IR Blocking
All MicroFlashers come equipped with
a 3.5mm mono mini-plug. This provides
you with easy hookup for fast, trouble-free
• All MicroFlashers have a strip of self-adhesive
tape for quick and secure mounting to any
hard, clean, dry surface.
• All MicroFlashers are supplied with an ample
10 feet of connecting wire.
The MF1 and MF2 are supplied with an
infrared blocking cover. This is useful if you
have several identical
TV’s (or audio/video
components), all using the same remote
control and the same IR commands.
Locate the IR remote sensor window of each
component you want to control. The sensor is
usually located behind its own plastic window
on the front of the component. On some equip-
ment, the sensor may be hidden behind the
plastic bezel covering the front panel displays.
A bright flashlight is helpful for locating sensors
on equipment with very dark plastic bezels.
Make sure the mounting surface is cleaned and
degreased before installation. Attach the
MicroFlasher directly over the IR remote sensor
window of the component using its self-adhe-
sive tape. The adhesive is strong enough to hold
the flasher firmly in place yet it removes easily
and without residue if needed. Route the
connecting two-conductor wire to the Main
System Unit and plug it into one of the flasher
outputs (Figure 3). Coil any excess wire and tie it
in place.
The MF Series of MicroFlashers are miniature
panel-mount IR flashers. They are one of three
elements needed to complete a remote control
extender system:
IR Main System Unit—Models MSU140,
MSU250, MSU480 and MSU440Z.
• IR Sensors/Keypads—Models WS100, TS100,
MS100, MS200, CS100, MVC100IR and the
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 transmits the infrared
command to the audio/video component you
wish to control.
The MF MicroFlasher
sends the IR commands
via flashes of infrared light in a precise pinpoint
pattern from its single infrared LED. The output
is extraordinarily accurate throughout a wide
bandwidth. This allows the MF MicroFlashers to
control most makes and models of IR controlled
audio/video components.
The MF2 and MF2VF provide dual flashers on a
single cable for simplified wiring or easy expan-
sion of a main system units flasher outputs.
• The MF1VF and MF2VF provide visible feed-
back of flasher operation via a red LED in the
flasher housing.
The MF Series MicroFlashers are typically
mounted to the infrared remote sensor window
of an audio/video component using the attached
self-adhesive tape (Figure 2). The flasher directs
its infrared output towards the sensor, not out
into the room. Route the connecting wires close
to the IR remote sensor window. That way, the
minimum amount of wire will show. If the com-
ponent has a tray or door that opens, you may
have to route the wire from the top or bottom of
the component. Make sure any loose connect-
ing wire is taped securely in place and out of
the way.

Wire size is expressed by its
AWG (American Wire Gauge)
number. The lower the
number, the larger the
wire, i.e. twelve AWG
is physically larger
than fourteen AWG.
The MF MicroFlashers are compatible with all
Niles infrared extenders systems, IntelliControl
and MultiZone receivers and preamplifiers.
Miniature and discrete, the MF MicroFlashers
mount directly to the IR remote sensor win-
dow of your audio/video component without
disfiguring the appearance of your equipment.
The MF Series is completely transparent
to IR commands. Although the flashers appear
to block the IR remote sensor window of your
audio/video component, you can still directly
operate your equipment using a remote
WARNING! MF Series MicroFlashers may be
damaged by excessive flasher level output from
the Main System Unit!
On main system units with selectable flasher
outputs (MSU250, MSU480 and MSU440Z)
make certain the Hi-Low switch is placed in the
“Low” position (See Figure 3).
Increasing the Wire Length
If the connecting wire is too short to reach the
Main System Unit, an additional length of wire
may be spliced in to extend it. Cut the flasher
wire approximately six inches from the plug
end, strip off 1/4”, and connect your additional
wiring between the ends of the original flasher
wire. For distances between 10 and 20 feet
upgrade the original wire to an 18 gauge 2-con-
ductor wire. For distances of up to 200 feet a
16 gauge two-conductor wire should be used.
Over Please
The wire lead marked with a gray stripe
is positive (+); the unmarked lead is negative (-).
