    Abstract:The significance and current situation of the automatic fire alarm systems used in the fast-developing high-rise buildings are introduced briefly,and the influence of the voltage loss on the automatic fire alarm system is proposed. Meanwhile,the main factors for the voltage loss on the power line of the automatic fire alarm system are analyzed,and the measure to choose the power line more reasonably at different power supply distances is summarized by calculating and deducing the voltage losses of the automatic fire alarm systems in the high-rise residences,in order to provide the reliable circuit guarantee for the automatic fire alarm system.
