2.9 Auxiliary Connection for Power Failure Transfer
2.9.1 Auxiliary Connection for Power Failure Transfer
Power Failure Transfer connects specific Single Line Telephones to selected trunks in the event
of system power failure.
Please refer to "Power Failure Transfer " in Section "1.4 Fault Recovery/Diagnostics" of the
Features Guide for further information.
The Auxiliary Connection (Please refer to the illustration below) is required to implement this
feature.
Notes
• The KX-TD500 System switches the current connection to the Auxiliary Connection
automatically when the power supply dies.
• While DC power is provided by the backup batteries when the AC power fails, the KX-
TD500 System does not switch the current connection to the Auxiliary Connection.
