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.
You can connect a maximum of 15,000 feet of 22
AWG wire
for all Command Centers, printer
modules, and D9210s combined to the data
bus, terminals 30 and 31. You can connect
parallel wire runs from the panel to each device,
run wire device to device, or combine the two.
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 the
Power Outputs section to determine the total
power output requirements for your system.
You may need to add one or more D8132 Battery
Charger/Power Supply Modules for the number
of Command Centers you want to use. 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.

Figure 17: Power at Command Centers
Control/Communicator and D8132 (or other
power supply) must share COMMON: Note that
Figure 19 shows the common from the D8132
module connected to both the Command
Centers' common and the common on the
Control/Communicator.
A stand-alone power supply powering any device
connected to the panel must also be connected
to a common terminal on the panel. Do not
connect the stand-alone power supply to earth
ground other than terminal 10 on the panel.
D268/D269 Independent Zone Control
D279 Independent Zone Control
You can program any
on-board or OctoPOPIT
point so that the D268/D269 or D279
Independent Zone Control operates as
independent point control (arms and disarms the
point).
See the
Point Assignments in the D9000/D7000
Series Program Entry Guide (74-07695-000) for
programming information. See the
D268/D269
Operation and Installation Instructions
(74-05439-000) or the
D279 Operation and
Installation Instructions (74-05442-000) for wiring
and operation instructions.
