Magnetic locks on the door: selection, principle of operation and installation. Magnetic lock on the door: the best protection for the room

Buy electro magnetic locks for installation on a door or in furniture in Moscow, you can in the online store Technical Laboratory.

This type of locking device is widely used, as it is well suited for installation on all types of doors: metal, wooden, plastic. Exist compact models for furniture, used in shop windows, drawers office tables and lockers in fitness centers.

Advantages of electromagnetic locks

Simple and reliable design

Due to its reliability, the installation of an electromagnetic lock is recommended in entrances. It has no moving parts. The current passing through the winding of the coil heats it. ice does not form metal parts do not freeze.

In case of inaccurate closing of the door, the electromagnet is not damaged and does not lose its performance. There are no thin and fragile parts in it.

Simple electromagnetic lock connection and easy installation

In some cases, only a conventional screwdriver is needed for installation. There are no problems with the exact observance of gaps, distortions during installation have a minimal effect. On the effective work electromagnet, small errors during installation practically do not affect.

Versatility

The scope of this type of locking devices is practically unlimited. You just need to choose the holding force corresponding to the mass of the door, select the necessary bracket for mounting.

Manufacturers present a wide range of dimensions of electromagnetic locks, allowing them to be installed both on a heavy front door, and in small drawers of cabinets or office tables.

normally open type

When the power is turned off, the coil disappears and the armature is not held. The door is open and does not create problems when evacuating people from the building.

If it is necessary to ensure that the armature is held even in the absence of mains voltage, install an uninterruptible power supply unit for 12 or 24 V.

Easy integration with ACS

In some electromagnetic locks, an autonomous ACS controller can be hidden right in the case. This can almost always be done in models designed for access doors. The controllers are small, especially when it comes to the compact Z5-R - simple and versatile, to which you can connect an exit button, a card reader or a code panel.

The scheme for connecting the electromagnetic lock to the ACS controller looks like this.

It is convenient to control this type of locking devices from the video intercom entry panel. An intercom kit with an electromagnetic lock can be installed on a wicket or gate.

Electromagnetic locks: the choice of the Technical Lab

The models listed below cover 95% of cases where reliable electromagnetic lock.

• SL-150C differs in small dimensions that allows to use it in trade show-windows, furniture and easy interroom doors.

• ML-180K with holding force up to 180 kg. Suitable for interior doors from wood and plastic. Supplied in two versions: with a bar and a corner. Available in 2 colors: gray and brown.

• Chinese electromagnetic lock with affordable price and holding up to 280 kg. Inexpensive and fairly durable solution for the entrance.

• ML-295K also available in two colors gray and brown. Water protection is provided on basic level. The kit comes with a corner, convenient for installation on the entrance doors. The corner has small symmetrical shoulders. If they seem uncomfortable for a particular situation, order the bar, it is available as an option.

• Olevs M1-400. This castle has the richest choice of body colors. Large holding force up to 400 kg, comfortable installation angle. The only disadvantage for use in access and street doors– low level of moisture protection. Olavs M1-400 is not afraid of frost, like all locking devices of this type.
• OLEVS m2-400 differs from the previous model in the presence of a compartment with a terminal block with sufficient space for the ACS controller. This somewhat increases the price of the M2-400 electromagnetic lock, but makes the installation more convenient and reliable.
• For heavy doors, we can recommend an electromagnetic lock for 450 - 500 kg from one of the Russian manufacturers. For example, . Choose better device in a cast case. Almost all models with this holding force have a controller compartment. A large and strong corner is more reliable than an aluminum Chinese with a similar hold up to 500 kg.

During the repair, many people think about changing. The principle of its operation is based on installed lock. What if the magnetic lock is not working or you want to replace it? Installation is always possible with your own hands. This article will provide photos and reviews of home repairs.

What is a magnetic lock?

First you need to understand what a magnetic lock is. The basis of his work is magnets. There is a magnet inside the door. A metal plate covers it from above. When the door is opened, the handle moves the metal partition and the magnet. As a result, the door opens.
This type of lock is installed on interior doors. But you need to take into account the fact that such a door cannot be closed. Perhaps this is one drawback that castles of this plan may have.

By type, magnetic locks are divided into:

• passive (suitable for lockers);
• built-in (for interior doors);
• electromagnetic (for entrance doors).

What attracts in the installation of magnetic locks?

From the positive properties, consumers distinguish:

1. Silent operation - when the door is opened, there is no sound from the clicking tongue, which is contained in a conventional lock. Such a lock is convenient to install in a house where there are children. During sleep, no one will wake them up with an opening door.
2. Easy to install. When buying such a lock, you can install it yourself.
3. Absence of trauma. Even small researchers will not be able to do anything with a magnetic device. It does not have protruding parts, such as a retractable tongue that you can move and get your finger into the recess.
4. Durability. Magnets do not rust or wedge, as is usually the case with mortise locks.

