Improvement in the structure of fire alarm systems' alarm bell stop switch

Abstract

Fire alarm systems are essentially installed on specific firefighting equipment and serve as one of the important alarm equipment that senses fire quickly and earlier than human beings. The main goal of this study is to nd methods for improving the structure of fire alarm systems. This study is concerned with false alarms of fire-indicating equipment in fire alarm systems. During the course of analysis, it was found that false alarms by fire alarm systems frequently occur and, also, fire safety managers neglect their duty of work by turning the alarm bell stop switch on, even during normal times. To prevent this, the alarm bell stop switch should be changed into an automatically resettable manual operation type so that it can automatically be reset to its original state, even though fire safety manager turns the switch on. As a result, this study provides aid for correcting fire safety managers' wrongful practices by making the alarm bell ring whenever an actual fire occurs; ultimately, false alarms are reduced by eliminating fundamental causes when false alarms occur.
