Bosch BCM‑0000‑B Battery Controller Module monitors the power supply of the fire panel and the charging of the batteries

The BCM-0000-B Battery Controller Module monitors the power supply of the entire control panel. It controls the charging of up to four batteries (12 V/24 Ah to 12 V/26 Ah or 12 V/36 Ah to 12 V/45 Ah). The charging is actuated by temperature and time. The key has three functions, depending on the state of the battery controller module: the LED test of the module is activated by pushing the key; the key starts the charging of the batteries if the battery voltage is between 18 V and 21 V. A mains power supply is required; the reset of the 24 V outputs. If an error occurs, the output is deactivated.
