DIY electromechanical locks repair

In detail: DIY repair of electromechanical locks from a real master for the site my.housecope.com.

The century of technological progress and the latest technologies has offered mankind many new innovative ideas regarding the protection of their property.

Locks are one of the means to protect yourself and your property. So, the main achievement in the field of security can be considered electromagnetic locks.

The advantages of these locks are obvious:

high level of security,
relatively low price,
easy to operate in any climatic conditions,
easily mounted on objects,
long service life.

Among the whole range of locks, there are electromagnetic ones, the most reliable, they need repairs and replacements of worn-out parts less often than others.

But, nothing is eternal ... These locks also break.

So, most of the sales of electromagnet-based locks on the market have a low level of maintainability.

A relatively simple design has certain disadvantages:

the magnetic block consists of a coil with an epoxy-filled core.

The "weakest" point of these locks is the coil; if it fails, you will have to change the entire magnetic block.

Note that its price is almost half of the total cost.

The change in the manufacturing technology of the magnetic block - the introduction of coil winding on the frame - increased the maintainability of this type of locks and made it possible to independently engage in the process of their repair.

The advantage is cost and time savings.

What is the independent repair of an electromagnetic lock. What problems do the castle face?

Usually they are associated with the disappearance of the holding force or the appearance of its residual magnetization.

Video (click to play).

Most likely, the loss of the holding force is caused by damage to the lock coil, associated with an open or short circuit.

Also, the reason may be:

malfunction of the lock controller,
power supply
or damaged connecting wires.

We check the serviceability of the coil with a tester, its resistance should be equal to several tens of Ohms.

If the resistance value does not correspond to the specified range, it is necessary to replace the coil, in the case of a collapsible magnetic block, or the entire block (if it is monolithic).

It is also easy to correct the appearance of residual magnetization on your own.

This malfunction occurs due to the failure of the capacitor, which ensures the appearance of damped oscillations in the coil.

To eliminate the defect, it is necessary to connect a non-polar capacitor parallel to the terminals of the electromagnetic lock, the capacity of which will be 220 - 1000 μF at 25 V.

In locks of domestic production, capacitors with a capacity of 220 μF are installed, for locks of foreign manufacturers we select the value of the capacitance experimentally.

As for the breakage of the coil, then such a malfunction cannot be eliminated on your own, you need to contact a specialist.

Timely repair of the lock will help extend its service life and protect you from many troubles in the future. Since the locks known under the Cisa brand do not only have excellent characteristics, they are fully consistent with them.

Before proceeding to the description of the repair of electronic locking mechanisms, we will consider their features.Unlike conventional models, the principle of which every student knows, electronic ones are distinguished by an increased level of protection and additional capabilities.

If the entrance door to the room is equipped with a simple mechanical lock, then you will need a key to get inside. If the door is equipped not with a mechanical, but with an electronic device, then the task is more complicated.

Front door electronic device - installation location

This is due to the fact that this type does not need a key, but a special signal that gives it a command to open or close. The signal itself can be received in various ways.

Some of the types of electronic products receive signals from sensors that are located indoors. Others require special magnetic cards. In the most modern types of devices, personal biometric data of a person are required to receive a signal to open or close a door.

On the one hand, it seems, why such difficulties, if you can use a mechanical lock, to open which you need a regular key. But not everything is so simple. If you need to protect yourself or your home, then you will not find anything more reliable than an electronic mechanism.

While it may not take long for crackers to open a mechanical device, they will have to work hard to open an electronic version. And their reliability is such that even experienced burglars are left in the dark.

Electronic mechanism with card

Modern technology has gone further. In some penitentiary institutions, doors with electronic locks are equipped with remote access, allowing them to be opened and closed from a distance. It is enough to look at the camera installed in the room and make sure that the person you need is standing in front of the door, and then give the signal for the door to open.

But no matter what device this electronic lock is equipped with for receiving a signal, special attention is paid to locking devices. Thus, the actuator can be either electromechanical or electromagnetic.

As you already understood from the above material, there are two types of locks - electromagnetic or electromechanical.

Electronic electromechanical door system

The role in this device has a "key". In this case, it means that, when interacting with an electromechanical lock, you will receive the opening / closing signal you need.

The key can even be an ordinary card, which must be applied to a special reading panel. In modern realities, a smartphone is used instead of a card.

If we are talking about a biometric lock, then you have to put your hand or finger on it. Some modern specimens even require a scan of the retina. In this case, the principle of operation is based on the fact that every person living on earth has his own biometric parameters, which cannot be faked.

Simple examples of electronic locks are equipped with a regular dial. In them, the signal is generated only after you enter the correct set of characters that only you yourself know.

As for the installation, they are installed on doors and safes.

These devices are considered reliable and practical for installation on a front door, garage or safe.

To open this device, you must pass digital identification. This approach will allow you to secure this lock from possible burglary, since all mechanisms will be blocked by electronics until the person passes the identification of the person.

Identity is identified using a special key fob or card, which is brought to the installed sensor. After the computer calculates that there is a person in front of it with the appropriate access level, you open the mechanism using a regular key.

This two-factor protection has proven itself well and continues to gain popularity.

How to use an electromechanical lock

Moreover, both the mechanical and electronic parts are protected from hacking. If the mechanics do not work without the permission of the electronics, then the electronic part itself is protected from the selection of combinations. At the same time, you set the number of rebounds yourself, as well as the time allotted for the set. There can be about a hundred attempts in total, or much more. Moreover, the set of combinations itself reaches one million.

If you wish, you can change the combination of numbers at any time. This approach is relevant if you live in a crowded place, and someone might accidentally notice how you are typing the code.

Mechanisms like these are also good and reliable. The principle of operation is based on the interaction of an electromagnet and steel plates. After the lock is in the closed position, voltage is applied to it. It is impossible to open it in this state with the help of lockpicks if you do not have special magnetic or electronic keys that turn off the power on the lock after identification of the person.

Controlling an electronic device from a mobile phone

This type of locks is the best suited for use in extreme conditions, when the mechanisms are exposed to negative temperatures or an aggressive environment.

Another interesting feature is that this lock does not have a keyhole. Therefore, its location behind the door cannot be determined visually.

Timely repairs to the built-in hardware of a door or safe is important for a number of reasons. If you notice signs of failure of the electronic lock, immediately contact a specialist for help.

A preliminary assessment and correction of breakdowns will save you from the fact that the lock will finally break at the wrong moment, and without regular preventive maintenance, equipment will fail and require replacement.

Repair of an electromagnetic lock

As for the symptoms of a malfunction, they are obvious. An error occurred while displaying errors on the display of the electronic device.

Leveler wear may occur. In this case, the mechanics will not work properly, and the lock will fail. The ambient temperature also affects the failure of the mechanism. In severe frosts, a failure occurs in the electronics.

If you want to avoid such a fate, but at the same time yourself do not have sufficient knowledge of how to repair this type of mechanisms, then you cannot do without the help of specialists. They quickly arrive at the call site and start fixing the problem. It takes an experienced technician about an hour to find the cause of the malfunction and fix it.

Remember that the repair of locks on a door or safe should be trusted only by professionals, since otherwise the master can only break a broken lock.

Finally, I would like to remind you that electronic types of locks are more expensive than ordinary locks, but unlike them, they are able to guarantee your safety.

The installation of the mechanical part of an electromagnetic or electromechanical lock is performed in the same way as the installation of a conventional locking device. Laying the supply wires and connecting them to the control system is the most difficult to work with.

Installed electromechanical lock, ready for connection

The owner of the electromagnetic lock, who decides to install and connect on his own, must begin work with a careful study of the instructions and the wiring diagram. If the main mechanism is already installed, you need to install auxiliary devices: a code reader and an exit button. For work you will need:

electric drill;
self-tapping screws for wood or metal;
pencil;
screwdriver.

It is advisable to place the reader as close to the lock as possible, and the exit button on the door frame.

For further work, you will need a two-core cable with a cross section of 0.5 mm. It is advisable to use a cable, not a wire, an additional protective coating will protect against external damage. The procedure should be as follows:

Study of the connection diagram of the lock to the controller. The wires are of different colors, which greatly facilitates the work.

