POWER FAILURE OPTIONS

To Provide Battery Backup

Your Inter-Tel 3000 can be equipped with an optional Battery Backup Unit (BBU). When equipped, full
operation of the Inter-Tel 3000 is provided for at least one hour in the event of a power failure.

Battery Alarm

If your system is equipped with a battery, a message "Battery" is displayed on extension 20 if the system is
running on the battery. If you are not aware that the normal power has failed, check that the Inter-Tel 3000
System is correctly plugged in.

To Make Outgoing Calls Following a Power Failure

•
In the event of a power failure (with the system not equipped with a BBU), analog CO lines are
switched automatically to standard analog telephones and calls can be made and received on these lines
until the power is restored.
•
The system installer will indicate the location of these phones.
•
A minimum of half the equipped CO lines are connected to phones.

LIGHT-EMITTING DIODE (LED) INDICATORS

A status LED on the BBU is provided.
•
GREEN indicates the unit is running from the main AC power source and the battery is charging or
fully charged.
•
ORANGE indicates the unit is running off the battery.
•
RED indicates that the battery is discharged.
•
Flashing RED indicates the battery is disconnected and the system is running from the main AC power
source.
