Procedure: Place a 40mm obstacle (1) laid flat on the floor under the garage door. Operate the door in the down
direction. The door must reverse upon contact with the obstacle. If the door stops on the obstacle, remove
obstacle and repeat setting the limits and force sections 21 & 22 and repeat safety reverse test.
When the door reverses on the 40mm obstacle, remove the obstacle and run the opener through a complete
travel cycle. Door must not reverse in closed position. If it does, repeat setting the limits and force sections 21 &
22 and repeat safety reverse test.
Repeat test once a month and adjust as needed.

Connecting the Protector System
TM
Locate the terminals on the front of the opener. Strip all
wires back about 10mm then twist the two white wires
and the two white/black wires together. Trim the twisted
wires to approximately 6mm. Use a small screwdriver or
pen to hold down the spring terminals, insert the
white/black wires into the grey terminal (4), then
terminate the white (only) wires into the white terminal
(3).
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 prevent serious injury or property
damage. For your own peace of mind and the safety of others
please install this inexpensive safety device.

STANDARD INSTALLATION COMPLETE
Install this accessory for all installations on tilt
doors, doors over 2.5m and when the closing force
as measured on the bottom of the door is over
400N (40kg).
After 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 obstacle
being caught under a garage door. It uses an
invisible 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.
The safety reverse system test is important. The garage door must reverse on contact with a 40mm
obstacle laid flat on the floor. Failure to properly adjust opener may result in serious personal injury
from a closing garage door.