Wiring diagram for electromagnetic lock controller

Cable routing from the lock to the controller. The cable must be placed so that it can be hidden under the door frame trims. For installation on the door leaf, a corrugated pipe or special cable ducts are used, which are attached to the door.

It looks like a cable laid along the door leaf

Installation of all components of the lock connection diagram. Connect the power contacts last to avoid short circuits.

Connect the lock to the power supply and check its operation. If everything is done correctly, a buzzer will sound when the controller is connected to the network.
Disconnect the lock from the power supply, install the controller in its original place next to the voltage source, for example, a 220 V socket, and reconnect it.
Now you can start setting up the electromagnetic lock:
- if the lock is controlled by a card with a cipher-code, it is necessary to press the “Register” button and one by one bring each card to the reader, then press the “Register” button again. The lock is programmed;
- The code lock is configured in a similar way: after pressing the "Register" button, the desired code is entered, which is fixed by pressing the button again.
- invisible locks with a remote control come pre-configured.

Check the function of the configured locking device.

Installed card electromagnetic lock

The connection of the electromagnetic lock is completed.

To install an electromechanical locking mechanism, you will need:

electric or hand drill;
Bulgarian;
hammer and chisel, if the door is wooden;
a set of self-tapping screws;
screwdriver;
pencil.

Having prepared the tools, we carefully study the installation instructions. This work does not require special skills, so you can immediately proceed with the installation, which is performed as follows:

We attach the mechanical part to the door and mark the location of the lock.

For a mortise lock, we prepare a seat using a grinder or a chisel.
We make a control fitting, check the conformity of the seat to the dimensions of the lock.

We drill a hole for the larva and the door station of the video intercom with the camera. On a wooden canvas, the sluice is made with a feather drill, on a metal one - by drilling small-diameter holes around the perimeter.
Using a drill, we prepare channels for self-tapping screws.
We mark and install the fixing strip on the door frame. For a mortise lock, it is necessary to make recesses for the entry of the crossbars.
We mount the lock, fix the parts with fixing screws and self-tapping screws, bring the control wires to the inside of the door.

The lock is fixed with screws

If everything is functioning normally, you can go directly to connecting the product:

We start connecting the electromechanical lock by studying the electrical circuit.

Connecting the electromechanical lock to the power supply

We make key programming. To do this, set the jumper on the back of the magnetic reader to the “Programming” position. We apply one of the keys to the reader for 1-2 seconds, wait for the buzzer. We now have a master key that will allow us to set up the rest. To put the rest of the keys into operation, you must perform the following steps:
- do not install the jumper;
- press the lock opening button, while holding it, touch the reader with the master key;
- wait for the lock to close and the sound signal;
- touch the reader with the key to be programmed.
- Repeat the procedure for each subsequent key.

Electromagnetic Programmable Key Reader Options

To connect a video intercom, you need a 2x0.5 or 2x0.75 cable. We choose a place for installation and determine the length of the cable. To connect, you need two pieces of cable: they will connect the door station with the videophone, the second - the lock with the power supply.

Flat cable ШВВП 2х0.5 is ideal for connecting an electric lock

Using the wiring diagram, we connect the wires exactly according to the instructions. Different manufacturers use different colors to designate connecting cables, so it is important to find in the instructions the purpose of each wire for a specific lock model.

Each manufacturer assigns its own color to the cables

After completing the connection, you need to check the functionality of the system. If everything works correctly, we perform the final installation of all systems as follows:

We put the cable in specialized boxes, fix them on the door and wall.
We drill holes in the wall for mounting the intercom and install it in its original place.

Video intercom controlling an electromagnetic lock and a door station with a camera

The magnetic lock is connected, the system is ready for use.

Self-installation of electric locks can save you a lot of money and acquire skills that will become irreplaceable.

A video will be useful as a visual instruction for installing and connecting an electromechanical lock with an intercom.

