Operation
Features
Your garage door opener is equipped with features to provide you with greater control
over your garage door operation.
Alert2Close
The Alert2Close feature provides a visual and an audible alert that an unattended door is
closing.
TIMER-TO-CLOSE (TTC)
The TTC feature automatically closes the door after a specified time period that can be
adjusted using a TTC enabled door control (Models 881LMW or 880LMW). Prior to and
during the door closing the garage door opener lights will flash and the garage door
opener will beep.
®
MyQ
MyQ allows you to control your garage door opener from your mobile device or computer
from anywhere. MyQ technology uses a 900Mhz signal to provide two way
communication between the garage door opener and MyQ enabled accessories.
The garage door opener has an internal gateway that allows the garage door opener to
communicate directly with a home Wi-Fi®network and access your MyQ account.
THE PROTECTOR SYSTEM®(SAFETY REVERSING SENSORS)
When properly connected and aligned, the safety reversing sensors will detect an
obstruction in the path of the infrared beam. If an obstruction breaks the infrared beam
while the door is closing, the door will stop and reverse to full open position, and the
opener lights will flash 10 times. If the door is fully open, and the safety reversing
sensors are not installed, or are misaligned, the door will not close from a remote control.
However, you can close the door if you hold the button on the door control or keyless
entry until the door is fully closed. The safety reversing sensors do not affect the
opening cycle. For more information see page 19.
ENERGY CONSERVATION
For energy efficiency the garage door opener will enter sleep mode when the door is fully
closed. The sleep mode shuts the garage door opener down until activated. The sleep
mode is sequenced with the garage door opener light bulb; as the light bulb turns off the
sensor LEDs will turn off and whenever the garage door opener lights turn on the sensor
LEDs will light. The garage door opener will not go into the sleep mode until the garage
door opener has completed 5 cycles upon power up.
LIGHTS
The garage door opener light bulbs will turn on when the opener is initially plugged in;
power is restored after interruption, or when the garage door opener is activated. The
lights will turn off automatically after 4-1/2 minutes. An incandescent A19 light bulb
(100 watt maximum) or for maximum energy efficiency a 26W (100W equivalent)
compact fluorescent light (CFL) bulb may be used.
Light Feature
The garage door opener is equipped with an added feature; the lights will turn on when
someone enters through the open garage door and the safety reversing sensor infrared
beam is broken. For added control over the light bulbs on your garage door opener, see
page 34.
USING YOUR GARAGE DOOR OPENER
The garage door opener can be activated through a wall-mounted door control, remote
control, wireless keyless entry or MyQ®accessory. When the door is closed and the
garage door opener is activated the door will open. If the door senses an obstruction or
is interrupted while opening the door will stop. When the door is in any position other
than closed and the garage door opener is activated the door will close. If the garage
door opener senses an obstruction while closing, the door will reverse. If the obstruction
interrupts the sensor beam the garage door opener lights will blink 10 times. However,
you can close the door if you hold the button on the door control or keyless entry until
the door is fully closed. The safety reversing sensors do not affect the opening cycle.
The safety reversing sensor must be connected and aligned correctly before the garage
door opener will move in the down direction.
BATTERY BACKUP*
The battery backup system allows access in and out of your garage, even when the
power is out. When the garage door opener is operating on battery power, the garage
door opener will run slower, the light will not function, the Battery Status LED will glow
solid orange, and a beep will sound approximately every 2 seconds.
