Features & Benefits

• Self-tuning and complete environmental tracking
• Complete low power CMOS digital design
• Three selectable modes: pulse, presence (normal ), presence (long)
• Digital delay and extension timers (detect output only)
• Three loop frequencies permit complete elimination of crosstalk
• The Winky-Blink™ loop monitor remembers and indicates intermittent and failed loops
• No manual reset required if intermittent or failed loops self-heal
• Thumbwheel switch for sensitivity settings
• Ten levels of sensitivity
• Red high intensity LED ID indicator illuminates whenever a vehicle is over the loop and transmitting valid data
• Gold contact toggle switches increase long term reliability

The 613D and 613D-SS vehicle detector/ receivers provide inductively coupled communication, LoopComm™, through a standard roadway loop from a vehicle transmitter (Model 600A). The ruggedly built
600A transmitter is uniquely designed to attach to the underside of a vehicle and connect to the vehicle electrical system. Coded radio frequency messages are
transmitted from the 600A and received by the Model 613D for vehicle identification and/ or control purposes. The 613D and 613D-SS are capable of functioning simultaneously as both normal inductive loop vehicle
detectors and receivers for vehicle detection.

Automatic Vehicle Identification (AVI) applications include VIP vehicle access, emergency vehicle access, door and gate activation, traffic signal preemption, bus priority systems, highway sign activation, and maintenance vehicle location systems.
