| 요약2 |
In this study, voltage variation effects on sound level of fire alarm system were examine in the anechoic room and free field condition. Followings are results. Within the voltage band of ±20% from 24V(center) which is standard voltage, the sound pressure level is considered to be stable but in the condition of -20% below standard voltage, adequate sound pressure level is not assured. Acoustic equipment which is far from receiver can not fulfill standard sound pressure level output due to voltage dropping and this could cause a problem that fire alarm could not be heard to inhabitants. |
