Specifications

Most current garage door openers operate on a single 433MHz
frequency with a wide reception bandwidth. Unfortunately many
other household products also operate on the same frequency.
Every day items like baby monitors, door bells and some domestic
and in car wireless entertainment systems. And they don’t have
to be in your home. They can be in your neighbours home.
If one of these items is being used in your area, or is malfunctioning,
it has the potential to interfere with the operation of your garage
door opener. You will push the button on your opener transmitter,
and nothing will happen. This can be very frustrating, when
you need your door to open/close, and it won’t.
To overcome this problem, which while localised is on the
increase, all new B&D Controll-A-Door openers now feature
unique Tri-Tran multi frequency operation. Tri-Tran has an
automatic frequency change function, with each of its three
frequencies transmitted having a much tighter bandwidth.
The frequency changes every 22mS during a transmission
and reception. So if there is another signal interfering on
a part of this frequency spectrum, the automatic change
ensures the signal still reaches the opener. This makes
Tri-Tran up to one thousand times better, in terms of
in band interference rejection, than a typical FM
receiver, and up to a million times better than
some AM receivers.
To ensure your garage door opener works when you need
it to, insist on an opener with Tri-Tran. The world’s first
multi-frequency garage door opener technology.
B&D’s Tri-Tran multi frequency technology,
means your opener will never have interference
from household wireless products including
baby monitors, door bells and some in home
and in car wireless entertainment systems or
other electronic devices. So when you want
your garage door to open, it will.
