IMPORTANTINFORMATIONABOUTTHESAFETYREVERSINGSENSOR
Whenproperly connected andaligned, thesensor will detectan
obstacle in the path of its electronic beam.Thesending eye(with
an amber indicator light) transmits an invisible light beamto
the receiving eye(with a green indicator light). If an obstruction
breaksthe light beamwhile the door is closing, the door will stop
and reverseto full open position, and the openerlights will flash
10 times.
Theunits must be installedinsidethe garageso that the sending
and receivingeyesface eachother acrossthe door, no more than
6"(15 cm) abovethe floor. Eithercan be installedon the left or
right of the door as long as the sun never shines directly into the
receiving eyelens.
Themounting brackets aredesignedto clip ontothe track of
sectionalgarage doors without additional hardware.
Besure power is NOTconnectedto the garagedoor opener
BEFOREinstalling the safety reversingsensor.
To preventSERIOUSINJURYor DEATHfrom a closing garage
door:
• Correctly connect andalign the safety reversing sensor.This
required safety device MUSTNOTbedisabled.
• Install the safety reversingsensor so beam is NOHIGHER
than 6" (15 cm) abovegaragefloor.
If it is necessaryto mount the units on the wall, the brackets must
be securelyfastened to a solid surfacesuch asthe wall framing.
Extensionbrackets (seeAccessories) are availableif needed.If
installing in masonry construction, add a pieceof wood ateach
location to avoiddrilling extraholes in masonry if repositioning is
necessary.
Theinvisible light beam pathmust be unobstructed. No part of
the garagedoor (or door tracks, springs, hinges, rollersor other
hardware) may interrupt the beamwhile the door is closing.

INSTALLINGTHEBRACKETS
Besurepower tothe opener isdisconnected.Install and align
the brackets sothe sensors will face each other acrossthe garage
door, with the beamno higher than 6" (15 cm) abovethe floor.
They may be installed in one of three ways, asfollows.
Garagedoortrack installation (preferred):
1. Slip the curved arms overthe rounded edgeof eachdoor track,
with the curved arms facing the door. Snap into placeagainst
the side of the track. It should lie flush, with the lip hugging the
back edgeof the track, as shown in Figure1.
If your door track will not support the bracketsecurely, wall
installation is recommended.
Wall installation (Figures2 & 3):
1. Placethe bracketagainstthe wall with curved arms facingthe
door. Besurethere is enough clearancefor the sensor beamto
be unobstructed.
2. If additional depth is needed,anextension bracket
(seeAccessories)or wood blocks can be used.
3. Usebracketmounting holes asa template to locate and drill (2)
3/16" diameter pilot holes on the wall at eachside of the door,
no higher than 6" (15 cm) above the floor.
4. Attach bracketsto wall with lag screws (not provided).
5. If using extension bracketsor wood blocks, adjust right and
left assembliesto the same distance out from the mounting
surface. Makesure all door hardwareobstructions are cleared.
Floor installation (Figure 4):
1. Usewood blocks or extension brackets (seeAccessories) to
elevatesensorbrackets sothe lenses will be no higher than
6"(15 cm) abovethe floor.
2. Carefully measureand placeright and left assembliesat the

MOUNTINGANDWIRINGTHESAFETYREVERSINGSENSORS
1. Slide a 1/4"-20xl/2" carriage bolt headinto the slot on each
sensor. Usewing nuts to fastensensors to brackets, with
lenses pointing toward eachother across the door. Besure the
lens is not obstructed by a bracket extension (Figure5).
2. Finger tighten the wing nuts.
3. Runthe wires from both sensors to the opener. Use insulated
staplesto secure wire to wall and ceiling.
4. Strip 7/16" (11 mm) of insulation from each set of wires.
Separatewhite and white/black wires sufficiently to connect to
the opener quick-connect terminals. Twist like colored wires
together. Insert wires into quick-connect holes:white to white
and white/black to grey (Figure 6).
ALIGNINGTHESAFETYREVERSINGSENSORS
1. Plug in the opener. The indicator lights in both the sending and
receiving eyeswill glow steadilyif wiring connections and
alignment are correct.
Thesending eyeamber indicator light will glow regardlessof
alignment or obstruction. If the green indicator light in the
receiving eyeis off, dim, or flickering (and the invisible light beam
path is not obstructed), alignment is required.
2. Loosenthe sending eyewing nut and readjust, aiming directly
at the receiving eye.Lock in place.
3. Loosenthe receiving eye wing nut and adjust sensor until it
receivesthe sender's beam. Whenthe green indicator light
glows steadily, tighten the wing nut.

TROUBLESHOOTINGTHESAFETYREVERSINGSENSORS
1. If the sending eyeindicator light does not glow steadily after
installation, checkfor:
• Electric powerto the opener.
• A short inthe white or white/black wires. Thesecanoccur at
staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
2. If the sending eye indicator light glows steadily but the
receiving eyeindicator light doesn't:
• Checkalignment.
• Checkfor an open wire to the receiving eye.
3. If the receiving eyeindicator light is dim, realigneither sensor.
NOTE:Whenthe invisible beam path is obstructed ormisaligned
while the door is closing, the door will reverse. If the door is
already open, it will not close. The openerlights will blink 10
times. Seepage 20.
