“unexpected consequence”.... two words often used in humanity's story.

That regulation may relate to a very unique touch-button system used by Otis for a while at a time when modern electronics didn't even exist. It had the unexpected consequence of being triggered by the ionised air of a fire and tended to call the lift to the floor that was on fire and hold it there.

Very interesting teardown. I'd heard that elevator buttons were carefully designed to not trigger when exposed to fire. A burning elevator travelling to each floor of a building is somewhat discouraged. Guess that explains the robustness, huge antitracking slots and intervening fins. Thanks for the videos, really enjoy your style.
