Chamberlain LiftMaster 98LM Owner's Instructions

WARNING
CAUTION
FOR USE WITH GARAGE DOOR OPENERS
MANUFACTURED AFTER JANUARY 1, 1995.
This door control contains a motion detector
that will automatically turn on the light when
it detects a person entering the garage. This
feature can be easily turned off for extended
work light use.
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. If installing the
door control adjacent to existing door controls, be sure the
detector switch is accessible.
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 green indicator light behind
the push bar cover will indicate proper connection.
3. Remove the push bar 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:
• (Standard Installation ONLY) Drill pilot holes and install
bottom screw, allowing 1/8" (3 mm) to protrude above
the wall surface.
• Position bottom of door control on screw head and slide
down to secure. Adjust screw for snug fit.
• Install 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:
• Quick Connect Terminals: Red/white wire to red
terminal and white wire to white (Figure 1).
• Screw 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 top tabs and snapping
it into place. Test the wall control to ensure proper
operation.
NOTE: The automatic light feature will become functional
6-1/2 minutes after power is restored.
