DS7200V2-EXP | Installation Guide | 2. System Installation
and Setup
See Power Outputs on page 8 to determine the
total power available for your system. You might
need to add one or more external power supplies
for the number of keypads you want to use. See
Figure 9 to connect an external power supply to a
keypad.
Do not tie the black (-) output to
earth ground when using an external
power supply. A ground fault
condition is reported if black (-) is
grounded.
You can use either one of the Aux Power (-)
terminals when connecting to the control panel.
Figure 9 shows the common from the external
power supply connected to both the keypad's
common terminal and the control panel's Aux
Power (-) terminal.

2.2.4 Keyswitch Overview
You can connect a maintained or momentary
contact arming device to arm or disarm any of the
areas in the system. The keyswitch is connected
to an on-board or off-board zone's sensor loop.
The control panel offers a wide variety of
keyswitch arming options. The default keyswitch
configuration is tamper-wired. See "Controlled
Keyswitch Types" in "Zone Function
Configuration" in the DS7200V2 Expert
Programming Guide (P/N: 4998153891) for
alternative keyswitch configurations.
Outputs can be programmed to activate LEDs,
sound alarm outputs, or activate strobes to
indicate arming status for keyswitch arming
stations. See Output Parameters on page 86 for
more information.
