Model 98LM
Motion Detecting Door Control Panel
OWNERS INSTRUCTIONS
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.

OPERATION
Door Control Push Bar: Press to open or close the door.
Press again to reverse the door during the closing cycle, or
to stop the door while it is opening.
Light Feature: Press the Light button to switch the opener
light on or off. When the door is opened or closed, the light
will remain on for 4-1/2 minutes. Press the Light button to
turn it off sooner. The Light button will not control the
opener light when the door is in motion. When using the
opener lights as working lights, we recommend that you
first disable the motion sensor. See Automatic Light
Override Feature, below.
When used with openers manufactured after
December 1, 1999, (check the date on the opener panel)
the 4-1/2 minute interval can be changed to 1-1/2, 2-1/2, or
3-1/2 minutes as follows: Press and hold the Lock button
until the light blinks (about 10 seconds). 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.
Automatic Light Feature: The opener light will turn on
automatically when a person enters the garage. When a
person walks in front of the door control, the opener light
will come on for five minutes, then shut off. This feature
works by detecting body heat. It is more sensitive in front
of the door control than at its sides, and works better as a
person moves closer. It may not work in temperatures
around 100˚F (38˚C).
To disable this feature, slide the Detector Switch on the
right side of the door control down (off).
Special note for older garage door openers: If this door
control is installed on an opener manufactured from
January 1, 1995 to December 1, 1999, the following
difference may apply: If the light is on when the opener is
actuated, the light may go off for a moment, then turn on
again as the detector senses you.
Automatic Light Override Feature: We recommend that
you disable the motion sensor when using the opener
lights as working lights. Otherwise, they will turn off
automatically if you are working beyond the sensor’s
range. Slide the Detector Switch on the right side of the
door control down (off), then press the light button to
control the lights.
