Fault Recovery/Diagnostics
2.4.1
Power Failure Transfer
Description
If the power supply to the PBX fails, outside (CO) line 1 will be automatically connected to extension jack 01
(
Power Failure Connections
). The PBX will switch from the current connections to Power Failure
Connections, and all existing conversations will be disconnected.
Only outside (CO) line calls handled by Power Failure Connections can be made during a power failure.
Conditions
•
We recommend connecting an SLT in parallel at extension jack 01, so that the SLT can be used during
a power failure.
Note that if the parallelled SLT is on an outside (CO) line call when the power is restored, that call will
be disconnected.
•
Only outside (CO) line calls are possible during a power failure. All other features will not function.
•
Automobile-type batteries, which must be user-supplied, can be connected as a system backup power
supply to operate all the features during a power failure.
The batteries can be connected directly to the unit with optional cables. For more information, refer to
the Installation Manual.