As for the negatives:

1. The magnetic lock only fixes the door, but does not lock it. This means that you will not be able to “lock the lock” on the door.
2. Price. Magnetic locks are an order of magnitude more expensive than mortise locks with a tongue. But silence and reliability cost more.

Do-it-yourself magnetic lock installation

The magnetic lock is a novelty in the domestic market. But it is gaining more and more popularity. Of course, it is better to entrust the installation to specialists, but even without that, not the most budgetary lock, it is quite possible to install it yourself.

To install a magnetic lock you will need:

• Roulette;
• Drill;
• Screwdriver (screwdriver);
• Set of drills;
• Sander.

Advice. To make it easier to install the lock, remove the door from the hinges.

1. Mark with a pencil to determine where to drill through hole. Also determine the place for the niche of the magnetic lock;
2. Drill a hole through in the place where you plan to install the mechanism;
3. Drill a niche according to your markup. Later, a lock will be installed there;
4. Mark with dots the connector where the lock will connect to the door;
5. Drill holes for mounting bolts. Go deep enough to install the bolt;
6. Try on the first part of the lock and fix;
7. Next, install the second part with the magnetic mechanism;
8. Check the operation of the device.

If your mechanism does not work, disassemble the device, check if you have correctly bookmarked the magnetic part. If you have any questions, please refer to the instructions. There will be a detailed installation diagram.

Attention! A correctly mounted magnetic lock does not make noise when opening and closing the door. If your door makes a clicking sound, then the lock needs to be fixed.

In what cases is it necessary to repair a magnetic lock?

The magnetic design is a reliable thing, but even here there are some nuances. Possibly due to incorrect installation individual elements or some other factors, the magnetic structure began to function incorrectly. What should I pay attention to when repairing?

Please note that if the lock is noisy, it is installed incorrectly

• Fastening deformation;
• Loosening of the mounting angle;
• Incorrect fixation of the plate;
• Incorrect installation of the magnet;
• The lack of attraction;
• Door deformation.

These are the most common cases in which magnetic locks are repaired. In case of deformation of parts, as well as improper fastening, they should be replaced. But if the lock has lost its attractive property, then it is better to measure the door holding force. For interior doors, the force of attraction is up to 100 kg.

User reviews of magnetic locks

Sergey: “During the repair, a team of installers installed doors (we purchased them separately, like a canvas). At our request, magnetic locks were installed in the doors. They cost us 500 rubles more than usual. They work really silently. Only the door does not close, but we need one.”

Julia: “Now you can leave the baby’s room with a calm soul, the door does not rattle. Previously, our latch could wake the child. And what's good, the door opens both forward and backward! We are glad".

Valeria: “My husband installed the locks, he didn’t figure it out the first time, but then everything went as it should. Now the kitchen door opens with a slight pressure of the elbow (when the hands are busy).”

Sergei: “I installed the magnetic lock in an hour, but, however, the second time. I had to use the instructions. In fact, there is nothing complicated. The second door yielded better."

Magnetic door locks for interior doors

Magnetic locks are among the most modern systems for locking interior doors. They became popular thanks to a special mechanism. The convenience of their use lies in the fact that the metal tongue of the lock is easily attracted to the magnet, which is mounted in the door shell.

Operating principle

The presented type of lock has a simple principle of operation. It is based on magnetic fields that act in the opposite direction from themselves. In this case, different poles attract, and the same repel. This effect is sufficient for reliable fixation of the door in the closed position, and its simple opening.

Kinds

Today manufacturers door hardware produce many types of magnetic locks. They differ in how they work and internal device. in diversity model range It is worth highlighting the following types of devices that differ in the principle of operation:

• magnetic;
• passive;
• electromagnetic.

Magnetic lock for interior doors

The principle of operation of passive locks

A metal plate is installed on the door leaf, and a magnetic strip is attached to the slope. To open this lock, no mechanical components are used. Opening occurs when two elements are separated, for which you do not have to apply special efforts. This type of castle is the simplest. It is most often used on small and light door leaves, for example, in the so-called accordions. A passive lock does not provide security, as it only holds the door closed.

The principle of operation of a magnetic lock

This design is more complex than the previous one. It has not only magnetic, but also mechanical elements. To open it, use doorhandle, the rotation of which mechanically returns the tongue to the groove. As a result, the magnet opens. Sometimes doors go on sale already equipped with similar locking systems.

The principle of operation of an electromagnetic lock

Locks of this type can be used on both interior and exterior doors. It is often used in public buildings such as offices or banks. Involved in its operation electricity, when disconnected (with a special key), the lock opens. The presented locking systems are the most complex. Their design includes the following elements:

• strips with a high degree of magnetic permeability;
• electric magnet.

Electromagnetic lock

The installation of these locks is carried out in those premises that need high level protection. The device requires an electrical connection to operate. The electromagnetic system is the most reliable and expensive. The key to it is unrealistic to pick up because of the huge number of possible combinations.

