6.1

Circuit Protection

Three self-resetting circuit breakers protect the control
panel from short circuits on the continuous and
programmable power outputs. If the control panel is
programmed for power supervision and a short circuit
occurs on one of the power outputs, the control panel
sends a BATTERY LOW or BATTERY MISSING for
Bosch Security Systems Modem IIIa
Format, or TROUBLE ZN 9 for BFSK.
One self-resetting circuit breaker protects :
•
Terminal 3: Auxiliary Power
•
Terminal 24: Zonex Power.
A short circuit on one terminal disrupts
power to the other terminal.
Another self-resetting circuit breaker protects:
•
Terminal 6: Alarm Power Output
•
Terminal 7: Alternate Alarm Power Output
•
Terminal 8: Switched Auxiliary Power.
A short circuit on one of the terminals
disrupts power to the other two terminals.
The third self-resetting circuit breaker protects
Terminal 32: Power +.
6.2

Total Available Power

The system produces up to 1.4 A of combined power
at 12 VDC nominal for special application use. The
outputs listed below share the available power. These
outputs are shown as red circles on the faceplate.
Terminal 3 - Auxiliary Power: Use this terminal to
power devices requiring continuous power.
Terminal 6 (Relay A) - Alarm Power Output:
Programmable relay normally open, power on alarm.
Terminal 7 (Relay B) - Alternate Alarm Power
Output: Programmable relay normally open, power
on alarm.
Terminal 8 (Relay C) - Switched Auxiliary Power:
Programmable relay normally closed, switches power
off when the Sensor Reset command is executed.
Terminal 24 - Zonex Power: Use this terminal to
power Zonex modules such as the D8125, D8128D,
and D8129 Modules.
28
Terminal 32 – SDI Power +: Use this terminal to
power serial device interface (SDI) devices such as
keypads, the D9131A Parallel Printer Interface
Module, and the D9210B Wiegand Control Interface
Module.
Accessory Connector: The D928 Dual Phone Line
Switcher connects to the accessory connector.
6.3

The continuous current draw for powered devices
Communication
connected to Terminals 3, 8, 24, and 32, and the
accessory connector must not exceed 1.4 A. Devices
powered from these outputs operate over a range of
10.0 VDC to 13.9 VDC.
Power Restricted for Fire and Combined Fire and
Burglary Systems: Use the Fire System Power
Formula to calculate the current available for fire and
combined fire and burglary systems (refer to Section
6.4 Programmable Power Output Terminals 6, 7, and
8).
6.4
6.4.1
The power outputs at Terminals 6, 7, and 8 are
programmed as Relays A, B, and C. All relays are
programmed in the Relays section.
Relays are assigned a relay type, (Fire Bell, for
example) when they are assigned to an area. Relays
can be assigned to one or more areas.
The Bosch Security Systems, Inc. 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 D9412GV2/D7412GV2
Program Entry Guide (P/N: F01U003636) contains
complete instructions for programming relays. Refer
to Sections 6.4.2 Terminals 6 and 7, 6.4.3 Fire
System Power Formula, and 6.4.4 Terminal 8 on
page 29 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.
