Interrogate Code
The Interrogate Code is a 1 to 7 digit DTMF string that is used to make the Cv2 announce
the condition of points in the group. Each group can have a unique Interrogate Code, or
different groups can use the same code in order to generate the status of all groups at once.
Default Interrogate Code: an empty text string.
Enable This Group
To allow this group to be used for alarm reporting, this setting must be enabled. Points that
are used for ‘interrogate only’ have this setting turned off. Groups may also be enabled or
disabled via the local (or remote) programming phone.
Default Group Enable: disabled
Enable Auto Ack
If the Auto Ack function is used as a Directory command, it must enabled here for it to be
valid for this group.
Default Auto Ack: disabled
Enable Ack Request
At the completion of an alarm announcement sequence, the Cv2 will query the called party
with the phrase “Enter Acknowledge Code’. If this prompt is not required, clear the enable
setting.
Default Ack Request: enabled
Timers
The Cv2 uses a two-stage timer to schedule the interval between reporting sequences. The
first stage is controlled by the Short Timer interval which will repeat for the number of
times set in Short Cycles before moving to the Long Timer. Once the Cv2 has reached the
Long Timer stage it will continue to use this timer until a new alarm occurs.
Short Timer
The Short Timer can be set to any value between 0 and 255 minutes.
Default Short Timer: 5 min.
Short Cycles
The maximum number of short cycles is 9.
Default Short Cycles: 4
Long Timer
The Long Timer can be set to any value between 0 and 255 minutes.
Default Long Timer: 30 min.
Shift Selection
There are four shifts that can be used to alter the way that the Cv2 reports alarms. The
group will use the currently active shift to select a directory for its operations. The shift in
use at any particular time is determined by the last time that a Shift Change Code message
was received. The Cv2 retains the current shift when it is powered down and will return to
that shift when power is restored. Each time a Shift Change Code is received, the shift
advances by one; if the Cv2 is currently set to shift 4 and the Shift Change Code is
received, it will go to the shift 1 setting. After receipt of the Shift Change Code, the Cv2
responds with a spoken message indicating the new shift setting. The Shift Change Code is
set in the General section.
