List 4 – Room names should be written below.
Controller corresponds to the room / zone number chosen for your
speakers. Each zone operates independently, so it is very important to
connect the keypad to the correct zone keypad input.

Zone 2 _________________
Zone 3 _________________
Zone 4 _________________
• On List 4 (opposite) copy down the room name to the zone number
from List 3 on pg 6. NOTE: the keypad and the speakers in each room
must be hooked to the corresponding numbered zone.
WIRING AT THE CONTROLLER
CLEAN INSTALLATIONS
CAi System keypads are wired with CAT-5 wire. It is inexpen-
sive and color coded for ease of installation. Due to the
qualities of CAT-5 wire, when using it for keypad control
wire with the CAi-Series, it is recommended to use the fol-
lowing color code for maximum performance. NOTE: 250ft
run of wire maximum per keypad is recommended.
For clean installations, we recommend using RJ-45 jumpers
to run from the CAi controller to an RJ-45 Wall Plate then
running your keypads from the Wall Plate.

INSTALLING KEYPADS
PUNCHDOWN TERMINALS
INSTALLING THE KEYPADS
Figure 11 – Punchdown
Terminal on CAi keypad
• The best infrared remote performance is achieved with
the keypad away from any direct sunlight. Also consider
convenience when choosing a location.
• Choose a place that is easily seen from the position where
a person is most likely to be located.
• Check whether or not you can route the wire to the loca-
tion you have chosen.
• Purchase retro-fit plastic junction boxes (min. 18 cubic
inches) or p-rings and cut in the boxes using a key-hole
saw or sheetrock knife/hand saw.
The CAi Keypads come with 110 punchdown terminals. These
terminals are quick, easy to install and provide a strong con-
nection. Punchdown terminals require the use of a punch-
down tool. One has been provided with this kit.
• If you are installing the optional DSC keypad you will
need to use a double-gang electrical box. If you are
installing both the optional DSC and DAN keypad you
will need to install a triple-gang electrical box.
Press wires into punchdown terminal with punchdown tool
as shown in Figure 12.
• If you feel uncomfortable cutting into your walls and
running wire through the walls, seek help from a profes-
sional installer or an electrician.
Figure 12 – Punching Down Wires
• Route the wire to the junction box from the CAi location.
• If using 22 AWG wire, connect each wire to the correct
position 1 thru 8 using the included punchdown tool.
Refer to List 5.
Punchdown
Tool
• If using CAT-5 wire, connect each wire to its correspon-
ding color labeled on the punchdown terminal.
• Mount the keypad in the junction box and attach the

KEYPAD WIRING PROTECTION CIRCUIT
ELIMINATION OF BALANCE LINE
To provide protection for incorrect keypad wiring, this CAi-
Series product is equipped with a short circuit protection
device. In the event of a keypad cable short, or incorrect
keypad wiring, this device will automatically interrupt power
to all keypad ports.
The following diagram shows how resistors may be used at
the Keypad connection on the rear of the CAi master control
unit, to provide 2.5VDC to the balance control line for cen-
tering. This circuit will stabilize the balance line input and
keep it centered. They can be used to free up one of the 8
required conductors if one is open, shorted or if an extra
conductor is needed for a secondary IR receiver’s signal in
that zone. Position #7 is GND, #2 is 12VDC, #4 is Balance.
Once installed, if the keypads connected to your CAi-Series
product will not turn on, the short circuit protection device
may have been activated. Please take the following steps to
troubleshoot the system.

Line Connections
1) Turn off the power switch on the front of the CAi-Series
controller.
2) Disconnect all keypad connections from the rear of the
controller.
3) Check the wiring configuration for each keypad, checking
both ends (the CAi unit and the CA keypads) of the CAT-5
keypad cable.
4) If incorrect connections were found, correct the wiring
and reconnect the keypads to the controller. After the
controller has been powered off for at least 15 seconds,
turn on the power switch of the CAi-Series controller.

TROUBLESHOOTING
COMBINING ADDITIONAL IR RECEIVERS
LINK
OUT
When combining a CAi Series multi-source controller and a
secondary IR system together, it needs to be done after the
CAi System. The IR information from the keypad is on Pin
#2. This signal is demodulated at the keypad and is re-mod-
ulated at the processor then sent to the emitter out-puts.
Combining a modulated IR signal to this lead (#2) will not
work because it is already modulated. The following method
should be used to assure correct integration with such com-
ponents.

IR RECEIVER
Simply plug the IR linking cable supplied with the CAi prod-
uct into the IR “Link Out” jack on the CAi and plug the other
end into the Russound 857 IR Connecting Block’s “IR
Common In”. The secondary IR receiver can either be wired
to the terminal block as shown or plugged into the “IR
Reciever In” via an 1/8” mini-plug. The emitters that would
have been connected directly to the CAi system will now be
plugged into the connecting block.
