Warranty
Five (5) year/10,000 cycles full parts and labour
warranty on motor, electronics and mechanical
components of the opener when installed by a
B&D Dealer (conditions such as annual garage
door servicing apply, refer to Section 11.3.b.i for
information)
Tri-Tran Frequency Hopping Technology
Every time a transmitter is used, it simultaneously
sends a signal over three different frequencies,
reducing the chance of interference from other
radio frequency sources.
Code Hopping Technology
Every time a transmitter is used a new security
code is generated from over 4.29 billion possible
code combinations. This greatly enhances
the security of the system and makes “code
grabbing” a thing of the past!
Multi-Channel Transmitter
Multi-channel transmitters allow you to operate
other devices such as an adjoining garage door
or automated gate from the same handy unit.
Safety Reversing System
The automatic safety reverse system significantly
reduces the risk of death or serious injury if
trapped by a closing door. The safety reverse
force can be adjusted for environmental
conditions such as windy areas.
Memory Retention
In case of a power failure the opener does not
lose the transmitter codes or limit settings.
Soft Start/Soft Stop
The opener eases into and out of each cycle
making for smoother and quieter operation, as
well as reducing wear and tear on the door and
opener.
Manual Release
The manual release handle allows the door to be
operated by hand in the event of a power failure.
Self Locking
There is no need to manually lock your garage
door, as the opener ‘positively’ locks the door
when closed.
Service Indicator
The opener has a built in service counter. From
factory this is loaded with 3000 cycles. When this
counter expires, the service yellow LED will light
up and at the start of each door movement the
beeper will sound three times. After opening or
closing the door the courtesy light will flash and
beeper sound five times. Contact your dealer/
installer for service. (Refer to Section 10.5 for
information).
Service Fault Indicator
Flashing LEDs on the control panel easily identify
operational problems or service requirements.
Dynamic Door Profiling
Changing door characteristics are automatically
compensated for and “learnt” with each
operation of the door.
Courtesy Light
The courtesy light automatically switches on for
approximately three (3) minutes when operating
the door. This can also be programmed to turn
on and off from a transmitter. (Refer to Section
8.2 for information).
Vacation Mode
A transmitter can be programmed to disable
the garage door opener radio receiver. This is
ideal if the door is to be left idle for prolonged
periods. (Refer to 8.3 for information)
Pet (Pedestrian) Mode
A transmitter can be programmed to open
the door partially to allow pets access to the
garage. The door opening height is adjustable
via a handheld programmer (contact your
dealer for further information).
