Input / Output Configuration; Alarm Input Parameters; Standard Alarm Descriptions - Honeywell CNI2 Operating And Installation Manual

The CNI2 has six (6) digital lines that can serve as alarm sensing or pulse-counting inputs, or as
outputs.
Four of the lines are available on four 2-pin MTA connectors J7, J9, J11 and J12, as shown
earlier. These are normally used as alarm-sensing inputs and are often prewired for specific
alarm triggers such as a magnetic TAMPER switch. However any of these can be configured
as pulse-counting inputs.
Two other lines are available on the "TB4" terminal block. These are most often used as pulse-
counting inputs but can also be configured as alarm-sensing inputs.
The inputs can be normally open (Form-A), normally closed (Form-B) or combined into a KYZ
(Form-C) configuration. When using Form-C connections there are certain lines that can be
grouped together.
An output can be used to control external equipment from the central office, such as a warning
light, an audio alarm or a pump (remote control of this output is only available when using the
®
DC-2009 data collection system). Or it can be configured as a "repeater", replicating any line
that is configured as an input.
An output has strict limitations with respect to voltage and current.
See the specifications section to avoid damage to the CNI2 board.

Alarm Input Parameters

An "alarm" is an event such as a switch closing or opening. The CNI2 reports the alarm
condition to the data collection system (DC-2009
