防(fang)盜門鈴(ling)壞(huai)了怎么辦(ban) 防(fang)盜門鈴(ling)維修方法大全
如(ru)(ru)果防盜門鈴(ling)不(bu)響(xiang),那么故障(zhang)可能來自于電(dian)(dian)(dian)路(lu)的(de)(de)任(ren)一(yi)部(bu)(bu)分——按鈕、門鈴(ling)或(huo)變(bian)壓(ya)器。變(bian)壓(ya)器是(shi)一(yi)種電(dian)(dian)(dian)氣(qi)部(bu)(bu)件,可將(jiang)110-120伏電(dian)(dian)(dian)壓(ya)逐步降低至門鈴(ling)的(de)(de)工作電(dian)(dian)(dian)壓(ya)10到18伏。除變(bian)壓(ya)器外,門鈴(ling)電(dian)(dian)(dian)路(lu)的(de)(de)所有部(bu)(bu)分都可以在不(bu)斷開電(dian)(dian)(dian)源的(de)(de)情況(kuang)下進行安全操(cao)作。如(ru)(ru)果您不(bu)知道電(dian)(dian)(dian)路(lu)的(de)(de)哪一(yi)部(bu)(bu)分出現故障(zhang),那么您需(xu)要準備以下維修(xiu)門鈴(ling)時需(xu)要使用的(de)(de)工具:
門鈴維修所需工具
1、螺絲刀
2、備用的按鈕、門鈴或變壓器
3、12伏萬用表
4、110-120伏萬用表或通斷檢(jian)測器
5、接(jie)線(xian)螺(luo)母或壓(ya)接(jie)連接(jie)
門鈴維修步驟
步(bu)驟(zou)1:拆(chai)下將門鈴(ling)按鈕固定(ding)在房屋上的螺釘。
步驟2:將按鈕(niu)拉出至電(dian)路連接(jie)線(xian)允許的長(chang)度,然后松開(kai)按鈕(niu)上(shang)的固定(ding)螺釘斷開(kai)電(dian)線(xian)。將兩根(gen)裸線(xian)端連接(jie)在(zai)一(yi)起。如果門鈴能響,您便可(ke)以(yi)知道(dao)故(gu)障位于(yu)按鈕(niu)中。通過將兩根(gen)電(dian)線(xian)連接(jie)到新(xin)按鈕(niu)的固定(ding)螺釘來安裝新(xin)按鈕(niu),然后重新(xin)將按鈕(niu)安裝到房屋(wu)上(shang)。門鈴按鈕(niu)是一(yi)種單(dan)極(ji)開(kai)關(連接(jie)了兩根(gen)電(dian)線(xian)),您可(ke)以(yi)將電(dian)線(xian)放(fang)置在(zai)各自(zi)的螺釘下。
步驟3:如果將兩根裸線(xian)端連接(jie)在一起后(hou)門(men)鈴不(bu)響,則故(gu)障可(ke)能在其他位(wei)置(zhi)——門(men)鈴組件、配線(xian)或(huo)變壓器。拆(chai)下門(men)鈴的卡(ka)口(kou)蓋(gai)(gai)板(ban)(ban),拆(chai)卸可(ke)能比預料的困(kun)難(nan)。由于(yu)有幾種(zhong)不(bu)同類型(xing)的蓋(gai)(gai)板(ban)(ban),因此可(ke)能必須(xu)嘗(chang)試幾種(zhong)步驟,嘗(chang)試稍微向(xiang)上(shang)抬(tai)起蓋(gai)(gai)板(ban)(ban)然后(hou)拉(la)出;如果不(bu)行(xing),請徑直拉(la)出蓋(gai)(gai)板(ban)(ban)而(er)無需先抬(tai)起蓋(gai)(gai)板(ban)(ban),或(huo)者查看卡(ka)口(kou)蓋(gai)(gai)板(ban)(ban)是(shi)否通過(guo)插腳(jiao)固定在門(men)鈴組件中。如果是(shi),那么請按下插腳(jiao)并(bing)拉(la)動蓋(gai)(gai)板(ban)(ban)使其松動。無論進行(xing)什么操(cao)作,切(qie)勿用力過(guo)猛,以免損(sun)壞漂亮(liang)的蓋(gai)(gai)板(ban)(ban)。
步驟4:拆下(xia)蓋(gai)板后(hou),請查找(zhao)兩個(ge)、三個(ge)或(huo)(huo)更多接線(xian)端和電(dian)線(xian),具體數(shu)量取決于您家的(de)門(men)鈴(ling)(ling)(ling)系統鳴(ming)響(xiang)(xiang)的(de)音調數(shu)。標準門(men)鈴(ling)(ling)(ling)或(huo)(huo)蜂鳴(ming)器(qi)有兩根電(dian)線(xian),可以通過(guo)松開固定螺釘(ding)斷開電(dian)線(xian),然后(hou)將電(dian)線(xian)連(lian)接到(dao)12伏的(de)萬用(yong)(yong)表上,或(huo)(huo)者(zhe)將電(dian)線(xian)連(lian)接到(dao)備用(yong)(yong)門(men)鈴(ling)(ling)(ling)的(de)固定螺釘(ding)上。廉(lian)價門(men)鈴(ling)(ling)(ling)、蜂鳴(ming)器(qi)或(huo)(huo)12伏汽車(che)用(yong)(yong)燈(deng)泡(帶有插(cha)座和兩根電(dian)線(xian))均可用(yong)(yong)于測試(shi)。如(ru)果按下(xia)門(men)鈴(ling)(ling)(ling)按鈕時測試(shi)門(men)鈴(ling)(ling)(ling)、蜂鳴(ming)器(qi)鳴(ming)響(xiang)(xiang)或(huo)(huo)燈(deng)泡亮(liang)起,那(nei)么您就必須安裝新門(men)鈴(ling)(ling)(ling)了。
