Then again I'm not 100% sure why the older code allowed "bypass" operation. Could've just been a different time where people still smoked in buildings and elevators and nuisance alarms going off could've caused the elevators to go into phase one frequently enough they wanted a way to bypass it. Or people were a little more accountable back then (the if you got hurt it was your fault old school mindset) and it didn't seem unsafe so why change it. I wasn't around back then so I can only speculate.
