This is the last 2120 panel left in our area and they are getting ready to upgrade so this is my last chance to do something on it. In this video I give a general overview on the basics of how this system works and how it's programmed. If you has learned on this system, all of newer panels would be easy to understand as the 2120 set the platform for SMPL programming that is the language all Simplex panels use.
Please leave a comment if you have worked or still work on any of these. It would be interesting to know how many are still left.
I know the young technicians will disagree but this was my favorite panel.