An electromechanical lock is a convenient and fairly reliable device., which can be controlled remotely. Also, the device can be easily paired with an intercom, which makes it especially popular. The device and the principle of operation of electromechanical locks are quite simple, which guarantees stable operation for many years.Unfortunately, it is impossible to argue with the fact that if something can break, someday it will break. Electromechanical locks, like any other device that is used on a daily basis, over time may require repair in order to eliminate the malfunction.To determine the malfunction, you need to understand how the electromechanical lock works. Its main part is a usual mechanism, but to control the crossbar, not the usual larva with a key is used, but a solenoid. The key for the solenoid is electric current. When it is fed, the deadbolt is set in motion. To control an electromechanical lock, a special controller is required, which can also fail.As you can see, the device of an electromechanical lock is simple. Several reasons for its failure can be distinguished.Lack of power... Most often, the problem lies in the power adapter or connecting wires. Also, the cause of incorrect operation of the lock can be poor contact caused by corrosion or oxidation of the terminals.Jamming of crossbars... An electromechanical lock, like a conventional mechanism, requires periodic maintenance. This is especially true if the device is used in a dusty room or at the entrance gate. Regular lubrication of all moving parts will significantly increase the life of the lock. It is also worth knowing that well lubricated parts place less stress on the solenoid and extend the life of the solenoid.Broken controller... It is impossible to control an electromechanical lock without a special controller. It can fail for various reasons: factory defect, short circuit or mechanical damage.Unprofessional installation... This problem is hardly rare. Elementary mistakes when installing a lock or laying wires will eventually leave the room without proper protection.Mechanical damage... Despite the sturdy housing, the electromechanical lock can be damaged. Quite often, the unprotected cable is the first to suffer. Fortunately, this is one of the simplest faults. Much more problems will arise in the event of damage to the castle itself.In the event of a breakdown, any repair begins with high-quality diagnostics, and this requires not only skills and knowledge, but also special equipment. If, as a rule, it is enough to lubricate the lock mechanism, then it is often not possible to eliminate the malfunctions associated with the electronic part on your own.If there is no experience in repairing such equipment, the best solution would be to seek help from a specialist. This will save you time and are guaranteed to get the desired result. Image - DIY repair of electromechanical locks

An intercom is the same technique as a camera, telephone, iron or vacuum cleaner, and has its own service life, during or at the end of which all kinds of breakdowns of individual elements occur.

In this article, we will analyze the repair of such fundamental parts as an electromechanical lock and a pipe. Less commonly, the problem occurs in the wiring or outdoor panels.

With the growing popularity of intercoms and their prevalence in apartment buildings, many owners are often faced with such a problem as a broken pipe - the very one through which people outside the house request to enter.

Especially cunning craftsmen can raise the price for a repair high if they discover that the owner of the apartment is neither sleepy nor spiritually aware of the principle of operation of this or that technique. And if the pipe is also of low-quality production and is prone to frequent breakdowns, then you can completely grab your head from how much money is spent on repairs! If this problem is familiar to the reader, then it's time to learn how to repair this protection element with your own hands almost free of charge.

Typical problems include the following:

There is no call from the intercom in the apartment;
The equipment does not respond to the signals of the outdoor panel;
The wrong subscriber is being called;

And they happen due to failures of the intercom calling system, but there are physical malfunctions inside the tube itself. Depending on the model and manufacturer, the handset is modified with LEDs, the ability to mute the sound, change the tone, ring volume and the ability to connect a second handset, having its own ordinary functions - the doorphone door open button and the intercom.

If you disassemble the tube body, you can see an ordinary scheme: a small board, a few wires, a speaker, a switch, a button, a reed switch and everything in the middle of a huge free space. Most often, reed switches, switches, buttons and the case itself break. The main reasons for their breakdown are:

Failure of the entire system;
Mechanical damage.

Most often, the "tongues" of the body, which act as a holder for the tube itself, break. The repair method is nowhere simpler: just solder the broken part into place, and if there is a good superglue, it will be enough, but not for very long. If such a "language" also includes a communication chain, then you will have to use only a soldering iron and with increased accuracy, so as not to cause a breakdown of the entire rest of the system.

