Ambient Music Level Allowed By Fire Alarm at Henri Blog

Ambient Music Level Allowed By Fire Alarm. 15 db above average ambient sound levels or 5 db above maximum ambient sound level (which ever is greater) allowances for reduction of audibility under certain conditions Where a continuous background noise level greater than 60db (a) is present the fire alarm signal should be 5db above the ambient, but not greater than 120db (a). The process of determining ambient sound levels for fire alarm systems in new construction involves assessing similar existing. Fire alarms must sound at least 15 db above ambient noise levels or 5 db above maximum ambient noise, whichever is greater, to ensure the alarm is audible throughout a building accounting for distance and sound absorption. Nfpa 72 states that audible fire alarm notification appliances used in the public mode must be a minimum of 15 db (decibels) above average.