In addition, magnetic lock systems differ from each other in the way of installation:

• invoices;
• semi-mortise;
• mortise.

Mortise and overhead types of systems usually have a special button, which is designed for emergency opening of doors during power outages. More modern models equipped additional system power supply, which is similar to a battery. It allows the lock to function for about 24 hours without connecting the centralized power supply. Mortise lock gained the most popularity among buyers

Advantages and disadvantages

The presented interior locks have become in demand due to such advantages:

• long service life due to a small number of moving parts;
• no traces of wiping due to the fact that the elements do not touch each other;
• in cases where the door has sagged or the canvas is slightly warped, the magnets continue to attract each other, and the lock closes;
• to close the door, no effort is required, just push it, as the magnet attracts the door leaf;
• when closing, there is no sound interference, such as clicks, which is a positive point in cases where these systems are installed on the doors of children's bedrooms or recreation rooms.

Magnetic systems have some drawbacks that you should be aware of when choosing fittings. For example, during intensive use, key moving elements wear out, after which the lock will have to be replaced with a new one.

Overview of the best models

findings

The advantages of magnetic locks make them more and more popular in the domestic market. These are practical mechanisms that stand out interesting design, various coloring and reliability. Conventional locking systems have lost their relevance against the background of silent and easy-to-use magnetic fittings.

Electromagnetic lock is an electronic locking device that works on the principle of radiation electromagnetic waves, aimed at a reciprocal metal plate (anchor) fixed to the door, to limit access to a room with high traffic.Keeping the door closed is ensured by the action of an electromagnet, which is supplied with voltage from 12 to 24 volts, with a current strength of 100 mA to 800 mA. An electromagnet attracts an armature, with the help of magnetic field, having overcome which only a jerk with a force of 50 to 1000 kg is able, depending on the type of magnet.

For remote control such a locking device, it is advisable to use a video intercom or radio relay, the first will allow not only to open the door from the video intercom monitor, but also to see and also talk with the visitor. Among access control systems, electromagnetic locks are the main type of electronic locking device.

According to requirements fire safety premises magnetic and others electronic locks installed at emergency exits fire doors only if it is possible to open them from the inside using a button, without a key (card or other identifier).

Electromagnetic locks door for indoor installation.

Full set includes:

• An electromagnet consisting of a core with a winding and a housing is installed on the door frame;
• Anchor - installed directly on the door leaf;
• Controller - installed in an accessible place, next to the door;
• Power supply - mounted near the controller
• Magnetic key signal reader (TM, card, key fob) - mounted next to the door, outside the protected area.
• The exit button, which opens the power supply circuit, is located from the inside, next to the door.

All presented magnetic locks on the site are sold complete with a mounting bracket, an anchor - a counter plate, and fasteners.

How does an electromagnetic lock work?

To hold the door closed, a voltage is applied to the lock electromagnet, which contributes to the creation of a strong magnetic field. The mating metal plate is attracted to the magnet, which ensures permanent closure until the voltage is relieved.

Power failure (by the controller or in emergency) also means the absence of a magnetic field. Voltage control is carried out by the controller, which, upon receiving a signal similar to the code stored in the device’s memory, turns off or turns on the current supply to the winding. Since the metal of the counter plate and the core is magnetized under the influence of a magnetic field, a reverse pulse is provided to remove the residual magnetization.

To open doors in normal mode cards are used or electronic keys, the signals of which correspond to the codes recorded in the controller's memory. To open doors with inside exit buttons are installed or a signal is supplied from the access control system.

What electromagnetic lock to choose for the door?

Types of electromagnetic locks.

1. Electromagnetic locks are divided according to the holding force:

• For wooden doors use electromagnetic locks with a force of 50 to 180 kg;
• For metal-plastic and metal doors use magnetic locks from 180 to 280 kg;
• For heavy metal doors, electromagnetic locks from 280 to 1000 kg are used.

2. Locks with an electromagnet can be installed not only on doors with external opening, but also with internal ones, using special corners purchased separately.

3. Electromagnets are different design features- work on the shift of the crossbar or on tearing off. Electric bolt locks are convenient for mounting inside the door leaf or door frame and also they are closed for access.

4. Electromagnetic locks are divided according to the method of fastening - overhead or mortise. The most common variant of overhead locks, since mortise magnets are not able to hold a large pull-off force.

The main advantages of locks with electromagnets.

In the presence of necessary tool and experience in installation, electromagnetic locks are quickly installed and do not require special monthly maintenance. Due to the absence of moving parts and, accordingly, friction, the locks are practically not subject to wear, which positively affects the service life of the device. The principle of operation of electromagnets involves the use of a minimum number of parts, therefore, as a rule, the price of models is not high.

You can buy an electromagnetic lock only in a specialized store of access control systems. The magnetic locks presented in our store are powered by 12 V.

Installation of an electromagnetic lock requires experience in locksmith work and knowledge of low-current systems.
