Introduction

The CS100 is a ceiling mounted IR sensor designed for use
with the Niles infrared extender systems.

Installed in a remote room location, the CS100 receives the
IR commands transmitted from your existing hand­held remotes in that room. The commands are carried via a
category 5 cable to your A/V equipment in another room, and
instantly “repeated”.

The CS100 is compatible with all current Niles infrared
systems. It may be used along with, or as an alternative
to, the Niles TS100, MS100, MS200, WS100 and MVC100IR
sensors or the IntelliPad

The CS100 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, MVC100R 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 CS100 offers a number of improvements over other
miniature IR sensors.

• Plasma-proof performance—allows placement of the CS100
near plasma 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 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 1-5/8" diameter by 3" long—fits almost
anywhere.

• 10' of connecting wire included.

• Printed circuit board design uses surface mount technology
(SMT), assuring high reliability.

• Ideal for both home and commercial installations.

• Each CS100 includes a transparent cover.

• Two year parts and labor warranty.

Installation Considerations

Type of Cable

The CS100 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.

CS100 Mounting Location

The CS100 is designed to be ceiling mounted in a direct line of
sight location within the operating range of the remote control.

Receiving Range and Pickup Angle

The receiving range of the CS100 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 18' to a maximum of about 30'.

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 CS100.

The IR pickup angle of the CS100 is 30° off-axis (horizontal
and vertical) at 20'.

Avoiding Interference

CS100 is designed to work in most applications including
plasma displays and in areas where CFL lighting and indirect
sunlight are present. You should avoid locating the CS100
near potential sources of electrical or optical noise, such as
light dimmers or low-voltage lights.

Avoiding Optical Feedback

If installing the CS100 in the same room as an IR flasher, it is
possible for the flasher’s IR output to be picked-up by the
CS100. 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 Microflashers and cover them with
the supplied IR blockers.

Using the CS100 with the Intellipad Ci system.

The CS100 is fully compatible with the Niles Intellipad Ci line,
follow the wiring instructions in Figure 5. For specific information
see your Intellipad Ci manual.

Installation

If you are installing the CS100 into an existing ceiling, take
time to consider any possible obstructions which may be
hidden, such as wood or metal studs, electrical, telephone or
other types of wiring, plumbing, AC or heating conduits, etc.

1. Determine a mounting location for the CS100.

2. Drill a 7/8" hole where the CS100 will be mounted.

3. Run the CS100’s IR cable. Label the cable for future reference
(Figure 2). The CS100 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 CS100’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 CS100 cable to another cable by soldering or
crimping the connections.

4. Fasten sensor to ceiling with supplied screws (Figure 3).

5. Connect the CS100 cable to the main system unit (Figure 1).
Strip 1/4" of insulation from the end of each wire. Tightly
twist the end of each wire until there are no frayed ends.
Insert each wire into the appropriate hole on the removable
connector plug, and snap the locking tab down.

To help you, the connector plug is keyed. Insert the smooth
side of the connector plug into the smooth side of the socket.
Don’t force the scalloped side of the connector plug into the
smooth side of the socket. Refer to the main system main sys-

tem unit manual for specific installation instructions

Operation

Operation of the CS100 is straightforward. Simply aim your
hand-held remote at the CS100. Your IR command is instantly
repeated to your A/V equipment.

Troubleshooting

This manual contains instructions for the CS100 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 CS100 and on
the main system unit. Look for open, shorted or reversed
wires (Figure 2).

3. Test for interference from the following sources:

• Neon or halogen lights in the room

• Light dimmers, beginning with those closest to the CS100

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.

The conditions which sometimes combine to create a
feedback loop are:

1. Both a sensor and a flasher are located within the same room.

2. There is some low-level noise or interference on your system.

You can eliminate optical feedback by replacing any
IRB1 “flooding flasher” with MF1 or MF2 MicroFlashers and
covering all flashers with the supplied IR blocking covers.

EMI (Electromagnetic Interference)

Identify the source of the interference. The most common
sources of electromagnetic interference are listed in the
Installation Considerations section on pages 3 and 4. To elimi­nate EMI try the following methods:

1. Move the sensor or the sensor cable away from the EMI
source

or move the source of the EMI away from the sensor

or the cable.

2. Connect the Sensor’s GND terminal to true earth ground
(if this isn’t feasible use the main system unit’s GND terminal).

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.
