Car alarms are today one of the most effective anti-theft systems in a car. A modern device can provide maximum protection against hijacking. However, in order to meet expectations, you first need to choose a good alarm. But to purchase a device is half the battle. The alarm still needs to be set. How to do it right, let's take a look.
DIY car alarm installation - preparing tools
First you need to prepare all the necessary devices and tools. In our case, for a car alarm installation with auto start to succeed, you will need a multimeter (a device that measures the voltage level in an electric circuit and its resistance), pliers, scissors, a pair of Phillips and minus screwdrivers, and also several meters of wires.
Getting to work
Having prepared all the tools, you can safely get to work. But before embarking on a car alarm device, do-it-yourself installation begins with a complete blackout of the electrical circuit. To do this, remove the negative terminal from the battery. Next, you need to decide in which place the car alarm will be located. This device can be placed absolutely in any part of the car, however, it is important to ensure that this place is not exposed to frequent dust and moisture. It is advisable to install it not in hard to reach places. It is also worth considering where to place the car alarm sensors. Do-it-yourself installation should be carried out in those places where there is no radio or other devices nearby that create radio frequency interference. Do not forget about the sensitivity controls. On some models of the device they may not be adjusted, therefore, upon completion of work, check the sensors for sensitivity to shock.
Further, according to the electrical circuit and the car alarm device, a do-it-yourself installation is accompanied by connecting wires. We cannot give a specific scheme, since each device has its own connection points. When installing the lights, select which part of the optics you want to use - side lights or low beam headlights. Carefully monitor the polarity when connecting an alarm. As for the wires, they are connected by soldering or twisting to the standard terminals. Do not forget about isolation. This will protect you from a sudden electrical circuit of the car.
At the last stage, an audio siren is installed. It must be mounted in such a way that moisture does not get on it. It is installed under the hood, and where exactly - you can choose for yourself. By the way, the direction of the siren can also be configured yourself. Now it remains to reconnect the battery terminal and check the operation of the car alarm. DIY installation at this stage is completed.
