NOTE: In security applications, lead-acid batteries are generally used for
floating charging. It is recommended that the charging voltage of the
LAD should not exceed the floating charging voltage of the battery to
ensure that the battery under long-term use.

5.2. Buzzer mode selection 3
Fire alarm system：When the battery is under voltage, the buzzer will alarm.
Evacuation system: When the battery is under voltage, the battery is missing,
the battery is reversely connected, and the output is overloaded, the buzzer
will alarm.
