Configuration Of An Alarm Input - Honeywell CNI2 Operating And Installation Manual

CNI2 Operating and Installation Guide
Any description can be changed in the data collection system. For instance if Line#10 is used
for something other than the TAMPER switch it will still be reported to the data collection system
as a TAMPER alarm. But you can change the alarm description at the central office to
something like "Pump Failure" or "High Temperature" to more-accurately describe the event.
NOTE
Lines #3 thru #8 are only available using an optional expansion board which is not available
at this time.
An example configuration for the internal "CALL" switch is shown here.

Configuration of an Alarm Input

Select "Alarm Input" from the "Line Type" pull-down list.
You can give this input a Description of 15 characters or less. This is for your records only and
is not reported to the data collection system.
If the input is a normally-open switch then select Form-A. If the input is a normally-closed
switch then select Form-B. If you are combining lines together to create a KYZ input, then
select Form-C (Y-normally open) or Form-C (Z-normally closed). If you select Form-C for one
line then the next line will automatically be assigned as the other Form-C input and will inherit
the partner's settings. Allowed Form-C pairs are Lines-1&2, 9&10 and 11&12.
The "Debounce" setting, in combination with the "Sample Rates" setting on the OPTIONS
screen determines how long the switch needs to be closed or open before being considered a
"real" alarm event. Debouncing and sample rates are discussed in more detail later in this
document.
