2-Door Expansion Module
DIP switches 1 and 2 determine the 2-Door
Expansion Module’s address in the network,

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.
Access is denied to all cards and doors
are locked until communication is restored.

Access is granted only when 2 cards of
a valid format are presented to the reader.

Access is granted when any card with
a valid format is presented to the reader.

Activate Output on Communication Failure (7)
DIP switch 7 determines if OUT5 and OUT6 will
pulse during a communication failure. When DIP
switch 7 placed in the ON position, the outputs on
the device(s) connected to the OUT5 and OUT6
terminals will pulse. For example, the LED on
the reader can pulse to advise users that a
communication failure has occurred.
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.
Introduction
Connected to the CT-V900 controller’s expansion bus, the
2-Door Expansion Module (CA-A470-A) supports two
readers, two BCD keypads, four zone inputs, 6 outputs
and two locking devices.
Centaur will identify the 2-Door Expansion Module by its
address (see DIP Switches 1 to 4) and will recognize the
devices as follows:

Specifications
CA-A470-A Specifications:
Place the EOL jumper ON if the 2-Door Expansion Module
is at the beginning (Start Point) or at the end (End Point) of
the E-bus Network (see Figure 2). Otherwise, place the
Lock State during Communication Failure
DIP switches 3 and 4 determine the state of
Lock #1 and Lock #2 ONLY during a
communication failure between the 2-Door
Expansion Module and the controller (CT-V900-
A). Normally, the lock outputs follow the Lock
Control for the CT-V900-A. Therefore, the DIP
switches should have the same setting as the Lock
Control for the corresponding doors in Centaur.

During a communication failure, the normal state of
the lock output is De-energized. When Lock #1 or
Lock #2 is activated, power is applied to the
corresponding lock output to unlock the door.
Activation depends on the setting of the DIP switches
5 & 6 (Access during Communication Failure).

Energized:
During a communication failure, the normal state of
the lock output is Energized. When Lock #1 or Lock
#2 is activated, power is removed from the
corresponding lock output to unlock the door.
Activation depends on the setting of the DIP switches
5 & 6 (Access during Communication Failure).

In order for new DIP switch settings to take effect,
Expansion Module is at the beginning (Start Point) of the
E-bus Network. Otherwise, place the A+ and B- jumpers
on HIGH (see Figure 2 and Figure 3).
the 2-Door Expansion Module’s power must be
disconnected and then reconnected.
Other modules in the system cannot activate the 2-
Door Expansion Module’s outputs.
De-energized: no power in normal state; requires
power to activate.
The 2-Door Expansion Module does not support
Zone Doubling (see Figure 6).
Energized: power in normal state; remove power
to activate.
