Honeywell CNI2 Operating And Installation Manual page 69

If you do not require pulse-counting on a line then configure it as a Form-A alarm input
so that all other pulse-counting inputs have access to as much storage space as
The data collection system (DC-2009
channels are activated. The minimum is 1 and the maximum is 4.
When the data collection system receives the pulse records from the CNI2 it expects them to be
in a specific order starting with the 1
restrictions regarding the order in which you program the pulse-counting lines. You could
program Line #1 and Line #2 as alarms and #9 and #10 as pulse-counters. To stay compliant
with DC-2009 here is how the records are sent:
The very 1st line that is programmed for pulse counting is considered "Input-1".
The next line that is programmed for pulse counting is considered "Input-2".
The next line that is programmed for pulse counting is considered "Input-3".
The next line that is programmed for pulse counting is considered "Input-4".
Remember that a Form-C pair is treated as only one input.
Here's an example:
Lines #1, 2, 9 and 10 are configured as alarm inputs and Lines #11 and #12 for pulse-counting.
Line #11 is presented as "Input-1" to DC-2009 because it's the 1st line programmed for pulse-
counting. Line #12 is presented as "Input-2" because it's the 2nd line programmed for pulse-
counting.
Here's another example involving a mixture of Form-C and Form-A settings:
Lines #1 and #2 are programmed for pulse-counting, Form-A operation. Lines #11 & #12 are
configured for Form-C pulse counting. Line #1 is presented as "Input-1" to DC-2009 because
it's the 1st line programmed for pulse-counting. Line #2 is presented as "Input-2" because it's
the 2nd line programmed for pulse-counting. Lines #11/#12 are presented as "Input-3" because
they are the 3rd set of lines programmed for pulse-counting.
