Evaluating Data and Voice Signals in Pathway Survivable Cables for Life Safety Systems

This month, the Fire Protection Research Foundation, NFPA’s research affiliate of NFPA published a report titled: “Evaluating Data and Voice Signals in Pathway Survivable Cables for Life Safety Systems” to determine if temperature impacts the transmission and the functional and operational quality of alarm/data signals and voice messages in a fire rated and non-fire rated environment. If temperature does have an impact, the research team was tasked with identifying the critical temperature and time at which the transmission of alarm/data signals and voice messages are no longer understandable to provide technical basis for any changes to NFPA 72, National Fire Alarm and Signaling Code® and NFPA 1225, Standard for Emergency Services Communications . Check out the one-page summary which highlights the project tasks and findings or read the report in its entirety. If you are attending the NFPA 2022 C&E, be sure to come to the education session discussing this Foundation project on Tuesday, June 7 at 8am in Room 153ABC. See you there!
