Step 12: Install Wireless Infrared Safety Sensors Wall Mounting Bracket
(If Included)
Select a mounting position 5 inches above the floor to center line of wall bracket.
The EMITTER and TRANSPONDER units must be mounted inside the door
opening to minimize any interference by the sun; however, the sensors must be
mounted against the door track. The brackets may be temporarily mounted to the
wall (or jamb) with a #8 X1/2” screw provided and should be in contact with the
door track. Leave this screw in place after installation is completed to prevent
accidental rotation of beam sensor. It is very important that both wall brackets
be mounted at the same height for proper alignment.
Using the 1/4” x 3/4” lag screw provided, attach the wall mounting bracket to the
wall. In some installations it may be necessary to attach wooden spacers to the
wall to achieve the required clearance. Expansion bolts (not supplied) may be
required to attach brackets to walls constructed of materials other than wood or
gypsum.
Step 13: Install Wireless Infrared Safety Sensor Bracket
Attach the sensor bracket to the wall bracket using the
two #8 x 1-1/2” screws supplied (make sure that the
curved hooks protruding from the bracket are positioned
over and in firm contact with the door track).
Note: This opener is equipped with state-of-the-art wire-
less infrared safety sensors which are activated by door
movement. It is extremely important to position and
mount the sensor brackets in firm contact with the door
track so that the sensors are immediately activated by
the door movement.
Step 14: Install Wireless Infrared Safety Sensor
Open hinged cover on infrared safety sensors and remove battery protective paper strip.
Observe proper battery polarity, as illustrated, in battery compartment.
Identify the TRANSPONDER (green LED) and
mount this unit on the right side (from inside the
garage looking to the outside) of the garage door
and the EMITTER (red LED) on the left side. This
same right/left mounting procedure must be fol-
lowed on two and three door installations.
Mount the infrared safety sensors to
the sensor bracket keeping the soft
washer between the sensor and sen-
sor bracket and then place the conical
washer, lock washer and hex nut on
the extender bolt, as illustrated.
Keeping the sensors pointing in towards door and aimed at each other,
tighten nut until there is enough friction to hold in place. Do not fully tighten
until the final alignment has been completed.
