1.5.2 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
seconds, a Restoral Report is sent.
1.5.3 Enabling Ground Fault Detection
To enable the Ground Fault Detect Enable feature, lock (close) the S4 Ground Fault Detect
Pin on the control panel (refer to Figure 1.2, Page 6).
Figure 1.2 Ground Fault Detect (S4)
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.
NOTICE!
To meet UL 864 requirements, enable Ground Fault Detect.
NOTICE!
The D9412GV3/D7412GV3/D7212GV3 Control Panels log and print a Ground Fault event as a
Trouble Point 256 if communicating in Modem IIIa2format. If communicating in Contact ID

1.5.4 GV3 Series Ground Fault Specifications
Table 1.1, Page 7 provides the impedance specifications for detecting ground faults when any
terminal or field wiring is shorted to ground.
Table 1.1 Ground Fault Impedance Specifications
1.5.5 Locking the Reset Pin
Locking the reset pin disables the control panel (refer to Figure 1.3, Page 7). 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 D9412GV3/
D7412GV3 Program Entry Guide (P/N: F01U170807) or 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.
When the Reset Switch (labeled S1) is closed, the communication module at SDI Address 92
is disabled. While in this mode, remote programming communication is only supported by the
communication module at SDI Address 88.

3 Power Supply and Power Outputs
3.1 Power Supply - Primary
3.1.1 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 300 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 1.5 Connecting Earth Ground, page 5.
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 D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) or the
D7212GV3 Program Entry Guide (P/N: F01U170808) for additional information about AC Fail
Time and UL 864 requirements.
3.1.2 Installing the Transformer
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.
3. Connect the battery. Refer to Section 3.2.2 Installing the Battery, page 17.
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
and burglary applications.
NOTICE!
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.
NOTICE!
Always connect the battery first and then plug in the transformer.
NOTICE!
Check with the Authority Having Jurisdiction (AHJ) about mounting transformers on specific
circuits.

D1218 Battery
The D1218 is a 12 V, 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.
3.2.2 Installing the Battery
1. Place the battery upright in the base of the enclosure.
2. Locate the red and black leads supplied in the literature pack.
3. Connect the black battery lead to Terminal 4, and then to the negative (-) side of the
battery.
4. Connect the red battery lead to Terminal 5, and then to the positive (+) side of the
battery.
WARNING!
Use Lead Acid Batteries Only: The charging circuit is calibrated for lead-acid batteries. Do not
use gel-cell or nicad batteries.
WARNING!
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).
NOTICE!
When using two D1218 batteries, use a separate enclosure, a D122L Dual Battery Harness,
and long leads.
WARNING!
High current arcs are possible. The positive (red) battery lead and Terminal 5 can create high
current arcs if shorted to other terminals or the enclosure. Use caution when working with the
positive lead and Terminal 5. Always disconnect the positive (red) lead from the battery
before removing it from Terminal 5.
WARNING!
The battery terminals and wire are not power limited. A 6.4 mm (0.250 in.) space must be
maintained between the battery terminals, battery wiring, and all other wiring. Battery wiring
cannot share the same conduit, conduit fittings, or conduit knock-outs with other wiring.

example) when they are assigned to an area. Relays can be assigned to one or more areas.
The Bosch defaults set Relay A (Terminal 6) as a Steady Alarm Bell output, Relay B (Terminal
7) as a Pulsed Fire Bell output, and Relay C (Terminal 8) as a Verification or Reset output for
smoke detectors. The D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) and the
D7212GV3 Program Entry Guide (P/N: F01U170808) contain complete instructions for
programming relays. Refer to Section 3.6.2 Terminals 6 and 7, page 20, Section 3.6.3 Fire
System Power Formula, page 21, and Section 3.6.4 Terminal 8, page 21 for descriptions of the
functions of each terminal. Refer to the Bell Parameters section of the program to set the Fire
Bell, Alarm Bell output responses for relays. Four annunciation patterns are available: Steady,
Pulsed, California Standard, and Temporal Code 3.
Voltage Output at Terminals 6, 7, and 8
If Terminals 6, 7, and 8 do not provide the expected output, check:
– Programming for Relays A, B, and C in the relays section of the program.
– Bell Parameters section of the program to confirm that the Alarm and Fire Bell responses
are programmed for the expected duration and pattern.
– Point Assignments section to confirm that each point is programmed for the expected
local response.
3.6.2 Terminals 6 and 7
When activated, Terminals 6 (Relay A) and 7 (Relay B), provide positive (+) 12.0 VDC Nominal
power output. Use the power at Terminals 6 and 7 to power bells, siren drivers, piezoelectric
fire sounders, electronic horns, or other devices.
Programming determines the format of the output and the conditions that activate it. One
self-resetting circuit breaker protects Terminals 6, 7, and 8 against shorts. When using Relay A
or Relay B to activate notification appliance circuits in UL Listed fire alarm applications, install
a D192G Indicating Circuit Module.
