PRODUCT FEATURES

OPERATION
To open or close the door simply press the hand held transmitter, the wall mounted transmitter, or optional wall
switch. During an open or close cycle the door can be stopped by pressing the button while the door is in motion.
The next actuation will move the door in the opposite direction.

SecruaCode® HOPPING CODE TECHNOLOGY

Every time a SecuraCode® transmitter is used, it generates a new access code from 4.29 billion possibilities. This ran­dom process makes it is near impossile for unwanted operation of your Cobra® Overhead Garage Door Opener.

AUTO CALCULATE THE LIMITS AND SAFETY FORCE
During installation, after setting the open and close positions with your SecuraCode® transmitter, the Cobra® Over-
head Garage Door Opener automatcially measures the force required to move your door. These travel limits and the
safety force will be stored in the memory. Also, the current door position will be remembered during a power failure
or if the door is moved manually.

SAFETY OBSTRUCTION SYSTEM

Should the door contact an obstacle or be restricted in any manner while closing it will automatically reverse. This
level of safety force is automatically calculated when the Cobra® Overhead Garage Door Opener is initially installed.
The door will also stop if restricted whilst opening. The Safety Obstruction Force should be checked at least once a
month.

AUTO COURTESY LIGHT

A SecuraCode® transmitter button can be programmed to independantly operate the courtesy light. The courtesy
light also turns on with any door operation, shutting off after an adjustable specifi ed time.

VACATION MODE

A SecuraCode® transmitter can be programmed to lock and unlock all other transmitters programmed into the
openers’ memory. This will prevent any transmitter other than the programmed one from opening the door, stop­ping unauthorised access while you are away.

PET (PEDESTRIAN) MODE

A SecuraCode® transmitter button can be programmed to partially open the door for a pet to enter or exit the
garage at any time. The door opening position is also programmable so that the door can be opened to a suitable
height for pedestrian access.

AUTO-CLOSE

The Cobra® Overhead Garage Door Opener can be programmed to automatically close after the door is fully
opened. The auto close time is adjustable. The Photo Electric Beam must be installed to prevent the door closing
when an obstruction may still be present, thus causing personal injury or damage to property.

PHOTO ELECTRIC BEAM

The Cobra® Overhead Garage Door Opener has an input for a Photo Electric Beam to be connected for extra safety
protection as well as ustilisation of the auto-close mode.

ALARM / STATUS OUTPUT
An external alarm may be toggled on/off by pressing the SecuraCode® transmitter button. If the alarm function is
not used the alarm output can function as a Door Status output.

MANUAL OPERATION
If the power to the Cobra® Overhead Garage Door Opener is disrupted for any reason, the door can be disengaged
by pulling down on the string handle on an angle towards the door. This will allow you to manually open or close the
door. To re-engage the opener pulls the string handle away from the door.

STANDBY (Power Save) MODE
If the Cobra® Overhead Garage Door Opener is left for fi ve minutes without any button presses, the unit will enter
standby mode. The decimal point indicator on the display will turn on. The unit will continue usual operation. When
the next button press occurs the display will again turn on.
