4.2.1 View Zone Status
As shown in Fig. (2), the title of each zone is shown on topside of each zone (users can edit the titles), in terms of
zone status, blue color indicates that the terminal is currently online while gray color indicates that such terminal
is currently offline. A user can touch a target zone to select it and when a zone is selected, red color is shown
inside the border of such zone.
There are two lines of prompt messages under the zone title. The first line indicates playing information. It shows
program name when background music is played; "paging now..." is indicated when paging signal is received;
"Incoming call" is indicated when there is an incoming phone call; the chime name is shown when a chime is
inserted; warning message is shown when an alarm is played; "Warning Card Alarm" is indicated in case of an
alarm.
The second line shows status and volume level of a timing point. Status of timing point is indicated by "Run" or
"Stop". "Run" means that the zone is under timing control, while "Stop" means that such zone is under manual
control.
In the network public address system, a zone may include more than one terminal and a terminal may be defined
in more than one zones. For instance, "Grade One" is included in both "Full zone of primary school" and "All
broadcast zones". In addition, fire control zone and background music zone may be defined separately.
Tips
After manual operation on a zone is finished, it is important to switch it back to programmed status,
otherwise, the timing point will not be executed.
