Online alarm clock for 2:47 am
You are waking for a 2:47 am fire brigade duty alarm, before boots, radio and the rest of the shift have properly entered your thoughts. Settle on what must happen first, then use the short lead-in to 3:00 am to get dressed and check your roster details without rushing. During bushfire season, that quiet preparation can make the station handover feel less scrambled.
A firefighter coming off a rest period may not notice that earlier audio was routed to headphones left in a locker or beside the bunk. Before relying on this alarm, check the browser’s sound destination and play a brief test through the speaker you expect to hear. Keep the volume clearly audible over station activity. If the browser stops running or the computer goes into deep sleep, the alarm may stay silent, so fire brigade duty should also be covered by the station’s usual wake-up arrangement.
Late-night station noise can be deceptive around 2:47 am: a calm room may suddenly fill with a roller door, returning truck or radio traffic. Put the phone or computer close enough to distinguish the alarm from those sounds, but away from loose gear that could muffle it. Choose a tone unlike the radio alert, and leave the speaker uncovered so the changing background noise before 3:00 am does not disguise the signal.
Common questions
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.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
