The FAAC 868 SLH series is a patented 868MHz radio-control system which combines self-learning duplication with an encrypted rolling code. This system offers greater protection against unwanted intrusion than a fixed-coding system whilst retaining the simplicity of self-learning. Each 868SLH transmitter and decoder has a site code. Once a transmitter (with a valid site code) had been recognised by the decoder, the rolling code portion of the code is checked and then changed according to a complex algorithm, synchronised with data stored by the receiver. A decoding board which has learned a site code will recognise only transmitter characterised with that code. The decoding board will automatically recognise and new "friendly" transmitter simply by activation the transmitter twice. A transmitter may be either "master" or "slave". Only a master can transfer its site code to another transmitter or decoder. All transmitters are master when new.
