Feature Overview
LIGHT BUTTON
Press the LIGHT button to turn the garage door opener lights on or off. When the lights are turned
on they will stay on until the LIGHT button is pressed again, or until the garage door opener is
activated. Once the garage door opener is activated the lights will turn off after the specified period
of time (the factory setting is 4-1/2 minutes). The LIGHT button will not control the lights when the
door is in motion.
MOTION SENSOR
The motion sensor will automatically turn on the garage door opener lights when motion is
detected. The lights will come on for the set period of time, then shut off. The factory setting is on
and set at 4-1/2 minutes.
LOCK
The LOCK feature is designed to prevent activation of the garage door opener from remote controls
while still allowing activation from the door control and keyless entry. This feature is useful for
added peace of mind when the home is empty (i.e. vacation).
MAINTENANCE ALERT SYSTEM (MAS)
This feature assists the homeowner in ensuring the garage door opener system stays in good
working condition. The MAS feature MUST be activated at time of installation. The factory setting
is off. The service LED will come on after 4500 garage door opener cycles. This indicates the
garage door opener may need maintenance; contact your installation dealer. If the MAS feature is
activated, the command LED (yellow) and the service LED (red) will alternate flashing back and
forth.
TIMER-TO-CLOSE (TTC) FOR MODEL 881LM ONLY
DO NOT enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors.
The TTC can be set to automatically close your garage door after a specified period of time (1, 5,
or 10 minute intervals). The garage door opener will beep and the lights will fl ash before closing
the door. If the door encounters an obstruction while closing, the garage door opener will make a
second attempt to close the door. If the obstruction has not been cleared after the second attempt,
the garage door opener will reverse open, stop and WILL NOT close until the obstruction has been
cleared. TTC WILL NOT work if the garage door opener is operating by battery power or if the
safety reversing sensors are misaligned. This feature is NOT intended to be the primary method of
closing the door. A keyless entry should be installed in the event of an accidental lock out when
using this feature.
