Federal Communications
Commission (FCC) Rules
Part 15
This equipment was tested and found to comply with
the limits for a Class A digital device, pursuant to Part
15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful
interference when the equipment is operated in a
commercial environment.
This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used
according to the instructions, can cause harmful
interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference, in which case the
user is required to correct the interference at his or
her own expense.
Part 68
This equipment complies with Part 68 of FCC rules. A
label contains, among other information, the FCC
registration number and ringer equivalence number
(REN). If requested, this information must be provided
to the telephone company.
The D7212GV3 Control Panel is registered for
connection to the public telephone network using an
RJ38X or RJ31X jack.
The REN is used to determine the number of devices
that can be connected to the telephone line.
Excessive RENs on the telephone line may result in
the devices not ringing in response to an incoming
call. In most, but not all areas, the sum of the RENs
should not exceed five. To be certain of the number of
devices that can be connected to the line, as
determined by the RENs, contact the telephone
company to determine the maximum REN for the
calling area.
If you experience trouble with the D7212GV3 Control
Panel, please contact Bosch Security Systems, Inc.
Customer Service for repair and warranty information.
If the trouble is causing harm to the telephone
network, the telephone company might request that
the equipment be removed from the network until the
problem is resolved. User repairs must not be made,
and doing so will void the user’s warranty.
If the D7212GV3 Control Panel causes harm to the
telephone network, the telephone company attempts
to notify you in advance. If advance notice is not
practical, the telephone company notifies you as soon
as possible. Also, you will be advised of your right to
file a complaint with the FCC if you believe it is
necessary.
The telephone company might make changes in its
facilities, equipment, operations, or procedures that
affect the operation of the equipment. If this happens,
the telephone company provides advance notice in
order for the necessary modifications to be made in
order to maintain uninterrupted service.
This equipment cannot be used on public coin service
provided by the telephone company. Connection to
Party Line service is subject to state tariffs. (Contact
your state public utilities commission for information.)

D7212GV3 |Operation and Installation Guide | 2.0 Lightning Strikes
.
Bosch Security Systems, Inc. | 10/10 | F01U143079-03 7
2.0 Lightning Strikes
The control panel is designed to significantly reduce
electromagnetic interference and malfunction
generally caused by lightning.
2.1 Effects
Any electronic system can be struck directly by
lightning or be adversely affected by a lightning strike
near the system. When lightning strikes, several
things happen:
•An electromagnetic wave spreads from the point
of the strike inducing high voltages in nearby
conductors.
•The voltage changes substantially on electrical
grounds near the lightning strike.
•High voltages are induced upon anything directly
struck by lightning.
Symptoms of installations that lightning might strike or
affect are Missing Trouble, Missing Alarm, or Point
Bus Trouble events. Occasionally, Reboot and
Watchdog events might be sent because the control
panel tried to reset itself.
Electronic systems, including control panels, cannot
be completely immune to direct or indirect lightning
strikes; however, some proven installation practices
might greatly reduce the risk of undesirable affects.
2.2 Precautions during Installation
To minimize the risk of undesirable effects from
lightning strikes on high risk installations that use a
point-bus technology:
•Do not run wiring outside the building.
•If you must install the unit in a metal building,
keep the wiring at least 2 ft away from external
metal surfaces.
•Earth ground the unit correctly. Do not use an
electrical ground or telephone ground.
•Avoid running wires near telephone, data, or
power lines inside a building. Historical evidence
shows that locating control panel wiring at least 2
ft away from telephone, data, or power lines is
successful at minimizing lightning damage. When
your data lines must cross the path of AC or other
wiring, cross the lines perpendicularly.

