【正文】 icant loss of household assets, and some result in the neighbors, more heavy fire losses. Investigate the causes of fire in time, the vast majority of home fires happen parties said that the fire always feel that things are other people with their own far away, did not think this will happen even in the top of his head. Home fires are the main reason for negligent not to take timely preventive measures .In some of our large and mediumsized cities, almost every day family fires, fire prevention is so each family must always pay attention to. If your home based on the actual situation in advance to take simple fire prevention measures, a number of tragedies are entirely avoidable. Automatic fire alarm system is in order to inform the early detection of fire, and take effective measures to control and fight fires, and set in a building or other place of an automatic fire facilities, is that people with a powerful tool to fight the fire. Fire alarm system, fire detectors generally, regional centralized alarm alarm and position。 Jinxi ng sound and light alarm。這類傳感器響應速度快、靈敏度高、檢測特性好，但需要冷卻，使用不方便。 隨著現(xiàn)代家庭用火、用電量的增加，家庭火災發(fā)生的頻率越來越高。假如能根據(jù)您家的實際情況預先采取簡單的防火措施，一些悲劇是完全可以避免的。此外，也可以控制有關(guān)的滅火系統(tǒng)或?qū)⒒馂男盘杺鬏斀o消防控制室。不同類型的火災探測器適用于不同類型的火災和不同的場所。 火災報警控制器的基本功能主 要有：主電、備電自動轉(zhuǎn)換，備用電源充電功能，電源故障監(jiān)測功能，電源工作狀態(tài)指標功能，為探測器回路供電功能，控測器或系統(tǒng)故障聲光報警，火災聲、光報警、火災報警記憶功能，時鐘單元功能，火災報警優(yōu)先報故障功能，聲報警音響消音及再次聲響報警功能。系統(tǒng)電源除為火災報警控制器供電外，還為與系統(tǒng)相關(guān)的消防控制設備等供電。它以聲、光音響方式向報警區(qū)域發(fā)出火災警報信號，以警示人們采取安全疏散、滅火救災措施。 (二 )火災報警裝置 在火災自動報警系統(tǒng)中，用以接收、顯示和傳遞火災報警信號，并能發(fā)出控制信號和具有其它輔助功能 的控制指示設備稱為火災報警裝置。它能夠在火災初期，將燃燒產(chǎn)生的煙霧、熱量和光輻射等物理量，通過感溫。 火災報警系統(tǒng)，一般由火災探測器、區(qū)域報警器和集中報警器組成；也可以根據(jù)工程的要求同各種滅火設施和通訊裝置聯(lián)動，以形成中心控制系統(tǒng)。探討家庭火災的特點及防火對策， 對于預防家庭火災，減少火災損失具有現(xiàn)實意義 在現(xiàn)代城市家庭里，許多人因不懂家庭安全常識引起火災事故，使好端端的幸福家庭轉(zhuǎn)眼間毀于一旦 ,有的導致家破人亡 ,而且一旦發(fā)生居民家庭火災， 處置不當、報警遲緩 ,是造成人員受害的原因。熱探測傳感器是利用熱釋電效應的紅外探測器。 the same time supporting the implementation of appropriate control and many other tasks. Fire alarm system is a core ponent. In the fire alarm devices, some devices such as break, regional monitors, fire shows and other functions can not plete disc alarm device, which can be regarded as the evolution of fire alarm controller or supplement. Under certain conditions applied, and the fire alarm device fire alarm control belong. The basic function of fire alarm control are: the main power, backup power automatically converted, standby power charge function, power failure monitoring function, power functions working status indicator, power supply for the detector circuit function, control sensors or system failures, sound and light alarm, fire sound, light alarm, fire alarm and memory function, clock function unit, with priority being given fault function fire alarm, sound alarm sound audible alarm mute and again. (C) fire alarms in automatic fire alarm system to send different from the environment, sound, light the fire alarm sig
