@[email protected] I spent many late night hours in my early teens (1980s) hanging out at a major newspaper facility (my mom often worked late in the art department) so I knew the second shift editors and press operators and how most of the place worked. The senior editors had a button near the city desk and the wire teletypes that would ring a really loud bell in the pressroom, this would notify them to stop the presses as a new front page is being prepared. If in such situations someone else was nearer the button, the editor would aways yell the line at them.
