The FAAC XT2 is a modern 2-channel remote equipped with 2 push buttons. The remote is self-learning (from remote to remote). Alternatively, you can program the remote directly on the receiver. The encrypted rolling code makes for secured use; 66-bit encryption allows for the generation of more than 73 trillion unique codes at the moment of transmission.
The addition 'LR' to the serial number means 'Long Range' These are the same remotes as those without the 'LR' addition, but they have greater reach.
