6.0Power Outputs

6.1Circuit 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 BATTERY LOW and BATTERY MISSING when using Bosch Security Systems, Inc. Modem IIIa2 communicator format. Under the same conditions when using Contact ID communicator format, the control panel sends Control Panel Battery Low (302) and Control Panel Battery Missing (311).

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 +.

UL requires any device powered from a power output to be supervised.

UL requires that power outputs are not shared between fire and non-fire devices unless all devices are in conduit within 20 ft and are in the same room.

6.2Total Available Power

The system produces up to 1.4 A of combined power at 12.0 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.

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.

6.3Continuous 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 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

6.4Programmable Power Output Terminals 6, 7, and

8).
