DTMF Off Code

When the Cv2 receives the DTMF Off code, it sets the output port to the Off state. After the Off code has been received and the output port cleared, the Cv2 announces the current status of the output.

This code can be 1 to 7 digits in length and may use any of the 16 DTMF digits including A, B, C, and D.

Default DTMF Off Code: an empty string - no Off Code.

Timed Output Point

In addition to the common settings, there are two DTMF control codes used with an Timed output point.

DTMF On Code

When the Cv2 receives the DTMF On code, it sets the output port to the On state and the timer begins operation. After the On code has been received and the output port set, the Cv2 announces the current status of the output. If the timer is set for a short interval, the output port may have returned to the Off state before the announcement is made.

This code can be 1 to 7 digits in length and may use any of the 16 DTMF digits including A, B, C, and D.

Default DTMF On Code: an empty string - no On Code.

DTMF Off Code

When the Cv2 receives the DTMF Off code it sets the output port to the Off state and terminates the timer operation if it is currently running. The DTMF Off code will have no effect if the output timer has already expired. After the Off code has been received and the output port cleared, the Cv2 announces the current status of the output.

This code can be 1 to 7 digits in length and may use any of the 16 DTMF digits.

Default DTMF Off Code: an empty string - no Off Code.

3.5.3 Group section

In some applications, there may be a requirement for different types of alarms to alert different people. This is handled in the Cv2 by assigning alarms to different groups; there are six groups available for this purpose. Each alarm point has a selection list for setting the Using Group parameter. In the group dialog, the directory that it will be using is selected in the Shift control section. If the group activities are not going to be altered by changing shifts, use the shift 1 selection for all groups. If the use of directories by a group is going to change through the Shift Control, enter the appropriate directory into the shift selections.

Each Group has its own Acknowledge Code, Interrogate Code and Timer settings. Activities for a particular group are performed according to the Shift that is selected. Each shift uses one of the directories as the instruction source for the sequence of actions that occur during alarm
