INTRODUCTION
The Niles WS110R is a wall-mount, Decora® style IR sensor designed for use with the Niles infrared
extender systems.
Installed in a remote room location, the WS110R 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 WS110R is compatible with all current Niles infrared systems. It may be used along with, or as
an alternative to, the Niles TS110, MS110, MS210, and CS110 sensors or the IntelliPad®.
The WS110R 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, MF2, MF1VF, MF2VF and the IRB1.
An IR sensor expansion hub, Model IRH610, is available to provide additional sensor inputs to your
system.

FEATURES AND BENEFITS
The WS110R offers a number of improvements over other wall-mount IR sensors.
• Plasma and LCD-proof performance— allows placement of the WS110R near plasma and
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— you get 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 2-3/4” wide by 4-1/2” high by 1-1/4” deep — fits in a one-gang box
• Printed circuit board design uses surface mount technology (SMT), assuring high reliability
• Ideal for both home and commercial installations
• Removable Decora-style snap-in color insert (Available in four colors)
• Two year parts and labor warranty

INSTALLATION CONSIDERATIONS
The WS110R is a Decora-style module and is designed to use standard Decora-style cover plates
and mounting hardware. Decora cover plates (up to 6-gang) with color-matched plate screws are
available from your Niles dealer.
TOOLS REQUIRED
• 1/8” Standard Slotted Screwdriver
• 1/4” Standard Slotted Screwdriver
• Wire Stripper
TYPE OF CABLE
The WS110R 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.
WS110R MOUNTING LOCATION
Locating the WS110R in the center of a room usually results in the most even IR receiving coverage,
especially if the room is square shaped. Rooms that are L-shaped or long and narrow require more
careful consideration. With these types of rooms, installing the WS110R closest to the primary
location of the user will ensure the best performance.

INSTALLATION CONSIDERATIONS (CONTINUED)
RECEIVING RANGE AND PICKUP ANGLE
The receiving range of the WS110R 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 35’.
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 WS110R. The IR pickup
angle of the WS110R is 60° off-axis (horizontal and vertical) at 20’.
JUNCTION BOXES
The mounting depth of the WS110R is 1-1/4”. When installed, the unit extends 3/4” behind the
sheetrock wall (assuming 1/2” sheetrock). Suitable electrical boxes are available from your Niles
dealer or local electrical supply company.
DO NOT INSTALL THE WS110R INTO ELECTRICAL BOXES WITH 110 VOLT DEVICES.
Some states or municipalities allow devices such as the WS110R 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 WS110R can act as an “antenna” for
electrical noise. Locating the WS110R cable too close to a light dimmer or switch may interfere with

INSTALLATION CONSIDERATIONS (CONTINUED)
the WS110R. If you must locate the WS110R near electrical devices, install it in a separate metal
electrical box, ground the box to the electrical system ground, and route the WS110R cable several
feet away from all electrical wiring.
AVOIDING INTERFERENCE
The WS110R is designed to work in most applications including plasma and LCD displays and in
areas where CFL lighting and indirect sunlight are present. You should avoid locating the WS110R
near potential sources of electrical or optical noise, such as light dimmers or low-voltage lights.
Avoid locating the WS110R near any potential sources of electrical or optical noise, such as light
dimmers, low-voltage lights, and neon lights.
AVOIDING OPTICAL FEEDBACK
If installing the WS110R in the same room as an IR flasher, it is possible for the flasher’s IR output
to be picked-up by the WS110R. 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.

CHANGING THE COLOR OF THE WS110R
The Decora-style insert on the WS110R is removable, allowing fast and easy color
changes as needed. Inserts are available in a variety of colors.
If you need to change the color of the WS110R:
1. Obtain the WS110R Decora-style insert in the desired color from
your Niles dealer.
2. Hold the WS110R as shown in Figure 3. Locate the two plastic
mounting tabs at the top rear of the Decora-style insert. Using two
fingers, simultaneously press both tabs down (towards the center
of the insert) and forward (away from you) until the insert pops free
from its mounting slots.
3. Locate the new Decora-style insert. Hold the WS110R so that it is
facing you. Insert the two bottom tabs into the bottom slots first,
followed by the two tabs on the top. Snap the insert into place by
carefully pressing on the front of the insert.
