Panel Lift Garage Door Openers
What is Tri-Tran?
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.
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, the all new, Australian designed, 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 needed, install a Controll-A-Door opener with Tri-Tran. The world’s first multi-frequency garage door opener technology.
