Installation of car alarms. Features of installing a car alarm with your own hands

Car alarm is an effective security system. It is often used on modern cars. Perhaps the alarm will not save you from theft, but it will help stop attempts at damage. It often happens that in the yards, children, by chance or not by chance, can hook the car. Also, shelling of cars from pneumatic weapon. With the help of the security complex, the owner will be able to respond in time to the damage. Alarms can scare away criminals - there are many such cases. It is best to entrust the connection of the alarm experienced professionals, but if there are none, you can try to do it yourself. The operation is not that difficult. Let's see how to connect the alarm.

Standards and schemes from different manufacturers

If we analyze the connection diagrams of car alarms from various manufacturers, then it can be concluded that any standard schemes and there is no single unification. Wires of the same color from different manufacturers solve different problems.

A particular brand has its own method of installing and connecting devices.

Installing the alarm unit

The first step is to install the main unit. the main problem for many - where to connect the alarm? It is installed in the passenger compartment, in a place known only to the driver. If this is a serious security complex, then there are several such blocks - they are best placed in different places. This will help buy time when the car thieves will take over. Before connecting the alarm sensor, you need to disassemble the left rack. It is recommended to install it there.

As a standard, a simple alarm unit is hidden inside the dashboard, but other places can be found. It is desirable to fix the block. It can be glued on double-sided tape or attached with self-tapping screws. Also at this stage it is necessary to deal with electric circuit- it indicates how to connect the alarm to power, turn signals, central locking solenoids.

Wire pulling

There are usually many cords. It is better to stretch them in closed, reliably protected from moisture and high temperatures places. It is better to stretch the wiring in the braid, and it is recommended to use plastic clamps for fastening on the body. They need to be tightened at a distance of no more than 20 centimeters from each other. Whatever the alarm, it has redundant wires. The door and trunk opening switches are different wires. But since the function is one, they are connected through one cord. The second one should be cut off. Later, when there are any problems with the signaling, it will be easier to determine possible cause and find the circuit in which there are faults. The practice of installing alarms shows that complete wires are often not enough. Therefore, it is better to purchase additional ones in advance.

Power connection

Everything is simple here. It is enough to find a large thick cable on the fuse box of the car - this is the positive wire. Weight is taken from the body. The wires are stripped and connected using quick-detachable terminal blocks.

Alarm connection points

Consider popular connection points. The main plus for power can be found in the ignition switch. The starter contact with negative polarity is also in this location. The ACC element is located there. The ignition contact with positive polarity can be found in contact group castle.

The regular lock in most cases is connected through a negative wire. But there are exceptions. Doors and their limit switches are controlled by positive polarity, but it is better to double-check everything according to the diagram. The dimensions are connected to the positive wire, and the locations of these wires are marked in the fuse box. In most cases, these points are enough to solve such a problem as connecting an alarm to a VAZ (whether it is a "Classic" or a modern "Vesta").

Connection of external light signals

In almost all devices, the indication is carried out through the direction indicator lamps. It is better to use two wires - each is responsible for its own side. It is advisable to connect through diodes to avoid shorting the sides. It is more rational to connect through the dimensions - they have less power consumption, and you also need one wire without diodes to connect.

Connecting to the central lock

Perhaps the alarm will not save from but will make the life of the driver more comfortable. Many systems have central locking control. Let's see how to connect the locks to the alarm. We will assume that the solenoids have already been installed.

The first step is to understand the colors of the wires and what commands they perform. For this, it is better to use a multimeter. The search algorithm for the desired contact is quite simple: the device is set to the resistance measurement mode. The minus is connected to one of the contacts, a button is pressed that closes the door. With a multimeter, you need to look for zero resistance. After that, the button can be released. When the resistance is infinity, this is the desired contact. They are also looking for a second contact. This is done in a similar way.

Then the threshold is removed from the driver's side. Next, they find the necessary wires that were determined in advance. Alarm wires are connected to them, which are responsible for opening and closing doors.

How to connect the Starline alarm?

The Starline company produces popular modern security systems with an autorun function, as well as "quick dialogue" functions that exclude the possibility of hacking the security complex with a code grabber. Most models have 60 or more standard and programmable functions.

