Narrative:
CRJ1 on vector 110 degrees, DC9 on 360 degrees. Went on to make a handoff and to check on other aircraft to climb on course. Conflict went off between the 2 aircraft. I took action to correct problem. Supplemental information from acn 532404: aircraft Y on a vector to join the kekee arrival to dayton approach. Aircraft X on vector to departure cvg sebound. At 12000 ft, TCASII goes off as aircraft X climbs through altitude of aircraft Y. Both aircraft turned to the left. Supplemental information from acn 532403: I was working coordinator. I heard the departure south controller issue a left turn to tsry. I observed the situation, but was on the landline making a handoff to the center.

Narrative: CRJ1 ON VECTOR 110 DEGS, DC9 ON 360 DEGS. WENT ON TO MAKE A HDOF AND TO CHK ON OTHER ACFT TO CLB ON COURSE. CONFLICT WENT OFF BTWN THE 2 ACFT. I TOOK ACTION TO CORRECT PROB. SUPPLEMENTAL INFO FROM ACN 532404: ACFT Y ON A VECTOR TO JOIN THE KEKEE ARR TO DAYTON APCH. ACFT X ON VECTOR TO DEP CVG SEBOUND. AT 12000 FT, TCASII GOES OFF AS ACFT X CLBS THROUGH ALT OF ACFT Y. BOTH ACFT TURNED TO THE L. SUPPLEMENTAL INFO FROM ACN 532403: I WAS WORKING COORDINATOR. I HEARD THE DEP S CTLR ISSUE A L TURN TO TSRY. I OBSERVED THE SIT, BUT WAS ON THE LANDLINE MAKING A HDOF TO THE CTR.
