He doesn’t bark, doesn’t bite, and won’t let him into the house, even if he has a key. This is an electromagnetic lock, the control controller of which can be powered by mains or batteries and hold metal, plastic or wooden doors of any weight. This lock is installed on the entrance or interior doors in homes and offices. Its advantage is the possibility of remote opening by pressing a button or by presenting an electronic key to a reader. The advantages of such locks are the simplicity of design and installation, high reliability And low price.

What is an electromagnetic lock

Closing doors in high traffic areas can be a problem - the mechanical latch does not always work and does not signal the closing. An electric lock will save you from such problems, which is not only capable of reliably securing the lock, but also giving a sound or light signal. To open a door equipped with such a lock, you must use an electronic or coded key. A great convenience of such locks is the ability to connect them to an intercom.

Device

An electric lock is a locking mechanism based on the use of the magnetic properties of an anchor installed on the door, which holds a metal plate fixed to the door leaf. Opening occurs by short-term removal of the supply voltage, which is performed by a button, remote control, magnetic key or plastic code card. Controllers are used to control the open state time and indicate this position.

Principle of operation

Electrical operating principle magnetic lock is based on the use of magnetic induction - the effect of the appearance of magnetic properties in the core under the influence electric current. A coil with wound wire is placed on the core. When electric current is applied to the coil, it creates electromagnetic induction - this is a physical effect that induces (generates) magnetic properties in the core (armature). The anchor is fastened to the stationary part of the door, and the striker plate is fastened to its leaf.

Connecting an electromagnetic lock

Electrical diagram electromagnetic lock connection includes serial connection into the closed ring circuit of the power supply, disconnecting controller, and electromagnetic coil. The permanent operating state of the electric lock is the on mode, in which voltage is applied to the winding and the lock is closed. Circuit break controllers can be designed as:

• buttons indoors on or near the loot;
• opening buttons on the video intercom;
• a contactless controller that can be installed on both sides of the door and opens when a plastic magnetic card or a special key is brought to it;
• It is possible to install several circuit breakers connected in series.

Types of electromagnetic locks

There are two types of electric locks based on the type of locking – pull-off and sliding. According to the installation method, they are divided into mortise and overhead electromechanical locks. For glass doors, it is possible to use only overhead options, the designs of which provide for fastening to the glass. For wooden and metal doors it is possible to use all types of electric locks - overhead, mortise, sliding and retaining. Hinged doors will require the use of shear models with high holding force.

You can buy electromagnetic door locks in construction supermarkets in Moscow, St. Petersburg, and other Russian cities.

How to choose an electromagnetic lock

The choice of lock depends on several factors, including:

• type and weight of the door leaf - the type determines the possible restrictions on the use of mortise or overhead devices, and the weight determines the breaking force;
• the presence of a stable power supply - if there is a possibility of power failures, it is necessary to provide backup additional power in case of an emergency shutdown, and this requires locks with low current consumption;
• requirements for the locking controller and its indication - the lock must control the locking in order to include it in the system burglar alarm, protection against burglary is required;
• view necessary ways opening - when using several types of keys, buttons, remote controls or intercom systems, the lock must be able to work with all the options you need;
• weather conditions – installation of an electromagnetic lock outdoors requires the use of all-weather models with a wide range of plus and minus operating temperatures;
• requirements for limiting access to the premises - can be achieved by using modern digital access control controllers with restrictions on the period of their use during the day, keys of different access levels and other control methods.

Video

They usually include instructions with their products that show the connection diagram for the magnetic lock. Now such devices are very popular and are installed in entrances, offices, industrial enterprises, and private homes. The lock can be used with an intercom or even without it, which will reduce the cost of the circuit and simplify the connection of the lock.

Selecting an electromagnetic lock

To choose a suitable lock, you need to know the operating conditions of the device, take into account the safety and design requirements. Lock categories:

Locks are divided by holding force, the range is from 100 to 1000 kg. To open a lightweight door, you need to choose an option with a holding force of up to 150 kg. For severe metal door a reinforced model that can withstand up to a ton is suitable;

the body of the product must ensure the safety of the magnet, so it is better to choose nickel or galvanized models;

determine the operating temperature of the product, which is different for internal and external doors.

Magnetic locks are also divided into one-way opening and two-way opening devices:

Magnetic locks with one-way opening are used in enterprises where the constant presence of working personnel is required. In this case, the operator receiving the intercom call decides whether to let the visitor in. This circuit for connecting a magnetic lock is the most reliable; the lock and intercom are separate elements of this circuit.

