摘要
文章以某建筑为例,研究了火灾报警系统误报警情况,随后分析了火灾报警系统出现误报警问题的主要原因。针对该问题提出了一种避免火灾报警系统因强电干扰发生故障的接口系统,避免了外部强电对火灾报警系统产生的电磁干扰,同时解决了火灾报警系统由于工作电压的不同产生电磁干扰而对火灾报警系统电缆产生干扰的问题。
The article takes a certain building as an example to study the false alarm situation of the fire alarm system,and then analyzes the main reasons for the false alarm problem in the fire alarm system.Aiming at this problem,an interface system is proposed to avoid faults in the fire alarm system due to strong electrical interference,which avoids electromagnetic interference caused by external strong electrical on the fire alarm system.At the same time,it solves the problem that the fire alarm system will cause electromagnetic interference due to the different working voltage,which will cause interference to the fire alarm system cable.
