No, it will be strictly a DC current, with the amperage easily calculated from
the voltage difference between the two ends and the resistance of however many
cable-feet of wire is involved.  Not usually a big deal, unless your
termination design didn't include the ability to sink a DC current 24/7.

(Of course, actually measuring the voltage and resistance may be non-trivial :)
