D9412GV2/D7412GV2 Operation and Installation Guide 6.0 Power Outputs
6.0Power Outputs
6.1Circuit Protection
Three Positive Temperature Coefficients (PTCs) 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 IIIa2 Communication Format, or TROUBLE ZN 9 for BFSK. One PTC protects :
•Terminal 3: Auxiliary Power
•Terminal 24: Zonex Power.
A
Another PTC protects:
•Terminal 6: Alarm Power Output
•Terminal 7: Alternate Alarm Power Output
•Terminal 8: Switched Auxiliary Power.
A
The third PTC protects Terminal 32: Power +.
6.2Total Available Power
The system produces up to 1.4 A of combined power at
10.2VDC to 13.9 VDC for all powered devices. 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: Normally open, power on alarm.
Terminal 7 (Relay B) - Alternate Alarm Power Output: Normally open, power on alarm.
Terminal 8 (Relay C) - Switched Auxiliary Power: 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.
Terminal 32 - 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.
6.3Continuous 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 over a range of 10.2 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 on page 25).
6.4Programmable Power Output Terminals 6, 7, and 8
6.4.1Programming
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 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
6.4.2Terminals 6 and 7, 6.4.3 Fire System Power Formula, and 6.4.4 Terminal 8 on page 26 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.
