Every car has a button alarm. When it is pressed, the direction indicators and two repeaters located on the front fenders start flashing at the same time, for a total of six lighting devices. Thus, the driver warns all road users that he has some kind of non-standard situation.
When does the hazard warning light come on?
Its use is mandatory in the following situations:
- if happened ;
- if you had to make an emergency stop in a prohibited place, for example, due to a technical malfunction of your car;
- when at night you were blinded by a vehicle moving towards a meeting;
- also includes an emergency light signaling in the case of towing by a power-driven vehicle;
- when boarding and disembarking a group of children from a specialized vehicle, at the same time, an informing sign “Transportation of children” must be attached to it.
What is the alarm button hiding?
The device of the first light alarms was quite primitive, they consisted of a steering column switch, a thermal bimetallic interrupter and light direction indicators. In modern times, things are a little different. Now the alarm system consists of special mounting blocks, which contain all the main relays and fuses.
True, this has its drawbacks, so, in the event of a break or combustion of a section of the circuit that is located directly in the block, to repair it, it is necessary to disassemble the entire block, and sometimes it may even require replacement.
There was also an alarm emergency shutdown button with outputs for switching circuits of lighting devices (in case of a change in operating mode). Of course, it is impossible not to name the main components, thanks to which the driver can notify the rest of the participants. traffic about the ongoing non-standard situation -. They include absolutely all the direction indicators that are on the car, and an additional two repeaters, the latter are, as already mentioned, on the surface of the front fenders.
How is the alarm system set up?
Due to the large number of connecting wires, the modern alarm circuit has become much more complicated compared to its prototype, and is as follows: the entire system is powered only from the battery, so you can ensure its full operation even if the ignition is off, i.e. while the vehicle is parked. At this time, all the necessary lamps are connected through the contacts of the alarm switch.
When the alarm is on, the power circuit works as follows: voltage is supplied from the battery to the contacts of the mounting block, then it goes through the fuse directly to the alarm switch. The latter is connected to the block when the button is pressed. Then it, again passing through the mounting block, enters the relay-breaker of turns.
The load circuit has the following scheme: the alarm relay is connected to contacts that, when a button is pressed, come into a closed position between themselves, so they connect absolutely all the necessary lamps. At this time, the control lamp is also switched on in parallel through the contacts of the alarm switch. The connection diagram for the alarm button is quite simple, and it will take you no more than half an hour to master it. It is necessary to remember its significance, so be sure to monitor its condition.
When buying a car, so that it is not stolen, it is advisable to immediately order the installation of a security alarm in the salon where the car is purchased. This may not give a 100% guarantee against vehicle theft, but it will definitely complicate the task of the hijacker. It is the presence of an alarm on a car that often makes thieves reluctant to mess around with it for a long time. But if you want to save money, then you need to know how to properly connect the alarm yourself.
This is possible if you understand electrical circuits, have the skills to work with a soldering iron and the necessary set of tools. True, you will have to spend quite a lot of time installing the alarm, since you will have to disassemble all the door cards, and installing additional equipment yourself will cost the removal of the warranty from the car. Now “signals” are even put on mopeds. But how to turn off the alarm on the scooter, and not only on it, if it has failed and the car will not start?
It is for these purposes that a button with the inscription "VALET" is included in the kit of any security system. Usually, it is installed in a secret place, which only the owner of the car and the alarm installer should know about. The instructions for the "signaling" describe how to use this button to disarm manually. But there are situations that the failure of the alarm system is very serious. In this case, you need to know how to reset the alarm.
Security alarm is a mini-computer that can be restarted just like a normal personal computer. You just need to remove the positive terminal from the battery and wait 5 minutes. Then, put the terminal back in place. If the security system has not started to function in standard mode, then you can thoroughly fix the terminal on the battery. If not, then repeat the reboot procedure again. And now about how to set the alarm time. At the very beginning, you need to program the car alarm. Next, select a function, you must press the key fob button as many times as necessary. When pressed, the LED will blink.
And it happens when the system stops perceiving the key fob. How to bind the key fob to the alarm again? This can be done very simply. First, open the driver's door and disarm the car manually. Then close and open the door locks by pressing the buttons on the doors. Then, turn the ignition key to the working position, and back to the parking position (3 times back and forth with an interval of no more than 10 seconds). After that, having opened the door, block it 3 times (with correct work system, it unlocks the door within 2 seconds). Then, press the key fob button (if there is a response from the system, then the key fob is successfully linked).
Now it won't be too hard. It is enough to purchase a special device in the store, for example, Duo Digital, which is mounted on a computer monitor. This gadget monitors all movements on the monitor and transmits the necessary signals to the computer.
