A Fire Alarm Mass Notification System is an emergency alert system designed to notify large groups of people in case of emergency, such as a fire. This system uses a combination of audio, visual and text messages to quickly and effectively communicate critical information to affected parties. It is comprised of three components – the controller, the distribution nodes, and the interface – and it works using monitored signals from smoke detectors, heat harnesses and other detectors that are configured with the system. With a Fire Alarm Mass Notification System, notifications are sent out swiftly and reliably to ensure that everyone in the building is aware of potential danger as soon as possible.