For installation, you will need an alarm, a solenoid on the driver's door, a soldering iron and soldering materials, protective diodes, electrical tape. Before connecting the alarm, remove the plastic of the steering shaft, unscrew the screws for fastening the dashboard, as well as other nuts and screws. Then, an LED is installed in the windshield rack, as well as a shock sensor. A service button is installed anywhere. These security complexes has an antenna. It is better to mount it on the windshield. Next, connect the wires from the 18-pin connector according to the instruction diagram. So, the black wire is connected to the mass, the red one - to the "plus". And further according to the scheme.

How to tie a keychain?

In addition to the fact that the driver faces the task of installing an alarm, he must solve another problem - how to connect Sometimes they are not programmed. A key fob or radio transmitter is the main device that allows you to control the security complex. If the alarm is new, then reprogramming is not necessary. If the car is used, then it is better to reprogram.

To begin with, the block is transferred to the service mode, which allows you to perform Maintenance devices. To switch to this mode, there is a special combination of pressing certain buttons - each manufacturer has its own.

First you need to disarm the alarm. The Valet button is pressed several times, and then the ignition is turned on. If you hear several beeps, you have successfully logged in. Next, you need to press a few buttons indicated in the instructions, after which a beep will sound. The key fob is programmed and the system remembers it. You can freely use the alarm.

Conclusion

Here's how to wire an alarm with your own hands. In general, the process is simple and does not require special skills, but it is not always possible to set everything up correctly on your own. If the car has a lot electronic systems better to trust the professionals. But a simple budget system can be connected independently, in half a day without experience.

Installing an alarm on a car is an opportunity to protect the vehicle from theft and, thereby, provide peace of mind to the owner of the car. The problem is that standard devices (installed at the factory) guarantee a minimum level of security and offer a small set of options. This is not enough to protect the vehicle from intruders. The best solution is to install a professional type car alarm.

If a security system is already installed on the car, but it is morally and physically outdated, think about replacing it. Otherwise, the car becomes easy money for car thieves who have the required skills and equipment to break into the car and disable the alarm. At the same time, do not rush into the choice. Buying and installing a car alarm is a responsible process that should be approached fully armed.

How to choose a security system?

First decide on suitable model alarms. To do this, prepare a sheet of paper and write down the requirements that should apply to the device:

• work radius.
• Possibility of automatic engine warm-up.
• Protection against digital hacking (implemented by installing an anti-scanner).
• Automatic blocking.
• Autograber and other protective functions.

Once the requirements are determined, study the pricing policy to determine the potential costs of purchasing the model of interest. Next, study the technical documentation for the devices, read the reviews of real users and make a decision. If the security system is suitable for its characteristics, has a sufficient amount of options and has no complaints from other car owners, buy it.

Features of GSM alarms

For many hosts expensive cars The best decision- installation of a car alarm with a GSM module. The main purpose of the device is to ensure stable communication between the owner vehicle and the central block of the security system. In addition, in case of theft, it is possible to quickly determine the location of the car and return it to the owner.

The main disadvantage of GSM systems is high price. Installing an alarm on a car results in a large amount, so many car owners prefer budget options. It turns out that the installation security systems with a GSM module is relevant only for expensive cars. If the cost of buying an alarm and setting it up are commensurate with the price of the vehicle, then there is no need for such expenses.

Installation methods

When installing a security system, there are always two ways - to entrust the work to specialists or to do it yourself. Installing a car alarm with the involvement of craftsmen has several advantages:

• Quality assurance of the work done. Installation is carried out by specialists who know the features and weak spots such systems.
• Minimum costs time (installation takes no more than 2-3 hours).
• Security system warranty. If there are problems found during the warranty period, you can always return to the service station and have the masters fix the problem for free.

There is only one minus - the need for additional costs. The services of specialists are expensive, so with this installation method you will have to say goodbye to a certain part of the budget.

Second option - self-installation which is available to everyone. It is enough to have the skills to perform such work and the right tool (see video for DIY alarm installation below).

What are the advantages of installing a security system with your own hands?

Car owners are increasingly opting self-assembly alarms. The reasons are as follows:

• Acute shortage of funds (desire to save money).
• Love for technology. Some people love DIY, and installing a car alarm is no exception.
• Non-standard design, when it is impossible to attract craftsmen to perform work.

First reason. When choosing a security system, I want to buy quality device, which often has more high price. But due to the limited budget, there is enough money to buy the system, but installation work done independently, without the involvement of a specialist. As a result, it is possible to save money and get at the disposal of a security system of a higher level.

