A modern shock sensor is a two-level device included in most security systems, designed to respond to external influences and promptly notify the car owner about them. However, sometimes the alarm system malfunctions.
Instructions
Step 1
Shock sensors are built on a two-level principle to separate true and false alarms. They have the ability to distinguish between weak and strong influences. The former will trigger a warning signal that the vehicle is armed, while the latter will trigger a full alarm cycle.
Step 2
When adjusting the shock sensor by simulating an external influence of a certain intensity, carry out a response control and, if necessary, change its sensitivity threshold.
Step 3
There are two ways to adjust the sensitivity of the shock sensor. The first is semi-automatic. Put the sensor in learning mode, and then simulate the impact on the car body. To do this, make light and strong blows to the body. The sensor's microprocessor will remember the information and will later use it to separate the shocks according to their intensity. This method has a significant drawback. When impacts of the same intensity, but produced on different parts of the car, the sensor can be triggered in different ways. If in the training mode you struck a weak blow on the wheel, then in the guard mode, the impact of the same force on the body can cause an alarm, and vice versa.
Step 4
The second tuning method is more time consuming, but gives better results. Put the sensor into the setting mode, then tap different parts of the car, evaluate the reaction of the security system as a whole and decide at what level of sensitivity you should stop. Adjust the warning and alarm zones separately. The first zone should be triggered by light blows, the second by strong ones.
Step 5
Change the sensitivity threshold of the sensor, depending on its type and design, by pressing a button, changing the position of the trimmer resistor or making changes to the system memory via the programming interface.
