What he gave you is called a glass break sensor. That will activate the alarm if a window is broken. What you want is called a proximity sensor with windows. When you hook this up and tie it in so it protects the windows as well, then when a window or sunroof is open and someone sticks there hand through it, the alarm will go off.
