MS-100

MS-100
INTRODUCTION
FEATURES AND BENEFITS
The MS100 is a flush-mount IR sensor designed
for use with the Niles infrared extender systems.
The MS100 offers a number of improvements
over other miniature IR sensors.
Installed in a remote room location, the MS100
receives the IR commands transmitted from your
existing hand-held remotes in that room. The
commands are carried via a category 5 cable to
your A/V equipment in another room, and
instantly “repeated”.
• Plasma-proof performance—allows placement
of the MS100 near plasma displays.
The MS100 is compatible with all current Niles
infrared systems. It may be used along with, or as
an alternative to, the Niles TS100, WS100, MS200,
MVC100IR and CS100 sensors or the IntelliPad®.
The MS100 is just one part of the three building
blocks necessary to complete a Niles IR repeating system:
• IR Main System Unit—Models MSU140,
MSU250, MSU480 and MSU440Z.
• IR Sensors/Keypads—Models WS100, TS100,
MS100, MS200, CS100, MVC100IR and the
IntelliPad.
• IR Flashers—Models MF1, MF1VF, MF2,
MF2VF and the IRB1.
An IR sensor expansion hub, Model IRH610, is
available to provide additional sensor inputs to
your system.
• CFL interference resistant—expands installation
flexibility to areas with fluorescent lighting.
• Works under most lighting conditions, including indirect sunlight—eliminates environmental restrictions.
• Universal system—compatible with virtually all
brands of A/V equipment and remote controls.
• Excellent IR receiving range—you get 18' to
30' of remote control range (depending upon
the strength of your handheld remote).
• 100% factory tested for pickup range and
angle.
• Small size of only 1/2" diameter by 2-5/16"
long—fits almost anywhere.
• 10' connecting cable included.
• Printed circuit board design uses surface mount
technology (SMT), assuring high reliability.
• Ideal for both home and commercial installations.
• Bezel colors: Each MS100 includes a black and
white bezel.
• Two year parts and labor warranty.
INSTALLATION CONSIDERATIONS
Type of Cable
The MS100 connects to the Niles infrared main
systems unit or IRH610 sensor expansion hub
with an individual home run of category 5 cable.
When running wires inside walls, most states and
municipalities in the U.S. specify that you must
use a special type of wire. Usually, the requirement is that the wire has a specific “CL” fire rating, such as “CL-2” or “CL-3”. Consult your Niles
dealer, building contractor, or local building and
inspection department if unsure about which type
of wire is best for your application.
The MS100 is designed to flush-mount almost
anywhere. Convenient mounting locations for
the MS100 are:
• In a cabinet door
• In a wall, or wall-plate

MS100 Mounting Location
The MS100 is ideal for use in applications when
tabletop, ceiling, or wall-mounting is undesirable. Its small size and unobtrusive appearance
makes it ideal for installation in obscure, hidden
locations, in cabinet facings, or in the sensor
knockout built into Niles in-wall loudspeakers.
Installing the MS100 close to the primary location of the user will ensure best performance.
• Behind a speaker grille.*

Receiving Range and Pickup Angle
The receiving range of the MS100 will vary
according to the IR output strength of the remote
control being used. Remote strength varies
among brands depending on the number and
size of batteries used, and how many IR emitters
the remote has. For example, remotes that operate on two small AAA batteries and have only
one IR emitter are generally not as strong as
remotes that use the larger AA size batteries and
have two emitters. Tests with various manufac6
“Tech Tip”
Do not install the MS100 next to a light dimmer.
The IR pickup angle of the MS100 is 30° off-axis
(horizontal and vertical) at 20'.
Avoiding Electrical Interference
Avoid locating the MS100 near any potential
sources of electrical or optical noise, such as
light dimmers, low-voltage lights, and
neon lights.
Do not install the MS100 into electrical
boxes with 110 volt devices.
Some states or municipalities allow devices
such as the MS100 to be installed into the
same electrical box as 110 volt devices, provided a “low-voltage partition” is used
between the devices. We do not recommend
this. The cable connected to the MS100 can act
as an “antenna” for electrical noise. Locating
the MS100 cable too close to a light dimmer or
switch may interfere with the MS100. If you
must locate the MS100 near electrical devices,
install it in a separate metal electrical box,
ground the box to the electrical system ground,
and route the MS100 cable several feet away
from all electrical wiring.
Infrared signals travel essentially line-of-sight.
They will not pass through or around solid
objects. Do not rely on an IR signal being able to
“bounce” off a wall or object to the MS100.
Avoiding Optical Feedback
If installing the MS100 in the same room as an
IR flasher, it is possible for the flasher’s IR output
to be picked-up by the MS100. This effect,
known as an optical feedback loop, can cause
erratic operation. Optical feedback is similar to
acoustical feedback: the howling or whistling
sound heard in a P.A. system when the microphone is too close to the speaker.

