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 moving parts
of door and door hardware. 

1. Strip 7/16" of insulation from one end of bell wire

and connect to the two screw terminals on back of
door control by color: white wire to 2 and white/red
wire to the 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 bell wire up wall and across ceiling to motor

unit. Use insulated staples to secure wire in
several places. Do not pierce wire with a staple,
creating a short or open circuit. 

4. Strip 7/16" of insulation from end of bell wire.

Connect bell wire to the quick-connect terminals
as follows: white to white and white/red to red.

NOTE:

When connecting multiple door controls to

the opener, twist same color wires together. Insert
wires into quick-connect holes: white to white and
red/white to red.

5. Use tacks or staples to permanently attach

entrapment warning label to wall near door control,
and manual release/safety reverse test label in a
prominent location on inside of 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.
