OWNERS INSTRUCTIONS

The two and three garage door multi-function control panel is designed to replace multiple door control buttons on LiftMaster Security garage door openers. It can be used as a replacement stand alone unit or in conjunction with the original factory door control buttons. Never connect more than two control panels or door control buttons to any one garage door opener.

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
  Wire white wire to White-1 and red/white wire to Red-1

• Middle Door Door B
  Wire white wire to White-2 and red/white wire to Red-2 Note: Model 902 LM will only have A and C terminals.

• Right Door – Door C
  Wire white wire to White-3 and red/white wire to Red-3

NOTE: If replacing existing wall controls, labeling the existing wires with masking tape might be 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. White to WHITE 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 button may stick if the door control is not mounted on a smooth surface. If a click is not heard when pressing the door control button, loosen the two mounting screws or relocate the door control to a smoother surface. After installation, an orange indicator light behind the door control buttons will indicate proper connection. If not lit, the Lock and Light features will not function (reverse wires to correct).

FOR WALL BOARD (DRYWALL) MOUNT

Remove the left and right door control buttons by gently twisting at the top with a small flat blade screwdriver exposing the horizontal installation holes. Figure 2. Mark and drill wall board. Drill 7/32″ holes and use anchors provided. Fasten with 1-1/4″ self-tapping screws. Do not overtighten. Insert bottom tabs and snap on door control buttons. Figure 3

FOR MOUNTING ONTO A SINGLE ELECTRICAL GANG BOX

Remove the center cover or door control button by gently prying at slot in top of the door control button with a small flat blade screwdriver exposing two installation holes. Figure 2. For flexibility, this wall control can be mounted either left or right of center directly over gang box. Use 6-32X1″ machine screws. Install bottom screw, allowing 1/8″ to protrude above wall surface. Position bottom of door control on screw head and slide down to secure. Adjust screw for snug fit. Install matching top machine screw. Do not overtighten. Insert bottom tab and snap center cover or door control button. Figure 4.

NOTE: Mounting hardware is included for each type of installation (use all four screws if desired).

A single blink indicates that the timer is reset to 1-1/2 minutes. Repeat the procedure and the light will blink twice, resetting the timer to 2-1/2 minutes. Repeat again for a 3-1/2 minute interval, etc., up to a maximum of four blinks and 4-1/2 minutes.
