Installation 5 Install the Door Control (Smart Control Panel®) Install door control within sight of garage door, out of reach of small children at a minimum height of 5 feet (1.5 m) above floors, landings, steps or any other adjacent walking surface, and away from ALL moving parts of door. Your garage door opener is compatible with up to 2 Smart Control Panels or 4 of any other Security+ 2.0 door controls. NOTE: Older LiftMaster door controls and third party products are not compatible. For gang box installations it is not necessary to drill holes or install the drywall anchors. Use the existing holes in the gang box. 1. Strip 7/16" (11 mm) of insulation from one end of the wire and separate the wires. 2. Connect one wire to each of the two screws on the back of the door control. The wires can be connected to either screw. PRE-WIRED INSTALLATIONS: Choose any two wires to connect, but make note of which wires are used. 3. Mark the location of the bottom mounting hole and drill a 5/32" (4 mm) hole. 4. Install the bottom screw, allowing 1/8" (3 mm) to protrude from the wall. 5. Position the bottom hole of the door control over the screw and slide down into place. 6. Lift the push bar up and mark the top hole. 7. Remove the door control from the wall and drill a 5/32" (4 mm) hole for the top screw. 8. Position the bottom hole of the door control over the screw and slide down into place. Attach the top screw. 9. Run the white and red/white wire from the door control to the garage door opener. Attach the wire to the wall and ceiling with the staples (not applicable for gang box or pre-wired installations). Do not pierce the wire with the staple as this may cause a short or an open circuit. 10. Connect the wire to the red and white terminals on the garage door opener. The wires can be connected to either terminal. 11. Fasten the warning placard to the wall next to the door control. NOTE: DO NOT connect the power and operate the garage door opener at this time. The door will travel to the full open position but will not return to the close position until the safety reversing sensors are connected and properly aligned. See page 14. To prevent possible SERIOUS INJURY or DEATH from electrocution: • Be sure power is NOT connected BEFORE installing door control. • Connect ONLY to 7-28 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 small children at a minimum height of 5 feet (1.5 m) above floors, landings, steps or any other adjacent walking surface, 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.
