INSTALL THE PROTECTOR SYSTEM™ (IR BEAMS) OPTIONAL ACCESSORY
17
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.
ENABLING THE PROTECTOR SYSTEM:
• Connect the IR Beam wiring to the opener and turn ON. (The Protector System will automatically enable
once they are connected and will now operate in a FAIL SAFE mode.)
DISENABLING THE PROTECTOR SYSTEM:
If the Protector System is installed and needs to be removed the opener will need to be reprogrammed.
Perform the power ON/OFF sequence as follows.
• Remove the IR wires from the opener.
• Turn the mains power OFF for 5 seconds.
• Turn the power ON for 5 seconds.
• Turn the power OFF for 5 seconds.
• Turn the power ON and check the opener operates OK without the IR Beams.
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.
Timer to close feature (TTC)
Auto close is NOT recommended for households with young children.
TIMER TO CLOSE feature: (TCC) 10 to 180 seconds.
NOTE: IR beams must be installed before TTC will operate.
The Timer to Close feature allows the door to automatically close after a specified time period. During the
OPEN door waiting period, the courtesy light will flash continuously.
If the door encounters an obstruction while closing, the opener will return to the OPEN position and the
waiting period will begin again.
To activate the Timer to Close.

• Press and Hold both "P" and "DN" buttons for 3 seconds. When the
Courtesy light flashes "TWICE", release both buttons.
• Press the "UP" for each 10 second interval required for
Timer to Close. A "BEEP" will register for each press. "DN" button
will reduce the count if needed.
• Press and release the "P" button to accept this setting.
To Deactivate the Timer to Close.
• Start with the door fully CLOSED.
• Press and Hold both "P" and "DN" buttons for 3 seconds. When the
Courtesy light flashes "TWICE", release both buttons.
