Lift-master 78LM Manual

FOR USE WITH GARAGE DOOR OPENERS MANUFACTURED AFTER JANUARY 1, 1995. To ensure proper functioning of your opener, remove all old or previous push buttons/wall control panels. Use only the enclosed door control for proper operation.

Locate the door control within sight of the door at a minimum height of 5 feet (1.5 m) where small children cannot reach, and away from all moving parts of the door and door hardware.

INSTALLATION

The door control is typically attached directly to the wall. For pre-wired installations (as in new home construction) it can be mounted to a standard single gang box.

1.Disconnect power to the garage door opener.

2.Strip 1/4" (6 mm) of insulation from one end of the bell wire and connect to the two screw terminals on the back of the door control as follows: red/white wire to 1 and white wire to 2.

NOTE: After installation, the indicator light behind the push button cover will indicate proper connection.

3.Remove the push button cover by gently prying off the top edge with a screwdriver. Fasten with 6ABx1-1/4" self-tapping screws (standard installation) or 6-32x1" machine screws (pre-wired installation) as follows:

ï(Standard Installation ONLY) Drill pilot holes and install bottom screw, allowing 1/8" (3 mm) to protrude above the wall surface.

ïPosition bottom of door control on screw head and slide down to secure. Adjust screw for snug fit.

ïInstall top screw. Do NOT overtighten, you may damage the plastic housing.

4.(Standard Installations ONLY) Run bell wire up wall and across ceiling to motor unit. Use insulated staples to secure wire to wall and ceiling in several places. Do NOT pierce wire with a staple, this will create a short or open circuit.

5.Strip 7/16" (11 mm) of insulation from the end of the bell wire.

6.Connect bell wire to terminals as follows:

ïQuick Connect Terminals: Red/white wire to red terminal and white wire to white (Figure 1).

ïScrew Terminals: Red/white to 1 and white to 2 (Figure 2).

7.Reconnect power to the garage door opener.

8.Replace the cover by inserting the bottom tabs and snapping it into place. Test the wall control to ensure proper operation.

OPERATION

To activate: Press and hold the Lock button for 2 seconds. The push button indicator light will flash as long as the lock is on. To turn off: Press and hold the Lock button again for 2 seconds.