The second reason mentioned above is the desire to do everything with your own hands. Such situations are very common. Many car owners are ready to sit for hours near the car, doing its repair. For them, this is rest and relaxation, an opportunity to protect themselves from current problems. In addition, self-installation of a car alarm is also a reason to assert yourself, to believe in yourself. Yes, and using a security system installed and configured by oneself is more convenient and pleasant.

The third reason is the non-standard device. The situation is the following. You dream of a high-quality security system, but there are difficulties when choosing a device. After months of searching, the understanding comes that the alarm is easier and cheaper to do with your own hands. But there is another problem related to the implementation of plans. If you have certain skills and knowledge, it is realistic to do the job.

How to mount a security system with your own hands?

Before installing an alarm on a car, carefully study the documentation and understand the system electrical wiring vehicle. After that, deal with the scheme of the security system and decide on the algorithm for subsequent actions.

First stage- determination of the location of the main signaling unit.

As a rule, it is mounted near the fuses, which allows you to solve two problems at once - to simplify system maintenance and speed up installation work. Due to the proximity of the safety unit and the control unit of the security system, less problems with voltage applied. There is no need to waste time and deal with the wiring of the machine, because the main nodes are located next to each other.

• Connect the system responsible for triggering the horn to the correct connector.
• Connect the power wires to the central lock that opens and closes the doors.
• Switch the turn signals, which also work when the security system is activated.
• Connect the supply wires (no voltage yet). When working, observe the polarity. If you confuse the "minus" (case) and "plus", then the risk of the device failure is high. If in doubt about the correct connection, use special device- tester or voltmeter.
• Connect mass. To solve the problem, use a separate conductor, which is connected to the alarm at one end and to the machine body at the other. To fix the wire, use the "eight" or "six" bolts. For greater reliability, corrosion protection and reduced risk of unwinding, treat the bolt with paint.
• Connect the security system to the ignition of the car. To solve this problem, pull a pair of wires from the central unit to the mentioned node. At the same time, follow the scheme that comes with the security system.

The next step in installing an alarm on a car is to connect a device that receives and transmits information from the central console.

To increase the range, mount the transceiver on the windshield of the vehicle. Lay wires separately from other conductors. The reason is protection against potential interference, which increases the risk of false alarms of the security system.

The subsequent installation of the car alarm is done as follows:

• Choose a place for the shock sensor and put it. The optimal point for installation is behind the torpedo of the car. The device is fixed using the fasteners supplied with the device.
• Install the signal part (the ideal place is under the windshield wiper mounting). To solve the problem, disassemble the mount, dismantle plastic element, and at the final stage, mount the siren. Connect the device by laying wires through existing channels. As a rule, two wires go to the wipers, and in addition lay a couple more (to power the alarm system signal). After installation is completed, install the previously dismantled units in place, following the reverse algorithm.
• Mount the limit switch under the hood, which controls the fact of opening/closing of this body element. The place for mounting the device is above the headlight on the left side. When the hood is closed, the chain is closed. But as soon as an intruder opens the hood to disable the system, the latter will work and notify the owner of an attempted hijacking.
• Connect the alarm and the power unit. To solve this problem, include a relay group in the system that controls the gasoline pump. When the alarm is activated, the relay contacts close, the power unit is blocked, and it cannot be started.

For more expensive cars, when installing a car alarm, a redundancy system is provided. Thanks to such foresight, the risk of vehicle theft is reduced, and the efficiency of the security system is increased. In Russia and the CIS countries, this practice is not popular. The reason is the high cost of the device, which not all motorists are able to pull.

RESULTS

Installation of a security system is a process that can be done by hand, without the involvement of service station masters. To successfully solve the problem, only three components are required - the availability of theoretical knowledge, practical skills and free time. If all of the above is present, it remains to do the work yourself and save a large amount on visiting the service station. The final result will surely please the eye and raise your own self-esteem.

Installing an alarm is a rather time-consuming process that can be difficult for a novice motorist to handle. But at right approach even a beginner can do it right. We suggest that you familiarize yourself with the issue of installing an anti-theft system in more detail - what a motorist needs to know, how to correctly determine the place and how to install it.

What does a beginner need to know when installing?

