* Connect with at least 1.5 m (5 ft.) of 0.8 mm (22 AWG) wire
(4.3 m [14 ft.] of 1.2 mm [18 AWG] wire).
Switching the Green and Yellow Wires Affects
Other Keypads: Connecting the green wire
incorrectly from the keypad to Terminal 31 and the
yellow wire to Terminal 30 causes other keypads
connected to the control panel to go blank or to sound
random beep tones.
You can connect devices to the data bus (Terminals
30 and 31) by parallel wire run from the control panel
to each device, wire from device to device, or a
combination of the two using a maximum of 4572 m
(15000 ft) of 0.8 mm (22 AWG) wire for all devices
connected to the SDI Bus combined.
Wire Limits for Individual Devices
Refer to the installation instructions for each device
for wire length specifications.

Extra Power for More Keypads
The D1255 and D1255B Keypads draw 104 mA when
idle. They draw 206 mA with the keys lit and the
sounder activated. Review Section 6.0 Power Outputs
on page 26 to determine the total power output
requirements for the system.
One or more D8132 Battery Charger/Power Supply
Modules can be added for the number of keypads
used. Figure 28 on page 57 shows the D8132
powering keypads in a stand-alone configuration.
For UL Certificated accounts, use a UL Listed
auxiliary 12.0 VDC or 24 VDC regulated, power-
limited power supply for Fire Protective Signaling
Units and Commercial or Residential Burglar Units.
The D8132 is not UL Listed as a stand-alone power

If using the ground fault detection
capability on the D9412GV3 and
D7412GV3 Control Panels with an
external power supply, ensure that the
external selected power supply isolates
its earth ground connection from the
negative side of the auxiliary power
output. External power supplies that do
not isolate earth ground can cause
ground fault conditions on the control
panel.
