One unified system to control it all
The Dallas Fort Worth International Airport (DFW) ranks as one of the top technology airports in the United States. One contributing factor is the completion of the most intelligible Public Address (PA) and Emergency Voice/Alarm Communications System (EVACS) in a domestic U.S. airport. While PA and EVACS have been around for many years, the design approach to combine them into one system is revolutionary. DFW’s renovation in International Terminal D was the beginning of a new standard, becoming the next generation EVACS for mass notification in the United States.
As one of the nation’s largest and busiest airports, up to 60% of all traffic at DFW is for connecting passengers. Inclement weather in any area of the country affects flights in and out of DFW, flight crews, passenger connections and more. “Being able to quickly make gate change announcements or page a passenger at the gate, terminal or entire airport saves time and gets the planes out of the gate,” says Rich Ashlin, American Airlines Managing Director of Customer Care at DFW. “Missed flights cost money and disruptions to our passengers’ business meetings, weddings, funerals, vacations and more.”
Merging the PA System and EVACS must include intelligibility per NFPA 72 (National Fire Alarm and Signaling Code). A merged system increases reliability and lowers maintenance costs.
Monitoring – While the EVACS system is rarely activated, the PA system is in continuous use and branch circuits consistently monitor for any failure, which automatically notifies the IT staff.
Architectural – A combined speaker system is aesthetically superior as there is no longer a need for two separate speaker systems.
Networkability – The combined system operates on a converged network switch and enables network technicians to monitor the entire system, examine usage, be quickly alerted to problems and benefit from an already secure, managed and proven converged network switching system.
Digital Control – In an emergency, the digital PA system can override regular announcements and pages to make sure the emergency announcements are played without interruption.
The combined systems can quickly restore airport operations to regular activity, providing cost savings to the airport and airline carriers.
