The button modules are universal going into a car module which is then decoded to tell what level has been pressed which we swapped to another level and it didn't work, we also changed the car module that each floor goes into didn't help. I am going to see on Monday if the floor will work on phase 2 to confirm if it is on security and maybe the I/o is misaddressed for the 7th landing. I will also recheck the car module wiring.
