Runaway Alarm Monitoring
This feature requires the Enterprise version of Patriot, or the Enterprise Automated Alarm Handling module.
Patriot can detect runaway alarms (repeated signal from the same client). Patriot can raise an alert to notify operators, and optionally stop logging the repeated signals until the fault can be fixed.
Patriot tracks runaway events by counting the signals with the same Client Number, Type Number, Zone Number, and Module Number.
Runaway Profiles
A runaway profile holds the settings for runaway detection. Profiles can be configured from
Maintenance Menu > General > Runaway Profiles
The following modes of runaway detection are available in Patriot:
None
Runaway detection is disabled.
Sliding Window
A runaway is detected if more than Signal Limit identical signals are received within the Time Window.
Token Bucket
Patriot internally tracks a "Bucket" of remaining identical signals. Each signal removes one allowed signal from the bucket. A new allowed signal is added to the bucket every Replenishment Period.
If the bucket is empty when a new signal is received, a runaway alert is raised.
The token bucket mode can be better for detecting low-level runaways, where a large number of signals are being received but not at a rate high enough to trip the Sliding Window mode. The Replenishment Period should be set based on the maximum rate that you want to allow clients to log signals at, and the Bucket Size should be set to control the maximum size of 'bursts' of signals with an otherwise low rate (e.g. multi-area arm/disarm)
System Settings
Runaway monitoring must be enabled in Patriot's System Wide Data Service Settings
A Default Runaway Profile can be set, and Runaway Settings control what action is taken when a runaway is detected.
Client Settings
Runaway monitoring can be overridden for specific clients by changing the runaway profile on the Tests Tab
