The fire dept doesn't just run up the stairs, they check the firepanel which tells them what floor the fire device was activated on first. All the floors in the stairwell are clearly identified as well, they aren't relying on a fireman carrying a bunch of equipment to have to worry about counting floors as they run up the stairs. Truth be told, they won't even take the stairs most of the time, they will take the firemans elevator up to a floor or two below the point of activation and then take the stairs the last leg. In the case of a medical emergency the elevator will take them to whatever floor the caller told them they are on be it 4,13 or whatever.... Don't get me wrong I'm all for the change, just think the reasoning isn't sound, let just be honest and say it's to keep marketers from tricking suckers.
