Online alarm clock for 11:37 am
Waiting for the emergency call-out departure at 11:37 am means watching the clock while the crew, vehicle and response gear stand ready. The alarm marks the assigned moment without making you repeatedly check the time. With 12:00 pm approaching, there is still a useful window to confirm the address, finish the handover and stay available rather than drifting into another task.
A call-out leaves little room to discover that the chosen signal is too quiet. Set the alarm early enough to play a test, then check that its tone is clear above conversation, radios and activity near the vehicle bay. If you close this page or allow the phone or computer to sleep, the alarm cannot sound, so the crew’s departure for the emergency call may be delayed. Leave the browser running on an awake device after the test.
As the crew waits through the final part of the morning, surrounding noise can rise as lunch breaks begin and people move through the station. Place the device nearby but away from paperwork or equipment that could cover its speaker, and use a distinct tone that will not blend into radio chatter. At 11:37 am, a brief, recognisable signal is easier to pick out than a soft sound that resembles another notification.
Common questions
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.
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.
