2.5.2
Connecting Earth Ground
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 14 AWG (1.8
mm) to 16 AWG (1.5 mm) wire when making the connection. Do not connect other control
panel terminals to earth ground.
Ground Fault Detect Enable
Notice!
To meet UL 864 requirements, enable Ground Fault Detect.
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 36.
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.
2.5.3
Enabling Ground Fault Detection
To enable the Ground Fault Detect Enable feature, lock (close) the S4 Ground Fault Detect Pin
on the control panel.

Ground Fault Impedance Specifications
The table below provides the impedance specifications for detecting ground faults when any
terminal or field wiring is shorted to ground.
Impedance Control Panel Detects Ground Fault
≤ 300 Ω Yes
300 Ω to 200 k Ω Detection depends upon the terminal
≥ 200 k Ω No
Table 2.1: Ground Fault Impedance Specifications
Locking the Reset Pin
Locking the reset pin disables the control panel. When the reset pin is locked, the control
panel is disabled. CALL FOR SERVICE appears in some keypad displays (SDI2 keypads display
enter Installer Passcode) when the pin is locked down.
On-board outputs (Terminals 6 and 7) and off-board outputs deactivate when the control
panel is disabled. Terminal 8 has power when the output is deactivated. Activation interrupts
power at that terminal. The on-board output (Terminal 8) remains deactivated when the reset
pin is locked in the disable position.
Unlocking the reset pin from the locked 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 Lock position, and all areas are armed, the control panel will
not answer RPS over a phone line unless the Answer Armed program item has a value other
than zero in it. No entry is required for network or RPS Enhanced direct connection
communication. Refer to RPS Parameters in RPS Help.

Power Supply and Power Outputs
Power Supply - Primary
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 225 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 Connecting
Earth Ground, page 8.
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 D9412GV4/D7412GV4 v2.02 Program Entry Guide (P/N: F01U265459) for

Programming
The power outputs at Terminals 6, 7, and 8 are programmed as Outputs A, B, and C. All
outputs are programmed in the Outputs section. Outputs are assigned a output type, (Fire
Bell, for example) when they are assigned to an area. Outputs can be assigned to one or more
areas. The Bosch defaults set Output A (Terminal 6) as a Steady Alarm Bell output, Output B
(Terminal 7) as a Pulsed Fire Bell output, and Output C (Terminal 8) as a Verification or Reset
output for smoke detectors. The D9412GV4/D7412GV4 v2.02 Program Entry Guide (P/N:
Control Panel Power Supply and Power Outputs | en 27
F01U265459) contains complete instructions for programming outputs. Refer to Terminals 6
and 7, page 27, Fire System Power Formula, page 27, and Terminal 8, page 28 for
descriptions of the functions of each terminal. Refer to the Bell Parameters section of the
program to set the Fire Bell, Alarm Bell, and Gas Bell output responses for outputs. Four
annunciation patterns are available: Steady, Pulsed, California Standard, Temporal Code 3,
and Temporal Code 4.
Voltage Output at Terminals 6, 7, and 8
If Terminals 6, 7, and 8 do not provide the expected output, check:
– Programming for Outputs A, B, and C in the outputs section of the program. For proper
operation, do not program a Panel Wide Output the same as an Area Wide Output.
– Bell Parameters section of the program to confirm that the Alarm, Fire, and Gas 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.
4.6.2
4.6.3
Terminals 6 and 7
When activated, Terminals 6 (Output A) and 7 (Output 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 selfresetting circuit breaker protects Terminals 6, 7, and 8 against shorts. When using Output A or
Output B to activate notification appliance circuits in UL Listed fire alarm applications, install
a D192G Indicating Circuit Module.
Available Power
The system combines the 1.4 A of primary power produced by the power supply with the
secondary power source (the battery) to produce a total of 2.0 A of alarm power at 12.0 VDC
Nominal. Terminals 6 and 7 share the available alarm power.
Power Restricted for Fire and Combined Fire and Burglary Systems
Fire systems are prohibited from using the battery for determining alarm power. Use the fire
system power formula described in Fire System Power Formula, page 27 to calculate the
current available for fire and combined fire and burglary systems.
Fire System Power Formula
To calculate the current available at Terminals 6 and 7 for fire and combined fire and burglary
systems:
1. Add together the current draws for all devices connected to Terminals 3, 8, 24, and 32,
and the accessory connector. This is the total current required for the normal standby
condition (NSC).
2. The current available for NSC is 1.4 A. Subtract the NSC current required calculated in
Step 1 from the NSC current available, 1.4 A. The difference is the alarm current available
for Terminals 6 and 7.
In formula format:
1.4 A - NSC current required (Step 1) = Alarm current available
Refer to the Approved Applications chapter inside the D9412GV4/D7412GV4 v2.02 Installation
and System Reference Guide (P/N: F01U265457) for module or accessory current requirements.

28 en | Power Supply and Power Outputs Control Panel
4.6.4
Terminal 8
Terminal 8 provides continuous positive (+) 12.0 VDC Nominal power. Output C interrupts the
power at Terminal 8 when activated. Use Terminal 8 to power smoke detectors or other
devices that are reset by interrupting power. One self-resetting circuit breaker protects
Terminals 6, 7, and 8 against shorts.
Verification/Reset Output
The default program sets Output C (Terminal 8) as a verification and reset output. Refer to
Output Parameters and Point Assignments in the D9412GV4/D7412GV4 v2.02 Program Entry
Guide (P/N: F01U265459) for instructions on programming verification/reset outputs and
points.
Performing a sensor reset at a keypad produces a five-sec activation of reset outputs. The
control panel ignores verification and reset points during the five-sec activation.
