The B8512G and B9512G have slots for two B430 Plug-in Telephone Communicators to provide redundant telephone connections.
Upon power up the panel uses the B430 in the Mod-1 slot until a Test Report is initiated or when the panel phone supervision declares the line currently in use as failed.

This article explains the proper address selection when connecting the B450 to a Bosch Intrusion Panel.
This information is needed to determine which address to select based on panel type, panel firmware revision and if Remote Programming Software will use the B450 to connect to the panel.
Note the sticker on the front of the B450 which indicates switch positions for selecting an SDI2, SDI or Option Bus address (see figure 1).

B8512G, B9512G and B-Series types:
The B450 is not required when the cellular communicator will be installed in the Mod-1 (lower) plug-in slot.
Use the B450 in applications where signal strength is weak at the panel location. Install the B450 in a remote location with stronger signal strength and connect to SDI2. Follow the instructions below for GV4 panel types connecting to SDI2.
GV4 Panel Types:
Only 1 network communicator is allowed on a single address. Use address 1 or 2 as needed to avoid conflicting with another network communicator on the same address.
Connections with Remote Programming Software are available on either address 1 or 2.
GV4 or GV3 using SDI:
Only 1 network communicator is allowed on a single address. Use address 88 or 92 as needed to avoid conflicting with another network communicator on the same address.
When used as sole communicator or as back-up communicator to Phone line, use address 4 for SDI address 88.
When used as back-up communicator to Ethernet (B426) use address 5 for SDI address 92, unless the B450 will be used for RPS connections (see note 4 below).
Note that SDI address 88 is required for connecting to Remote Programming Software (Ethernet is preferred when allowed).
GV2 v7.06+ Panel Types (SDI only):
Use address 4 for SDI address 88.
