The core function of automatic fire alarm system of fire fighting equipment is to find fire as soon as possible and start relevant alarm in time, fire prevention, smoke prevention and fire extinguishing equipment. It plays a very important role in discovering and controlling the initial fire of buildings. Technical fire prevention is an important means of building fire prevention. Any link of automatic fire alarm system in quality system selection, installation and commissioning will leave fatal problems to the system. There are construction hidden dangers in the automatic fire alarm system of some buildings, which directly restricts the linkage performance of the system and affects and threatens the fire safety of buildings and places.

一存在的問(wèn)題及原因：

I. existing problems and causes:

體系本身存在質(zhì)量缺陷或未針對(duì)具體場(chǎng)所選擇體系。在實(shí)際工作中，發(fā)現(xiàn)一個(gè)項(xiàng)目中報(bào)警系統(tǒng)的主機(jī)探測(cè)器和手動(dòng)警按鈕不是同一生產(chǎn)地，不是同一批次的產(chǎn)品，而是廠家便宜的設(shè)備，多個(gè)廠家的產(chǎn)品混入一個(gè)系統(tǒng)。此外，電子領(lǐng)域的競(jìng)爭(zhēng)非常激烈。為了保證企業(yè)的技術(shù)開(kāi)發(fā)利益，各廠家的產(chǎn)品技術(shù)參數(shù)不同，互不兼容。據(jù)對(duì)全市火災(zāi)自動(dòng)報(bào)警系統(tǒng)的調(diào)查統(tǒng)計(jì)，無(wú)法正常運(yùn)行的火災(zāi)自動(dòng)報(bào)警系統(tǒng)占總數(shù)的20%。

The system itself has quality defects or the system is not selected for specific places. In actual work, it is found that the host detector and manual alarm button of the alarm system in a project are not the same place of production or the same batch of products, but the cheap equipment of manufacturers, and the products of multiple manufacturers are mixed into one system. In addition, the competition in the electronic field is very fierce. In order to ensure the technological development interests of enterprises, the product technical parameters of various manufacturers are different and incompatible with each other. According to the investigation and statistics of the city's automatic fire alarm system, the automatic fire alarm system that cannot operate normally accounts for 20% of the total.

施工標(biāo)準(zhǔn)不高，導(dǎo)致系統(tǒng)功能無(wú)法正常發(fā)揮。從實(shí)際驗(yàn)收項(xiàng)目的情況來(lái)看，生產(chǎn)企業(yè)直接安裝調(diào)試的產(chǎn)品系統(tǒng)功能相對(duì)完整，而消防工程建設(shè)單位安裝調(diào)試的系統(tǒng)功能往往存在諸多缺陷。原因如下：

The construction standard is not high, which leads to the failure of the system function. From the actual acceptance of the project, the product system functions directly installed and debugged by the production enterprise are relatively complete, while the system functions installed and debugged by the fire engineering construction unit often have many defects. The reasons are as follows:

（1）消防工程施工單位機(jī)械地執(zhí)行規(guī)范與產(chǎn)品的結(jié)合點(diǎn)，導(dǎo)致系統(tǒng)綜合功能異常運(yùn)行，有的故意降低信號(hào)傳輸線的絕緣強(qiáng)度。（2） 在建筑上偷工減料。為了節(jié)約成本，一些施工單位人為減少了控制模塊，導(dǎo)致系統(tǒng)功能運(yùn)行異常，一些故障降低了信號(hào)傳輸線的絕緣強(qiáng)度。

(1) Fire engineering construction units mechanically implement the combination point of specifications and products, resulting in abnormal operation of system comprehensive functions, and some deliberately reduce the insulation strength of signal transmission lines. (2) Cut corners in construction. In order to save costs, some construction units artificially reduced the control module, resulting in abnormal system function operation, and some faults reduced the insulation strength of the signal transmission line.

3） 消防器材廠家施工單位不進(jìn)行系統(tǒng)調(diào)試或調(diào)試后系統(tǒng)功能無(wú)法較大化。常見(jiàn)的是，正當(dāng)功能無(wú)法實(shí)現(xiàn)。

3) The construction unit of fire equipment manufacturer does not conduct system commissioning or the system function cannot be maximized after commissioning. Often, legitimate functions cannot be realized.
