NOTE: This accessory must be used for all
installations where the closing force as measured
on the bottom of the door is over 400N (40kgf).
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.
Setting auto close (optional)
NOTE: The Protector System
TM
MUST be installed

The auto close feature will automatically close the
garage door after the preset time. The time can be
adjusted up to 180 seconds using the trim pot located
on the control board. Auto close can be disabled by
adjusting the trim pot to 0s.

unit, (do not walk through the beam during this time).
