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™ (IR Beams) accessory can be
installed. Instructions are included with this accessory.
The Protector System™ (IR Beams) 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.
Installing and adjusting:
• Close the garage door.
• Turn the opener off.
• Install the Protector System
TM
(IR Beams) using the
brackets, wires and instructions provided with the
product.
• Twist the two white (only) wires together and
terminate them into the white “safety beam” terminal.
Twist the two white/black wires together and
terminate them into the grey “safety beam” terminal.
• Ensure the trim pot on the opener is set to 0s.
• Turn the opener on.
• Allow 5 minutes for the beams to self-learn to the
unit, (do not walk through the beam during this time).
• Adjust the trim pot to the desired closing time.
NOTE: The opener will automatically detect the
Protector System
TM
(IR Beams) 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.
