INSTALLATION CONSIDERATIONS
Type of Cable
The MS110 connects to the Niles infrared main
systems unit or IRH610 sensor expansion hub
with an individual home run of CAT 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.
MS110 Mounting Location
The MS110 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
MS110 close to the primary location of the user
will ensure best performance.
The MS110 is designed to flush-mount almost
anywhere. Convenient mounting locations for the
MS110 are:
• In a cabinet door
• In a wall, or wall-plate
• Behind a speaker grille.*
NOTE: Some types of speaker grilles will reduce the
IR pickup range of the MS110. If unsure, test
the pickup range before permanently installing the
MS110 behind the speaker grille.

We do not recommend this. The cable connected
to the MS110 can act as an “antenna” for
electrical noise. Locating the MS110 cable too
close to a light dimmer or switch may interfere
with the MS110. If you must locate the MS110
near electrical devices, install it in a separate
metal electrical box, ground the box to the
electrical system ground, and route the MS110
cable several feet away from all electrical wiring.
Avoiding Optical Feedback
If installing the MS110 in the same room as an IR
flasher, it is possible for the flasher’s IR output to
be picked-up by the MS110. 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.
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.
Using the MS110 with the Intellipad Ci System
The MS110 is fully compatible with the Niles
Intellipad Ci line, follow the wiring instructions
in
Figure 2. For specific information see your
Intellipad Ci manual.
Receiving Range and Pickup Angle
The receiving range of the MS110 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 manufacturers’ remote
controls have shown that the operating range
can vary from a minimum of 20’ to a maximum
of about 75’.
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 MS110.
The IR pickup angle of the MS110 is 60° off-axis
(horizontal and vertical) at 20’.
Avoiding Electrical Interference
Avoid locating the MS110 near any potential
sources of electrical or optical noise, such as light
dimmers, low-voltage lights, and neon lights.
Do not install the MS110 into electrical boxes
with 110 volt devices
Some states or municipalities allow devices
such as the MS110 to be installed into the same
electrical box as 110 volt devices, provided a “low-
voltage partition” is used between the devices.

FEATURES & BENEFITS
The MS110 offers a number of improvements over
other miniature IR sensors.
• Plasma and LCD-proof performance—allows
placement of the MS110 near plasma or LCD
displays
• 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 — 20’ to 35’ 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 2-7/8”
long—fits almost anywhere
• 10’ connecting cable included
• Printed circuit board design uses surface mount
technology, assuring high reliability
• Ideal for both home and commercial installations
• Two year parts and labor warranty
INTRODUCTION
The MS110 is a flush-mount IR sensor designed for
use with the Niles infrared extender systems.
Installed in a remote room location, the MS110
receives the IR commands transmitted from your
existing hand-held remotes in that room. The
commands are carried via a CAT 5 cable to your
A/V equipment in another room, and instantly
“repeated”.
The MS110 is compatible with all current Niles
infrared systems. It may be used along with, or as
an alternative to, the Niles TS110, WS110R, MS210
and CS110 sensors or the IntelliPad
® .
The MS110 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 WS110R, TS110,
MS110, MS210, CS110, 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.
IMPORTANT: Refer installation to a professional
custom installer if you are unfamiliar with any of
the following procedures.
