alert system
Danger notification setup
An alert system is a mechanism for issuing warnings or notifications about dangers, emergencies, or important events.
The term covers everything from tornado sirens to smartphone emergency broadcasts to hospital codes: The alert system woke everyone at 3 a.m. with an Amber Alert.
Organizations also use alert systems for non-emergencies—stock price changes, software outages, or schedule updates.
