How to use the online alarm clock
As another volunteer hands the neighbourhood patrol over to you, a 9:50 pm alarm can mark the moment to collect your coat, torch and keys. That leaves a short, useful gap before the 10:00 pm round begins, without relying on a hurried glance at the clock. It also gives the outgoing volunteer time to mention an open gate, an unlit path or anything unusual noticed nearby.
Your patrol cue needs an audible signal, so the browser alarm should be checked against the phone or laptop’s silent setting before you depend on it. A visible countdown alone may be easy to miss while you are listening to the handover or fastening a reflective layer. If you close this page or allow the device to sleep, the neighbourhood patrol can begin without the alarm sounding, so a separate phone alarm is sensible when the handover cannot slip.
Before stepping from a lit hallway into the darker evening, finish reading the patrol notes and then reduce the screen brightness. Keeping the display low while checking the route prevents a bright rectangle from dominating your view of the pavement, parked cars and house numbers. Once outside, putting the screen away between checks also leaves both hands free for the torch and any gate you need to open.
Common questions
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 9:50 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
