Electronic gate lock: types of electric locks and electric strikes

How does a magnetic lock work? Its closest “relative” and competitor is the electromechanical lock, which is a combination of electrical and mechanical parts. In an electromagnetic locking device, the acting force is a powerful magnetic field. The lock body with an electromagnet is mounted on the stationary part of the door, and an iron bar (anchor) is attached to the door itself.

Based on the type of action, electromagnetic locks are divided into pull-out and sliding locks; the method of fastening the device also depends on this. In the first case, when the door opens outward (it needs to be pulled towards you), rim locks are used, and in the second case, mortise locks are used. The door then opens inward. Users are usually interested in the question of strength - how powerful magnetic locks actually are, and how to take into account the pullout force when choosing a model. For interior doors, a lock that holds a weight of 120 kg is sufficient, but for metal doors you need to choose a product from among models with a tearing force of over 300 kg.

The obvious advantages of electromagnetic devices include their versatility: they can be installed not only on metal doors, but also on wooden or interior doors, on an entrance gate or gate. Therefore, the range of use of these locks has expanded noticeably: they are equipped not only with large offices or enterprises, but also with the entrances of residential buildings, and, increasingly, with private properties.

Installing an electromagnetic lock on a metal door

What is needed to install an electromagnetic lock on a metal door? A complete lock set includes the device itself with a strike plate, a power supply with a battery, a controller through which all elements are connected, an information reader, wires, an opening button, keys - including a master key, with which you can open a locked lock or recode his. Additionally, the door can be equipped with a closer for smooth closing, an audio or video intercom communication system.

Thus, the price of installing an electromagnetic lock depends on the configuration of the model, the type of door (interior or entrance, outdoor installation), and additional work on installing intercom communication. Our service for installing and replacing locks carries out quick and correct installation of the device, and is also always ready to advise you free of charge on the correct selection of an electromagnetic lock.

Install and connect

Since EMZ are not much different from mechanical models, their installation on the gate is also similar.

Fix the attached EMZ on the surface with the bolts that are included with the mechanism. Before installation, it is important to take measurements and mark the canvas. To do this, you need to attach the lock to the gate and trace its outline. Then drill holes for the bolts and release mechanisms.

Now you can screw the lock. To understand where the strike plate will be located, close it (pull out the bolt). Secure the bar at this point.

Installing a mortise EMZ is similar to the procedure described above, only you need to accurately calculate everything and select a place on the gate to install the lock. Before installation, check the measurements carefully so as not to damage the gate. After completing the installation work, make sure that the gate locks/unlocks well.

If the installation was successful, it's time to start connecting. Initially, additional components are connected (if necessary):

• readers;
• controllers;
• opening buttons;
• power supply.

To facilitate installation, each manufacturer includes instructions with their products, which should describe in detail how to connect to what.

The standard circuit looks like this: an EMZ with a reader and a controller is connected to a power supply, which is already connected to electricity and the control panel. If you have an intercom, then in order to be able to control the EMI, it must be connected to the appropriate interface.

Important! Make sure each wire is connected correctly. Don't forget about isolation. Check that the cables do not come into contact with wet surfaces and are not pinched. Do a test run of your work.

Bottom line

Now you know all the features of EMR for external use. We hope our article will help you choose a reliable lock for your gate.

General information

Electric locks have many advantages that are unique to them due to their reliable system, as well as their operating principle. Today there are a large number of designs of various configurations.

Design Features

The operating principle of electric locks is quite simple. The locking mechanism of the lock is played by latches in the form of pins, which when closed are pressed tightly by springs into a groove located on the opposite side, thereby locking the gate or wicket.

Electromagnetic type of lock

During opening, when the remote control button is pressed, a plastic key is applied and the stationary button is pressed. Or it is a combination lock, in which the system pulls back the locking pins, compressing the springs. The shutter is located at a certain angle, so the gate can close automatically.

The most effective system is one that has several modes. The night mode ensures reliable closing of the gate, while the day mode allows you to control the gate without leaving your home. These systems are used for garage doors, entrance gates and doors.