Installing an alarm on a car is a rather important step, which not every car enthusiast can decide on, so if you have made such a decision, then consider a few nuances. In general, the procedure, as mentioned above, is quite complicated and requires certain knowledge and skills. Today, the automotive market offers customers a huge variety of brands of car alarms. If you want to properly install a car alarm on a car in order to avoid repairs later, first decide which brand you prefer.

The market today is literally replete with a variety of brands, including Sheriff, Alligator, Tomahawk, Panther, Starline, Shere Khan, Monguz and many others. The above company names are not in vain, because these brands have long proven their reliability and practicality. Of course, dozens of other systems can be found on sale. But if you analyze consumer reviews on the network, you will understand that in most cases it is the alarm systems of these companies that work reliably and without the need for repairs.

But besides the fact that you can find so many brands on sale, there are about the same number of installation schemes for anti-theft systems. Therefore, before installing the alarm, it must be taken into account that connectors with the same color in different anti-theft systems may be designed for different functions.

Installing the immobilizer as a whole is a very responsible procedure, because the safety of your vehicle depends on it. To avoid possible repair in the future, give preference only to trusted brands, this is very important. In addition, you should not buy a system from unverified sellers, as this will be fraught not only with the need for repairs, but also with other equally serious problems. Therefore, one way or another, installing an alarm with your own hands, as well as choosing an anti-theft system, must be carried out in accordance with the scheme.

Moreover, experts recommend considering the scheme as the main document when choosing an anti-theft system, that is, relying only on it before buying. If you decide to use a homemade car alarm, then you need to be most careful. First, you need to know everything about installing a car alarm, in particular, where this or that output goes. Secondly, it must be remembered that incorrect actions during installation can lead to irreversible consequences. Well, if you just need to repair the system, but then short circuit, which may occur in homemade device, can even cause a fire (the author of the video is Rinat Farukshin).

So, in order to avoid possible repairs, it is necessary to be conscious of the choice of both an anti-theft system, as well as a connection scheme. As for the installation of GSM systems at home, in this case you need to understand what this device is in principle. Indeed, in it, individual sensors perform certain functions, it should also be borne in mind that after installation you will have to program the entire system, as well as perform other actions.

If you feel that this may be a problem for you, then installing an anti-theft system on a vehicle on your own would be better to exclude. The best option will turn to specialists, this will avoid possible repairs in the future for a certain amount of money, but believe me, it's worth it. Well, or you yourself will have to figure out all the schemes and tricks of installing a GPS system. In general, self-installation of an alarm system is divided into several stages, we will talk about each of them separately (the author of the video is Michael MNS).

Installation instructions

Materials and tools

If you are interested in learning everything about installing a car alarm, then before you start the process, you need to pick up all the necessary tools. First of all, you will need the anti-theft system itself, as well as the installation and operating instructions that come with it. The alarm installation manual is the main component that you may need during installation.

In addition, prepare in advance:

1. Multimeter. It is important not only to prepare the device, but also to understand its principle of operation, as well as to be able to put it into practice. At a minimum, you will need to measure conductivity and voltage. If you decide to buy a device before performing repairs, then it would be better to give preference to an electronic device. A pointer multimeter is not so convenient for measuring conductivity.
2. Wires. Make sure you have all the necessary wires. It should be noted that the wires that come with the kit may not do the job, as they are usually too short and do not fit in length. Therefore, we recommend stocking up with additional wires.
3. You will also need foam rubber, but not too thick. This material is necessary in order to pack central block anti-theft system and protect it from dirt and moisture. By the way, regular exposure to moisture can lead to the need to repair the unit. Experts recommend using black or gray foam rubber so that it does not stand out in the car interior.
4. The insulation is strong and durable.
5. Double-sided tape.
6. Stationery knife - required for wiring.

Determination of the installation location

Self-installation of the alarm also implies right choice places. In this case, you do not need to come up with something new, since there is no need for it. The central block of the anti-theft system is always mounted behind the console - this is the most convenient place, since in case of repair it will not be difficult to get to the block. As mentioned above, before starting work, it is necessary to prepare foam rubber.

Actually, you will need to wrap the entire block with foam rubber, so decide in advance and try on how it will be convenient for him and in what place it is optimal to install it. Make sure that the block can be securely fixed and that it does not interfere with anything.

Installing an alarm on a car requires first of all determining the installation location of the anti-theft system.

