GND and 100V are used to connect 100V speakers
Use Class II wiring:

5. AC Power
The CXA160 and CXA80 are fitted with a detachable IEC
socket for AC input.
Each unit is fitted with a universal power supply, allowing
it to operate from any AC mains supply from 100 to 240
VAC, 50-60 Hz.
A 6-foot U-Ground to IEC power cable is supplied.
An integrated, removable, AC input fuse is fitted just below
the IEC socket. To remove or inspect the fuse, first unplug
the power cord from the AC socket. Then use a small
screwdriver to gently pry open the rectangular fuse holder
and inspect or replace the fuse. Replacement fuses must
be of the same rating as the original fuse.
Low voltage fuses are located internally.
6. DC Power
These terminals allow the amplifier to be powered using
24 VDC emergency power supplies.
4 VDC
The unit will automatically switch to external DC battery
power if your local AC power fails. You will need to
connect an external 24 Volt battery to the DC battery
terminals.
Make absolutely sure the positive post of your battery
connects to the positive terminal, and the negative
post connects to the negative terminal. To minimize the
voltage drop across the wires and prevent overheating, use
at least 14 AWG insulated wire.

The unit seamlessly switches to the backup supply if
there's a power loss, allowing safety instructions and
emergency communications to continue. When both AC
power and 24 VDC power are connected, the AC power is
used and no current is drawn from the DC supply.
Note: The unit will not charge the battery, so you should
have a dedicated charging system. Note also, that when
running on DC power, the output is lower than when
running on AC power.
