INSTALLATION STEP 6

Install the Door Control

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.

1. Strip 1/4" 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 trave to the full
open position, but will not return to the close position
until the sensor beam is connected and properly
aligned. See Safety Reversing Sensor instructions
beginning on page 21.
