Installation
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).
SPECIAL NOTE: Merlin strongly recommends that The Protector
System
TM
be installed on all garage door openers.
SAFETY BEAMS:
By installing Safety 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 .
Assembly Process:
The Safety 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 Safety Beams 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 Safety Beam cables up the door tracks, across the
door header and back to the Power Head (see fig 2 & 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.
INSTALLING THE BRACKETS
Be sure power to the opener is disconnected.
Install and align the brackets so the safety reversing sensors will face each other across
the garage door, with the beam no higher than 3.9" (10 cm) above the floor. Choose one of the following installations.
