25) Bad Connections at the IRP6+
and/or at the Sensor/Keypad.
Verify that all connections are good
both at the IRP6+ Sensor Inputs and
at the remote sensor/keypad. Check
that the jacket of each conductor has
been properly stripped and inserted
into the connector. Examine the con-
nectors for a hair-like filament of wire
between any of the contacts. Repair
as necessary. Retest the system(have

26) Test Cable for Shorts
Disconnect the cable at both ends
(at the sensor and at the IRP6+) and
test it for shorts. Use an ohm meter
or electrical continuity checker. You
should read an open (Infinite Ohms)
between Red and Bare, Red and
Black or Bare and Black. If you find a
short, replace or repair the cable as
necessary. Retest the system(Have
someone watch the green IR LED on

27) Test Cable for Opens
At one end of the cable, twist the
exposed copper ends of the Red (+)
and the bare (GND) conductors
together. At the other end of the
cable, use an Ohm meter or continu-
ity checker to check for a break in the
cable. You should read a short (zero
ohms) between the exposed copper
ends of the Red (+) and the bare
(GND) conductors. Repeat this test
with the Red (+) and the Black
(DATA) conductors. If you find an
open, replace or repair the cable as
necessary. Retest the system (have
someone watch the green IR LED on

35) Test for Shorts
A) Verify that all connections at the
IRP6+ are correct. Look for a hair-like
filament of wire between the two
contacts.
B) Verify that the sensor/keypad con-
nections are correct. Look for a hair-
like filament of wire between the two
contacts.
C) Disconnect the sensor/keypad
cable at both ends and test the cable
itself for shorts. Use an ohm meter or
electrical continuity checker. You
should read an open (Infinite Ohms)
between Red and Bare, Red and
Black or Bare and Black. After testing
all connections and cable, observe
the IR test LED.
• IR Test LED is Onor Flickering:
Go to Step 38
• IR Test LED is Off: Congratulations
36) Test for Optical Interference
Reconnect the problematic
sensor/keypad to the IRP6+. Cover up
the Sensor with a piece of cardboard
(your hand will actually create elec-
tromagnetic interference under some
conditions). Observe the IR test LED.
• IR Test LED On or Flickering: Go
to 37
• IR Test LED Off: Go to 36
37) Optical Interference
Identify the source of the interfer-
ence. The most common sources of
optical interference are listed in the
order of their probability:
Troubleshooting Guide continued
A) Sunlight. Reflections from win-
dows, mirrors, swimming pools,
shiny floors or objects.
B)Fluorescent light fixtures.
C) Neon signs.
D) A malfunctioning IR Remote
Control.
E) A malfunctioning Infrared Motion
Detector on your Security system.
Either re-orient the sensor or move
the source of interference. Niles
infrared sensors have built-in filters to
attenuate the effect of visible light. If
you add additional filtration you will
reduce the effectiveness of the sys-
tem with remote controls as well as
the interference.
If you are using the MS-1 or the MS-2
miniature sensors consider exchang-
ing them for IRR-4D, TIR-1 or the
CMS-3 ceiling sensor. These three
sensors have AGC circuits which
serve as automatic filters.
If you choose to attempt to filter an
MS-1 or MS-2, try a temporary mate-
rial (e.g. a single thickness of facial
tissue) and test whether filtration will
solve the interference and still give
acceptable range.
38) Electromagnetic Interference
(EMI)
Identify the source of the interfer-
ence. The most common sources of
electromagnetic interference are list-
ed in the order of their probability:
A) Televisions (particularly large
direct view sets).
B) Wall-mounted light dimmers or
variable speed controls for ceiling
fans. These controls emit more inter-
ference when turned down halfway.
They emit little or no interference
when turned up all the way (bright-
est position).
C) Fluorescent lights (the electronic
ballast sometimes emits EMI)
D) Large appliances (air-conditioners,
pumps, motors, compressors etc.)
E) AC line noise (noisebrought into
the system via the wall outlet con-
nected tothe IRP6+) Identify the EMI
source by turning potential sources
on and off (or fully up and fully
down) and watching for any change
in the IR Test LED on your IRP6+.
Once you have identified the source
of interference:
1) Move the sensor or the sensor
cable away from the EMI source
or move the source of the EMI
away from the sensor or the cable.
2) Shield the sensor with a metal J-
Box.
3) Connect the Sensor’s GND termi-
nal to true earth ground (if this
isn’t feasible use the IRP6+ GND
terminal).
4) Place a ferrite ring around the
cable creating the interference.
Ferrite rings can be purchased
from an electronic supply store.
Troubleshooting Guide continued
By adding an IntelliPad™to your
IRP6+ Infrared Extender System you
will add a remarkable level of conve-
nience to your system. The IntelliPad
is the world’s first programmable,
wall-mounted keypad system that
provides a unique LED power status
display and the convenience of true
one-touch remote control of com-
plex audio/video systems.
The IntelliPad’s status feedback fea-
ture eliminates the guesswork com-
mon with standard IR control sys-
tems. The power LED on the
IntelliPad indicates the On/Off condi-
tion of the system’s preamp/receiver.
Built-in intelligence tracks the On/Off
condition of the preamp/receiver so
the IntelliPad knows when it’s appro-
priate to issue the power command,
even when the user doesn’t. The sys-
tem maintains perfect synchroniza-
tion between the amplifier and the
user.
By combining an optional Niles 12v
DC power supply with your IRP6+
you can send a status signal to an
IntelliPad without running any addi-
tional wiring. Built into the IRP6+ is a
Niles Status Signal Generator. When
the IRP6+ sees 12v DC at the status
jack it broadcasts a Status signal over
your existing IR sensor wires. Any
IntelliPad connected to one of your
sensor wires will display power status.
IMPORTANT: For the IntelliPad’s
status feedback feature to work,
the pre-amp/receiver controlling
your system should have a
switched AC outlet, a switched
outlet is a 120v AC outlet that
switches off,when the preamp/
receiver is off and switches on
when it is on.
