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 circuits and a singleunification does not exist. Wires of the same color from different manufacturers solve different problems.
A particular brand has its own method of installing and connecting appliances.
Mounting 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.
Standardly, 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, you should deal with the electrical circuit - it shows how to connect the alarm to power, turn signals, central locking solenoids.
Wire pulling
There are usually a lot of cords. It is better to stretch them in closed places, reliably protected from moisture and high temperatures. 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 limit switch for opening the door and trunk are differentwires. 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 alarm, it will be easier to determine the possible cause and find the circuit in which there are malfunctions. 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
It's 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.
Manufacturers recommend taking the "plus" and ground from the ignition switch. You can also find other connection points there. When installing, use a multimeter. With it, you can conveniently and safely find the right wires.
Alarm connection points
Let's 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 block 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. Dimensions are connected to the positive wire, and placesthe locations of these wires are marked on 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 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.
Connection to the central lock
Perhaps the alarm will not save from car theft, but it will make the driver's life 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 are already installed.
First of all, you need to understand the colors of the wires and what commands they perform. For this, it is better to use a multimeter. The algorithm for finding 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 the same way.
Then withthe driver's side remove the threshold. 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 materials for soldering, 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?
Besides the fact that the driver faces the task of installing an alarm, he must solve another problem - how to connect the alarm key fob? Sometimes they are unprogrammed. 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 notneed. If the car is used, then it is better to reprogram.
To begin with, the unit is transferred to the service mode, which allows you to perform maintenance on the device. 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 your own alarm. 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 on your own, in half a day without experience.
