Alerting systems are tools designed to notify individuals or groups about important events or emergencies. They can be used in various settings, such as businesses, hospitals, and public safety. These systems often utilize methods like text messages, emails, or loud alarms to ensure that the intended audience receives timely information. These systems can be automated or manual, depending on the needs of the organization. For example, fire alarms automatically trigger alerts when smoke is detected, while emergency notification systems may require a person to send out alerts during a crisis. Overall, alerting systems play a crucial role in enhancing safety and communication.
