It may be due to an issue with the wiring of the anti-theft device's main unit. Below is a related introduction to car alarms: Working Principle: When the sensor is struck or shaken, causing it to vibrate, a small ball inside the cylinder will roll. As it rolls away from a smaller secondary electrical contact, the circuit formed by this secondary contact and the central electrical contact will break. At this point, the switch opens, signaling the controller that the ball has moved. As the ball continues to roll past other secondary electrical contacts, the circuit will repeatedly close and open until the ball finally stops moving. System Composition: The most basic car alarm system typically consists of one or more sensors connected to an alarm. The simplest alarm system involves installing a switch on the driver's side door and connecting the wiring so that if someone opens the door, the alarm will sound. Installing such a car alarm system requires a switch, some wires, and an alarm. Most car alarm systems are far more complex than this.
