The alarms were safety hardware interlocks. Nobody asked why and found the UI bugs that was causing this. The hardware interlocks were removed because the system had been working safely for so long. This was really feedback - nobody informed the developers that safety hardware interlocks were locking all the time.
Edit: see replies, originally I wrote fuses, but hardware interlocks is more correct.