In this case, you need to take into account a few specific points, which are described below:

1. The central unit must be installed in the interior of the vehicle, while the place of its installation must be hidden. It is important that no one can see the block. You need to think about this point in advance, since it is important to install the block in such a way that it would be difficult for a thief who tries to get into your car to get to it. Of course, it is not so difficult to determine the location of the block by wire, but it will take time to get it out and turn it off.
2. To prevent damage to the unit, please note that it should not be located in close proximity to various moving components and parts. This refers to all kinds of traction, cables and so on. Constant exposure external factors may damage the device.
3. As we said above, the place for the block must be selected wisely. The device must not be located in close proximity to various sources moisture or heat, that is, first of all - stove. Air vents from the air conditioning system may adversely affect the operation of the unit.
4. It should also be noted that the device should not be installed near a source of receiving or emitting radio waves. We are talking about antenna wires, mobile phones as well as radio stations. They can not only drown out the work of the anti-theft system. But they can also be used by attackers to intercept the digital signal from the alarm key fob.
5. Remember that the main connections to electrical system the vehicle will be carried to the dashboard. Therefore, in any case, you will need additional wires, which should be stocked up in advance (the author of the video is avtozvuk).

Also have certain moments which must be taken into account when installing an anti-theft system.

1. The installation of wires is always carried out in a specially designated place between the end of the door and the vehicle body. Because the doors are constantly opening and closing, there is a high chance of kinks forming. To avoid this, it is necessary to use special rubberized through pipes. Also, bushings with the necessary bending radius will not be superfluous. This way you can avoid possible problems when operating the anti-theft system in the future.
2. An important point is the installation of solenoids. It is carried out in the doors, it is important to consider that the solenoids should be located as far as possible from the pull button designed to open the door.
3. Now for the cabling. All wires must be laid where moisture does not collect, this is very important. If you can't tell exactly where a dry place is in your body, then you need to choose it so that it is at least potentially dry. The wiring itself, as well as the direction, is made using plastic wires.

How to choose an anti-theft system?

First of all, before buying an anti-theft system, you should decide on the budget, the functionality of the car alarm will largely depend on it. Therefore, before you buy a device, you should note in advance all the characteristics that apply to it.

This list includes:

1. The range of the system. Usually, the larger the radius, the better, because even if you move away from your car, you will always know about the state of its protection.
2. Automatic engine warm-up function becomes popular in recent times among our car enthusiasts. Thanks to it, you can set the alarm so that at a certain time the engine starts on its own. This is especially true in winter, when you don’t really want to get into a cold car.
3. Auto-lock option— if the driver forgot to turn on the alarm, this option activates the protection on its own.
4. Protective functionality. For example, it can be an autograbber that can be used to diagnose the installed system.
5. Antiscanner. Thanks to this feature, the system will be protected from digital hacking if attackers try to intercept commands. Before buying, check the reviews of car enthusiasts to know which systems of which brands work well and which ones are characterized by malfunctions.

Video "Installation of an anti-theft system with autorun with your own hands"

How to properly install a car alarm with an autorun function at home - find out from the video (the author of the video is Roman & Ko).

Alarms for cars perform the function of alerting the owner of the vehicle about the penetration of unauthorized persons into the inside of the car. They are different types, many manufacturers are engaged in the production of security systems for cars.

If the owner of the car found the right security system for himself, brought it to his home, this means that the system must be installed.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The motorist can trust in this matter professionals or their loved ones. But this is not particularly necessary, because the instructions for installing the alarm are always attached to the security device.

What the owner of the vehicle needs to know about alarms

Models of security, automotive systems of different brands and types differ from each other not only in terms of appearance and equipment.

Each installation can have its own scheme, using which the owner of the car will be able to place all parts of the alarm system in the correct order.

The pitfalls of this process can be hidden not only in the schemes, but also in the following indicators:

• in different alarms, wires of the same color can perform different functions that will not be identical;
• some types of alarms require more effort in terms of installation on the part of the owner of the car, because they may have additional elements responsible for various functions of the system;
• the connection diagram of the alarm system itself may not be suitable for a certain type of car - you should choose a security system according to specific model cars.

If a person has taken into account all the features of his vehicle, considered a number of possible complications for working on installation and realized that he can do it, installing an alarm with his own hands will not be a problem for him.

