350mA/700mA Battery
Charging Jumper
The 350mA/700mA Jumper allows you to
select the charging current for the backup
battery of the 2-Door Expansion Module.
Charging the battery at 350mA takes
longer, but consumes less power. Charging
the battery at 700mA takes less time, but
consumes more power.

Programming in Centaur
Using the Centaur Access Control Software,
program the inputs, outputs, readers, and
keypads connected to the 2-Door Expansion
Module. The options are explained in the
Centaur Access Control Software Reference
Manual
. Centaur will identify the 2-Door
Expansion Module by its address (defined by
the DIP Switches 1 & 2) and will recognize
the devices as follow:
