INSTALLATION MANUAL
CAA460P - CAA460PNB
Relay Expansion Module
The CAA460P Relay Expansion module
provides an additional seven
to the CT-V900-A controller. Up to two
"plug and play" relay expansion modules
can be added to each controller for a
total of 16 relays per controller. The relay
expansion modules
to the controller via a RS-485 E-bus
network, allowing you to install the relay
expansion modules a maximum distance
of 1220m (4000 ft.) from the controller.
The module features an activation status
LED for each relay, a communication failure
LED with an associated output, a 24-hour
anti-tamper input and supply monito-
ring. Removable terminals are optional.

1] INSTALLATION INSTRUCTIONS

The E-bus is a RS-485 bus that allows you
to connect the relay expansion modules at a
maximum distance of 1220m (4000 ft.) from
the controller using
grade 3 cable or
connects to the CT- V900-A controller through its
on-board terminals. For a description of the module's
terminals, see "Terminal Overview". The following
details both the single
installation types.
CONNECTING A SINGLE CAA460P MODULE
Connect the A and B terminals on the CAA460P module
to the A2+ and B2- terminals on the CT-V900-A
controller. Then, connect the + and - terminals on
the CAA460P module to the +12V and GND terminals
on the CT-V900-A controller. See Figure 1.
As an alternate connection type, a 4-pin serial
connector (not included) can be installed between
the E-Bus connectors on the CAA460P module and
the CT-V900-A controller. See Figure 2. This installation
method can only be used when connecting a single
CAA460P module.
CONNECTING MULTIPLE CAA460P MODULES
When installing a
connect the A and B terminals on the second
CAA460P module to the A and B terminals on
the fi rst CAA460P module.

equivalent. The CAA460P
and multiple module
second CAA460P module,
The fi rst CAA460P
is connected to the
described in "Connecting a Single CAA460P Module".
Then, connect the + and - terminals on the second
CAA460P module to the + and - terminals on the fi rst
CAA460P module. See Figure 1.
