INTRODUCTION

The IRB1 is a small, cabinet-mount high output

infrared flasher. The IRB1 is just one part of the
three building blocks necessary to complete a
Niles IR extender system:

• IR Main System Unit—Models MSU140,
MSU250, MSU480 and MSU440Z.

• IR Sensors/Keypads—Models WS100, TS100,
MS100, MS200, CS100, MVC100IR and the

®

IntelliPad

• IR Flashers—Models MF1, MF1VF, MF2,
MF2VF and the IRB1.

An IR sensor expansion hub, Model IRH610,
is available to provide additional sensor inputs
to your system.

When an IR remote sensor receives a command
from a hand-held remote control, it sends a cor­responding electronic signal through a wire to
the main system unit. Here, the main system
unit cleans and amplifies the electronic signal.
Finally, the main system unit outputs the signal
to the IR flasher which relays the infrared com­mand to the audio/video component you wish
to control.

The IRB1 relays the infrared command using
“flashes” of infrared light in a powerful flood­ing pattern from its two infrared LEDs. The out­put is extraordinarily accurate over a wide
bandwidth. This allows the IRB1 to control
most makes and models of IR controlled
audio/video components.

FEATURES & BENEFITS

• Two infrared LEDs give the IRB1 exceptional

range and power. With proper placement, a
single IRB1 flasher can control an entire stack
of audio/video components.

• The IRB1 is equipped with a 3.5mm plug.
This provides you with easy hookup.

• An adhesive-backed strip is included with the
IRB1, providing quick, secure, mounting.

• The IRB1 is supplied with an ample 10' of
connecting wire.

INSTALLATION CONSIDERATIONS

The IRB1 is typically used as a “flooding” flasher

to control a stack of audio/video components.
For this type of application, place the IRB1 with
its LEDs pointed straight up and at least an inch
in front of the equipment you wish to control
(See Figure 2). The effective range varies
between 8' to 30' depending on the brand
and/or the model of the audio/video compo­nent. Note: If cabinet dimensions permit, experi­menting with the placement of the IRB1 may
yield better operating results.

For tall stacks of components use multiple IRB1
flashers. For example, place one IRB1 at the top
of a stack with the LEDs pointing down and one
IRB1 at the base of the stack with the LEDs
pointing up (See Figure 3).

In some installations there are shelves blocking
a direct path between the IRB1 and the compo­nents’ IR sensor window. It is possible to
bounce infrared light off of smooth reflective
surfaces (particularly white surfaces). If a suit­able surface exists (like the back of a cabinet
door, or a white wall within a few feet) try to
place the IRB1 so that its reflected output reach­es the sensor windows of the components (See
Figure 4). If some of the components are still not
getting adequate signal, mount a Niles MF series
MicroFlasher
the problematic components.

Sometimes, it is desirable to mount the IRB1 so
that it directly faces the equipment from across

®

on the sensor window of each of

a room. In this type of situation the IRB1 has an
effective operational range of 18' to 30'
(depending on brand and model of audio/video
equipment).

INSTALLATION & OPERATION

Route the connecting wire to the main system

unit. Most Niles IR main system units feature
specific flasher outputs that are selectable
between low and high output. Insert the 3.5mm
plug of the IRB1into one of these selectable
“FLASHER OUTPUTS” jacks on the MSU. Slide
the corresponding switch on the MSU to the
”high” position (See Figure 1).

unit’s flasher outputs.

Increasing the Wire Length

If the connecting wire is too short to reach the

main system unit, a new length of heavier gauge
wire should be spliced onto a six inch length of
the original wire. For distances between ten and
twenty feet upgrade the original wire to an
