NOTE: This accessory must be used for all MyQ
installations and all other installations where the closing
force as measured on the bottom of the door is over 400 N
(40 kgf).
S
PECIAL NOTE: Merlin strongly recommends that The
Protector System
TM
be installed on all garage door
openers.
THE PROTECTOR SYSTEM
TM
(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 9
of the troubleshooting section).
Assembly Process:
The IR Beams are supplied preassembled, complete with two
sensors, wiring and wall brackets.
Install the mounting brackets and sensors to either side of the
inside of the garage door, and at a height of no greater than
100 mm off the garage floor.
The brackets are designed to be used for Wall or Floor fixing,
with a variety of
hole combinations to achieve the desired
results (fig 1).
Drill the required holes and install the brackets with wall plugs
and screws provided. Ensure they do not obstruct the door
movement.
Align the Sensors to face each other and tighten if necessary.
The wiring should exit from the bottom of the housing to
maintain the correct IP rating and continued operation.
One sensor is a Sending Eye , the other is a Receiving Eye. Try
to avoid positioning these in direct sunlight as this may interfere
with the operation of the beams.
Install Cabling:
Run both sets of IR Beam cables up the door tracks, across the
header wall to the centre, and back to the Power Head (see fig
2, 3 & 4).
Clean the contact area with alcohol wipes (provided) and
secure the self-adhesive Cable Mounts to the rails. Attach the
cable with cable ties.
Ensure the cable is well supported and does not interfere or get
damaged by movement of the door panels or spring hardware.