3.3 Features in the D7212GV3
3.3.1 SDI Molex Connector
Use the SDI Molex Connector to easily connect an
SDI device with the SDI bus. Possible applications
include:
•Connecting a DX4010i to program the control
panel with Remote Programming Software
(RPS) at the premises
•Connecting a keypad to test the control panel.
Do not connect the D5200 Programmer to
the SDI Molex connector.
Control panel firmware v8.11 or later
does not support the D5200.
UL requires that the DX4010i be used for
programming only.
3.3.2 Tip and Ring Posts
The tip and ring posts allow connecting a phone or
buttset for the purpose of troubleshooting
communications between the control panel and the
central station. This connection allows monitoring of
the dial tone, handshaking tones from the receiver,
and communications signals.
3.3.3 Telephone Line Sniff
The D7212GV3 Control Panel monitors the phone line
for the programmed supervision interval before
indicating a phone line trouble.
3.3.4 Points
The Bosch Security Systems, Inc. D7212GV3 Control
Panel provides up to 40 points of protection. Point
programming parameters determine the control
panel’s response to open and shorted conditions on
the sensor loop for the point. Several options allow
individual point programming to custom-fit the
protection to the installation.
Points 1 to 8 are located on the circuit board (on-
board points). They are standard sensor loops. The
remaining off-board points are POPIT points using
D8128D OctoPOPITs, D8125 POPEX Modules and
D9127 POPITs, or the ISW-D8125CW-V2
Commercial Wireless Interface Module. MUX devices
can also be used with the D8125MUX.
Any points programmed as fire
supervisory points are latching.
3.3.5 Areas and Accounts
The system supports up to four separate areas. You
can assign all points to a single area or distribute
them over as many as four areas.
The control panel is armed and disarmed by area,
and several areas can be armed and disarmed with
one menu function. A passcode can also be assigned
an authority level that allows a user to arm an area
from a remote keypad in another area. Assigning
each area its own account number creates four
separate accounts in one control panel. Assigning the
same account number to different areas groups them
together in a single account.
Area options include exit tone and delay, separate fire
and burglary outputs, and multiple opening and
closing windows. Area type can be used to create
area interdependencies for arming purposes.
3.3.6 Digital Communicator
The control panel uses a built-in digital communicator
to send reports to the receiver. The control panel
sends reports in either the Modem IIIa2ANSI-SIA
Contact ID format. All software versions for the D6600
can be used with the control panel.
The control panel connects to an RJ31X or RJ38X
jack for telephone line seizure. Connecting to the
RJ31X complies with FCC regulations for using the
public telephone network. The control panel can be
programmed to direct reports to four separate
telephone numbers.
The system can route groups of Event Reports to four
different destinations. Each report group can be
programmed to send reports to one or more
destinations. Primary and backup reporting paths can
be programmed for each destination and each report
group. A custom option allows specification of
individual Event Reports to be sent.
3.3.7 Keypads
Up to 32 unsupervised keypads can be connected to
the system. The available power, number of
supervised keypads, and number of areas covered
affect the total number of keypads that can be
connected.
The system can supervise up to eight keypads. The
control panel sends a Serial Device Trouble Report,
SDI FAILURE in the Modem IIIa2format or
Expansion Module Failure (333) in Contact ID format,
if it loses communication with a supervised keypad.
More than 8 keypads can be added, but the system
can only supervise up to 8 keypads. Table 4 on
page 12 shows the compatible keypads with the
D7212GV3 Control Panel. Refer to Keypad in the
D7212GV3 Program Entry Guide (P/N: F01U170808)
for complete details on programming keypad options.

3.3.8 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.
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
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.
3.3.13 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,
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.

4.5 Connecting Earth Ground
4.5.1 Terminal 10
To help prevent damage from electrostatic charges or
other transient electrical surges, connect the system
to earth ground at Terminal 10 before making other
connections. Recommended earth ground references
are a grounding rod or a cold water pipe.
Warning:
Do not use telephone or electrical ground
for the earth ground connection. Use
1.8 mm (14 AWG) to 1.5 mm (16 AWG)
wire when making the connection.
Do not connect other control panel
terminals to earth ground.
4.5.2 Ground Fault Detect Enable
A ground fault is a circuit impedance to earth ground.
The control panel has a ground fault detection circuit
that, when enabled, detects ground faults on
Terminals 1 to 9 and 11 to 32. The control panel also
detects and annunciates ground faults on any device
connected to it.
•If a ground fault condition occurs, the keypads
display SERVC GND FAULT and the control panel
sends a GROUND FAULT TROUBLE, AREA 1.
When the control panel recognizes that the
ground fault condition is corrected, and remains
corrected for between 5 to 45 consecutive sec, a
Restoral Report is sent.
The D7212GV3 Control Panel logs and
prints a Ground Fault event as a Trouble
Point 256 if communicating in Modem IIIa2
format. If communicating in Contact ID
format, the D7212GV3 generates a
Ground Fault (310) event.
4.5.3 Enabling Ground Fault Detection

board relay (Terminal 8) remains deactivated when
the reset pin is locked in the disable position.

