First of all, the researchers were testing a specific fire alarm system for the company that made it. So it had to be a fire alarm.

Secondly, this new fire alarm detected the actual location of the fire and reported it. That's a lot more specific than just "fire, fire, fire"

I'm pretty sure that if I heard a voice on a speaker say, "Fire has been detected in room 245, please evacuate the building immediately" I would stand up and leave.
