style="text-indent:25px">報(bào)警器一直響怎么解除：煙霧報(bào)警器由總線供電，與火災(zāi)報(bào)警控制器聯(lián)網(wǎng)、通訊組成一個(gè)報(bào)警系統(tǒng)，報(bào)警時(shí)現(xiàn)場(chǎng)無聲音，主機(jī)有聲光提示。煙霧報(bào)警器是技術(shù)先進(jìn)，工作穩(wěn)定可靠的傳感器，被普遍運(yùn)用到各種消防報(bào)警系統(tǒng)中，性能遠(yuǎn)優(yōu)于氣敏電阻類的火災(zāi)報(bào)警器。不少朋友不知道煙霧報(bào)警器一直響怎么解除，介紹解除煙霧報(bào)警器的方法。可能是有灰塵、蚊蟲進(jìn)入煙霧報(bào)警器，其需要經(jīng)常清理，尤其是放在灰塵、粉塵相對(duì)較大的地方。如果有小蟲子鉆進(jìn)煙霧迷宮，也會(huì)影響芯片感應(yīng)，引起誤報(bào)。可能是電池欠壓，無線報(bào)警器不同于傳統(tǒng)的有線產(chǎn)品，需要經(jīng)常人工挨個(gè)檢查是否欠壓。煙霧報(bào)警器本身具有自我巡檢，欠壓報(bào)警的功能，當(dāng)報(bào)警器一直響時(shí)，可能是電池欠壓了。</p><p style="text-indent:25px">可燃?xì)怏w報(bào)警器正確的使用方法：1、探測(cè)器不能在可燃?xì)怏w濃度高于下限的環(huán)境條件下使用。因?yàn)榇呋紵蜋z測(cè)器使用的檢測(cè)元件是載體催化活性元件，檢測(cè)可燃?xì)怏w濃度高于下限的濃度時(shí)，將燒壞探測(cè)器內(nèi)的檢測(cè)元件。　　2、注意不要使探測(cè)器意外進(jìn)水或受水蒸氣噴射。因?yàn)樘綔y(cè)器中的檢測(cè)元件進(jìn)水后會(huì)影響其性能，如果意外進(jìn)水，要重新更換探測(cè)器內(nèi)的檢測(cè)元件。安裝于室外的探測(cè)器則應(yīng)裝有防雨罩。　　3、探測(cè)器安裝位置的高低要與被測(cè)氣體的密度相適應(yīng)。比空氣輕的氣體總是向上擴(kuò)散，檢測(cè)器應(yīng)安裝在泄漏源的上方。安裝高度應(yīng)高出釋放源所在高度0.5～2m，且與釋放源的水平距離適當(dāng)減小至5m以內(nèi)，可以盡快地檢測(cè)到可燃?xì)怏w。比空氣重的氣體，應(yīng)安裝在泄漏源的下方，且安裝高度應(yīng)高出地面0.3～0.6m。過低易造成因雨水淋濺對(duì)探測(cè)器的損害，過高時(shí)超出了比空氣重的氣體易于積聚的高度。報(bào)警器安裝報(bào)警探測(cè)器的時(shí)候，主機(jī)必須安裝在有電源線、電話線的地方。</p><div

style="text-indent:25px">催化燃燒式報(bào)警器：對(duì)于這類報(bào)警器線性較好，也就是說做顯示會(huì)有準(zhǔn)確性，但是缺點(diǎn)是壽命不長的問題，雖然有些廠家聲稱催化燃燒式報(bào)警器壽命可以到5年或者更多，但實(shí)際使用環(huán)境中都有許多不穩(wěn)定性氣體，這樣就會(huì)使壽命會(huì)變短。工業(yè)上使用的進(jìn)口催化燃燒式報(bào)警器對(duì)客戶保證的壽命是3年，但是，根據(jù)實(shí)際應(yīng)用情況反映，催化燃燒式報(bào)警器使用半年就不行了。半導(dǎo)體報(bào)警器：半導(dǎo)體報(bào)警器優(yōu)點(diǎn)是反映靈敏，簡單講就是輕而易舉就能檢測(cè)到燃?xì)庑孤┑膯栴}，報(bào)警器可以很**知，并且迅速報(bào)警。但是缺點(diǎn)線性方面做的不完善，因此，幾乎沒有人用半導(dǎo)體報(bào)警器來檢測(cè)濃度問題。半導(dǎo)體報(bào)警器較大的優(yōu)點(diǎn)是壽命長，目前市場(chǎng)上的半導(dǎo)體報(bào)警器國內(nèi)外一些產(chǎn)品都可以做到4—5年使用壽命，甚至有些質(zhì)量過硬的產(chǎn)品可以用的更久。報(bào)警器的安裝位置不能靠近燃?xì)庹?，智能燃?xì)鈭?bào)警器非常的靈敏，高溫會(huì)使其變形甚至故障。寧波聯(lián)氨報(bào)警器廠家推薦</p><p

style="text-indent:25px">因此要降低誤報(bào)警，從人防方面著手是不可少的。其中建立報(bào)警信息確認(rèn)機(jī)制可減少出警的次數(shù)。報(bào)警中心收到報(bào)警信息后，應(yīng)先對(duì)報(bào)警主機(jī)下發(fā)確認(rèn)信號(hào)，表示中心已接收，而報(bào)警主機(jī)在沒有收到確認(rèn)信號(hào)時(shí)，應(yīng)重發(fā)。在技術(shù)方面，運(yùn)用多種手段對(duì)報(bào)警信號(hào)進(jìn)行確認(rèn)，如安裝多個(gè)探測(cè)器（普遍使用的是雙紅外+紅外加微波），當(dāng)多個(gè)探測(cè)頭同時(shí)探測(cè)到入侵信號(hào)時(shí)才向主機(jī)發(fā)送報(bào)警信號(hào)，從而降低誤報(bào)率。另外，國家也可制定一些有關(guān)誤報(bào)警的法規(guī)，像國外一些地方國家，對(duì)報(bào)警用戶或安防公司采取檢查、罰款、懲罰等措施，如在一定時(shí)期內(nèi)報(bào)警次數(shù)超過規(guī)定的數(shù)量將進(jìn)行罰款。這對(duì)人為誤報(bào)可起到一定的制約作用。寧波聯(lián)氨報(bào)警器廠家推薦</p><p>
