Operation ACC2500 Audio Control Center
09/08 12
Idle Mode
When power is applied, the ACC2500 is in the receive or idle mode, allowing any AMI audio to be heard
through the speaker or handset. It is always in this mode unless the unit is transmitting.
The ACC2500 contains an internal or local speaker and a handset that operate as follows:
• When the handset is in the cradle, or on-hook, audio is heard on the internal speaker. In some
operational modes, this can be changed, i.e., muting the speaker by pressing CTL + VOL Down.
• When the handset is off-hook, audio is routed to the handset receiver. By using the front panel buttons,
you may optionally select to hear audio through the local speaker in addition to the handset.
Zone Selection
The system can have many zones available to the operator each including one to many speakers or
broadcast assemblies. In order to select the proper zone for a broadcast of any type, the operator must first
select the desired zone. This zone is displayed on the first line of the LCD display.
Note that during installation and programming, the zone label can be changed to a desired display using the
CARD Suite application. By default, if nothing is programmed, the word “Zone” will be displayed on the
first line of the display. This could be changed to “Group,” “Area,” “Z” or any alphanumeric description
of up to eight characters.
After initial power-up, the display will be as shown below where the address of all units and zones is
programmed to be 3 digits in length.
→ Z o n e : _ _ _
The “ → ” in the first location of the first line indicates that the zone selection is active. To manually select a
zone using the numeric key, enter the desired address or zone. To select zone 123, press “1,” “2,” followed
by “3.” As the digits are entered, the first digit will be display in the third blank and moved to the left as
subsequent digits are entered. If more than the allowed number of digits is entered, the zone entry will be
cleared and the last digit will become the first digit of the new address. After entry of the zone, the display
will appear as shown below:
→ Z o n e : 1 2 3
