Best electromagnetic locks for 2020

When a person renovates an apartment or builds his own house from scratch, the issue of safety is in the forefront. After all, you can build anything you want, but to what extent such a structure will be protected. Often people have guard dogs, but even they are not able to secure the site. The correct door lock will guarantee the reliability and safety of all things, but it is important to pay special attention to its choice so that the purchase does not turn against its own owner. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best electromagnetic locks for 2020.

Varieties and principle of work

Electromagnetic locks are versatile devices that can be used in almost any conditions. But it is important to understand that not all models are designed for outdoor use, some cannot withstand low temperatures. The first thing to know is that locks differ in the way they are installed. So, models are sold:

• Built-in. In this version, the mechanism body is located inside the door leaf. The main advantage of this option is that the device is not visible, so it will not stand out against the background of the overall interior.
• Semi-cut. In this case, the structure protrudes slightly to the surface, but does not strike the eye.
• Overhead. Here the entire system is mounted on the door and is not hidden. The advantage of this option is the easy installation method. However, such a solution does not always contribute to an attractive appearance.

Also, magnetic devices differ in the principle of operation. But there is nothing complicated here, since only two types are known:

• Passive;
• Electromagnetic.

The first option assumes working with standard magnets, this comes out of the main drawback - poor door retention. This option is suitable for installation in interior doors and no more, since in order for the structure to open, it is enough to pull it by the handle. Of course, you can only dream of safety in these models. But for general use, this is a great option that has a low price and attractive appearance.

Advantages of a passive mechanism:

• Low cost;
• Easy installation;
• Durable as there are few parts.

Disadvantages:

• For partitions and interior doors only.

An electromagnetic lock is the perfect option, its work is carried out from the network, so you will not be able to open the door on your own. The design is a ferromagnet, which is made in a special metal winding where an electric current moves. Thanks to its action, a great force is created that tightly fixes the door. This design is capable of withstanding loads of up to 1000 kg, which makes it impossible to open this door with the help of improvised means.

Advantages of an electromagnetic lock:

• Great magnetic strength;
• The door can withstand high loads;
• Low installation and product costs.

Disadvantages:

• If the structure is external, then the effect of the magnet can be easily reduced. Some people put on transparent stickers that prevented the magnet from sticking tightly, making it easy to open the door.
• Needs constant food.

Also, before buying, it is important to know the structure of the main types of locks.The principle of operation of a magnet is known to man both theoretically and practically, he has repeatedly observed its action, so there is no point in going into complex physical concepts. Moreover, doors that operate on an ordinary magnet are rare, few people install such locks, since they do not see much benefit from them.

However, besides the usual element, there is a hybrid of mechanical and magnetic construction. In this variant, the core is placed inside the groove using standard crossbars. The door is held more tightly due to the fact that two forces act on it at once. However, this option was not widespread and rather a rarity than the usual routine.

The only reliable product is electromagnetic locks, due to the complex principle of operation, where they are constantly exposed to an electric current, it is almost impossible to open such a door without a special key. It is tightly held without leaving even a gap. People often come across such a lock when entering an entrance and know its main disadvantages. However, in addition to residential use, it is often used in warehouses, industrial premises, and sometimes even in offices.

What is included?

For the right choice, it is important to pay attention not only to the technical characteristics, but also to the items that are included in the kit. In addition to standard products, along with the lock, additional devices may be found that will help increase the holding force or make operation easier.

Often the following products are included in the kit, they can be found in 90% of cases:

• An electromagnet with a capacity of 100 or more kilograms;
• A special plate that is installed on the inside of the door;
• Special cables and connections to easily connect the equipment to the electrical network;
• Fasteners;
• Assembly and installation instructions.

Regardless of the model, the minimum holding force is always 100 kg. If a device with a lower number is found, then it is not recommended to buy it, since it is easy to open it. If a person is worried about his property, he can install a door that can withstand a ton. It will be impossible to open this option. Locks that can withstand a load of up to 300 kg are in great demand. Such force can only be used with the help of a dozen men or a vehicle. One person cannot cope with this.

