They are different panels. The detection works much the same way and pretty sure is compatible for the most part, but the original twinflex was much more basic. It didn't have a display or full keypad. Codes are different also. The original panel was made by Rafiki but as I understand it Fike took them over and re-developed the panel. We have some jobs that still have the old original. I'll try to make a video when we next visit but it may be a few months. There is also a twinflex pro 2 🤯
