IR Considerations
Avoid locating any of the cables, sensors, or keypads near any potential sources of ElectroMagnetic Interference
(EMI) such as light dimmers, speed controls for ceiling fans, electrical ballasts, television sets, large motors,
heaters, or air conditioners.
Each room must be home run (wired directly) to its assigned sensor input. Recommended cables are "data grade"
cables made of twenty-two gauge or larger conductors surrounded by a foil shield and a bare ground wire.
Twenty-two to sixteen gauge shielded cable with a drain wire will accommodate 150 to 600 foot runs to each
sensor. CAT 5 is acceptable.
Reception range depends on the device being controlled and the levels of IR or EMI present.
The remote should be held vertical and with no more than 45 degrees off axis for nominal reception angle.
Be aware that different types of equipment have different latencies. Latency is an apparent delay between when
the command is issued and the unit responds. Some equipment may appear to respond faster than others and this
is normal.
Keypads generally use one of two types of signal transmittal - either current driven or voltage driven, meaning
that the actual data is conveyed as either a current pulse or voltage pulse traveling down the wire. Each method
has advantages and disadvantages, but to be compatible with as many different set-ups as possible, the A6600
comes with a set of 82-ohm resistors. These should be inserted between INPUT and GROUND signal lines at the
Euro connector if the keypad you are using seems to be malfunctioning. This will compensate for line variances
from method to method.
One keypad can be combined with one IR sensor within the same room. Do not use more than one receiver in a
room. If more than one receiver picks up the same signal, the A6600 may not respond.
Connection
Most Infrared receivers use a 4-screw terminal block. Follow the connections supplied with the instruction manu-
al of the unit. Keypads with built in IR pass-thru usually have the IR receiver connected internally. See KEYPAD
section for details. If your unit only uses three wires, either connect the status and +12VDC wires together at the
keypad or leave the status wire disconnected at both ends of the cable.
The IR/Keypad wiring is pulled down to the A6600 and connects to the supplied Euro connector detailed in the
KEYPAD section.
NOTE: Some installations may require use of the supplied 82-OHM resistor for reliable reception. See section
above and "Understanding Keypads".
Flashers/Emitters
The ARIA A6600 has seven IR emitter outputs located on the rear panel: Zone 1, Zone 2, Zone 3, Zone 4, Zone 5,
Zone 6 and Common. The Zone 1-6 outputs provide IR signal output from their respective zones, while the
Common output provides IR signal output from all zones. The Common output would most likely be used to con-
trol source equipment needed by every zone, such as CD players etc. The Zone 1-6 outputs are used to control
equipment that is proprietary to a particular zone.
Place the emitter/flasher over the receiver window on the equipment to be controlled, and insert the jack into the
Zone Output plug corresponding to the location where zone control is desired.
