After takeoff in ZZZ; received a 14th stage right duct warning. Shortly after we received 'Jetpipe overheat.'  We turned right and stayed in the pattern and returned to ZZZ to land. I ran the 14th Right Duct checklist. I queried the Captain about declaring an emergency; but he told me we had 'priority handling' and that he didn't see the need. We went back to the gate and deplaned. According to Maintenance; the right engine was new and the wiring for the fire loops was creating friction and causing the sensors to alarm. Better training [recommend] for Maintenance. One of the Mechanics said a smell that the Flight Attendant pointed out during her preflight was 'normal.' It wasn't; and this whole situation could have been avoided; had the mechanics took their time to analyze what was going on. Staffing is a huge issue in ZZZ the ground crew told us they were not prepared or staffed to handle an emergency situation. I would not feel comfortable having an emergency in ZZZ based on this experience with the current level of staffing.
CRJ200 First Officer reported a precautionary air return due to fire loop sensor malfunction.
