*Connect with at least 5 ft. (1.5 m) of 22 AWG wire (14 ft. [4.3 m] of 18 AWG wire).

Table 13: Command Center Connections

Switching the green and yellow wires affects other command centers: Incorrectly connecting the green wire from the command center to Terminal 31 and the yellow wire to Terminal 30 causes other command centers connected to the panel to go blank and/or sound random beep tones.

Devices can be connected to the data bus, Terminals 30 and 31, by parallel wire runs from the panel to each device, wire from device to device, or a combination of the two as long as a maximum of 15000 ft. (4572 m) of 22 AWG wire for all devices connected to the SDI Bus combined is used.

It is recommended, however, that command centers be limited to 2000 ft. (610 m) per run and the D9131A be limited to 1000 ft. (305 m) per run.

Extra power needed for more command centers: The D1255 Command Center draws 104 mA when it is idle. It draws 206 mA with the keys lit and the sounder activated. Review Section 5.0 Power Outputs on page 29 to determine the total power output requirements for the system.

One or more D8132 Battery Charger/Power Supply Modules may need to be added for the number of command centers that will be used. Figure 17 shows the D8132 powering command centers in a stand-alone configuration.

For UL certificated accounts, use a UL Listed power supply. The D8132 is not UL Listed as a stand-alone power supply.

Application

Tip

CAUTION

Control/Communicator and D8132 (or other power supply) must share COMMON:

Note that Figure 17 shows the common from the D8132 Module connected to both the command centers' common and the common on the control/communicator. Any stand-alone power supply powering any device connected to the panel must also be connected to a common terminal on the panel.

If you are using the Ground Fault Detect capability on the D7212G Control/Communicator and an external power supply:

Make sure that the external power supply selected isolates its Earth Ground connection from the negative side of the Aux Power output. External power supplies that do not isolate Earth Ground will cause ground fault conditions on the control/communicator.
