If the fire alarm goes off at the mall, does it go off at the places you need to enter from outside (Old Navy, Hometown Buffet, David's Bridal, and Carhartt)?

Sure it would and the emergency lights would go off to guide u

Yes

Why?

You will be directed where to go

I Don't think so but the stores will.direct you if that does happen

You will need to follow the "Exit" signs and listen to the directions of the Mall administration and security.

If not, I would assume security would evacuate those places as well.