On the gate

Equipment

Often, an electric lock is sold at the same time as a video intercom. It is built into the design. This is quite convenient and allows you to save on purchasing an intercom and a lock separately.

At the same time, there is a saving on installation, since by performing the installation only once, you can get two devices at the same time.

Advantages and disadvantages

A design that combines mechanical reliability and electronic convenience has many advantages.

The main advantages of an electric lock:

1. Difficulty of hacking. Many models of electric locks do not have a key hole. Accordingly, an attacker will not be able to determine what type this design belongs to.
2. The device does not jam. Opening and closing the electric lock is very easy.
3. Long operating time. Unlike mechanical analogues, the service life of an electric lock is 2 times longer.
4. Quiet operation.
5. The design and installation of an electric lock can be combined with different security systems.
6. Possibility of remote opening of the lock.
7. Can be installed on any door leaf (corrugated sheet, wood, metal).

Option from the store

Flaws:

• For normal operation, a constant supply of electricity is required;
• An electric lock for a gate is more difficult to install, unlike a mechanical one;
• In many lock models, the bolt is located on the outside, which can accidentally get caught;
• It is advisable to cover the street lock with a visor, otherwise low temperatures and precipitation will cause malfunctions;
• The price of an electric lock is higher than a mechanical one. To this cost you need to add the constant consumption of electricity.

Types of electromechanical locks

A gate with an electromechanical lock allows various methods of installing a locking box. The most common options will be presented below.

Mortise

A groove is made in the gate body where the locking mechanism is placed. A groove is also made in the main part of the fence or in the load-bearing support-impeller, where the end of the gate adjoins.

Installation requires a thick slab gate. Most often, a wooden texture is used for installation, which allows you to make a neat recess and sand it before installing the device.

Important!

The design is used in almost all wooden gates and very often in the entrance doors of private houses. You can also embed the bolt into the bumper part.

Invoices

The box with the mechanism has special ebbs for fastening to the surface of the gate. This allows them to be used for any design of entrance doors and gates.

Special eyes are made for the tongue.

Outdoor (frost-resistant)

Their design implies a more complex structure of the case - the box in which all the mechanisms and structural elements are located.

Optional equipment

For stable operation of magnetic locks, it is recommended to install a door closer. This affordable device automatically closes the door at a preset speed and closing force. Another advantage of the closer is the extension of the service life of the lock due to the smooth and accurate closing of the door.

Since the magnetic lock requires a continuous supply of electricity to operate, it is a good idea to install an uninterruptible power supply. Autonomous batteries will allow the lock to operate normally for quite a long time.

Principle of operation

The mechanism works thanks to an erection bolt in contact with a spiral spring. To keep the gate closed, the bolt needs to fit into the counter part. If the mechanism is equipped with a solenoid, the tension will cause the spring retainer to reset. When the bolt enters the lock, the gate can be opened. If you close it, the mechanism will slam shut.

Most often, to open an EZ you need to press a button. To make using the mechanism more convenient, many owners equip it with a remote control system. This allows you to open the gate and activate the mechanism with a signal from the control panel. This function is especially convenient for car owners: in order not to constantly leave the car, you just need to press the remote control button so that the gate begins to open.

According to the principle of operation of EMZ, there are:

• motor. This model is equipped with a miniature electric motor. Some EMZ have several crossbars. For example, during the day you can use one, and at night two or more crossbars. This feature makes the model very safe;
• with electric latch. After unlocking the latch, the mechanism is activated under the influence of voltage;
• solenoid. In order for the crossbar to start moving, it must be exposed to a magnetic field. Otherwise the gate will not open;
• electrically blocking. The lock starts working under the influence of a magnetic card or a special key.

Review of manufacturers

Today, electronic locks are made by many manufacturers. Among this large number, we can highlight several proven manufacturing plants that are distinguished by the high quality of their products.

CISA

The most popular manufacturer of various designs of locks for electric gates is the CISA company. Locking devices from this company do not require constant power supply. They only need an impulse to open or close the gate.

Option for a gate at the dacha

The equipment for any model is standard. The electrical system must be purchased separately. The CISA electric lock can be purchased on the Avito website.

