INSTALLATION
Product may be mounted directly to wall board or, for pre-wired
installations (as in new home construction), it may be mounted to
a single gang box. In either case the installation surface must
be smooth and flat.
The door orientation goes from left to right, and wiring is as
follows:
• Left Door – Door A
ire white wire to hite-1 and red/white wire to Red-1
• Midd e Door – Door B
ire white wire to hite-2 and red/white wire to Red-2
Note: Model 902 LM will only have A and C terminals.
• Right Door – Door C
ire white wire to hite-3 and red/white wire to Red-3
NOTE: If replacing existing wall controls, la eling the existing
wires with masking tape might e helpful (i.e. Door A, Door B,
Door C).
1. Strip 7/16" of insulation from one end of bell wire and connect
to the corresponding two screw terminal on back of door
control by color. Figure 1. hite to HITE and red/white to
RED. Be careful to wrap the exposed wire tightly around the
screw and tighten. The exposed wire must not come into
contact with exposed solder points. The Mylar insulator is
there to prevent this from happening. Do not remove this
insulator.
2. 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.
3. Strip 7/16" of insulation from opposite end of bell wire.
Connect bell wire to the Quick-Connect™ terminals located on
garage door opener as follows: white to white and white/red to
red. Figure 5.
NOTE: The door control utton may stick if the door control is
not mounted on a smooth surface. If a click is not heard when
pressing the door control utton, loosen the two mounting
screws or relocate the door control to a smoother surface.
After installation, an orange indicator light ehind the door
control uttons will indicate proper connection. If not lit, the Lock
and Light features will not function (reverse wires to correct).
