2 ANN-80 Series Installation Document — P/N 52749:D1 8/17/10
Wiring the ANN-80 Series to the FACP
Refer to Table 1 and Figure 3 for wiring connections.
Notes:
1. All connections/sources are to be power-limited and
supervised.
2. 12 - 18 AWG (0.75 - 3.25 mm2) wire for 24 VDC
circuit is acceptable.
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
Wiring Distance Table in appropriate FACP manual
for wire gauge and distance limitations.
Setting the DIP Switches
Each ANN-BUS device requires a unique address.
ANN-80 Series DIP switch S21 is 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):
