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.
