Monitoring of the Vehicle Battery

Monitoring of the Vehicle Battery
The emergency siren detects:
^ A drop in voltage from the vehicle battery due to a break in the wiring
^ A voltage > 17 V
^ A voltage drop from a value of 7.5 V to 6.5 V in less than 40 mins
The emergency siren monitors the B+, GND and DWA bus connection leads. If these leads are cut through, the independent alarm will be issued immediately.
In accordance with ECE regulations, the emergency siren will not issue an alarm if, as a result of the vehicle being immobile for a long time, the battery is being continually discharged and the vehicle electrical system voltage drops by 0.5 Wh to 3 V in the process.