turers’ remote controls have shown that the
operating range can vary from a minimum of
18' to a maximum of about 30'.

INSTALLATION & OPERATION GUIDE
To avoid optical feedback:
1. Re-position the flasher(s) and/or the sensor.
2. Use Niles MF1 or MF2 flashers and cover them
with the supplied IR blockers.
Changing the Color of the MS100
The bezel surrounding the lens on the MS100 is
removable, allowing fast and easy color changes as
needed. A black and white bezel are included with
your MS100. If you desire, you may paint the
MS100 bezel yourself—to blend it seamlessly into
your decor.

smooth side of the socket. Don’t force the
scalloped side of the connector plug into the
smooth side of the socket.
1. Determine a mounting location for the
MS100. Select a location where you will have
access to the rear of the MS100 after it is
installed. This will allow you to securely tighten
the MS100 to the mounting surface using the
supplied hardware.
6. Secure the MS100 by tightening the hex nut.
DO NOT OVER-TIGHTEN.
2. Drill a 1/2" hole where the MS100 will
be mounted.
If you need to change the bezel of the MS100:
1. Hold the MS100 so that the front of it is facing you. Unscrew the bezel by turning it
counter-clockwise as shown in Figure 4.
Note: The MS100’s lens is held in place by
the bezel—be careful not to lose it.
2. Hold the MS100 so that the front of it is
facing you, making sure that the lens is in
place. Screw the new bezel onto the MS100
by turning it clockwise.

Using the MS100 with the
Intellipad Ci system.
The MS100 is fully compatible with the Niles
Intellipad Ci line, follow the wiring instructions in
Figure 2. For specific information see your
Intellipad Ci manual.
3. Run the MS100’s IR cable. Label the cable
for future reference. The MS100 is supplied
with 10' of pre-stripped IR cable. The IR
cable may be shortened or lengthened as
needed. If you want to make the MS100’s
cable shorter, use a pair of wire cutters to cut
the cable to the desired length. The IR cable
may be lengthened by splicing it to a recommended IR cable (See Installation
Considerations—Type of Cable). You may
splice the MS100 cable to another cable by
soldering or crimping the connections.

OPERATION
Operation of the MS100 is straightforward.
Simply aim your hand-held remote at the
MS100. Your IR command is instantly repeated
to your A/V equipment.
TROUBLESHOOTING
This manual contains instructions for the
MS100 only. For specific information on the
adjustment and operation of your Niles infrared
extender system, please refer to the instruction
manual included with your Niles IR main system unit (MSU140, MSU250, MSU480
MSU440Z, IntelliControl).
1. Test the remote control(s) by operating the A/V
equipment directly. Replace the batteries if
needed.
2. Double check the cable connections on the
MS100 and on the main system unit. Look for
open, shorted or reversed wires.
3. Test for interference from the following sources:
• Neon or halogen lights in the room
• Light dimmers, beginning with those closest
to the MS100
11
Observe the main system unit IR confirmation
LED while performing all the tests. It is possible
to have interference from more than one source.
Eliminating optical feedback
In some installations, two conditions combine to
create an optical feedback loop. Symptoms can
include: poor range, intermittent operation or no
operation.
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 assistance.