D7212GV3 |Operation and Installation Guide | 4.0 Installation
16 Bosch Security Systems, Inc. | 10/10 | F01U143079-03
Releasing the reset pin from the closed position
resets the control panel. The control panel resets all
its timers, counters, indexes, and buffers. Any points
that restore after a reset do not generate Restoral
Reports.
If the reset pin is placed in the disable position when
all areas are armed, there must be an entry in the
Answer Armed program item. Refer to RPS
Parameters in the D7212GV3 Program Entry Guide
(P/N: F01U170808).
Locking the pin in the disable position applies power
to the control panel and charges the battery while the
detection devices and keypads are installed.

4.6.1 Charging the Battery
Connect the battery, then the transformer to allow the
control panel to charge the battery while you complete
the installation. Refer to Section 5.0 Power Supply on
page 20 for instructions.
On-board Buzzer Sounds at Power Up and Reset:
The system performs a series of self-diagnostic tests
of hardware, software, and programming at power up
and at reset. The buzzer on the control panel sounds
during the tests. The self-diagnostics tests complete
in approximately 1 to 3 sec.
If the control panel fails any test, the buzzer continues
sounding and a System Trouble message appears at
the keypads.
Touch Terminal 10 First: If the on-board buzzer
sounds briefly when the control panel is touched, any
static charge you carry discharges to the control
panel.
Avoid electrostatic discharge. Always touch
Terminal 10, the earth ground connection,
before beginning work on the control panel.
If the control panel receives an electrostatic
discharge, it might generate Watchdog Reset and
Param Fail events.
4.6.2 Installing and Wiring Detection Devices

Combined continuous current draw for Terminals 38,
24, and 32, and the accessory connector cannot
exceed 1.4 A. Refer to Section 6.0 Power Outputs on
page 24 for help.
4.7 Programming the Control Panel
If the control panel is not already programmed, review
the D7212GV3 Program Entry Guide
(P/N: F01U170808). Ensure that all accessory
modules for desired features are available for
installation.
Use RPS to load a custom program into the control
panel as needed.
4.8 Installing the Point Chart Label
The point chart label is required for fire
systems with verifications points.
A point chart label is included in the literature pack.
Install the point chart label for fire or combined fire-
and-burglary systems that use verification points.
Use the D7212GV3 Program Record Sheet
(P/N: F01U170810) to gather the necessary
information for completing the point chart. Fill out the
label and install it on the inside of the enclosure door
(refer to Figure 2 on page 14).
Avoid smearing the entries on the chart.
Use the peel-off backing to press the label
in place.
4.9 Testing the System
After installing and programming the control panel,
test the system completely. Test the control panel and
all devices for proper operation.
Test after initially programming the control
panel and after subsequent programming
changes.
Refer to Section 4.10 Service Walk Test for complete
Service Walk Test instructions.
Clear after Test: To clear the event memory and
report buffer, momentarily close the reset pin. Events
stored in the control panel’s event log are not cleared.
4.10 Service Walk Test
The Service Walk Test differs from the standard Walk
Test. In the standard Walk Test, POPITs whose
switches are set for a point number not programmed
in the control panel do not appear in the test. In the
Service Walk Test, POPITs whose switches are set
for a point number that is not programmed in the
control panel do appear in the test.
The Service Walk Test allows the installer to walk test
all points from a control-panel-wide keypad,
regardless of the point index type.
A Service Walk Test can also be initiated by account-
wide or area-wide keypads but test only those points
that are within the scope of the keypad that initiated
the function. The Service Walk Test does not test
points in armed areas.
Only Walk Test Start and Walk Test End
are reported to the central station.
The D9131A can be configured for local
printing. Refer to the D7212GV3 Program
Entry Guide (P/N: F01U170808).
During a Service Walk Test, the summary
alarm and summary fire remain off, because
there are no Fire or Burg alarm conditions
to summarize. The P# Relay Response
Type feature operates as programmed.

