Customer Alarm-1; Customer Alarm-2; Magnetic Or "Call" Switch Alarm - Honeywell CNI2 Operating And Installation Manual

CNI2 Operating and Installation Guide
The Nuisance Limit can be used to disable calls due to a repeating alarm condition. As an
example, say the CNI2 is scheduled to call in every 12 hours. One of the alarm inputs comes
from a pressure sensor which has become defective. Until the sensor is repaired the CNI2 will
keep calling in every couple of minutes to report a the pressure alarm. This is especially
undesirable for battery-operated units because each call consumes power. But if you set the
Nuisance Limit to 3 then DC-2009 will instruct the CNI2 to stop calling in after the third report of
the same alarm. Later, when the CNI2 calls in at its regularly-scheduled time (12 hours later),
the Nuisance Limit will be reset and the unit will again be allowed to report the alarm up to 3
times until the next scheduled call.
The SAVE checkbox allows the alarm condition to be recorded in the database. The LOG
checkbox allows the alarm to be reported to the computer's printer or screen. The ALERT
checkbox will activate the printer's audio alarm if a printer is used.
For each alarm be sure to select the APPLY button after you make any changes.
Note: Changes made to any alarm configuration will not go into effect until the next
communication with the CNI2.
Here is a general list of the alarms supported by the CNI2. You can change the description of
each alarm to more accurately describe its purpose. For instance "Customer Alarm 1" could be
changed to "High Pressure".
Most electrical switches have only two contacts and are either normally-open (Form-A) or
normally-closed (Form-B). A third configuration, Form-C, contains two switches, one of each
type.

Customer Alarm-1

If Line #1 has been configured as a Form-A or Form-B alarm input the alarm will be reported as
a "Customer Alarm-1" alarm.
If the combination of Line #1 & #2 has been configured as a Form-C alarm, then the alarm
condition itself will be reported as a "Customer Alarm-1" alarm. If a switch failure is detected,
the failure is reported as a "Customer Alarm-2" alarm.

Customer Alarm-2

If Line #2 has been configured as a Form-A or Form-B alarm input the alarm will be reported as
a "Customer Alarm-2" alarm.
If the combination of Line #1 & #2 has been configured as a Form-C alarm then see the
discussion for the Customer Alarm-1 alarm.

Magnetic or "CALL" Switch Alarm

If Line #9 has been configured as a Form-A or Form-B alarm input the alarm will be reported as
a MAGNETIC SWITCH or CALL SWITCH alarm.
If the combination of Line #9 & #10 has been configured as a Form-C alarm, then the alarm
condition itself will be reported as a MAGNETIC SWITCH or CALL SWITCH alarm. If a switch
failure is detected, the failure is reported as a TAMPER alarm.
