CAUTION: If your garage has no pedestrian entrance door, an emergency access device should be
installed. This accessory allows manual operation of the garage door from outside in the event of a
power failure.
For additional protection we strongly recommend fitting of Photo Electric (P.E.) Beams.
In most countries P.E. Beams are mandatory on all automated garage doors. For a small
additional outlay Automatic Technology recommends that P.E. Beams be installed with the SecuraLift®
Trio Overhead Garage Door Opener.

in full view and free from objects such as cars and children/people. Make sure that the door has
finished moving before entering or leaving the garage.
DO NOT operate the SecuraLift® Trio Overhead Garage Door Opener when persons are
in or near the doorway. Children near an moving garage door must be supervised at all
times. Serious personal injury and/or property damage can result from failure to follow
this warning.
DO NOT allow children to operate the garage door opener. Serious personal injury
and/or property damage can result from failure to follow this warning.
Regularly check that the safety obstruction force is tested and set as per page
19 of this manual. Failure to follow this could result in serious personal injury
and/or property damage. This must be repeated at regular intervals and
adjustments made as required.
DO NOT disengage the SecuraLift® Trio Overhead Garage Door
Opener to manual operation with persons or any other objects,
including motor vehicles, within the doorway.
The SecuraLift® Trio Overhead Garage Door Opener is not
intended for use by young children or infirm persons. Children

Important Safety Instructions

Owner Installation Instructions SecuraLift® Trio Overhead Garage Door Opener 5
The garage door must be well balanced. Sticking or binding doors must be repaired by a qualified garage door
installer prior to installation of the SecuraLift® Trio Overhead Garage Door Opener.
Frequently examine the installation, in particular cables, springs and mountings for signs of wear, damage or
imbalance. DO NOT use if repair or adjustment is needed since a fault in the installation or an incorrectly
balanced door may cause injury. DO NOT attempt to repair the door yourself as hardware is under extreme
tension.
Remove or disengage all garage door locks and mechanisms prior to installation of
the opener.
Connect the SecuraLift® Trio Overhead Garage Door Opener to a properly earthed general
purpose 240V mains power outlet installed by a qualified electrical contractor.
Disconnect the power cord from mains power before making any repairs or removing
covers. Only experienced service personnel should remove covers from the SecuraLift®
Trio Overhead Garage Door Opener.
When using auto-close mode, a P.E. Beam must be fitted correctly and tested for
operation at regular intervals. Extreme caution is recommended when using auto-
close mode. All safety rules must be followed - see page 24 for full details.
In order for the SecuraLift® Trio Overhead Garage Door Opener to sense an
object obstructing the doorway, some force must be exerted. As a result the
object, door and/or person may suffer damage or injury.
If the power supply cord is damaged, it must be replaced by an Automatic
Technology service agent.
Make sure that the door is fully open before driving in or out of the
garage and fully closed before leaving the driveway.

Operation
To open or close the door simply press a button on a TrioCode™ handheld
transmitter, or optional wall switch for two seconds. During open and close cycles
the door can be stopped by pressing the button again. The next actuation will
move the reverse the door’s direction.
TrioCode™ Code Hopping Technology
Every time a TrioCode™ transmitter is used a new security code is generated from
over 4.29 billion possibilities. This greatly enhances the security of the system and
makes “code grabbing” a thing of the past.
These transmitters also overcome interference issues by simultaneously sending a
signal over three slightly different frequencies. Even if two of the three signals are
jammed, the third will communicate with the opener.
ALPS (Automatic Limits Positioning System)
ALPS does away with manual adjustment of the door’s limits position using mechanical
parts, such as cams and microswitches.
ISS (Intelligent Safety obstruction System)
While the opener is performing a close cycle, should the door hit an obstacle or be restricted
in some manner, it will automatically reverse. The amount of force the door should encounter
before reversing is automatically adjusted during the initial installation of the automatic door
opener. The door will also stop if restricted whilst opening. The safety obstruction force should be
checked at least once a month. See page 19 for instructions.
Security Code Store
The SecuraLift® Trio Overhead Garage Door Opener will store up to 14 different transmitters codes.
Overload Indicator
When the maximum opening and closing force capacity of the SecuraLift® Trio Overhead Garage Door
Opener is exceeded an audible beeper will sound to indicate that an overload has occurred.

Step 13 - Mounting Door Bracket
The door bracket comes in two parts. The bottom plate
with two mounting holes is used on its own for one piece
doors. For sectional doors, the top plate is placed over
the bottom plate and is fixed with four (4) screws (Fig. 22).
Mount the door bracket, or bracket assembly, on the
door’s centre line one-third down the top panel (Fig.
22) using M6 or equivalent screws (not supplied),
STEEL DOORS ONLY: Bracket can be welded on.
NOTE: If in doubt about the door’s strength,
reinforcement may be added to the door’s
frame where necessary. Door damage may occur if the
bracket is installed on a panel with insufficient strength.
The opener’s warranty does not cover damage caused
to the door and/or door panels.
Step 14 - Attaching the Arms
FOR TRACK TYPE DOORS
Assemble the bent and straight arms with bolts and
nuts supplied in the accessory pack (Fig. 23). Always
use both bent and straight arms.
Connect the assembled arm to the bracket and the
disengaged trolley with clevis and snap pins.
WARNING: Connecting the bent arm other way
around may damage the door.

to learn the codes of any transmitters to be used with the
opener. Up to fourteen (14) codes can be stored in the
receiver’s memory.
Ensure that the battery is inserted into the
transmitter.
Press the CODE SET button and release. The
CODE SET LED will illuminate to indicate the
opener is in Code Learn mode. If a valid code is
not stored within 15 seconds the opener will exit
Code Learn (Fig. 30).
Press the transmitter button (one of four) that you
want to control the door. The CODE SET LED will
begin to flash.
Press the same transmitter button again. The CODE
SET LED will illuminate for one second and then go
out.
The transmitter is now coded to operate the door
- press the button to test.
Step 17.2 - Setting the Transmitter to Operate
the Courtesy Light
Although the courtesy light comes on with each operation
of the opener, it may also be controlled by a transmitter
without operating the door.
Press the CODE SET button twice. The CODE SET
LED will illuminate and the courtesy light will turn on
to indicate that the light code learning is active (Fig.
31).
Choose a transmitter button not already coded into
the receiver. Press this button and the CODE SET
LED will begin to flash.
Press the same transmitter button again. The CODE
SET LED will illuminate for one second and then go
out.
The transmitter is now coded to operate the light -
press the button to test.
