B208 Octo-input modules cannot support some
point assignments, for example points 9 and 10,
19 and 20, 29 and 30, etc. These inaccessible
point assignments can be supported on the
ZONEX bus or SDI2 Wireless RF points. On the
GV4 Series Control Panels, each off-board point
assignment can be assigned a Point Source to
define its bus type.
13.3.2 Supervision
Supervision of B208 Octo-input Modules on the
SDI2 bus is enabled automatically when the Point
Source of a point assignment is set to Octo-input.
Each Octo-input module supports a fixed range of
point assignments. Refer to Table 29 on page 83
for point 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.
13.4 B308 Octo-output Module
The B308 Octo-output module is an 8 relay
expansion device that connects to control panels
through the SDI2 bus. This module is supervised
and communicates to the control panel to
provide 8 independently controlled outputs. Each
output can operate as either normally open or
normally closed.
Review the information in Section 6.0 Power
Outputs on page 30 to ensure that there is
enough power for the B308 and other powered
devices you want connected to the system.
On the D9412GV4 control panel, you can add up
to 12 Octo-output modules. On the D7412GV4
control panel, you can add up to 6 Octo-output
modules. On the D7212GV4 control panel, you
can add up to 2 Octo-output modules.
13.4.1 Address Settings
The control panel reads rotary switch
setting changes on power up. If you
change the switches after installation
and applying power to the control
panel, you must recycle the power to
the control panel.
The B308 rotary switches provide a tens and a
ones setting for the module’s address. For single-
digit address numbers 0 through 9, set the tens
switch to 0 and the ones digit to the appropriate
number. Refer to Figure 29 on page 70. Only
address 01 through 32 are valid for the B308
module.

Valid B308 addresses are dependent on the
number of relays allowed by a particular control
panel.
B308 Octo-output modules cannot support some
relay outputs, for example relays 9 and 10, 19
and 20, 29 and 30, etc. These inaccessible
outputs can be supported on the ZONEX bus. On
the control panels, each off-board relay can be
assigned to a destination to define its bus type
(SDI2 or ZONEX).
