Which public alert system is used by emergency dispatch services to send recorded messages during an emergency?

The correct choice is Reverse 9-1-1, as it specifically refers to a system used by emergency dispatch services to deliver recorded messages directly to the public during emergencies. This technology enables authorities to inform residents about urgent situations, such as natural disasters, dangerous events, or other critical alerts in their area. The system can target specific geographic areas, ensuring that the right populations receive relevant information promptly.

In contrast, Code Red is a brand name for an emergency notification service that may assist in similar functions but is not the official term for the system used broadly by emergency dispatch services. The Emergency Broadcast System was an earlier version of a public alert system that has since been replaced by the Emergency Alert System (EAS) and does not use recorded messages in the same direct manner as Reverse 9-1-1. Alert Today refers to various public awareness campaigns but is not specifically tied to emergency messaging systems.
