The police are the ones who should be serving him, not your friend. Who told you a friend had to serve it?
The order also requires him to have no contact with you, correct? The advantage of the order is that the police are REQUIRED to arrest him for ANY violation, not just acts that are crimes. So he can be stopped before simple contact escalates to something more serious.
I'd suggest calling your local women's shelter and talking with an advocate to make a safety plan. Also, the order will protect you only to the extent you are willing to report any violations. Be sure you do so EVERY time. It isn't unusual for an abuser to test the waters to find out if you're serious.
