This manual contains instructions
for the IRR-4S only. For specific
information on the adjustment
and operation of your Niles
Infrared system, please refer to
the instruction manual included
with your Niles Main System
Unit (IRP-2, IRP-6A, IRZ-6A).
Operation of the IRR-4S is sim-
ple. Aim your hand-held remote
at the IRR-4S. Your IR command
is instantly repeated to your A/V
equipment. A green "flash-back"
LED on the IRR-4S visually con-
firms remote control operation.
Troubleshooting
The "flash-back" LED on the front
of the IRR-4S is a useful trou-
bleshooting aid.
The LED should light only when
a remote command is being
received.
If the IRR-4S does not work, and
the LED does not light at all:
1. Test the remote control(s) by
operating the A/V equipment
directly. Replace the batteries if
needed.
2. Double check the cable con-
nections on all IRR-4S's and on
the Main System Unit. Look for
open, shorted or reversed wires.
If the IRR-4S does not work, and
the LED remains solidly lit:
1. Double check the cable con-
nections on all IRR-4S's and on
the Main System Unit. Look for
shorted or reversed wires.
2. Test for interference from the
following sources:
• Reduce the amount of sunlight
in the area of the IRR-4S.
• Turn off florescent, neon or
halogen lights in the room.
• Turn off light dimmers, begin-
ning with those closest to the
IRR-4S.
Observe the IRR-4S LED while
performing all the tests. It is pos-
sible to have interference from
more than one source.
There are many methods for
reducing interference. Which
solution is best for you depends
on your situation. Contact Niles
Technical Support at 1-800-289-
4434 if you require further assis-
tance.
If the LED on the IRR-4S "flickers"
dimly, and the IRR-4S functions
normally, there is no cause for
concern.
OPERATION
SPECIFICATIONS
The IRR-4S offers a number of
improvements over other in-wall
IR sensors.
• Universal system—compatible
with most brands of A/V equip-
ment and remotes using carrier
frequencies 26 to 60 kHz.
• Greater IR receiving range—18
to 30 feet of remote control
range instead of the typical 15 to
25 (depending upon the remote
control, actual range may vary).
• 100% factory tested for pickup
range and angle.
• Green "flash-back" L.E.D. visu-
ally confirms remote control
operation.
• Simple 3-wire hookup.
• Removable connector simpli-
fies installation.
• Mounting depth of 2 3/4" fits
into most standard 18 cubic.
inch 1-gang electrical boxes.
• Printed circuit board design
uses no hand wiring, assuring
high reliability.
• Ideal for both home and com-
mercial installations.
• Available colors: White, Bone,
Almond, or Black.
• Two year parts and labor
warranty.
• Proudly made in the USA.
FEATURES & BENEFITS
The IRR- 4S is a wall-mount,
infrared sensor which uses a
standard-style wall plate and is
designed for use with the Niles
Infrared Repeating and IR
Routing Systems.
Installed in a remote room loca-
tion, the IRR-4S receives the IR
commands transmitted from your
existing hand-held remotes in
that room. The commands are
carried via a small 2-conductor
shielded cable to your A/V
equipment in another room, and
instantly "repeated".
The IRR-4S is compatible with all
current Niles infrared systems. It
may be used along with, or as an
alternative to, the Niles IRR-4D,
SCW-UIR, TIR-1, MS-1, MS-2
and CMS-3 IR sensors.
The IRR-4S is just one of the three
building blocks necessary to com-
plete a Niles IR repeating system:
• Main System Unit — Models
IRZ-6A, IRP-6A or IRP-2.
• IR Sensors — Models IRR-4S,
IRR-4D, SCW-UIR, TIR-1, MS-1,
MS-2 and CMS-3.
• IR Flashers — Models IRC-1,
IRC-2, IRW-1 and IRW-2.
An expansion unit, Model
XRP-6A, is available for IR
repeater systems used in more
than six rooms.
