Web alarm clock for 2:39 a.m.

You are midway through checking the gate log or watching the entrance when the 2:39 am alarm needs to pull you away for the guard change. That gives you 21 minutes to finish the current round, note anything unusual, and prepare a clear handover before 3:00 am. Set the alarm now so the shift change does not depend on repeatedly checking the clock.

A quiet gate can make it easy to miss where the alert will actually play. Before returning to your watch, check whether earphones or a Bluetooth headset are connected; the alarm may sound there without being obvious to you or the incoming guard. Raise the volume and test the alert through the output you intend to use. Keep this page active and the phone awake, because the guard change alarm cannot be relied upon after the browser is closed or the phone goes to sleep.

Once the handover is complete, avoid filling the remaining night with a task that could run into your next duty. Leave a small buffer for signing the log, returning keys or access cards, and walking back from the gate. If another job is due later the same day, set its reminder separately rather than stretching the 2:39 am alarm beyond this one changeover.
