13.4.2 Supervision
Supervision of B308 Octo-output Modules on
the SDI2 bus is enabled automatically when
the Relay Destination of an off-board relay is
set to Octo-output. Each Octo-output module
supports a fixed range of off-board relays.
Refer to Table 24 for relay to module
assignments. Any failure to receive an expected
response from an SDI2 module results in a
system fault display on all keypads and a
module specific SDI FAULT event sent to the
central station.
13.5 B450 Plug-in Communicator
Interface
The B450 Conettix Plug-in Communicator
Interface is a four-wire powered SDI2, or SDI
device that provides two-way communication
over commercial cellular networks using a
plug-in communicator. The B450 bus address
switch determines the bus address of the
device. When required, configuration of the
module is managed through the control panel,
a local USB connection, or using SMS.
13.5.1 Address Settings
The B450 address switches provide a single-
digit setting for the module’s address. The
control panel uses the address for
communications.
Figure 31: B450 Switch Set to Address 1
The B450 has specific rotary switch settings
for SDI addresses 88 and 92 or SDI2 addresses
1 and 2 when used to communicate with
Remote Programming Software (RPS) or with a
central station network receiver. Refer to Table
27 for correct switch settings.
