Installation Step 6
Install the Door Control
16
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death.
Install the Door Control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware,
but where the garage door is visible.
Do not allow children to operate the push
buttons or the remote control transmitters.
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it
clearly, and there are no obstructions to door
travel.
• Strip 1/4" of insulation from one end of the bell
wire; connect the wire to the two screw terminals
on the back of the Door Control: white to 2, and
white/red to 1.
• Locate the Door Control within sight of the
door at a minimum height of 5 feet where small
children cannot reach, and away from all
moving parts of the door and door hardware.
Fasten the Door Control securely with 6ABx1-1/2"
screws. If installing into drywall, drill 5/32" holes
and use the anchors provided.
• Run the bell wire up the wall and across the ceiling
to the opener. Use insulated staples to secure the
wire in several places. Be careful not to pierce the
wire with a staple, thereby resulting in a short.
• Receiver terminal screws and the antenna are
located on the back panel of the opener. Position
the antenna wire as shown.
• Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
• Remember to affix the User Safety Instruction
label to the wall near the Door Control, and the
Maintenance Instruction Label in a prominent
location on the inside of the garage door.
If the label adhesive will not adhere to your garage
wall surface (or becomes loose with time), use tacks
to secure the label alongside the Door Control.
Page 29 explains how to operate the opener using
the door control.
Do NOT connect the power and operate the
opener at this time. The trolley will travel to the
full
open position but will not return to the
close position until the sensor beam is
connected and properly aligned.
