mode electricity is supplied.
2. A powerful electromagnetic field gradually appears around the magnet.
3. The magnetic field attracts the metal plate located on the door leaf with significant force.
4. The door is eventually locked securely.

To open the door, a person needs to press a special button.

It provokes a release of electrical voltage, which affects the corrective functionality of the locking mechanism.

After the current supply is stopped, the electromagnetic field disappears. Immediately after this, the door becomes free to open.

Existing types

Today there are several main types of magnetic door locks.

According to their principle of action, they are as follows:

1. Passive.

Such devices operate without the need to connect them to the power supply network.

That is why their strength is quite small.

As a result, such locks are used to lock cabinet doors, close handbags, etc.

2. Active.

Operating principle of this device based on an electromagnet and a counter (armature) made of metal with high magnetic permeability.

These mechanisms are used to lock doors.

Experts also separately highlight magnetic locks for entrance and interior doors.

They differ from each other only in the strength of their action.

The former are considered much more powerful and reliable.

Reviews of magnetic locks: pros and cons

The main advantages of magnetic locks that users note are as follows:

• absence of any moving elements;
• simplicity of design;
• ease of connection to an electronic lock;
• high level of security in case of emergencies (the lock automatically turns off without preventing people from evacuating the building).

Like any other lock, the magnetic type of locking mechanism has its disadvantages, such as:

• the need to ensure reliable and uninterrupted power supply;
• big dimensions and significant weight.

If an attacker has entered a room protected by a magnetic lock, he can easily carry out certain manipulations that allow him to re-enter the room in the future.

This only applies to models that are not equipped additional funds protection - sensors, controllers, etc.
