    How to Wire the Remote NAC to the Option Bus

    Issue

    How does the FPP-RNAC-8A-4C, D7038, and DS9484 wire to the Option Bus on the D7024/DS9400 fire panels?

    Solution

    Wiring for the FPP-RNAC-8A-4C, D7038, and DS9484 to the D7024/DS9400 fire panels.

    The Option Buss Terminals of the FPP-RNAC-8A-4C, D7038, and DS9484 are labeled as follows:

    TX = Yellow

    RX = Green

    RTN = Black +

    12V = Red

    The Option Bus Terminals of the D7024/DS9400 Series fire panels are labeled as follows: 

    YA = Yellow

    GA = Green

    BA = Black

    RA = Red

    The D7024/DS9400 as two Options Busses the Second bus is labeled:

    YB = Yellow

    GB = Green

    BB = Black

    RB = Red

    Black & Red of both busses (RA/BA or RB/BB) will provide 12VDC but only one of the two busses Green & Yellow (GA/YA or GB/YB) will provide the Option Bus Data Out to operate the bus devices.
