A sensor system for an automatic sliding door employs multiple sensor modules. Each of the sensor modules includes both a presence sensor and a motion sensor. In addition, each of the sensor units includes switches for adjusting the size of the presence zone, for selecting either a continuous or a triggered scan mode and for selecting an operating phase to prevent interference. The sensor units are generally mounted above the threshold of the doorway and their opeations are synchronized to provide both a traffic sensor and a safety sensor for a sliding door system.
