12.0 SDI Devices
12.1 Description
D9412GV2 and D7412GV2 Control Panels can
support a number of accessory devices from the SDI
Bus using Terminals 29 through 32. Some devices
include the D1255 and D1255B Keypads (refer to
Section 11.0 Arming Devices
on page 58), D9131A
Parallel Printer Interface Module, D9210B Wiegand
Control Interface Module, DX4010i RS-232 Serial
Interface Module, D9133 Serial Interface Module, and
DX4020 Network Interface Module.
For UL 864 Commercial Fire applications,
refer to
Installing Combination Fire and
Intrusion Alarm Systems
in the
D9412GV2/D7412GV2 Approved
Applications Compliance Guide
(P/N: F01U003639) for important
information about combination fire and
intrusion systems.
12.2 Installation
For complete installation instructions, consult the
operation and installation guide for the specific SDI
device. SDI devices connect to the control panel in
parallel (
Table 22
).
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
SDI 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.
12.3 D9131A Parallel Printer Interface
Module
The Bosch Security Systems, Inc. D9131A Parallel
Printer Interface Module is a four-wire powered device
used to connect a standard parallel printer to a control
panel. D9412GV2 can supervise three printers and
the D7412GV2 can supervise one printer. A separate
D9131A Parallel Printer Interface Module is
necessary for each printer. The D9131A connects to
the printer using a standard parallel printer cable.
Do not
connect the D9131A to systems
that require commercial fire listings. The
electrical ground on the D9131A does not
isolate earth ground.
12.3.1 Switch
Settings
Switches on the D9131A assign a unique address (17
to 19) for each printer. The address determines if the
printer is supervised, the area scope of the printers,
and the area to which the printer is assigned. Refer to
Printer Parameters
in the
D9412GV2/D7412GV2
Program Entry Guide
(P/N: F01U003636) for a
complete description of addresses.
Table 23
shows the correct switch setting for each
address.

12.3.2 Supervision
Supervision includes:
•
Proper operation of the SDI bus
•
Proper connection of the printer cable between
the printer and the D9131A
•
Printer paper supply
•
Printer selected (on-line)
•
Printer power.
The control panel sends an SDI Failure Report to the
receiver if communication with the printer interface
fails. If an SDI failure occurs, SERVC PRINTER
appears at the keypad. The report to the receiver
includes the address of the troubled D9131A to
indicate which printer needs service.
