Narrative:

[Aircraft Y] was on a practice VFR ILS 24 approach at about a 5 mile final and was instructed to break off the approach and make a right 360 to follow [aircraft X]. [Aircraft X] was on a 6 mile final for a visual approach. The helicopter [aircraft Y] was breaking off the approach and flying to the northeast north of the 24 approach course. [Aircraft X] received a traffic alert saying the traffic was 200 feet below so they began to climb. The helicopter was north of the approach course at that time. Break the helicopter approach off sooner and do a wider 360 so the TCAS does not go off in [aircraft X].
