Keyswitch

Maintained or momentary closure devices such as
keyswitches allow any of the four available areas to
be armed or disarmed. Point programming
determines the loop responses and which area a
keyswitch controls.
3.3.9

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.

3.3.10 Event Log

The system stores 800 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.

3.3.11 Ground Fault Detection

The Earth Ground Terminal on the control panels is
electrically isolated from all other terminals to allow
the D7212GV3 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 15 for information on operating this
function.

Overview

3.3.12 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
Application
smoke detectors, and pull stations. A D125B Powered
Fire/Burglary/Access
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.

3.3.13 Conettix Functions

Fire
The D6600 Conettix System supports data network
communications. Conettix allows the D6600 Receiver
Fire/Burglary
to connect to various network technologies including
Ethernet and GPRS (General Packet Radio System).
Fire/Burglary
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,
Token-Ring 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.

3.3.14 Programming

Use the Remote Programming Software (RPS) to
program the D7212GV3 Control Panel.
Refer to the D7212GV3 Program Entry Guide
(P/N: F01U170808) for programming options.
