ADJUSTMENT SECTION
INSTALLING OPTIONAL OBSTRUCTION DETECTION BEAMS
21
To prevent entrapment, install The
Protector System™ (IR Beams) no higher
than 100 mm above the floor.
Disconnect power to the garage door
opener before installing The Protector
System™(IR Beams)
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).
SPECIAL NOTE: HomEntry strongly recommends that the
obstruction detection beam be installed on all garage door
openers.
Obstruction detection beams:
By installing the obstruction
detection 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 obstruction detection beams are installed and needs to be
removed, the opener will need to be reprogrammed (refer to
paragraph 4 of the troubleshooting section).
Assembly Process:
The obstruction detection beams are supplied preassembled,
complete with two sensors, wiring and wall brackets.
(figure 1 &
figure 2)
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 (view 1) or Floor
(view 2) fixing, with a variety of hole combinations to achieve the
desired results.
Drill the required holes and install the brackets with wall plugs and
screws provided. Ensure they do not obstruct the door movement.
Wiring Process:
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.
Run both sets of wire back to the power head CONTROL PANEL
(refer page 5). Ensure the wire is well supported and does not
interfere or get damaged by movement of the door panels or
spring hardware.
Disconnect Power from the Unit:
At the power head end, cut the wires to the correct length and strip
each back around 10 mm.
Twist both
White
wires together and install into “quick release”
terminal 2 (white)
(fig 3)
Twist both
Black/White
wires together and install into “quick
release” Terminal 3 (Grey) (fig 3)
(The sensors are a 2 wired system connected in a parallel
configuration).
Reconnect Power to the Unit:
When aligned correctly the Red LED on each sensor will remain
“ON”
constantly.
If incorrectly aligned both LED will
“flash”
.
Correct the alignment if necessary.
The opener is now ready to be checked for correct obstruction
detection beam operation.
Note: Refer to installation and test instructions as included in
the obstruction detection beam kit.
