Yeah I don’t see why a conventional panel couldn’t handle elevator recall as easily as an addressable panel could (it would probably just be somewhat-more complex).
They sorta would, but I’d say that the ideal setup would be having both in place: a fire alarm system to alert both occupants & the fire department & tell the former to evacuate, & a fire sprinkler system to help control (& maybe even outright extinguish) any fire that breaks out.
