13.0 SDI2 Devices
13.1 Description
GV4 Series Control Panels can support a number
of accessory devices from the SDI2 Bus using
Terminals 33 through 36. Some devices include
the B208 Octo-input Module, the B308 Octo-
output Module, and the B820 SDI2 Inovonics
Interface Module.
For UL 864 Commercial Fire
applications, refer to Installing
Combination Fire and Intrusion Alarm
Systems in the
D9412GV4/D7412GV4/D7212GV4
Approved Applications Compliance
Guide (P/N: F01U201525) for
important information about
combination fire and intrusion
systems.
13.2 Installation
For complete installation instructions, consult the
operation and installation guide for the specific
SDI2 device. SDI2 devices connect to the control
panel in parallel (Table 24).
These devices can share power with the control
panel or be powered by a stand-alone power
source.

A stand-alone power supply powering
the SDI2 device must also be
connected to a common terminal on
the control panel.
Do not connect the earth ground for
the stand-alone power supply to
Terminal 10 on the control panel.
13.2.1 Open Wire Trouble on SDI2
The GV4 Series Control Panels can detect an
open wire fault in the data communication lines
of the SDI2 bus. Any open wire on Terminals 34
or 35 result in a system fault trouble display on

13.3 B208 Octo-input Module
The Octo-input module is an 8 point expansion
device that connects to the control panel through
the SDI2 bus. This module is supervised and
communicates back to the control panel all point
status changes. The module's expansion points
work the same as the points on the control panel.
Review the information in Section 6.0 Power
Outputs on page 30 to ensure that there is
enough power for the B208 and other powered
devices you want connected to the system.
On the D9412GV4 control panel, you can add up
to 24 Octo-input modules. On the D7412GV4
control panel, you can add up to 7 Octo-input
modules. On the D7212GV4, you can add up to 3
Octo-input modules.
The B208 Octo-input Modules connect to the
SDI2 bus on the control panel using Terminals 33
through 36, or using the SDI2 interconnect wiring
connector. You can connect more than one
module to the control panel by wiring them in
parallel. Refer to the B208 Installation and
Operation Guide (P/N: F01U215232) for wiring
instructions.
13.3.1 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 cycle the power to
the control panel.
The B208 rotary switches provide a tens and a
ones setting for the module's address. For single-
digit address numbers 0-9, set the tens switch to
0 and the ones digit to the appropriate number.
Refer to Figure 28 on page 69.

Valid B208 addresses are dependent on the
number of points allowed by a particular control
panel. Refer to Table 29 on page 83.
