While a car alarm may look like a young boy’s science project, it is the very thing that could protect you, your family, and your vehicle from harm. Recent statistics show that in the United States alone, cars get broken into every 20 seconds. So if you want to ward off thieves, you better install the best car alarm in your vehicle.
But just in case you get curious about how do these things work, here is an overview of the basic car alarm parts. Let’s check out its common elements. In essence, all car alarms contain:
- Network of sensors
- Radio Receiver
- Auxiliary battery
- Control Unit
The control unit of the car alarm serves as its brain. It is the one that triggers the siren, closes and opens the switches, and activates all its other features. This computer control unit is wired to the car’s main battery, although it has a backup power of its own, which is the auxiliary battery. The auxiliary battery is important because it allows the car alarm to still work even if the thief has disconnected the car’s power sources.
Everything will be connected to the computer control unit. This means all the sensors, sirens, lights, and even the key code receiver will be controlled by it. The radio receiver, on the other hand, is the handy device that controls this main unit. It is what you use to enable or disable your car’s alarm system.
Some of the common devices attached to the main control unit are:
- Door sensor
- Interior pressure sensor
- Microphone sensor
- Mercury tilt and shock sensor
- Interior and exterior lights
- Keyless entry receiver
- Crossover units
All of these elements are interconnected to the main car alarm control unit that is placed under the hood of your car. A series of connecting wires will run from the control unit to each of these elements. When installed properly, the sensors will trigger the siren if and when certain conditions are met.
However, not all car sensors are the same. Some sensors are basic and quite easy to install. Others can be too complicated that it needs a professional to get them installed right. Either way, you have to choose the brand that suits the level of protection that you need. Some car alarm systems have auxiliary outputs, meaning you may still be able to add new features to it when those become available in the future.
Aside from installation, car alarm systems also require maintenance. It is very important that these systems are working perfectly day by day. Be sure that it is a part of your car’s routine checking process.
But while what we have described above is how most car alarms work, certain types may not be compatible with your vehicle at all. It is best that you consult with an expert when you buy a car alarm. The inputs of an expert will be crucial if you want a car alarm that can turn your vehicle into a fully secured automobile.
