Appendix A

HART 7 Communications

Highway Addressable Remote Transducer (HART®) establishes digital data communication

over 4-20mA Current Loop cables. The HART protocol uses FSK modulation signals

superimpose at a low level on top of the 4-20mA current.

The HART implementation on the F-Guard IR3/UV-IR Flame Detector allows the Control Unit to

monitor the status of the detector, settings of User Configuration and initiate field diagnostics.

The HART protocol implemented in this flame detector corresponds to HART rev. 7.0.

It supports HART Universal commands including Common Practice and Device Specific

Commands.
