Narrative:
Aircraft X was put into position on the runway and appropriate traffic calls were made. Aircraft Y landed on an intersecting runway and was told to turn right at taxiway and hold short of the runway for the departing traffic. The pilot read back the instructions and complied. Aircraft X was cleared for takeoff. On departure roll the asde-X alarmed and displayed a conflict between aircraft X and aircraft Y. I observed aircraft Y holding short of the runway; stationary; as instructed. Aircraft X departed safely. The asde-X alarmed in error and should be checked for accuracy to ensure it is operating correctly.
