ACC2500 Audio Control Center Operation
13 09/08
If zone aliases have been programmed using the CARD Suite application, the operator may choose a zone
using a name instead of a direct number. For example, zone 123 can be programmed as “Zone 1,” zone
234 can be “Zone 2,” zone 345 can be “Zone 3,” zone 456 can be “Zone 4” and all zones can be “Zone
All.” To select a particular zone, the operator can use the
ZONE Up/Down buttons to scroll to the desired
zone such as “Zone 3” as shown below:
→ Z o n e : Z o n e 3
If the alias has a pre-configured alarm associated with it, the alarm will be displayed on the second line of
the display. The operator may not override or turn off this pre-configured alarm and attempting to do so
will display an error message along with an error tone.
If the operator wishes to revert to manual entry, pressing the STOP/CLR button will switch back to manual
entry and will display the last manually entered zone. If the unit is programmed to restrict manual entry of
the zone addressed, pressing the
STOP/CLR button will result is an error message and tone. While in
manual entry mode, pressing STOP/CLR a second time clears the zone entry.
Initiating Live Voice Broadcasts without an Alarm
After selecting the desired zone, the operator may initiate a live broadcast immediately by pressing and
holding any PTT source such as the main
TRANSMIT button, handset PTT or PTT of a connected
accessory.
Upon pressing and holding PTT, if the selected zone is not active (more on this below) the unit will
generate the necessary DTMF digits to activate the desired zone. During the DTMF generation, the second
line of the display will be:
Z o n e : Z o n e 3
* * * WA I T * * *
After generation of the DTMF sequence, the AMI, if programmed to do so, will generate a
preannouncement tone that is broadcast over the unit speaker and the selected zone. The operator will hear
the preannouncement tone and will be instructed to wait during the generation of the tone. Upon
completion of the preannouncement tone, the display will change to:
A C T I V E : Z o n e 3
* * * T A L K N OW * * *
“ACTIVE” will be flashing indicating that the selected zone has been activated and is within its time-out
duration. As long as the PTT source is held, the display will remain in this state. The operator may speak
whenever the display indicates ***TALK NOW***.
To cease voice broadcast the operator must release the PTT source. Upon doing so, the display will change
to:
A C T I V E : Z o n e 3
