Operations Overview 1-4

For example, to call four telephone numbers, the directory would appear as:
1. [DIAL]2458829 [VOICE]
2. [DIAL]2336700 [VOICE]
3. [DIAL]9842121 [VOICE]
4. [DIAL]9843316 [VOICE]
If you want an alert tone to precede the voice message the directory line would look like this:
1. [DIAL]2458829 [ALERT] [VOICE]
The next example shows a sequence that is used to call a numeric paging terminal. After the
call is placed there is a four second delay for the paging terminal to respond before the Cv2
sends the number to be displayed on the pager. When calling a paging terminal, it is
sometimes useful to allow the called party time to call the Cv2 back and acknowledge the
alarm before the Cv2 advances to the next line in the directory. This can be done by using the
Wait command on its own line; the entry below will cause a four minute delay before the next
line is executed.
1. [DIAL]2458829 [WAIT]4 [DTMF]4567
2. [WAIT]240
Directory lines can be added, removed, or modified and new lines can be inserted between
existing lines.
1.5 How do you want to respond to an alarm call?
After the Cv2 has finished speaking the alarm messages, it prompts the called party with the
phrase “Enter Acknowledge Code” and then waits five seconds for the code to be returned. If
the code is received, it will terminate any further callout activities until a new alarm occurs;
otherwise, it will proceed to the next line in the directory. There is a Temporary
Acknowledge Time that can be set in the General section that will override the operation of
the Acknowledge Code. If the temporary time is set to a value other than Off, and the
received Acknowledge Code has the digit # appended to it, the Cv2 will remain in the
acknowledged state only for this time interval. After the timer has expired and if the alarm
condition still exists, the Cv2 will resume alarm reporting. This feature is used as a safety
measure to ensure that an alarm cannot be acknowledged and then left unattended.
Each group has its own Acknowledge Code which only affects points that have been assigned
to the group. Other groups with different Acknowledge Codes will continue alarm reporting
if they do not receive their own code.
Using the Auto Ack command in a directory will cause the Cv2 to automatically acknowledge
any alarms that are in the group using the directory. This feature must also be enabled for that
group, since other groups of points may be using the same directory. Auto Ack must be on
the last line in a directory since any further commands will never be executed.
Another method of acknowledging the Cv2 is by activating the special function that allows
hardware inputs to be used as local acknowledge controls.
