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 D7212GV2 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 D712GV2 Control
Panel, please contact Bosch Security Systems 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 D7212GV2 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.)

D7212GV2 |Operation and Installation Guide | 2.0 Lightning Strikes
.
Bosch Security Systems, Inc. | 5/05 | F01U003805B 7
2.0 Lightning Strikes
The control panel is designed to significantly reduces
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.

Bosch Security Systems, Inc. | 5/05 | F01U003805B 11
3.3 Features in the D7212GV2
3.3.1 SDI Molex Connector
Use the SDI Molex Connector to connect easily an
SDI device with the SDI bus, without needing to
disconnect wires connected to the SDI terminals.
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.
For a D1260ATM keypad, set the address
of the DIP switch to 7. The default for
Address 7 has the Area Scope and
Enhanced CMD Ctr parameters set to Yes.
Do not connect the D5200 Programmer to
the SDI Molex connector.
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. With this connection, the dial tone,
ACK tone handshake, and ACK and NACK signals
can be monitored.
3.3.3 Super Capacitor
The D7212GV2 has a capacitor called Super Cap. This
component preserves the parameters stored in the
control panel’s RAM chip when the lithium battery is
replaced. The Super Cap can retain voltage for up to
30 minutes after the lithium battery is removed.
Plan to replace the lithium battery after 3 to 5 years of
continual service.
When replacing the lithium battery, ensure
that you disconnect the primary AC power
and secondary battery power from the
control panel before you remove the old
battery. Then install the new battery and
connect the primary AC and secondary
battery power to the control panel.
3.3.4 Telephone Line Sniff
The D7212GV2 monitors the phone line for the
programmed supervision interval before indicating a
phone line trouble. Phone line trouble occurs when the
phone line voltage drops to 6 V or below, without a
corresponding 8 mA to 13 mA increase in current.
3.3.5 Points
The Bosch Security Systems D7212GV2 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 or
D8127 POPITs. MUX devices can also be used with
D8125MUX or wireless transmitters with the
D8125INV.
3.3.6 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.
3.3.7 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 IIIa2or BFSK format. The
MPU and line cards for the D6500 receiver must have
software revision 8.00 (or greater) installed to accept
Modem IIIa2reports from the control panel. Refer to
the D6500 or D6600 literature to determine the MPU
software version.
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.

D7212GV2 |Operation and Installation Guide | 3.0 Overview
12 Bosch Security Systems, Inc. | 5/05 | F01U003805B
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.
3.3.8 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
TROUBLE ZN D in the BFSK format, if it loses
communication with a supervised keypad.
More than eight keypads can be added, but supervision
of only eight is possible. Table 4 shows the compatible
keypads with the D7212GV2 Control Panel. Refer to
Keypad in the D7212GV2 Program Entry Guide
(P/N: F01U003804) for complete details on
programming keypad options.

3.3.9 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.
3.3.10 Event Memory
The system uses event memory to store events for each
area. A D1255 Keypad or D1260 Keypad assigned to
an area allows viewing of the events for the area. The
control panel clears the events for an area from event
memory and starts storing new events when the area is
master armed.
3.3.11 Event Log
The system stores 500 to 1000 events and event
modifiers from all areas in its event log. Event
modifiers add information about an event to the log.
Some events are always followed by a modifier. 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 and an event modifier showing the
previous arming state.
All events and their modifiers 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 and event modifiers, 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 D7212GV2 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.
3.3.13 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 Programming
Use the Bosch Security Systems D5200 Programmer or
the Remote Programming Software (RPS) to program

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.
•To enable ground fault detection, the Ground Fault
Detect Enable jumper (S4) (Figure 3) must be
locked (closed) and a non-zero value must be
entered in the Area 5 Silent Alarm Relay. When
jumper S4 is in the unlocked (open) position, the
control panel does not detect ground fault
conditions.
•If a ground fault condition occurs, the keypads
display SERVC GND FAULT and the control panel
sends a GROUND FAULT TROUBLE, AREA 1
(Modem IIIa2format only).
When the control panel recognizes that the ground
fault condition is corrected, and remains corrected
for between 5 to 45 consecutive seconds, a Restoral
Report is sent.
The D7212GV2 Control Panel logs and
prints a Ground Fault event as a Trouble
Point 256 if communicating in Modem IIIa2
format. If communicating in BFSK format,
the D7212GV2 generates an Alarm Zone 5
event.

4.5.5 Locking the Reset Pin
Locking the reset pin disables the control panel
(Figure 4). When the control panel is disabled, the
system ignores the keypads and points. CALL FOR
SERVICE appears in keypad displays when the pin is
locked down.
On-board relays (Terminals 6 and 7) and off-board
relays deactivate when the control panel is reset.
Terminal 8 has power when the relay is deactivated.
Activation interrupts power at that terminal. The on-
board relay (Terminal 8) remains deactivated when the
reset pin is locked in the disable position.
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 D7212GV2 Program Entry Guide
(P/N: F01U003804).
Locking the pin in the disable position applies power to
the control panel and charges the battery while the

Bosch Security Systems, Inc. | 5/05 | F01U003805B 19
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 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 Failure
The system indicates an AC power failure when
Terminals 1 and 2 do not have power. The AC Fail
Time program item 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
D7212GV2 Program Entry Guide (P/N: F01U003804) for
additional information about AC Fail Time.
5.1.2 Installing the Transformer
Do not short 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 19.
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

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 (D126) 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, 7 Ah
battery in parallel to the first battery to form a 12 V, 14
Ah battery. Use a D122 Dual Battery Harness to ensure
proper and safe connection.
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).
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.
5.2.2 Installing the Battery
