Mason,
Thank you for investigating and providing a comprehensive report on your findings.
Please let me know when we can coordinate troubleshooting the issue on site. We can probably coordinate it during the SCADA server upgrade site work.
Thank you,

Investigated the delayed callout response for the Influent Pumps UPS Trip alarm (UPS_0112_ON_BACKUP_Alm_TgtDisagree) that activated at 03:45:55 on 4/20/2026 and was not acknowledged until 04:03:37. Review of the WIN-911 logs showed that the alarm condition chattered repeatedly with very short active durations (5–7 seconds per occurrence) before clearing, and the assigned callout workflow ("Test 2") was configured to send notifications only when the alarm was in the Active + Unacknowledged state. Because the workflow's callout list cycles through contacts at one-minute intervals, each dispatch attempt evaluated the alarm state at the moment of dispatch — and since the alarm was inactive (but still unacknowledged) for the majority of the cycle, WIN-911 correctly skipped notifications to the District Call Out Phone, Mike Arias, and Mycal Jones contacts on multiple passes per the configured Send Notification settings. A successful dispatch eventually occurred to Mycal Jones at 03:54:58 when the workflow cycle happened to coincide with a brief active window; the call connected on each of four attempts but failed three times due to invalid authorization code entry on the receiving end before being acknowledged on the fourth attempt at 04:03:37. To prevent this filtering behavior from suppressing future callouts on chattering alarms, the Test 2 workflow's Notifications Behavior was updated to include both Active + Unacknowledged and Inactive + Unacknowledged states, ensuring the callout chain proceeds to completion based on acknowledgment status rather than instantaneous alarm state. It is additionally recommended that the underlying chatter on the UPS target/feedback disagreement signal be investigated at the source (PLC logic or UPS feedback wiring) to address the root cause.

Good Afternoon Kevin,
So this alarm was received by Mychal Jones around 3:45am Monday. The call did not go to the On Call phone and it did not go to my phone, which it should have gone to both before going to Mychal. Both phones were checked and there were no missed calls. Let us know what you find out. Thank you.
Kind regards,
Michael Arias
