Does this buzzer need to be driven?

No need to drive, you just need to connect the power and it will make a sound

Is the sound of this unit a Beep, Buzzer or Siren?

It's a beep. I used my mobile phone to take a picture of the sound made by connecting a 9V battery. You can turn it on to see if it meets your requirements.

What is the wire gauge size?

pretty small, maybe 18 or 20 awg. I connected to 18awg on a 28vdc 3amp system. and it works great.
