The figure below illustrates an example circuit for determining maximum wire length where values are provided for
minimum operating-voltage of the NAC channel output (Vopmin), maximum current of the circuit (Imax),
wire-resistance-per-foot of the circuit (Rwire) and maximum current-draw of the strobe (Istrobe):
