Notes:
1. Up to 5 XSIG cards allowed per source NAC.
2. XSIG cards must be in same location as the source NACs.
3. Last XSIG card in chain requires EOLR Jumpers P3 & P4 to
be installed in the IN position (2-3); otherwise, jumpers are installed in OUT position.
4. The source NAC is dedicated to providing a signal to the XSIG card and is wired in a Class B configuration.
5. Minimum wire gauge is 18 AWG (0.8231 mm2).
6. Remove the 10 k, 1/2W EOL resistors from the amplifiers and XSIG Cards that accept the Constant Supervision NAC modules.
