Online alarm clock for 2:45 am
As you hand the security site over to the next guard, a 2:45 am alarm can mark the final check without making you watch the clock. It leaves a clear quarter-hour before 3:00 am for passing on keys, access details and anything unusual noticed during the shift.
For this security handover, the alarm needs an audible path rather than relying only on what appears on screen. Check the volume and make sure silent mode will not suppress the alert, especially if the phone was muted earlier in the night. Keep the browser page active and the phone awake until it rings; if either is shut down beforehand, the security shift change may pass without a sound. A short test tone at a low level can confirm the setting without creating unnecessary noise.
Leaving a night shift at 2:45 am can affect people at home who are still asleep, so choose an alarm sound that is distinct but controlled. Place the phone close enough for the outgoing guard to hear it promptly rather than turning the volume high across the room. Once the incoming guard has taken over, dismiss the alarm before gathering gear or opening doors, keeping the early-hours handover quieter for the household.
Common questions
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
