How to use the online alarm clock
With the barge safely through, finish lowering the canal bridge and leave the controls at 8:25 am. An alarm at this time can mark the end of the lift, so checking gates, barriers and the control panel does not drift into the rest of the morning. The remaining 35 minutes before 9:00 am allow time for a final handover and a walk away from the canal.
For a bridge shift, the alert needs to be noticeable above engines, water and movement around the lock. The browser alarm may appear ready while the phone is on silent, yet its sound can still be suppressed by that setting, so a visible test beforehand clarifies what will happen. If the browser is put away or the phone goes to sleep, no alert will sound and the canal bridge handover could be missed; the alarm must remain active until it rings.
Leaving a control cabin early in the morning can mean moving from a bright screen into flat daylight or a shaded towpath. Before the 8:25 am alarm, reducing unnecessary screen brightness can make the display less glaring while keeping the digits readable. Once the bridge is secured, looking along the canal rather than straight back at the display gives the eyes a simple break before paperwork, keys or the walk to the next task.
Common questions
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.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
