A sticker on the front of the B450 indicates proper switch positions for selecting various SDI or Option Bus addresses (see figure 1).

There are 2 types of FPD-7024 panels. It must first be determined which is in use before selecting the B450 address:
Newer types with firmware version 1.06 and higher. These types are identified by icons on the keypad instead of words (see figure 2).
Older types with firmware version 1.03 and lower. These types are identified by words on the keypad.

Version 1.06 & newer types:
When used as sole communicator or backup to phone line, set the address wheel at 9 for Option Bus address 250.
When used as backup to a primary network communicator, set the address wheel at 6 for Option Bus address 134.
RPS connections require Option Bus address 250. Be sure the address wheel is set at 9 on the network communicator intended for RPS connections (Ethernet is preferred when allowed).
Version 1.03 and older types:
Use Option Bus address 250. Only one network communicator is available on these panel types.
