BB-02 Backup battery

The BB-02 is a back-up battery equipped with its own electronics for taking control of the power supply. It is intended for use with the CA- 1803 and CA-1802 car alarms.

Backup battery

BB-02 Backup battery

During normal operation the BB-02 is supplied (or charged) by the car alarm power supply. If the voltage drops under 8.5V, the BB- 02 starts to generate a voltage. Except for the acoustic siren, the BB-02 backs up all the functions of the car alarm. This also includes voice communication if an HF-03 handsfree set is attached. The back-up voltage is generated either for the duration of the car voltage supply outage or until the BB-02 is completely discharged.
