I’m pretty confident what’s occurring here is expected. I have also confirmed the behavior is the same in 7.9.13 as it is in 8.0.8. The first subscribed tag value after startup is considered an initial event, which by default doesn’t enter the notification system. These events will result in notifications _if_ “notify initial events” is enabled _and_ the minutes passed since shutdown exceeds the “continuous event detection window.” New active, unacknowledged events won’t be generated if this detection window hasn’t been exceeded, since the original alarm event prior to shutdown will be retained, hence why a notification isn’t sent. So to summarize, if these alarms are active on shutdown, and then the Gateway is restarted within the event detection window, it is expected (with default settings) that, on startup, the _prior_ event is loaded, and thus no new event occurs, hence why no notification is sent. If the Gateway is restarted outside the event detection window, _new_ events will be generated for these alarms, but won’t enter its pipeline if notify initial events is false. If the alarms _weren’t_ active on shutdown, then new events would be generated on startup (being that now active) and, similar to before, would only enter its pipeline if notify initial events is true. If you’re wanting new active events to be generated always on startup and for initial alarm events to enter their respective pipelines, then it would be best to set the detection window to 0 and notify initial events to true. Both of these Gateway settings are under the Event Suppression category in Alarming -\> General. --- _[View the full topic](https://forum.inductiveautomation.com/t/ignition-8-0-7-active-pipeline-not-triggered-for-the-first-time-each-alarm-occur/31304)._
