Two worries come up in almost every conversation with principals: "What if the internet goes?" and "What if the power goes?" They have different answers.
When the internet goes down
A well-designed cloud bell should not depend on the internet to ring. RoboticBell stores its schedules and audio on the device itself and runs in both online and offline modes. When the internet drops, it keeps ringing from the last saved timetable. Internet is needed only to push new schedule changes from the cloud and to fetch new AI content — both resume automatically when the connection returns.
Question to ask any supplier: "If I unplug the router, will tomorrow's bells still ring?" The answer should be yes.
When the power goes out
Here the weak link is usually not the bell controller but the amplifier. Bells, music and announcements play through your P.A. system — if the amplifier has no power, no one hears anything, whatever the controller does.
- Put the amplifier and the bell controller on the same backup — a UPS or the school inverter circuit — so both stay on during a cut.
- Check that the backup lasts the school day for the typical length of outages in your area.
- For gong or siren systems, the gong itself needs power to ring; include it on the backup circuit too.
- After a long outage, check the controller shows the correct time and schedule.
Keeping time after an outage
Basic timers can lose their time or programme when power fails. With a cloud-programmable bell, the schedule is stored safely on the device and in the cloud, so it is not lost, and staff can check it from a phone. See also why bells ring at the wrong time.
Checklist
- Schedules stored on the device — rings with no internet
- Amplifier and controller on UPS or inverter
- Gong or siren on backup power, if you use one
- A staff member knows how to check the schedule from a phone