Another common tube problem is poor functioning of the door opener button. They may not work the first time or even perform a reset function.

To start repairing, you need to open the tube and inspect the switch. It is usually installed in two positions:

Separate from the board. In this case, it will be enough just to check the density of the soldering of the wires to its legs, and if one of the wires is really badly fixed, solder it.
Tightly wired into the board. There is a high probability of a malfunction of the switch itself, and in this case you have to buy a completely new one in the radio parts store, after carefully removing the broken one from the board.

If, when you press the door open button, the call is reset, and the door does not move, then you need to evaluate the quality of the soldering of the wires near the speaker in the tube. By soldering the wire back, you can completely get rid of this problem.

But there may be a more rare case: broken wire in the speaker coil, and, unlike the first problem, it will no longer be possible to visually identify it, you will have to use the dialing of a multimer or a tester. But the most common reason is the contamination of contacts created to turn off the call in order not to wake up the whole house from a late guest who has a wrong number.

One more problem - reset the call immediately after picking up the handset... Depending on the tube model, a reed switch or under the tongue switch is responsible for disconnecting the circuit when the tube is returned to the base without opening the door. In this case, it is sufficient to simply replace the faulty switch.

Reset when typing an apartment - a situation that occurs immediately after the installation of the intercom and handsets in the house. If the master did not take into account the polarity of many wires and contacts when connecting them, which is important and is the root of the malfunction, then the caller simply will not be able to get through to the required apartment.

Poor audibility during a call - malfunction in the microphone and speaker. On the board in most doorphones there is a trimming resistor, which is directly related to adjusting the balance between the microphone and speaker. Remembering the initial position of the slider, pulling it from side to side and returning it to the original one, you can completely get rid of poor audibility. But it is worth noting that terrible audibility, interference and disgusting sounds can be the result of frugality, the result of buying a cheap intercom.

With the definition of this element, everything is simple - it is a mechanism that directly closes the intercom. There are several breakdown factors, and they can exist both together and separately:

Human. The high permeability through the doors of drive intercoms and the vandalism of some individuals in not particularly prosperous areas leads to the shift of the anchor of the lock along the axis. In addition, most residents completely forget about the need for prevention and maintenance of intercoms;
Natural. In the absence of visors over the intercoms, rain, snow, hail, high or low temperatures, as well as humidity and dirt in the entrance, at least adversely affect the condition of the wiring and fasteners, and under mechanical stress, the fasteners were erased and deformed.
Closer work. The door closer is designed for indoor installation, but it can also work outside. In the absence of seasonal adjustment, the intercom may close poorly in summer, and clap loudly in summer, which also leads to malfunctions of the fasteners.

The first and most necessary step in the repair of any part is diagnostics. Thanks to it, you can determine the plan, duration and cost of the work, and it must be carried out regardless of the obviousness of the ailments.

Repair and restoration work continues with the purchase of parts necessary for replacement, and then - checking the condition of the cable line. You can install new parts yourself, but whether they will start is another question, the answer to which is better to find at the first stages of work.

Under the anchor of the lock, you need to install a rubber lining, thanks to which no external forces will be able to open the door, thereby deforming the anchor or fasteners.

The unevenness of the surface to which the electromechanical lock will be attached must be measured, leveled with a hammer, drilled in the right places, calculating them as accurately as possible several times to avoid distortions. Leaving gaps for the future, you can adjust the position of the lock and the tightness of its fit to the anchor. The installation of the lock is over.

If the cable line is also in poor condition, it must be restored.You need to check the joints, seal them if necessary with electrical tape or corrugated sleeve, broken wires - connect or replace completely if the appearance is unsatisfactory. If everything is done correctly, the mechanism will work instantly.

It remains only to check the work of the closer. If it is not adapted to work on the street, replace and regulate the pressure in the off-season, where the door closing stroke is fast in the first 2/3, the remaining third is slow. This way, loud and unpleasant pops can be avoided in the summer, and the slow, heat-driven closing - in the winter. Repairing the lock will cost about two and a half thousand rubles, together with the pipe - in most cases free of charge.
