Emergency Alarm
About the Emergency Alarm
Emergency alarms are intentionally rare and loud - fire drill at 2 PM exactly, must-leave shelter before curfew test, medication rescue window when minutes matter, or drill practice so real events are not the first test. Browser emergency alarms do not call 911; they scream locally so a procedure starts. Schools run tablet drills in classrooms; labs synchronize shutdown steps; caregivers practice evacuation timing with kids. Label must say EMERGENCY or specific drill name so household does not confuse with morning wake.
How to use it
- Reserve emergency label for true drills or critical windows only.
- Set exact time matching drill protocol or deadline.
- Use loudest tested sound and verify volume path.
- Brief household that test will occur.
- Disable immediately after drill or event concludes.