The selection of products is quite large, and the devices are not very expensive (for example, the invoice model 1A731.00.0 costs from 7,200 rubles). A special feature is that during a power outage, all devices can be opened mechanically.

Intercom

Mingyang

The manufacturing plant has focused on increased performance and comfort during operation of its products. Most often, products are represented by electric locks with remote controls, as well as stationary intercoms.

Falcon Eye

Any type of electric locks from this manufacturer is compatible with various intercom systems, video cameras and alarms. Strength: from 500 kg. Temperature range: from −40 to +50 degrees.

Falcon eye

Niedzwiedz lock

The JoyLock is used for vehicles with an electronic transmission. It is an electric lock with a joystick. The lock is made of steel 4 mm thick.

The design contains an anti-vandal lock DORMAKABA (German production).

The uniqueness is that professional installation is not required. You can install the entire lock structure yourself.

Latch on the gate

"Sheriff"

These locks are used as security in safes and self-service terminals. Very reliable, they have the most advanced anti-hacking system.

Description and comparison table

Features of choice

First, you need to pay attention to the location of the housing, since it can be made for right- and left-sided gate leaves.

The main emphasis should be on the following points:

• level of reliability (for example, 2 rods can withstand much more mechanical load);
• compatibility with the entrance structure, since not all wickets or gates fit a certain leaf pattern;
• the electric lock can be connected both with and without an intercom;
• required functionality;
• different manufacturers may supply a battery for autonomous operation;
• possibility of opening mechanically;
• type of key for opening: electronic lock or remote control;
• locking mechanism: lever or cylinder.

Electromechanical latch

Types of electromechanical locks

Having almost the same principle of operation, the bolts differ in their design and design of the locking mechanism.

Electromagnetic locks with controller

This is a simple latch that is electrically operated. But in addition, it is equipped with a special device - a controller, mounted inside the living space, usually in the corridor.

This device contains on and off relays in a plastic case, which transmit a signal to two indicator lights outside - red (closed) and green (open). This allows you to monitor the condition of the gate.

Electric latch

Under the influence of an electromagnetic field, the latch remains in the closed position. As soon as the lock, which neutralizes the magnetic field, is brought to the special magnetic slot, the latch is retracted into the lock body.

Electrical lock

The lock is constantly supplied with electricity, creating a magnetic field around the contact magnet. It is mutually attracted to the response magnet. As soon as the key removes the magnetic field, interrupting the supply of electricity, the magnets lose their ability to attract - the gate can be opened.

Motor block

Electromechanical street lock for a gate with a special counter part in which a moving contact is mounted. The movement of the tongue towards the motor is done manually; it enters the motor, where it is blocked by a magnetic field. The key operates the motor and the gate opens.

Solenoid interlock

A solenoid is an inductor that creates a magnetic field. It is mounted in the lock mechanism and maintains the movement of the latch.

Advantages and disadvantages of electromechanical locks

The main advantages of such locks include:

• High reliability.
• Convenience.
• If the lock is equipped with a code panel, then this completely eliminates situations where it is impossible to open the gate due to a lost key.
• A wide range of additions that make the process of opening/closing the gate more technologically advanced.
• Various structural and design options.

Despite their high reliability, these locks can still fail. The disadvantage is the high cost of such devices and expensive repairs.

What to look for when choosing

When choosing a magnetic lock, you should start from the type of door. So, for lightweight wooden or plastic sheets, compact locking devices with low power are suitable. The force to pull off such locks should be in the range of 150-200 kg. For metal entrance doors, more powerful devices are recommended that can withstand a load of 300 kg or more. For glass doors, there are sliding-type magnetic lock models that help avoid unwanted damage.

For swing doors, it is recommended to choose a lock with a door leaf position sensor. This will allow the lock to “understand” that the door is in the desired position and can be locked. Ordinary swing doors do not need such sensors, since they are equipped with an automatic closer.

When purchasing a magnetic lock, you also need to take into account a number of factors that affect the cost, such as:

• design features of the door;
• integration with the access control and management system (ACS);
• climatic conditions;
• features of the point of passage for visitors;
• fire safety requirements.