The lock is controlled by a special keypad that closes the entire system and opens the door only after presenting an electronic key or card. Some people install such doors in a country house, while they hide a digital panel, which will leave an unaware person at a loss. There is no keyhole, there is a handle, and the structure does not move even after several power attacks. Installing an electromagnetic lock will give the user a guarantee of security.

What are the accessories included?

Often in the kit, more often from branded firms, there are several auxiliary devices that simplify operation and provide reliability. If it turns out that some auxiliary product or element is not there, then the owner will have to buy it separately. List of additional devices:

• Uninterruptible Power Supply (UPS). This is a useful piece of equipment that will provide a continuous supply of current, even when the power is off. There are built-in rechargeable batteries inside the UPS, which are able to keep the lock functioning for several hours or minutes (depending on the model). The UPS kit includes a charger. It is connected to the nearest outlet and is in this position constantly.
• The controller is a universal device designed to create auxiliary systems in the castle. So, if a person wants to install a digital panel or a key card reader, then he will need this equipment. The disadvantage of this device is that it is rarely found in the package, as manufacturers prefer to sell it separately in order to get more value.
• Closer.The main purpose of this element is convenience. In addition, it extends the service life of the entrance lock. It is rarely used when placing an electromagnetic structure in a country house, but in places with high traffic it is a useful tool, thanks to it, the main elements will remain intact and last longer.
• Intercom. Without this element, most people cannot imagine a full-fledged magnetic lock. The product is useful in that it allows you to recognize the visitor. This will provide the person with more security. Country house owners install video intercoms so they can track passers-by who are interested in their home. However, intercoms have gained great popularity in public places.

Installation method

Installation of a magnetic lock does not require special knowledge and skills. This is a simple device that will take a minimum of time. For work, a person will need a screwdriver and instructions that describe the installation process in detail. There are also pictures that will make the task easier. Magnetic locks are not suitable for front door installations.

For the installation of electromagnetic equipment, the help of a specialist will be required, since an inexperienced user will not be able to correctly install the entire system or will spend several days on it. According to the installation method, there are two types of models: overhead and with a shift mechanism. The latter option works in conjunction with a mechanical lock and an electric magnet. As soon as the door is closed, several magnets fill the grooves that are located at the top and bottom. This design is safer than the first, where the fastening element is placed on the surface and there is access to it, at least from the inside.

Installation of the overhead mechanism.

The system is installed at the top, where the closer is located. This is the classic installation method. Due to this arrangement, the space at the top becomes smaller, which can cause resentment in tall people. Installation is carried out in several stages:

• First, a stencil of the mounting plate is attached, according to which a person analyzes the location of the bolt holes;
• The fixing plate is screwed into place;
• Experts mark the place where the electromagnet will be installed;
• Mounting the magnet in the appropriate holes;
• Wires are laid on the panel and buttons;
• Insulating cables;
• Performance testing and installation of auxiliary equipment.

Mortise lock

This option is more energy intensive than the previous one. During its installation, it is important to take into account the main nuances. If a person comes across the assembly of such equipment for the first time, then it is better to pay the master than to dismantle the device several times. For correct installation, follow the rules:

• The door is removed from the hinges - this is an important point, since the accuracy of the installation depends on it.
• Carrying out the markup, which is indicated on the diagram. It is better to carry out everything according to a special stencil in order to exclude possible mistakes. Indeed, even professionals with 10 years of experience sometimes resort to his help.
• Drilling holes for the magnet and marking the joints with the door frame.
• Installing bolts in the jamb, it is important to be accurate, because due to one mistake the whole system will not work.
• Installation of an electric magnet in the opening.
• Installation of the door structure.
• Connection and testing.

Before installation, it is advisable to check the operating condition of the system, as there may be cases of factory defects. So, when it is found, the person will not waste time.