The option with two-way opening is used if it is necessary to open the door with a magnetic key or contactless card. In this case, it is necessary to use a controller containing card or key codes in memory. Recently, it has been convenient to use a universal controller. It is placed in a sealed junction box near the door itself, the contact of the calling panel is connected to the exit button. The controller considers closing the contacts as pressing the open button. This magnetic lock wiring diagram requires professional installation skills, as incorrect connection may damage the lock system.

Connecting a magnetic lock

Installation of the mechanical part of the device is carried out like installing a conventional lock. Difficulties may arise when laying power wires and connecting to the control system. To install a magnetic lock you need:

study the installation and connection instructions;

install the mechanical part of the lock;

install a reader and an exit button.

The magnetic lock connection diagram provides for placing the reader closer to the lock, and the exit button on the door frame. Experts recommend carefully hiding the wires of the reading device.

study the procedure for connecting the lock to the controller;

lay the cable from the lock to the controller;

mount all the elements of the circuit; the power contacts must be connected last to avoid short circuit;

connect the mechanism to the power supply;

with the lock disconnected from the power supply, install the controller and connect the power again;

set up an electromagnetic lock.

When connecting magnetic locks, the following features should be taken into account:

the controller must be placed in a bag in advance to prevent moisture from getting on it;

after installing the lock, you need to check the condition of the plate and check the strength of the lock plates;

if the controller is designed as a separate device, you need to produce a master key for encoding user cards.

A magnetic lock is an easy way to make your home or office an impenetrable fortress. It can be installed on entrance doors, interior doors, and cabinet doors. The mechanisms can operate without repair for two hundred thousand cycles. If you want to install a mechanism at home, the magnetic lock connection diagram will help you complete the installation without errors, and if you do not have experience in performing such work, contact our organization.

Brings to your attention instructions for installing an electromagnetic lock. Now you can easily forget about simple locks. Electromagnetic locks are capable of creating a force of 350 kg. You just need to connect the electromagnetic lock.

Today, an electromagnetic lock can do a lot. You will need a low level of power wastage to operate it. His efforts will ensure reliable protection from thieves. In this article you will find information on how to install an electromagnetic lock with your own hands.

What is an electromagnetic lock?

Many people don’t know how an electromagnetic lock works? If you understand its design, then you can understand that the operating principle of an electromagnetic lock is simple. Inside there is a coil that is wound on a core. The belly of the electromagnetic lock is filled with compound. This is it internal organization electromagnetic lock. As you can see, there is nothing complicated in its design.

The holding force of the plate will depend on the following factors:

1. Contact area between core and plate.
2. Number of turns of wire.
3. Current.

The force of attraction in an electromagnetic lock will depend on the voltage. That is why the greater the tension, the greater the force of attraction of the lock. You also need to remember not to overload the lock high voltage. As a result, its coil will overheat. That is why if you have installed this device, you will need to match it.

Some electromagnetic locks can be repaired. They have no filler inside, so you can easily remove the coil. Thanks to the feed direct current the coil does not heat up. If your lock is generating heat, then this may be due to the following factors:

1. Magnetization reversal of steel.
2. Eddy currents.

Both phenomena can be easily eliminated with the help of special measures. If your electromagnetic lock overheats, then it is necessary to install varnish insulation. After a power outage, you have an oscillating circuit that generates alternating current. The direction of the field will change very quickly. As a result, the voltage will drop and the door will open.

Installing an electromagnetic lock with your own hands is a fairly simple process. Almost anyone can perform the installation. Before connecting an electromagnetic lock, you need to decide what type of operation it has. There are locks that work to close or open. To do this, you need to set the jumper switch correctly. In this case, the number of output terminals can increase to five:

• Two pins will be used to supply power to the device.
• Three contacts can serve as a switch. The general contact will always work. Others will depend on the state of the button.

According to these factors, you need to select a controller. Before connecting the electromagnetic lock, you need to find out:

1. Is there a limiting thyristor?
2. Is there a capacitance built inside to block magnetization?
3. What does the lock react to, and what type of control is available.

During connection, you need to connect the device to the intercom. The controller must have an input for unlocking the lock using one button. Usually the lock opening terminal is located in a dark room and therefore it must be backlit. The device must be applied protective covering. It will be able to provide:

• Varnish is a cheaper option. This layer will look thick and will not last long. As a result, the force of attraction may decrease.
• Zinc is a compromise option. The layer will not be very durable. The force of attraction may drop due to the gap that may be created.
• Nickel is considered the highest quality coating. It is beautiful and has no rust.

