NAC Circuit Wiring
The MR-401 supports up to 4 NAC circuits that can be wired as either:
•
Class B
•
Class A
To supervise each Class B NAC circuit, use a 3.9K End-of-Line resistor.
Each NAC circuit provides up to 1.5A, total 6A of current maximum if no auxiliary power is
used.
For detailed wiring diagrams see Figure 17 NAC Circuit – Class B Wiring or Figure 18 NAC
