Narrative:
Dfw tower had me #2 for 17R behind air carrier 1. Dfw approach had cleared me for a visual. Then the approach pulled me out of sequence on account of my speed with a heading of 100 degrees. Put air carrier 2 for landing. Approach asked me if I had air carrier 2 visual. I did, and told them yes. Approach then cleared me for the visual again, to keep air carrier 2 in sight. When I turned back to the landing pattern, air carrier 2 advised tower his TCASII went off. Tower then advised me to land (cleared). I believe if the controller had not pulled me out of sequence, this would have never happened. I followed the controller's directions. Air carrier 2 complained to approach control of the TCASII going off.

Title: AN ATX LTT STATES THAT HE SET OFF AN ACR'S TCASII WHILE TRYING TO FOLLOW TWR'S INSTRUCTIONS.
Narrative: DFW TWR HAD ME #2 FOR 17R BEHIND ACR 1. DFW APCH HAD CLRED ME FOR A VISUAL. THEN THE APCH PULLED ME OUT OF SEQUENCE ON ACCOUNT OF MY SPD WITH A HDG OF 100 DEGS. PUT ACR 2 FOR LNDG. APCH ASKED ME IF I HAD ACR 2 VISUAL. I DID, AND TOLD THEM YES. APCH THEN CLRED ME FOR THE VISUAL AGAIN, TO KEEP ACR 2 IN SIGHT. WHEN I TURNED BACK TO THE LNDG PATTERN, ACR 2 ADVISED TWR HIS TCASII WENT OFF. TWR THEN ADVISED ME TO LAND (CLRED). I BELIEVE IF THE CTLR HAD NOT PULLED ME OUT OF SEQUENCE, THIS WOULD HAVE NEVER HAPPENED. I FOLLOWED THE CTLR'S DIRECTIONS. ACR 2 COMPLAINED TO APCH CTL OF THE TCASII GOING OFF.
