The alarm detects sudden voltage drops of the battery when the interior, trunk, or hood lights are switched on. 
To ensure correct operation, a number of control indications have been included, such as : flashing LED to 
indicate that the alarm is in standby mode after a set time (after you have left the car). Pre-alarm (built-in 
buzzer) to indicate that the alarm is activated, so that you will not forget to switch it off. The alarm is easy to 
switch on and off, either automatically or by means of the ignition switch or a remote control unit, such as the 

K8059 / K8057 or VM109.
