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
Green "lock#1" and "lock#2" LEDs:
ON = Relay activated.

Doors cannot be defined as Door
Type Elevator (Door Properties
window, General tab, Door Type:
Elevator) and the module does
not support Interlock Inputs (Door
Properties window, Inputs and
outputs tab, Interlock Input).
Other modules in the system cannot
activate the 2-Door Expansion
Module's outputs. The 2-Door
Expansion Module does not support
Zone Doubling (see Figure 6).