If the steel on your door has become rusty, then you should take steps to clean it. You need to take fine sandpaper and clean the door.

The main distinctive characteristics of an electromagnetic lock are ease of operation, high degree of protection, relatively easy installation and long service life. All these factors should be taken into account when choosing door locks.

Operating principle of an electromagnetic lock

The operating principle of this type of lock is very simple. Due to the force of attraction of an electric magnet to a metal plate, it is difficult to open a door with this type of lock without a special key.

The iron plate is attached to the door leaf, and the magnet is attached to the door. When electric current enters its winding, the necessary electromagnetic field is formed, which attracts the plate on the door leaf. When a special command is given that disables this field, the door opens. If you do not turn off the field, then, accordingly, the electromagnetic lock will continue to work, but the door will not open.

The electromagnetic background is removed by the access control and management system.

Types of electromagnetic locks

Even this type of lock has its own subtypes, namely: with magnetic keys, mortise and overhead. They may also differ in internal design.

The most popular are mortise locks, since thanks to them, the structure and fastenings can be hidden at the end of the door and the electromagnetic lock will not take up extra space.

The advantage of electromagnetic locks over others

The friction between the elements is minimal, which means the service life is quite long. Also, installing an electromagnetic lock and connecting it will be possible even for a non-professional. The equipment is not susceptible to corrosion and freezing, because the mount is located in the doorway.

Attaching an electromagnetic lock to a door is quite quick and easy. But if you are unsure of your abilities, then it is better to entrust this matter to knowledgeable person, as there is a risk of damaging the door.

Disadvantages of locks

The only, but at the same time, significant drawback is the inability to work without electrical power. So if you don't have an additional power source that can kick in in a split second after a power outage, then all the benefits come to naught. If there is such a threat that the electromagnetic lock may lose power, then it is recommended to install it together with a mechanical or electromechanical lock.

Where are these locks installed?

Most often, electromagnetic locks are installed in offices and organizations, as well as on entrance doors apartment buildings. It is worth considering that they cannot be installed on emergency exit doors.

Other types of electronic locks

All electronic locks are inherently the most reliable and durable. An electromagnetic lock is just one of many. It is the simplest in its design and operation. But, as already said, it has significant shortcomings, which can be decisive when choosing this castle as a home one.

Many people prefer electromechanical devices, the system of which uses levers and a key cylinder. By appearance they resemble classic, familiar mechanical locks. However, they contain an electromagnet small sizes, which makes the whole system work. From the outside you can open the door with a key, and inside you will only need to press a button, which is very convenient for apartment buildings and intercoms.

Electromotor locks are similar in principle to electromechanical locks. The difference is that the levers are driven by a small electric motor. The system has a “soft opening” principle, which extends the service life of the lock.

Installation and connection

You can connect the electromagnetic lock yourself. The connection diagram is presented on many sites on the Internet. You can also find similar information on the official websites of manufacturers or contact them for advice.

When installing an electric lock, take into account its dimensions and weight, as well as in which direction the door will open. The passage of the doorway is very important. If the door is expected to be opened and closed frequently, then an electromagnetic door lock is recommended due to its durability. But if there is even the slightest doubt about the uninterrupted electricity, which is necessary for the normal operation of such a lock, then it is better to give preference to an electromechanical lock, which, if something happens, can be opened with a regular key.

How to install an electromagnetic lock with your own hands

If you don’t have enough money, but have enough free time, then you can install an electromagnetic lock with your own hands. You will need:

• Electromagnetic lock.
• Copper wire with six branches with a cross-section of half a square millimeter.
• Network version for intercom and controller.
• Backup or uninterruptible power supply.
• Copper power wire with a cross section of 0.75 and 0.5 square mm.
• Panel with call button.
• Key and reader for this key.
• Video intercom.

On the entrance doors or gates, install a call panel, a key reader and an electromagnetic lock itself. The connection diagram is as follows: turn on the power to the lock, and place the controller in a water-repellent case. The power source must be installed in the room together with the video intercom. Now you need to connect everything with wires for the circuit to work. Wire from the call panel to the video intercom. You also connect one line to the power supply, controller and intercom. The power of the last two lines should be twelve volts.

As you can see, the electromagnetic lock circuit is very simple. But if you have not previously installed and connected such things, then it is better to ask for help or advice from a professional. If you buy a lock in a specialized store, they will certainly offer you assistance in installation and connection. In addition, there you will receive a guarantee, and if something happens, you can demand monetary compensation.

Installing an electromagnetic lock on a door

If you are planning to install an electromagnetic lock on wooden door, then you may be faced with the question of how to properly cut a door for a lock. to install mortise lock yourself, you will need:

• A simple pencil.
• Drill.
• Hammer.
• File.
• Screwdriver.

To begin, determine at what height from the floor the lock will be located. Typically this height is one meter.

Place the lock on the door and trace it with a pencil. It must be applied to the end. Now, choose a drill bit that matches the thickness of the lock. If you don’t have one, you can use a drill that is slightly smaller than the lock. Mark the permissible drilling distance on it.

Drill to the bottom mark. The resulting hole needs to be “brought to mind.” Trim its walls so that it is smooth and fits well with the lock. From time to time, try on the lock and cut out the excess with a file.

When the lock goes all the way, you can outline with a pencil where to cut out the front cover. You may find it more convenient to select the desired location with an extended lock. It can be attached to the door, opposite the already cut hole. Drill the necessary new holes.

Insert the lock and secure it with screws. Check how the whole structure works. Close the door and turn the key, do it with force so that marks remain on the door frame.

Drill holes along the marks and align the walls in the same way as you did before. Prepare a recess for the strip and connect the electromagnetic lock to the network. The device is completely ready.

It often happens that if the client installs the lock himself, and during the connection some malfunction is discovered, then the warranty does not apply, that is, the money is not returned. Therefore, be extremely careful and attentive. Measure everything several times, consult with your family and friends. Try on the lock after each cut. After all, if you remove what was not necessary, the lock will simply fall out or move too much in the door, as a result of which the screws with which it is secured will not hold it, but, on the contrary, will spoil the door and grind down the holes even more.

It is also recommended to install a lock on removed door, to make it easier to drill the recess. After all, the drill must be held strictly perpendicular to the door, not move or tilt to the sides. Don’t expect to be able to cut everything out neatly without making preliminary notes; most often, this is a rash opinion.

The article contains diagrams for connecting an electromagnetic lock to various equipment.

• Electromagnet, Z-5R, Matrix-2
• Electromagnet, Matrix-2K
• Electromagnet code panel

Diagram for connecting a magnetic lock to z-5r and matrix-II

I would like to draw your attention to the fact that you need to install a shunt diode on the electric lock. It will remove voltage surges that occur in the lock, especially when the voltage is removed from it.

The jumper on the controller is in its normal position. The power supply can also be used with lower current consumption.

Connection diagram of matrix-IIK to an electromagnetic lock.

Diagram for connecting an electromagnetic lock to a reader combined with a controller. Well, I wrote about the diode above. It's really worth installing. In both cases, the wire from the power supply to the controller and from the controller to the lock must be type ShVVP-2x0.75.

Connecting a keypad to an electromagnetic lock.

Code dial panels usually have a relay output. With three contacts

• COM - common connects to the negative of the power supply.
  
• NC - Contact for connecting electromagnetic locks. BUT.
• NO - Contact for connecting electromechanical locks. NZ.

Fine open lock connects to a normally closed contact. ■

The main thing is that when connecting to a code panel, you should always install a bypass diode. It must be installed on an electromagnetic lock. Some Chinese aluminum locks already sometimes have surge filters installed. And installing a bypass diode is optional.

It is better to look at the connection diagram for a specific code panel in the instructions from the panel. If you still need a wiring diagram for the code panel, please leave a review about it.

Electromagnet button power supply.

You can simply connect an electromagnetic lock to the power supply. But you need to understand that the ability to open the door with outside will not be. To connect you can use regular switch Sveta. Turned the door on and closed. Turned off the door opened. But in practice, you should not use such a connection scheme. You will have to remove the tension and reapply it.

This scheme is usually used at checkpoints. When the decision to let in or not is made by the guard, and not the only door to the room is closed. In these cases, it is more convenient to use a lock control unit; I would even say the Z-396T opening timer. Simple scheme connection and setting the opening time gives advantages over the Z-5R controller. An external reader cannot be connected to the timer. But you can connect a door open button. When pressed, the door will open for a specified time.

And information on how to configure the controller has been collected in a separate article. If you have any questions, leave comments.
