Note 1: The XC10 provides the EN54-2 option with requirement 8.4 called “Total loss of power”. This option when selected activates the
system fault LED and the buzzer continuously, for at least 1 hour after a low discharge battery disconnection. The option can be
selected by wiring the +BAT terminal to the positive voltage of batteries (use of remaining power after battery disconnection).
