(SeeFigure 2-77 on page 2-58 for the first method.) The NAC is supervised andpower-limited. When an MPS-400 NAC supplies power to CMX modules:• The CMX module outputs are coded if the MPS-400 NAC is coded.• Program the MPS-400 NAC for general alarm. (Refer to the Programming Manualfor instructions.)1RWH 5HIHU WR WKH 'HYLFH&RPSDWLELOLW\ 'RFXPHQW IRUFRPSDWLEOH QRWLILFDWLRQDSSOLDQFHVConnect the NAC as follows:1. Connect the SLC to CMX terminals 1 (–) and 2 (+).2. Connect 24 VDC power from an MPS-400 NAC (TB7-TB10) to CMX terminals 3and 4.3. Terminate the power feed to the CMX module with a 2.2K ELR (PN R-2.2K) ormake the power feed a return to MPS-400 NAC terminals 3 and 4 (Figure 2-78).4. Set the CMX rotary switches to the required SLC address. (The CMX takes onemodule address on the SLC.)
