INTROdUCTION
The Niles WS120 is a wall-mount, Decora® style IR sensor designed for use with the Niles infrared
extender systems.
Installed in a remote room location, the WS120 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 WS120 is compatible with all current Niles infrared systems. It may be used along with,
or as an alternative to, the Niles TS120, MS120, MS220, and CS120 sensors or the Niles
MultiZone Keypad.
The WS120 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 WS120, TS120, MS120, MS220, CS120, 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 WS120 offers a number of improvements over other wall-mount IR sensors.
• Wideband High-Fidelity Design enables operation with virtually any brand of equipment
• Patent Pending Universal Noise Suppression Design enables operation in virtually any environment: near plasma and LCD displays, compact uorescent lights, and indirect sunlight
• Excellent IR receiving range— you get 20’ to 35’ of remote control range (depending upon the
strength of your handheld remote)
• Small size of only 2-3/4” wide by 4-1/2” high by 1-1/4” deep — ts in a one-gang box
• Printed circuit board design uses surface mount technology (SMT), assuring high reliability
• Ideal for both home and commercial installations
• Two year parts and labor limited warranty

INSTALLATION CONSIdERATIONS
The WS120 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 WS120 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.
WS120 MOUNTING LOCATION
Locating the WS120 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 WS120 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 WS120 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 WS120. The IR pickup
angle of the WS120 is 30° off-axis (horizontal and vertical) at 25’.
JUNCTION BOxES
The mounting depth of the WS120 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 WS120 INTO ELECTRICAL BOxES WITh 110 vOLT dEvICES.
Some states or municipalities allow devices such as the WS120 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 WS120 can act as an “antenna” for
electrical noise. Locating the WS120 cable too close to a light dimmer or switch may interfere with
