BS 5839-1 requires the recording of sounder levels in commercial buildings. Specifically, the standard mandates that the sound level of fire alarm sounders must be at least 65 decibels in general areas and at least 75 decibels at bed-head locations when doors are closed. In smaller areas, such as stairwells or enclosed spaces, the sound level can be reduced to 60 decibels. #firealarm #firealarminstallation #professional #firesystem #smoke #smokealarm #fireprotection
