The ones in my home have a test button (for what purpose I'm unsure).
They are also run off my home electricty (so they do exist). This
type is also supposed to be "gangable" so if one goes off, they
all go off (that can be real annoying in some situations). I don't
think the electricians wired my house to take advantage of that
feature though.
I believe Home Depot carries them.
