11.2.1 Assigning an Address for the Keypad
Switches on the keypad assign an address (1 to 8).
The address determines if the keypad is supervised,
the scope of the keypad, and to what area the keypad
is assigned. Refer to Keypad Assignment in the
D7212GV3 Program Entry Guide (P/N: F01U170808)
for a complete description of addresses.
Table 17 shows the correct switch setting for each
address.
The D7212GV3 supports Keypad SDI
Addresses 1 to 8.

* 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 Keypad draws 104 mA when idle. It draws
206 mA with the keys lit and the sounder activated.
Review Section 6.0 Power Outputs on page 24 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 20 shows the D8132 powering keypads
in a stand-alone configuration.
For UL Certificated accounts, use a UL Listed
auxiliary 12.0 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 supply.
