The
sending
eye
transmits
an
invisible
light beam
to
the
receiving
eye.
The
units
can be
installed
on
either
side
of the
garage
door
as long
as
the sun
never shines
directly
into the
receiving
eye
lens.
Look
at the
label
on
the connector
end
of
each
case
to identify
the sensors.
The brackets
must
be
connected
and
fastened
so
that the
sending
and
receiving
eyes
face
each
other
as shown
in Figure
1.
lf an
obstruction
breaks
the
light
beam
while
the
garage
door
is
closing,
the
door
will
stop
and
reverse
to
full open
position,
and
the opener
lights
will
flash
for 5
seconds.

The brackets
musf
be
securely
fastened
to a
solid
surface
such
as the
studs
on
either
side
of the
door,
or add
a
piece
of
wood
at
each location
if installing

masonry
construction.
The

must
be
unobstructed'
No
part
of
the
garage

(or
door
tracks,
springs,
hinges,
rollers
or
other
hardware)
can
interrupt
the

while the

is
closing.
lf
it does,
use
a
piece
of
wood
to build
out
each
sensor
mounting
location
to
the
minimum
depth
required
for
light beam
clearance.