D7212GV3 |Operation and Installation Guide | 5.0 Power Supply
20 Bosch Security Systems, Inc. | 10/10 | F01U143079-03
5.0 Power Supply
5.1 Primary Power Terminals 1 and 2
5.1.1 Primary (AC) Power Circuit
The primary source is a 16.5 VAC, 40 VA, internally-
fused transformer (Bosch Security Systems, Inc.
Model D1640). The control panel draws 200 mA when
idle and 500 mA when in an alarm state. The total
available auxiliary current is 1.4 A.
Transient suppressors and spark gaps protect the
circuit from power surges. This protection relies on
the ground connection at Terminal 10. Ensure that
you connect Terminal 10 to a proper ground. Refer to
Section 4.5 Connecting Earth Ground on page 15.
AC Power Fail
The system indicates an AC power failure when
Terminals 1 and 2 do not have power. The AC Fail
Time parameter sets the number of minutes or
seconds without AC power before the control panel
acknowledges the failure and the number of minutes
or seconds after the power returns before the control
panel acknowledges restored power. Refer to the
D7212GV3 Program Entry Guide (P/N: F01U170808)
for additional information about AC Fail Time.
5.1.2 Installing the Transformer
Do not short-circuit the terminals of the
transformer: Shorting the terminals opens
the internal fuse, causing permanent failure.
Connect the transformer to Terminals 1 and
2 of the control panel before plugging it into
the power source.
1. Use 1.22 mm (18 AWG) wire (minimum) to
connect the transformer to the control panel.
The wire length should be as short as possible.
The maximum length is 15 m (50 ft). Connect the
battery and plug in the transformer.
2. Route telephone and sensor loop wiring away
from any AC conductors, including the
transformer wire.
AC wiring can induce noise and low level voltage
into adjacent wiring. Route data wiring away from
AC and telephone wiring.
Always connect the battery first and then
plug in the transformer.
3. Connect the battery. Refer to Section 5.2.2
Installing the Battery on page 21.
4. Plug the transformer into an unswitched, 120
VAC, 60 Hz power outlet only.
5. Secure the transformer to the outlet with the
screw provided.
D8004 Transformer Enclosure Required for Fire
Systems: Use the D8004 Transformer Enclosure for
the D1640 Transformer in fire and combined
fire/burglary applications.
Check with the Authority Having
Jurisdiction (AHJ) about mounting
transformers on specific circuits.
5.2 Secondary Power Terminals
5.2.1 Secondary (DC) Power
A 12 V, 7 Ah (up to 14 Ah) sealed lead-acid
rechargeable battery supplies secondary power for
auxiliary and alarm outputs, and powers the system
during interruptions in primary (AC) power.
Warning - Use Lead Acid Batteries Only:
The charging circuit is calibrated for lead-
acid batteries. Do not use gel-cell or nicad
batteries.
Extra Batteries Increase Back-up Time
To increase battery back-up time, connect a second
12 V battery of equal capacity in parallel to the first
battery. Use a D122 Dual Battery Harness to ensure
proper and safe connection. Refer to the Standby
Battery and Curent Rating Chart in the D7212GV3
Approved Applications Compliance Guide
(P/N: F01U143080).
D1218 Battery
The D1218 is a 12 V, 17.2 or 18 Ah battery for use in
applications requiring extended battery standby time.
Up to two D1218 batteries can be connected when
used with a D122 Dual Battery Harness.
Caution: When connecting two D1218
Batteries to the control panel, both must have
the same capacity (use two 17.2 Ah batteries
or two 18 Ah batteries).
When using two D1218 batteries, use a
separate enclosure, a D122L Dual Battery
Harness, and long leads.
