INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door at a minimum
height of 5 feet (1.5 m) where small children cannot reach,
and away from all moving parts of door and door
hardware.
1. Strip 1/4" (6 mm) of insulation from one end of the bell
wire. Connect it to the two screw terminals on the back
of the door control by color: white wire to 2 and
white/red wire to 1.
2. Fasten the Lighted Door Control Button securely with
6ABx1-1/2" screws. If installing into drywall, drill 5/32"
holes and use the anchors provided.
3. 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, creating a short or open circuit.
4. Receiver terminal screws and the antenna are located
on the back panel of the motor unit. Position the
antenna wire as shown.
5. Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
6. Use tacks or staples to permanently attach the
entrapment warning label to the wall near the door
control, and the manual release/safety reverse test in a
prominent location on the inside of the garage door.
NOTE: 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.
