Figure 4 Wiring the N-ANN-80C to an FACP
Notes for Figure 3 and Figure 4:
1.
All connections/sources must be power-limited and supervised.
2.
12 - 22 AWG (0.33 - 3.31 mm2) wire for N-ANN-80(-W) and 12-
18 AWG (0.75 - 3.25 mm2) for N-ANN-80C is acceptable for the
24 VDC circuit.
3.
Power wire distance limitation is set by 1.2 volt maximum line drop
from source to end of circuit.
4.
Maximum distance from FACP to last ANN-BUS device must not
exceed 6,000 feet (1,800 m). Refer to the Wiring Distance Table in
the appropriate FACP manual for wire gauge and distance
limitations.

Setting the DIP Switches - N-ANN-80(-W)
Address Setting
Each ANN-BUS device requires a unique address. DIP switches 1-4 on
S1 are used to set the address. This address will be displayed on the LCD
display as the Station ID number.
A maximum of 8 devices can be connected to the FACP ANN-BUS
communication circuit. ANN-BUS device addresses do not need to be
sequential and can be set to any number between 01 and 08. Note that 00
is not a valid address. The following illustrates the DIP switch settings
for each address (ID Number).

Communication Protocol
DIP switch 5 is used to determine the communication protocol of the N-
ANN-80 Series. Set DIP switch 5 to ON for ANN-BUS protocol. Set
DIP switch 5 to OFF for AIO protocol.

End-of-Line Resistor
The end-of-line termination resistor must be enabled at S1 on the last
device on the communication circuit. All other annunciators should have
these switches set to disable.
