To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door
control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a closing
garage door:
• Install door control within sight of garage door, out of reach
of children at a minimum height of 5 feet (1.5 m) and away
from ALL moving parts of door.
• NEVER permit children to operate or play with door control
push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is properly
adjusted and there are no obstructions to door travel.
• ALWAYS keep garage door in sight until completely closed.
NEVER permit anyone to cross path of closing garage door.
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,
away from moving parts of door and door hardware.
If installing into drywall, drill 5/32" holes and use the
anchors provided. For pre-wired installations (as in new
home construction), it may be mounted to a single gang
box (Figure 2).
1. Strip 7/16" (11 mm) 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. Remove cover by gently prying at slot in top of the
cover with a small flat head screwdriver. Fasten with
6ABx1-1/4" self-tapping screws (drywall installation) or
6-32x1" machine screws (into gang box) as follows:
• Install bottom screw, allowing 1/8" (3 mm) to protrude
above wall surface.
• Position bottom of door control on screw head and
slide down to secure. Adjust screw for snug fit.
• Drill and install top screw with care to avoid cracking
plastic housing. Do not overtighten.
• Insert top tabs and snap on cover.
3. (For standard installation only) 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" (11 mm) 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 power
and operate 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.
