12.0 SDI Devices 
12.1 Description 
D9412GV3 and D7412GV3 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 55), D9131A 
Parallel Printer Interface Module, D9210B Wiegand 
Control Interface Module, DX4010i RS-232 Serial 
Interface Module, ITS-DX4020-G GPRS/GSM 
Communicator, and DX4020 Network Interface 
Module. 
 
For UL 864 Commercial Fire applications, 
refer to Installing Combination Fire and 
Intrusion Alarm Systems
 in the 
D9412GV3/D7412GV3 Approved 
Applications Compliance Guide
  
(P/N: F01U143069) 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 21). 
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

common terminal on the control panel.  
Do not connect the earth ground for the

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. D9412GV3 can supervise three printers and 
the D7412GV3 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.  
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 D9412GV3/D7412GV3 
Program Entry Guide
 (P/N: F01U170807) for a 
complete description of addresses.  
Table 22 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. 
If an SDI device is supervised and Terminal SDI A 
becomes disconnected, the device can continue to 
operate normally, depending upon environmental 
conditions.
