Alarm Setup
The Alarm Setup screen is used to configure the N-664’s six alarm inputs, and the
actions to be taken when any of these input is triggered. Each of the hardware alarm
contact inputs can have its trigger conditions and actions independently configured.
Alarm settings
Each alarm input has an associated user-settable text label. The alarm name label is
supplied along with the number when reporting the status of an alarm input to a Pilot
server. This label may be up to 15 characters long.
The Input Type setting selects if the normal (non-alarm) state is if the contact input is
closed or if the contact input is open. In Normally Open mode an alarm will be
registered when the two contact input terminals are shorted to each other. In Normally
Closed mode an alarm will be registered when the two contact inputs are not shorted to
each other. The default mode is Normally Open.
The duration setting sets a minimum time for which the alarm condition must be
maintained before an alarm is triggered. Setting the duration to “Static” will cause the N-
664 to trigger an alarm the moment it detects an alarm condition. If a longer duration is
selected the N-664 will not trigger an alarm until the input has been maintained
continuously for that duration.
