Audibility Assessment of Fire Alarm System Sound Level for Industrial Processes

Abstract

Fire alarm systems are the first stage of fire evacuation. The audibility of the fire alarm is of vital importance. In industrial buildings, there is almost continuous occupational noise. Variables such as duration, frequency, level and frequency range of this noise may vary depending on the work performed. In this study, the audibility of the fire alarm when it sounds during the process is evaluated. Audibility is based on the sound level. Sound levels for various processes were obtained from the literature. In our country, the sound levels of audible fire alarm systems are specified in the “Regulation on Fire Protection of Buildings”. According to this, the lowest alarm level is 65 dB(A), and the maximum total is 75 dB(A) with +10 dB(A) in places characterized as “noisy”. The maximum sound level allowed by the regulation is 120 dB(A). The sound level generated in the environment was calculated by calculating the fire alarm sound level and the sound levels of the processes together. The results show that the fire alarm sound level at the lower limit is not sufficient for process noise, while the fire alarm level at the upper limit corresponds to the “pain threshold”.
