3.5 Power Outputs - Continuous Power Output Terminals 3, 8, 24,
and 32
The continuous current draw for powered devices connected to Terminals 3, 8, 24, and 32,
and the accessory connector must not exceed 1.4 A. Devices powered from these outputs
must operate at 12.0 VDC Nominal.
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 3.6 Power Outputs - Programmable Power Output
Terminals 6, 7, and 8, page 20).

and 8

Programming

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 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

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.
F.01U.167.105 | 02 | 2010.11
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.
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.
