What is Tri-Tran+™

What is Tri-Tran+™

Tri-Tran™128 is a revolutionary new coding system that provides enhanced reliability and security by using three frequencies to overcome interference issues. So when you want your garage door to open, it will.

Tri-Tran+™ transmitters also use code hopping technology to generate a new random code from over a trillion, trillion possibilities with each use. You can rest assured with these odds that only your transmitters will securely open your garage door.

Why do I need Tri-Tran+™

Why do I need Tri-Tran+™

Increasingly our environment is filled with wireless devices such as cordless headphones, wireless sound systems and more, many of which operate on the same frequencies as door and gate openers. Frustratingly, these devices can jam out your door or gate opener’s receiver, and the offending device may not even be in your building, it could be over 200 metres away.

Tri-Tran™128 overcomes this challenge by simultaneously transmitting on three different frequencies. Even if two frequencies are jammed, the Tri-Tran™128 transmitter will still operate your door. Tri-Tran™128 is your insurance that your garage door will continue to operate without interference for years to come, no matter what new technology is introduced to the surrounding area.
