Daylight Saving Time ends on Sunday, November 1, 2026, at 2:00 AM local time. Clocks move back one hour.

During past time changes, some AlarmAgent units had a temporary communication outage. During this outage, alarm notifications and data updates can be interrupted. Affected units show a Watchdog Alarm.

Beta Test Program: Firmware Update

We have developed a firmware update that we believe fixes this problem. The fix can only be fully tested during an actual time change, so we are offering it as a beta test program. We cannot confirm that it prevents the outage until after November 1.

If you want to join the beta test program and have your units updated before the time change, call AlarmAgent Support at 1-800-449-4539 and press 2 before Friday, October 30, 2026. Please have your company name and the names of your RTUs ready.

Before and After the Time Change

Because alarm notifications can be interrupted, check your units on the morning of November 1, including units that received the beta update. For critical sites, consider a site check until you confirm that your units communicate normally.

How to Check if Your RTU Is Affected

• Affected: Your RTU shows a Watchdog Alarm.
• Not affected: Your RTU's last communication time is after 10:30 UTC on November 1.

If you are not sure, poll the unit or wait for its next scheduled update.

How to Restore an Affected RTU

• Immediate fix: Power cycle the RTU. This forces a new server connection and restores communication right away. For instructions, see Resetting a unit experiencing a DST Watchdog.
• Automatic recovery: If you take no action, the unit reconnects within about 25 hours, during its normal daily sync with our servers.
