To install the ZNDC with a Classic 2000 Mk II FACP, connect a cable between the RS485+ and
RS485- terminals on the ZNDC to the RS485+ and RS485- terminals on the panel (terminals 17
and 18). Power the ZNDC from a 24VDC source, either the network power connections on the
panel, a NAC configured as a power supply on the panel, or an IPB-3 power booster. Once the
ZNDC is connected, power up the panel, then scan the network. The ZNDC should appear at
address 10. If it does not, then check your connections and verify that the ZNDC is configured for
Classic 2000 Mk II operation.
