Event Memory; Event Log; Ground Fault Detection; Ground Fault Detection Added Feature - Bosch D9412GV4 Installation And Operation Manual

3.3.10 Event Memory

The control panel retains point alarm and trouble
events in memory for each area. A D1255 (any
model) or a D1260 (any model) can be used to
view event memory by using COMMAND 40. The
control panel clears the previous events for an
area from the event memory when the area is
armed.

3.3.11 Event Log

The system stores 1023 events from all areas in
its event log. For example, the system adds at
least two items to the log each time an area is
armed or disarmed, the open (or close) event
that also contains the previous arming state.
All events can be stored even if the control panel
does not send a report for them. The log can be
viewed at a keypad, printed locally using the
D9131A Parallel Printer Interface Module and a
parallel printer, or uploaded using Remote
Programming Software (RPS).
For a list of the log events, refer to the appendix
in the user's guide for the keypad.

3.3.12 Ground Fault Detection

The Earth Ground Terminal on the control panels
is electrically isolated from all other terminals to
allow the control panels to detect ground fault
conditions. A Ground Fault Detect Enable switch
(S4) is located just under Terminal 10, Earth
Ground, on the control panel. Refer to Section
4.5.2 Ground Fault Detect Enable on page 17 for
information on operating this function.

3.3.13 Ground Fault Detection Added Feature

When Ground Fault Detect is enabled (S4
closed), Points 1 to 8 can be used for non-
powered fire-initiating devices such as heat
detectors, four-wire smoke detectors, and pull
stations. A D125B Powered Loop Interface or a
D129 Dual Class A Interface Module is not
required when connecting the non-powered fire-
initiating devices to Points 1 to 8.

3.3.14 Conettix Functions

The D6600 Conettix System supports data
network communications. Conettix allows the
D6600 Receiver to connect to various network
technologies including Ethernet and GPRS
(General Packet Radio System). Connecting to a
data network is possible using the COM4 or
COM1 connection from the D6600 Receiver to
the D6680 Network Adapter. Control panels can
send reports through telephone lines, Ethernet,
or GPRS networks to the D6600 receiver at the
central station. Once events are received, they
can then be issued to automation software or a
network printer through a local area network
(LAN) or wide area network (WAN).
Sending events to the central station over a LAN
or WAN requires a network interface module
(NIM), such as the DX4020. Sending events over
GPRS requires a special NIM, the ITS-DX4020-G.

3.3.15 Programming

Use the Remote Programming Software (RPS), or
the local Programmers Menu, to program the
control panels. Refer to the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U218312) for programming
options.

3.3.16 Dual Authentication

The D9412GV4 and D7412GV4 control panels can
be configured to require two forms of
identification before processing certain system
commands. This feature requires a door
controller and a keypad to be installed within
proximity to each other for user convenience.
Dual Authentication requires a door
controller module even though the
configured operation may not be
access.
A standard system user has authority to use Dual
Authentication if they have a passcode, a door
credential (token or card), and appropriate
command authority permissions assigned in the
door and keypads assigned area. When enabled
at a keypad, only the following Passcode
Functions require access credentials with
passcode entry, Arm / Disarm, Cycle Door (Grant
Access), Cycle Relay, and Auto Re-arm. Refer to
the D9412GV4/D7412GV4/D7212GV4 Program
