须时刻注意的问题。假如能根据您家的实际情况预先采取简单的防火措施,一些悲剧是完全可以避免的。火灾自动报警系统是人们为了早期发现通报火灾,并及时采取有效措施,控制和扑灭火灾,而设置在建筑物中或其它场所的一种自动消防设施,是人们同火灾作斗争的有力工具。火灾报警系统,一般由火灾探测器、区域报警器和集中报警器组成;也可以根据工程的要求同各种灭火设施和通讯装置联动,以形成中心控制系统。即由自动报警、自动灭火、安全疏散诱导、系统过程显示、消防档案管理等组成一个完整的消防控制系统。火灾探测器是探测火灾的仪器,由于在火灾发生的阶段,将伴随产生烟雾、高温格火光。这些烟、热和光可以通过探测器转变为电信号报警或使自动灭火系统启动,及时扑灭火灾。区域报警器能将所在楼层之探测器发出的信号转换为声光报警,并在屏幕上显示出火灾的房间号;同时还能监视若干楼层的集中报警器(如果监视整个大楼的则设于消防控制中心)输出信号或控制自动灭火系统。集中报警是将接收到的信号以声光方式显示出来,其屏幕上也具体显示出着火的楼层和房间号,机上停走的时钟记录下首次报警时间性,利用本机专用电话,还可迅速发出指示和向消防队报警。此外,也可以控制有关的灭火系统或将火灾信号传输给消防控制室。火灾自动报警系统是由触发器件、火灾报警装置、火灾警报装置以及具有其它辅助功能的装置组成火灾报警系统按钮的火灾报警系统。它能够在火灾初期,将燃烧产生的烟雾、热量和光辐射等物理量,通过感温。感烟和感光等火灾探测器变成电信号,传输到火灾报警控制器,并同时显示出火灾发生的部位,记录火灾发生的时间。一般火灾自动报警系统和自动喷水灭火系统、室内消火栓系统、防排烟系统、通风
