INSTALLATION CONSIDERATIONS
Type
of
Cable
The
MS120
connects
to
the
Niles
infrared
main
systems
unit
or
IRH61
0
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.
MS120
Mounting
Location
The
MS120
is
ideal
for
use
in
applications
when
tabletop,
ceiling,
or
wall-mounting
is
undesirable.
Its
small
size
and
unobtrusive
appearance
makes
it
ideal
for
installation
in
obscJ,Jre,
hidden
locations,
in
cabinet
facings,
or
in
the
sensor
knockout
built
into
Niles
in-wall
loudspeakers.
Installing
the
MS120
close
to
the
primary
location
of
the
user
will
ensure
best
performance.
The
MS120
is
designed
to
flush-mount
almost
anywhere.
Convenient
mounting
locations
for
the
MS120
are:
•
In
a
cabinet
door
•
In
a
wall,
or
wall-plate
•
Behind
a
speaker
grille.*
NOTE:
Some
types
of
speaker
grilles
will
reduce
the
IR
pickup
range
of
the
MS120.
If
unsu:e,
tes.t
the
pickup
range
before
permanently
mstallmg
the
MS120
behind
the
speaker
grille.
3
Receiving
Range
and
Pickup
Angle
The
receiving
range
of
the
MS120
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
AM
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
MS120.
The
IR
pickup
angle
of
the
MS120
is
30°
off-axis
(horizontal
and
vertical)
at
25'.
Avoiding
Electrical
Interference
Avoid
locating
the
MS120
near
any
potential
sources
of
electrical
or
optical
noise,
such
as
light
dimmers,
low-voltage
lights,
and
neon
lights.
Do
not
install
the
MS120
into
electrical
boxes
with
110
volt
devices
Some
states
or
municipalities
allow
devices
such
as
the
MS120
to
be
installed
into
the
same
electrical
box
as
110
volt
devices,
provided
a
"Iow-
voltage
partition"
is
used
between
the
devices.
