From catastrophic natural disasters to the threats our college students face, there has been a heightened demand for Mass Notification Systems (MNS) to provide clear, concise and intelligible voice messages that communicate how people should respond in an emergency. Manmade or natural, the magnitude and diversity of today’s threats have influenced the federal government and other organizations to create regulatory codes for Mass Notification and Emergency Communication Systems, including voice intelligibility requirements in order for these systems to be effective. International, European and North American fire alarm codes now require that voice evacuation systems meet minimum levels of speech intelligibility.
According to the British Standards Association (BSI), research shows that people who respond to a tone only signal take more than six minutes to evacuate a building with which they are not familiar; while those who hear a recorded voice message will be out in approximately four minutes. Live announcements are even faster at less than two minutes to evacuate.
This training course communicates to viewers the similarities and differences in the National Fire Protection Association (NFPA) low frequency sounder codes - NFPA 72 for fire signals and NFPA 720 for Carbon Monoxide (CO) signals - as it relates to sleeping room applications. Additionally, viewers will learn the different applications for sleeping rooms, solutions available and elements of system design.
