MANUEL D'INSTALLATION
CA-A470-A
2-Door expansion module
INTRODUCTION
Connected to the CT-V900-A controller's
expansion bus, Maximum 3 per controller,
the 2-Door Expansion Module (CA-A470-A)
supports two readers, two BCD keypads,
four zone inputs, 6 outputs and two locking
devices.
SPECIFICATIONS
Readers:
- connect 2 per module
Keypads:
- connect 2 per module
Inputs:
- 4 standard without ATZ,
- 1 tamper
Outputs:
- 6 (open collector) 50mA
Sink
Lock Outputs:
- 2 lock outputs
(Form C relays)
- each: 15A @ 28VDC
(resistive)
AC Power:
- 16VAC, 40VA max.
Frequency:
- 50Hz/60Hz
Aux. Current:
- 500mA (max.)
Battery:
- 12VDC, 7Ah
- low battery = 10.2VDC
- low battery restore =
12.2VDC
- low battery cut-off =
8.5VDC
Communication: - expansion bus (E-Bus),
RS-485, Plug and Play,
3 modules per CT-V900-A
Operating temp.: - 5
DIP Switches
In order for new DIP switch settings to take effect,
the 2-Door Expansion Module's power must be
disconnected and then reconnected.
Assign Address (1 and 2)
DIP switches 1 and 2 determine
the 2-Door Expansion Module's
address in the network, regardless
of the order that they are connected
to the controller. Centaur recognizes
the doors according to the DIP switch
settings as shown in Figure 1.

Lock State during Communication
Failure
o
F)
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.
Lock #1 = DIP switch 3
Lock #2 = DIP switch 4
