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

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.

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.
