OPERATION

Operation of the CS120 is straightforward. Simply aim your hand-held remote at the CS120. Your IR

command is instantly repeated to your A/V equipment.

TROUBLESHOOTING

This manual contains instructions for the CS120 only. For specific information on the adjustment and operation of your Niles infrared extender sys-

tem, please refer to the instruction manual included

with your Niles IR main system unit (MSU140, MSU250, MSU480, MSU440Z).

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 CS120 and on the main system unit. Look for open, shorted or reversed wires (Figure 2)

3. Test for interference from the following sources:

• Neon, Compact Florescent Lighting (CFL), or halogen lights in the room

• Light dimmers, beginning with those closest

to the CS120

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

11 1312

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 an MF1 or MF2 MicroFlasher

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. 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. If you require further assistance call Niles

Technical Support at 305-238-4373 or 1-800-289-4434 (M-F 8:00 AM - 7:00PM ET).

CS120

INSTALLATION & OPERATION GUIDE

CEILING-MOUNT IR MICROSENSOR

CS1 2 0

INTRODUCTION

The CS120 is a ceiling mounted IR sensor designed for use with the Niles infrared extender systems. Installed in a remote room location, the CS120 receives the IR commands transmitted from your existing hand-held 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 CS120 is compatible with all current Niles infrared systems. It may be used along with, or as an alternative to, the Niles TS120, MS120, MS220, WS120R and MVC100IR sensors or the IntelliPad

The CS120 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 WS120R, 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 & BENEFITS

The CS120 offers a number of improvements over other miniature IR sensors.

• Wideband High-Fidelity Design enables operation with virtually any brand of equipment

• Patent Pending Universal Noise Suppression enables operation in virtually any environment: near plasma and LCD displays, compact fluorescent lights, and indirect sunlight

• Excellent IR receiving range — 20’ to 35’ of remote control range (depending upon the strength of your handheld remote)

• Factory tested for pickup range and angle

• Small size of only 1/2” diameter by 2-7/8” long—fits almost anywhere

• 10’ of connecting wire included

• Printed circuit board design uses surface mount technology, assuring high reliability

• Ideal for both home and commercial installations

• Each CS120 includes a transparent cover

• Two year parts and labor limited warranty

INSTALLATION CONSIDERATIONS

IMPORTANT: REFER INSTALLATION TO A PROFESSIONAL CUSTOM INSTALLER IF YOU ARE UNFAMILIAR WITH ANY OF THE FOLLOWING PROCEDURES.

TOOLS REQUIRED

• 1/8” Standard Slotted Screwdriver

• 1/4” Standard Slotted Screwdriver

• Wire Stripper

Type of Cable

The CS120 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.

CS120 Mounting Location

The CS120 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 CS120 will vary according to the IR output strength of the remote control being used. Remote strength varies among brands

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 CS120. The IR pickup angle of the CS120 is 30° off-axis (horizontal and vertical) at 25’.

Avoiding Interference

CS120 is designed to work in most applications including with LCD and plasma displays and in areas where CFL lighting and indirect sunlight are present. You should avoid locating the CS120 near potential sources of electrical or optical noise, such as light dimmers or low-voltage lights.

Avoiding Optical Feedback

If installing the CS120 in the same room as an IR

flasher, it is possible for the flasher’s IR output to be picked-up by the CS120. 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 an MF1 or MF2 Microflasher and cover them with the supplied IR blockers

Using the CS120 with the Niles MultiZone keypads with an IR connection

The CS120 is fully compatible with Niles MultiZone

keypads with an IR connection, follow the wiring instructions in

Figure 5. For specific information

see your Niles MultiZone keypad manual.

INSTALLATION

If you are installing the CS120 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 CS120

2. Drill a 11/16" hole where the CS120 will be

mounted

3. Run the CS120’s IR cable. Label the cable for future reference (

Figure 2). The CS120 is sup-

plied with 10’ of pre-stripped IR cable. The IR cable may be shortened or lengthened as needed. If you want to make the CS120’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 CS120 cable to another cable by soldering or crimping the connections.

4. Fasten sensor to ceiling with supplied screws (

Figure 3)

5. Connect the CS120 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 system unit manual for specific installation instrutions.
