FNC-2000 Fire Network Controller Module
The FNC-2000 Fire Network Controller modules are wired from terminals marked Line A, positive and negative (see
specific cable recommended in Figure 37) to the Line B terminals of the next FNC-2000 module. Use of shielded
cable is not recommended. Wire from Line B terminals to Line A of the next FNC-2000 module. Start from the
lobby panel and wire to all the FNC-2000, wiring the last FNC-2000 back to Line B of the first FNC-2000 at the lobby
panel for Class A.
