Cords
A modular cord is needed for connecting the headset adapter to the associated
voice terminal. The cord carries audio signals between the adapter and the
terminal and power for the adapter.

The headset adapter is mounted close to its associated voice terminal.
Color Options
The 500A headset adapter is silver while the 502A is black.
Power
The 500A Headset Adapter requires either AC or DC auxiliary power from one of
the sources listed in the Adjunct Power section earlier in this manual. Power,
from the source supply, is applied by way of the voice terminal’s mounting cord
and the adapter’s connecting cord. The 502A draws its power from the system
switch through the associated voice terminal.
