2.19 Auxiliary Connection for Power Failure Transfer
Power failure transfer connects a specific single line telephone (SLT) to selected outside
(CO) lines in the event of system power failure, as follows.
Outside (CO) line 1 – extension (T, R) jack 01
Outside (CO) line 4 – extension (T, R) jack 09
Connection of outside (CO) lines 1 and 4, and the respective extensions require no
auxiliary connection.
• In the event of a power failure, system memory is protected by a factory-provided
lithium battery. There is no memory loss except the Camp-on, Saved Number Redial,
Last Number Redial, Call Park and Message Waiting memories.
• The system automatically changes the current connection to the above connection
when the power supply stops.
• Proprietary telephones cannot be used during a power failure. Therefore, we
recommend connecting SLTs in parallel with proprietary telephones connected to
extension jacks 01 and 09, or connecting a KX-T7033 (power failure telephone).
• If DC power is available from backup batteries when AC power fails, the system will
not change the current connection to the above connection. (☞ 2.17, Backup Batteries
Connection)
