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 Timer-to-Close feature automatically closes the door after a specified time period that can be
adjusted using the door control. DO NOT enable TTC if operating a one-piece door. TTC is to be used
ONLY with sectional doors. Factory default is set to off. The garage door opener will beep and the lights
will flash before closing the door. The TTC feature will deactivate if the garage door encounters an
obstruction twice; or the safety reversing sensors are incorrectly installed. The garage door will reverse
open and WILL NOT close until the obstructions are clear or the safety reversing sensors are correctly
installed. When the obstruction has been cleared or the safety reversing sensors have been aligned, the
door will close when the garage door opener is activated. 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.

THE PROTECTOR SYSTEM
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 effect the opening cycle.
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. NOTE: Do not use halogen,
short neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use LED
bulbs as they may reduce the range or performance of your remote controls.
®
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 36 and 37.
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.
