Emergency notification system

An emergency notification system is a method of facilitating the one-way dissemination or broadcast of messages to one or many groups of people, alerting them to a pending or existing emergency. The Emergency Notification System (ENS) was created by Dialogic Communication Corporation (DCC) in the early 1980s. DCC, including its patent portfolio, was purchased by Motorola Solutions as part of their 2018 acquisition of Airbus DS Communications.
