Narrative:
On approach to our destination we got an evacuate/evacuation alarm in the cockpit and could hear it in the cabin as well. I was pilot flying; so I continued to fly the airplane. I took the radios as well while the captain addressed the issue. The interphone was unusable so we couldn't talk with the flight attendants right away. I continued to fly the aircraft to landing while the captain determined that nothing was wrong in the back at that time. We could only momentarily silence the evacuate/evacuation alarm with our button or by holding it in. Sometimes even holding it in wouldn't silence it. I landed uneventfully. It was very difficult to understand the taxi instructions due to the noise. On taxi-in the APU generator would not come online. The assigned gate did not have power. So we had to clear equipment and move over to the next gate. On the ground; the emergency call sounded. We didn't know if the flight attendants were trying to communicate something new to us. The captain stopped and directed me to go ahead and look through the peep hole and then crack the door to see if all was still ok. All was ok. We parked at the new gate. Evacuate/evacuation horn kept going off until maintenance came on board and pulled several cbs. It would not have been prudent to get into the books at the phase of flight we were and considering this particular situation.
