In my recent NFPA® Live I discussed the selection and location of audible fire alarm appliances to help meet the audibility requirements of NFPA 72®, National Fire Alarm and Signaling Code®, 2019 edition. Participants learned the how to determine the minimum sound pressure level for the fire alarm system in a given space and how to account for the effects of hearing distance, wall configuration, and reverberation in the selection and location of audible notification appliances.
I received this follow-up question from a member. I hope you find some value in it.