Preparation of tools for installation work

In order to quickly, correctly, and qualitatively install an alarm on your own car, you need to stock up on endurance and strength, and also prepare the following tools:

Having prepared an alarm with an auto start function for installation, the owner of the car can install an alarm on the car in a few hours. It is desirable that at hand were not only necessary tools, but also a diagram that will help to do everything right.

Installing a car security system on your own - in what places is the connection made

Automotive, security systems with auto start work on the same principle and their installation scheme is the same. The alarm connection points on the car are as follows:

1. Free cavities that are behind dashboard.
2. Parking brake section.
3. Places for locking and unlocking doors.
4. Stator and turn signals.
5. Near the door and trunk opening sensors.
6. Near the brake pedal and parking brake.

All these points for signaling with auto start can be found by the owner of the machine using the indicators of the UCH module or by looking behind dashboard. Alarm connection points in cars of most brands are located in approximately the same places.

Making the process of installing a security system with your own hands

By choosing a car alarm with auto start and feedback, a person should take care of her correct installation. The general algorithm of actions, which involves the installation of a car alarm with feedback and an autorun function, is as follows:

• the instrument and steering panels are removed;
• the lower lining of the steering column is carefully removed;
• installation in progress system block alarms in hidden meta;
• wires are laid, protected and extended;
• a shock sensor and a siren are installed in the luggage compartment;
• connect the wires of the required colors, according to what the diagram shows, to special points on the machine;
• alarm wires are connected to the power supply system of the machine.
• the functionality is checked by auto-starting the alarm with feedback.

Self-installation of an alarm on a car requires a lot of effort and a supply of temporary resources on the part of its owner. The installation diagram helps to carry out each process correctly, step by step.

It will be easy to set the alarm on the car yourself if you use the instructions for the security system.

Additional facts to keep in mind when installing an alarm with auto start

Alarm for cars with auto start function and feedback requires special attention during installation. Every owner who wants to protect his car from theft by installing a powerful car alarm should know that her right job depends on the installation method. In addition to what is written in the instructions, a person must be guided by the following rules:

Installation cards for car alarms are present in the instructions for the device. If it will be easier for the owner of the car to use their Internet schemes, this is also good decision. Each driver will be able to independently install alarms with an autostart function and feedback. To protect his car, he needs the security system itself, a diagram for its installation and a set of tools. You need to check the feedback and autorun functions immediately after mounting the system. Three beeps - installation failed. If only one signal everything is fine.

Self-installation of a security system for a car with auto start and feedback is possible, but for this you need to be patient and do everything according to the rules.

The beloved character of 12 chairs, Ostap Bender, said: “A car is not a luxury, but a means of transportation.” Years later, it becomes more and more difficult to agree with this statement, because if it were not for the high cost of cars, then they would not have been stolen. Unfortunately, the statistics of theft is growing inexorably and today it is rare to meet a motorist who has not installed a security system on his car. Fortunately, there are a lot of alarms today - these are also ordinary “tweeters” that react to a kick with a foot or broken window and more "serious" complexes that allow you to turn off the engine remotely, as well as products equipped with GPS / GSM modules. The cost of such systems differs depending on the number of sensors, range and many other factors. In any case, it is difficult to say that this is a cheap pleasure. In addition, you will have to pay for a specialized installation. Not surprisingly, many drivers decide to do the installation themselves.

Everyone knows where you can install an alarm on a car, it can be a regular car service or a specialized dealership. And of course, every motorist, having familiarized himself with the prices, comes to the conclusion that "you can try it yourself." On the one hand, according to experienced "drivers", self-made methods make it possible to install not according to a well-established scheme known to every hijacker, but using tricks and tricks that are different from the standards. There is some truth in this, but, on the other hand, you should also know that if you are unsure of your abilities or a friend volunteered to help you, who also overestimated his capabilities, you risk disabling not only the security system, but also all on-board electronics of the car. So it is better to think three times before making such a decision. If you are confident in your abilities, then first of all study the instructions in detail and decide on the connection points.

Healthy! It should be borne in mind that some manufacturers are categorically against self-installation. For example, Pandora systems can only be installed at a dealership, without which you simply cannot purchase such a security system in an official store.

What you need to know before installing an alarm

Before installing an alarm on a car, you should not rely on videos or tips on blogs. The good wishes of car owners are not general instructions and when connecting the "signaling" to different brands cars, not only the type of car is taken into account, but also the year of its release, type and much more. The fact is that the connection scheme in different situations will be different. This is not just done. If all systems work on the same principle, then it will be much easier for hackers to bypass them. Therefore, it is best to familiarize yourself with the standard wiring of your car and the instructions for a specific alarm.

