INTRODUCTION
The Niles TS120 is a tabletop infrared sensor designed for use with the Niles infrared extender
systems.
Installed in a remote room location, the TS120 receives the IR commands transmitted from your
hand-held remote(s). The IR commands are carried via a CAT-5 cable to your A/V equipment in
another room, and instantly “repeated”.
The TS120 represents one of the 3 building blocks necessary to complete a Niles IR repeating
system:

INSTALLATION CONSIDERATIONS
TYPE OF CABLE
The TS120 connects to the Niles infrared main system 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.
TS120 MOUNTING LOCATION
The TS120 is ideal for use in applications when ceiling or wall-mounting is undesirable. Its small size
and unobtrusive appearance makes it ideal for installation in existing homes or cabinets with great
ease and minimal custom work. Installing the TS120 close to the primary location of the user will
ensure best performance.
The TS120 is designed to mount over or under almost any flat horizontal surface. Convenient
mounting locations for the TS120 are:

t0OBTIFMGJOBOFOUFSUBJONFOUDFOUFS
t6OEFSBTIFMGJOBOFOUFSUBJONFOUDFOUFS
TECH TIP: Wire size is expressed by it’s AWG (American Wire Gauge) number. The lower
the AWG number, the larger the wire, i.e., 20 AWG wire is physically larger than 22 AWG.

INSTALLATION CONSIDERATIONS (CONTINUED)
RECEIVING RANGE AND PICKUP ANGLE
The receiving range of the TS120 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 TS120. The IR pickup angle
of the TS120 is 30° off-axis (horizontal and vertical) at 25’.
AVOIDING ELECTRICAL INTERFERENCE
Avoid locating the TS120 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 TS120 in the same room as an IR flasher, it is possible for the flasher’s IR output
to be picked-up by the TS120. 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:

AVOIDING INTERFERENCE
TS120 is designed to work in most applications including with plasma and LCD TV’s and in areas
where CFL lighting and indirect sunlight are present. You should avoid locating the TS120 near
potential sources of electrical or optical noise, such as light dimmers or low-voltage lights.
USING THE POWER STATUS DISPLAY
The Green power status LED can only be activated by a “power status” broadcast from a Niles IR
main system unit (MSU140, MSU250, MSU480, MSU440Z). The IR main system unit will broadcast
the power status signal if the preamp/ receiver is on and a 12V DC adapter is plugged into the
preamp/receiver’s switched AC outlet and the 3.5mm plug is connected to the IR main system unit’s
Status input jack (Figure 2).
NOTE: THE 12V DC ADAPTER PLUGGED INTO THE SWITCHED OUTLET OF THE STEREO RECEIVER IS NOT
INCLUDED WITH THE IR MAIN SYSTEM UNIT. IT SHOULD BE 12V DC WITH A MINIMUM OF 100MA OF
OUTPUT. IT CAN BE ORDERED FROM YOUR NILES DEALER (FG01035 POWER ADAPTER).
USING THE TS120 WITH NILES MULTIZONE KEYPADS WITH AN IR CONNECTION
The TS120 is fully compatible with any Niles MultiZone Keypad with an IR connection, follow the
wiring instructions in Figure 4. For specific information see your Niles MultiZone Keypad manual.
