Pulse Ext (s)
A pulse extension is used to prevent double triggers on a single alarm.
The pulse extension time starts on an alarm trigger. If that contact is
triggered again after the first alarm has finished but within the pulse
extension, the second trigger will not restart the alarm, but will extend
the current alarm duration. Enter the time in seconds for this extension.
Nuisance
This is a repetitive detector value. When an alarm is received on the
unit, it will store the alarm time and monitor the number of times the
same detector is triggered within an hour period. If the detector is
triggered the number of times entered here, the unit will de-activate this
detector from triggering an alarm for an hour. The unit will continue to
monitor the detector and check how many times it is triggered during
this period. If it is again triggered more than the amount set in the
nuisance counter, it will remain de-activated for another hour. This will
continue until the trigger value falls below the nuisance count setting.
To disable this feature, leave the setting as ‘0’.
Stuck Time (min)
If any of the alarms/detectors are active for a period longer than
specified here, they will automatically be omitted. This time period is set
in minutes.
Note: The arrow button displayed next to each textbox allows settings to be replicated for those
cameras listed below. This will only affect the adjacent option i.e. Enabled arrow will replicate the
Enabled setting to cameras below the clicked arrow.
