What is the reason for the red dot on the dashboard after locking the Buick Excelle?

[McAdriel]

After locking the Buick Excelle, a red dot on the dashboard indicates that the vehicle has entered the anti-theft state, and the anti-theft system is functioning normally. It utilizes mobile communication networks to overcome the distance limitations and vulnerability to cracking that ordinary anti-theft systems cannot resolve. In addition to the functions of a standard anti-theft system, it also features mobile phone control, SMS positioning, remote monitoring, remote alarm, and full voice prompt operation. The electronic car anti-theft device contains an integrated chip. When an external trigger voltage is applied, the switch opens and outputs a positive voltage to the driving circuit, which then activates the actuator and alarm circuit. The external voltage is applied via sensors or switches, ensuring concealment and resistance to tampering.