Important! There are many schemes for connecting security systems, where the colors of the wires may differ from generally accepted standards. Some manufacturers create new wiring diagrams that even experienced installers cannot figure out.

Here is an example typical scheme connections modern signaling StarLine, model A91.

It can be seen from the diagram that only those wires that are supplied with it in the kit are marked with colors. The wires to which the connection is made, and it is they who are the wires electrical network vehicle are indicated by black lines. Therefore, when carrying out work, it will be necessary to combine the two existing schemes (an alarm circuit and a car electrical circuit).

Be sure to use electronic meters for "ringing" so as not to confuse anything. It is not recommended to use the usual "honey".

The main alarm connection points are as follows:

• "+" - positive polarity (location point in the engine ignition switch);
• starter - negative polarity (location point in the ignition lock);
• ACC - positive (point in the ignition switch);
• ignition - positive (can also be placed in the ignition switch);
• central lock - negative;
• doors - positive;
• dimensions - positive (location point in the dimensions switch);
• brake - positive (location in the "frog").

It is also better to immediately decide where you will place all the sensors and the car alarm unit itself. And also prepare all the necessary tools.

Materials and tools required for alarm installation

Regardless of the manufacturer of the selected security system, in its kit you will find:

• Control block;
• sensors (motion, impact, opening doors or windows, etc.);
• signal transmitter and receiver;
• sound device;
• a set of wires;
• additional control panel;
• instruction.

Since the instruction is the most important person involved, without which self-installation and repair of an alarm on a car will be impossible, you should make sure that this document is Russified.

From the materials you will need:

• a measuring device (multimeter), which is better to choose an electronic type, and not a pointer;
• additional wiring, in case the standard wires are not enough (and this is likely to happen);
• dark foam rubber for reliable packaging of the alarm unit;
• high-quality electrical tape and adhesive tape;
• dismantling tools various panels, doors and other elements;
• end key;

Additional wires may not be needed, but for this you need to determine in advance where you will install the alarm unit and its other elements, calculating how much wiring this will require.

Where is it better to place an alarm in a car (general installation algorithm)

Here you can’t especially clear up, since the central unit is best installed behind the dashboard. Before fixing it, wrap it with foam rubber and make sure that this element does not touch anything and is held securely.

When determining the place where the signaling will be placed, the following recommendations should be taken into account:

• It is advisable to install the control unit in the maximum hard to reach place behind the dashboard. It is easy for hijackers to figure out its location by wire, but if this element is difficult to get, then attackers will not want to waste time.
• Do not place the control box near moving parts, such as cables, rods, and so on.
• Installing the unit near sources of heat and moisture is also not recommended, so bypass the air vents.
• Do not place the unit near sources of receiving or emitting radio waves.
• If the connection to the electrical circuit of the car will be made through the dashboard, then this will require additional wiring.
• When installing wiring in doorways(in the body) bending can be avoided with the help of rubber tubes and bushings with the required bending radius.
• When installing the solenoids, stay away from the door pull button.
• It is necessary to lay the wiring in dry places of the body. Fastening is best done with plastic clamps.
• It is also desirable to install a shock sensor behind the dashboard in the center of the car or in the engine compartment.
• "Buzzer" is recommended to be installed in the electric wipers.
• The signal receiver is glued on the windshield (in the left corner).

After all the elements of the security system have been installed, they must be connected. Don't forget to connect the wires to the car's lights, as they play an active role in alerting you to a theft attempt.

If you have become the proud owner of an alarm with auto start, it is important in no case to break the polarity. In addition, GSM "signals" require more experience. You must know which elements perform certain functions, understand the programming of such systems and other nuances. Understanding all the intricacies of security systems with GSM modules is not easy, so you should first weigh the pros and cons.

In custody

As you can see universal instruction for connecting all alarms to all existing car brands does not exist. This is not a whim of manufacturers and no desire of car services to cash in on motorists, all these measures are taken with one single goal - to protect the vehicle from theft as reliably as possible. Therefore, if you need to install an alarm on a car with your own hands, do not be guided by only one read article or notes of “experienced”. There are a huge number of video instructions for specific car brands on the network, which are better to watch before installation.
