Due to the built-in battery, the siren has a special mode that will add even more security to a car. If an attacker disconnect the power supply of the siren while the system is armed, the siren will start screaming to notify an owner about the attempted theft. The siren also has reliable charging algorithms that fulfill the EU regulations. The siren starts charging the battery only when the engine is running.
The “Control of Bluetooth connection with a main unit” function is also present in the new siren. This function protects against disconnecting power supply of a main unit. Therefore, if someone disconnects the main unit, the siren will also notify an owner by the loud sound.
