Built for school first-aid teams, and equally at home with crisis teams, facilities staff and organisations running several sites. HOW IT WORKS Pick the room, describe the incident in one line, send. The alert goes to individual responders, to whoever is on the active roster, or to the whole team. The push notification overrides Do Not Disturb, responders see the location and accept or decline with one tap. Who was alerted, who accepted and who is on the way is visible live on one screen. FEATURES β’ Fast alerting: four seconds on average from trigger to alert, silent mode included β’ Duty rosters: recurring shifts that activate themselves, so you never alert the whole team again β’ Targeted: a preset per call type, so only the responders you need are alerted β’ Live status: acceptances, declines and replies as they happen β’ Escalation: if nobody responds, SaniAlarm widens the alert automatically β’ Chat during the call: coordinate inside the alert instead of in a separate app β’ Incident reports: the record is written during the call, not on paper afterwards β’ Roles and permissions: responders, office staff, teachers, leadership; set per person β’ Statistics: call volume and response times for whoever is accountable β’ Holidays and blackout periods: no alerts when nobody is on site PRIVACY Servers in the EU, encrypted transport, designed for use with minors.