Now it is fashionable to drive a car to the salon so that an alarm is set there. They do it for some $100 and in less than a day. And then the bewildered car owners cannot figure out why there were malfunctions in the operation of the car or "signals", and even more so they cannot say where the blocks and sensors of the system are located. In addition, if a naive economical car owner entrusted the installation to a "garage service", then it is likely that the location of the signaling blocks became well known to intruders - acquaintances of garage masters.
So, who is interested in setting up the alarm on their own, in order to know all the nuances and not get confused somewhere on the track, read on.
First, let's decide on the location of the main block. Decide for yourself, I will only suggest that it should be in the cabin and not available for quick access so that thieves cannot quickly turn it off. However, they can use other methods of neutralizing the signaling, for example, disconnecting the battery. The solution to this problem can be an autonomous siren and an alarm system with two-way communication or GSM notification.
When choosing the location of the main unit, you must also take into account the length of the standard wires of the control LED, antenna unit (for alarms with two-way communication), shock and microwave sensors. All these wires can, of course, be extended.
The next question is the siren. We put it in the engine compartment so that it is not accessible from the outside (check carefully!), its bell does not "swallow" dirt and, of course, so that the sound from it has the opportunity to spread. It would be useful to install an autonomous siren.
Now we will decide with the power supply of the alarm. From a cigarette lighter? In no case! We lead a separate power wire to the battery. To do this, you can use the technological holes under the panel. Getting to them is difficult, but quite possible. But DO NOT use the hole where the headlight leveler hoses go: this hole is easily accessible from the wheel well, which means that a thief can de-energize the alarm, and all your efforts are in vain.
We pull the ignition switch indicator wire to the ignition switch and cut it in there.
For the front limit switch, we lead the wire into the engine compartment along with the alarm power wire. We put a separate limit switch next to the limit switch for the engine compartment lamp (you don’t need to connect it to this limit switch, including because it often works poorly, it sticks, and split seconds are important for signaling when triggered).
We put the tailgate as shown in the photo. We lead the wire along the left side along the floor. Trunk lighting can be connected to the same limit switch, if you plan one.
The signal LED can be installed on the instrument panel trim. Please note that there the LED is not always visible from ground level and from the first floor. First you need to test its visibility in different places, for example, on a counter, on a panel visor, etc.
We connect the wires of the dimensions not to the dimensions, but to the turn signals - they are more noticeable. The connection is conveniently made near the alarm button (pins 4 and 12), or you can connect to pins 9 and 2 of connector X9 of the mounting block.
It is better to use separate limit switches as door opening sensors, and not connect to regular ones. This is required for models with the APS-4 immobilizer. It is impossible to connect directly to the wires of the limit switches: there will be problems with arming. There are circuits to get around this, but you are tormented to get to the APS wires under the panel behind the skin.
It is also worth noting that the limit switches can be installed not as shown, but on the rear pillar (rear wing for 2108), as is done in foreign cars. Then the limit switches will work earlier when the door is opened.
Next, we put activators that will open / close the door locks. But in the VAZ-2108 there is no wiring in the door. Well, there isn't one! Well, if you come across a used car, and the previous owner did the wiring. I had a used car, but it was from Finland, and people there don't need alarms, believe it or not. I had to do everything from scratch, and this is pretty steamy, because. Initially, the condition was set: do not remove the instrument panel. The photo shows where the holes are drilled. Worth noting - not very successful, because. in the doors, the wires fall into a blind cavity and they have to be led out through the hole. However, this is not scary. In the wing from the inside of the cabin, if you bend the skin, you can find technological holes, through which the wires are brought out. Do not be afraid: carefully open the skin, everything will be found, and then close it without consequences.
The door activators themselves are easy and simple to install. We look at the photo. Something from a "penny" was used as a rubber washer - something that came across in a store. Activators according to this scheme work properly and without problems, incl. in winter.
And finally, do not forget that any alarm is easily bypassed by hijackers. Do not rely on her, she will not protect against theft, and in case of theft from the passenger compartment she will only warn.
Impressions and experience of use
The alarm has been in service for almost 4 years. There were no false positives or failures. The shock sensor has been repeatedly tested in combat conditions. Somewhat annoying is sometimes a small communication distance, to which there is no answer yet. Perhaps interference in the city, but maybe not.Materials and cost

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 weapons is not uncommon. 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 to 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, we can conclude 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 is 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 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 the contact group of the lock.
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 systems have 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 of electronic systems, it is better to trust professionals. But a simple budget system can be connected independently, in half a day without experience.
