NOTE: This accessory must be used for all
installations where the closing force as measured
on the bottom of the door is over 400 N (40 kgf).
After the opener has been installed and adjusted, the
Protector System™ accessory can be installed.
Instructions are included with this accessory.
The Protector System™ provides an additional
measure of safety against a small child or animal
being trapped under a garage door. It uses an infra-
red beam, which when broken by an obstruction,
causes a closing door to open and prevents an open
door from closing and is strongly recommended for
homeowners with young children.
NOTE: The opener will automatically detect the
Protector System
TM
when it is installed and
operating for 5 minutes (during this time the beams
must remain unobstructed). The opener will not
close unless the beams are aligned
.

SAFETY FIRST!
Whilst Chamberlain have engineered safety features into your garage door opener, we urge you to consider fitting
IR Beams to your new garage door opener. In many countries these devices are compulsory to assist in
preventing serious injury or property damage. For your own peace of mind and the safety of others please install
this inexpensive safety device.
Door may operate unexpectedly, therefore do not allow anything to stay in the path of the door.

Timer to close feature (TTC)
The Timer-to-close feature allows the door to automatically close after a specified time period. Prior to the door
closing, the garage door opener lights flash for 8 seconds before the door begins to close.
If the door encounters an obstruction while closing, the opener will make a second attempt to close the door. If
an obstruction occurs on the second attempt, the garage door opener will open, stop and WILL NOT close until
the obstruction has been cleared and the opener has been operated again.
