12.0 SDI Devices

12.1 Description

The D9412GV4/D7412GV4 V2.03Control 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 65), D9210C Access Control
Interface Module, DX4010V2 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 Approved Applications
chapter found in this guide 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 (refer to Table 23
below).
These devices can share power with the
control panel or be powered by a stand-alone
power source.

12.2.1 Open Wire Trouble on SDI

The D9412GV4/D7412GV4 V2.03Control Panels
can detect an open wire fault in the data
communication lines of the SDI bus. Any open
wire on Terminals 30 or 31 results in a system
fault trouble display on all keypads, and a
general SDI Fault event sent to the central
station.
12.3 D9210C Access Control
Interface Module
The Bosch Security Systems, Inc. D9210C
Access Control Interface Module is a four-wire
powered device providing connections for an
access door point and door strike. The
D9412GV4 can supervise eight Wiegand
Control Modules, the D7412GV4 can supervise
two. Each D9210C supports one door to
control access. Programming allows each
access door to be configured independently.

12.3.1 Access

Using Wiegand style cards or tokens, the
D9210C can allow access for up to 999 cards
or tokens on the D9412GV4, and up to 399 on
the D7412GV4. User access authority can be
configured to restrict access to certain doors
or to certain periods of time. The reading of
access cards, in addition to granting access,
can control whether the system disarms.

12.3.2 Switch Settings

Rotary switches on the D9210C assign a
unique address to each module. Table 25
shows the correct switch setting for each
D9210C address.
