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).

PECIAL NOTE: Merlin strongly recommends that The
Protector System
TM
be installed on all garage door
openers.
IR BEAMS:
By installing IR Beams, an open door is prevented
from closing if a person or object is located in the beam area. If
the door is already closing, it will return to the open position. A
closed door is not prevented from opening.
If the Protector System
TM
is installed and needs to be removed,
the opener will need to be reprogrammed (refer to paragraph 4
of the troubleshooting section).
NOTE: A complete set of installation and setup
instructions are supplied with the accessory item.
Figures 1, 2 and 3 show recommended assembly of bracket(s)
and "C" wrap based on the
wall
installation of the sensors on
each side of the door shown above, or on the
door tracks
themselves. Figure 4 shows variations which may fit your
installation requirements better.
Make sure the wraps and
brackets are aligned so the sensors will face each other
across the door.
• Connect each assembly to a slotted bracket, using the
hardware shown.
Note alignment of brackets for left and
right sides of the door.
Finger tighten the lock nuts.
• Use bracket mounting holes as a template to locate and drill
two (4.8 mm) diameter pilot holes on both sides of the door so
that the beam mounting height is no greater than 100 mm
above the floor.
• Attach bracket assemblies with carriage bolts as shown.
• Adjust right and left side bracket assemblies to the same
distance out from mounting surface. Make sure all door
hardware obstructions are cleared. Tighten the lock nuts.
• Centre each sensor unit in a "C" wrap with lenses pointing
toward each other across the door.
• Secure sensors with the hardware provided. Finger tighten
the wing nut on the receiving eye to allow for final adjustment.
Securely tighten the sending eye wing nut.
• Run wires from both sensors to the opener and connect the
two white only wires to terminal (2) and the black/white wires
to terminal (3) on your opener.
