Car Alarm Installation

Admin — Tue, 09 Jun 2009 05:25:34 +0000

The installation of a car alarm can be quite interesting and one can successfully do it without any professional assistance. To do this a number of equipment should be present such as a knife, soldier material, screws, test light, scissors, drill tie wrap, ***** bit, mounting tape which is double sided, voltage meter and a soldiering meter. Most important however, is the installation manual which gives a guideline on how to assemble each component of the car alarm. Therefore, caution should be taken to ensure that what is being done is per the manual direction which usually comes with the car alarm.

This is because there are a variety of car models and in most instances each of these models has its own unique lock and door and hence the need for a help line from the manufacturer arises. Aside from the manual, there should be a contact reference which one can use to question the type of locking system a car has. One can also confirm the connection details of the wires according to the colors so that the interface suits the alarm’s locking characteristics. Installation details of the relay which is meant for the door lock and wire color for the starter disable should be clearly understood .It is also important for installer to be well aware on how to hook the relay up and use the voltmeter set up whose sole purpose is to test the door lock wires for the car.

The first step of the car alarm installation calls for ensuring that the segment system is working as it was intended to. The siren should be mounted on a solid metal surface right under the hood. After this is done, point the siren horn towards the ground to prevent moisture from collecting from within. A hole is then drilled by a gommet made of rubber in the car firewall and then the siren wire is passed into the hole to the car’s passenger compartment. After that the alarm power should be connected directly to the car battery and a fuse put on the power wire which resides beside the battery. The installer should take note of the fuse size which is indicated on the installation manual and mount shock sensors. Once this is done, a hole is drilled in the dash board, where the LED status is indicated and the LED wire passed through it. Thereafter, place a double sided mounting side from the LED’s back which should then be placed on the dash hole.

The installer should then locate the wires which are responsible for making the power door locks work and connect them to lock or unlock wires and the alarm wire according to the technician advice. Find the wire that enables the courtesy light to turn on should the alarm have current sensing then connect it to the alarm. If the alarm lacks voltage sensing, find the factory door triggers and connect it to the alarm. The steering column under the starters should then be cut and the starter disable relay connected. Having completed this, the valet should be mounted below the dash then ensure the output and input alarm module connections have been done well .Finally mount the module on a sturdy surface then ***** it. Tie wraps will help secure harness wires .The alarm should then be armed to test if it is performing well. With do-it-yourself tips on how to install a car alarm, installation is quite an easy task.

Car Alarm Systems

Admin — Sat, 06 Jun 2009 07:41:48 +0000

Car alarms are usually the only thing that can keep your car safe. They are made to alarm you and everyone in range for possible stealing attempt.

We will go over the most frequently used car alarm systems and how in fact they work. To begin let’s see one basic system. It needs only three components – siren, wiring and a door sensor. This sensor is made to put the siren on if the door is open. It is made by a simple switch that is pushed by the door. When the door opens – the switch sets the wiring and the siren goes on. This is not a good way of making an alarm because when you get into the car the siren will go on and you will have to disable it manually. This is usually done via another switch. It has to be hidden and like that only you will be able to shut it off when you get into the car.

When we want to make a system that is more advanced we use the same components but we add some new. These components are in fact sensors and now I will tell you about some of the sensors that are used.

The shock sensor is used to supervise motions and vibrations. It sends different signals to the operational computer depending on the intensity of the motion or vibration. For example if someone knocks on the window of your car a signal for low intensive vibration will be sent to the computer and it will make the siren beep once. This will warn the thief that the car alarm is armed and will respond to possible assault. If someone tries to break the window the sensor will signal the computer and a full-scaled alarm will go on.

The pressure sensor is another good part of the advanced car alarm systems. It can detect both breaking or opened window and open door. This is done by measuring the air stressing intensity.

Another good way for protection is tilt/motion sensor. This is important because the thief can get parts from your car even without opening window or door. For example he can easily lift up your car. This will give him a way to steal parts without setting the alarm. To prevent this some alarms uses scanning devices that can tell if someone gets close to the car. This is usually done by radar system that checks the signal reflection immediately close to the car.

And in the end I want to tell you about one very interesting solution. This is a message that is recorded and played instead of a beep. It’s a simple warning that tells the intruder that the alarm is armed. The funny part is that in some level the thief will react like if the system is in fact intelligent. This happens because of the human brain that reacts to the voice. Even when the thief knows that it’s only a system an unconscious warning will still be there to tell him that something could go wrong.

Some people buy either directly from a dealer, purchase from a shop or via internet transactions. There are many kinds of alarms for your car and different brand names as well. In order to differentiate which car alarm is of good quality, check its wiring harness. The thicker the wire, the better. This is due to the fact that it can withstand the electrical current. Low quality car alarms use very thin wiring.

Look at the diagram of the wiring. Most good quality car alarms use the same color coding. This is while car alarms of low quality use a different one. The idea of a universal color system makes an experienced installer install a car alarm in no time. If the color coding is different, the installer can have a hard and long time installing the car alarm. This can also waste precious time and money if ever the installer charges his services by the hour.

Below is a list of how the wiring must be coded.

The “RED” wire is equal to 12+ Positive

The “BLACK” wire is equal to Negative Ground

The “WHITE” wire is equal to Parking Lights

The “BROWN” wire is equal to Siren

The “BLUE” wire is equal to Shock Sensor or Sensor Input

The “ORANGE” wire is equal to Negative when Armed

The “VIOLET” wire is equal to Door Lock

The “PURPLE” wire is equal to Door Lock