步驟5:如果(guo)門(men)(men)鈴(ling)(ling)組件帶有三根或更(geng)多電線,請用遮蔽(bi)膠帶為它們做標(biao)記(ji):“T”表(biao)示變壓器,“2”表(biao)示前(qian)門(men)(men)門(men)(men)鈴(ling)(ling),“1”表(biao)示后門(men)(men)門(men)(men)鈴(ling)(ling)。松開(kai)固定螺釘(ding),拆下(xia)所(suo)有電線,然后將(jiang)標(biao)有“T”和“2”的(de)電線連接(jie)到(dao)測(ce)試(shi)(shi)門(men)(men)鈴(ling)(ling)或燈(deng)泡(pao)上(shang)的(de)螺釘(ding)接(jie)線端上(shang)。如果(guo)按前(qian)門(men)(men)按鈕(niu)時測(ce)試(shi)(shi)門(men)(men)鈴(ling)(ling)鳴(ming)響或燈(deng)泡(pao)亮起,那么(me)就是(shi)舊門(men)(men)鈴(ling)(ling)裝置存在故障。要(yao)檢驗此結(jie)論,將(jiang)標(biao)有“T”和“1”的(de)電線連接(jie)到(dao)測(ce)試(shi)(shi)門(men)(men)鈴(ling)(ling)上(shang)的(de)螺釘(ding)接(jie)線端上(shang)。如果(guo)按后門(men)(men)按鈕(niu)時門(men)(men)鈴(ling)(ling)鳴(ming)響,那么(me)就可以確定必須更(geng)換門(men)(men)鈴(ling)(ling)。
注:如果(guo)您的門鈴失靈了,故障可能(neng)出在電路中的任何一個(ge)部(bu)分,包括(kuo)按鈕、電鈴和變壓器。在從接線條上拆除(chu)任何電線之前,最好給(gei)它們標上記(ji)號(hao),以便(bian)能(neng)正確地將它們放回原位。
步驟6:如(ru)果門鈴(ling)(ling)不響或者按鈕(niu)或門鈴(ling)(ling)盒上(shang)的(de)燈泡不亮,那么兩者均是正(zheng)常(chang)的(de)。通(tong)過排除法,現在(zai)您可以知道故障(zhang)一(yi)定(ding)出在(zai)變壓器或配線(xian)(xian)上(shang)。通(tong)常(chang)會(hui)發現變壓器安裝(zhuang)在(zai)接(jie)(jie)線(xian)(xian)盒、副(fu)配電(dian)板(ban)或主接(jie)(jie)入配電(dian)板(ban)上(shang),門鈴(ling)(ling)電(dian)線(xian)(xian)連接(jie)(jie)到變壓器上(shang)露出的(de)固定(ding)螺(luo)釘(ding)上(shang)。將(jiang)測試(shi)門鈴(ling)(ling)直(zhi)接(jie)(jie)連接(jie)(jie)到露出的(de)低壓變壓器接(jie)(jie)線(xian)(xian)端上(shang),不要觸摸任何其(qi)他螺(luo)釘(ding)。如(ru)果門鈴(ling)(ling)不響的(de)話(hua),則是變壓器有(you)故障(zhang)或沒有(you)通(tong)電(dian)。
警告:變(bian)壓器(qi)直(zhi)接(jie)與電(dian)源連接(jie),它承載的(de)電(dian)流可能(neng)會使(shi)人受傷(shang)。在對變(bian)壓器(qi)進行操(cao)作(zuo)之前,請斷(duan)開(kai)為(wei)變(bian)壓器(qi)供(gong)電(dian)的(de)分支電(dian)路(lu)(lu)。拆下相(xiang)應保險絲或使(shi)相(xiang)應的(de)斷(duan)路(lu)(lu)器(qi)跳閘,或者操(cao)作(zuo)總開(kai)關以切斷(duan)家里的(de)總電(dian)源。
防盜門鈴維修
導致門鈴(ling)停止工作的原(yuan)因(yin)有很多,包括按鈕故障和電(dian)路損壞。
步驟(zou)7:更(geng)換變壓(ya)(ya)(ya)器(qi)之前,請檢查以確保其(qi)供電(dian)(dian)電(dian)(dian)路(lu)電(dian)(dian)壓(ya)(ya)(ya)為(wei)110-120伏。使電(dian)(dian)路(lu)斷電(dian)(dian),從線路(lu)電(dian)(dian)線斷開變壓(ya)(ya)(ya)器(qi)。然(ran)后再(zai)次(ci)接通電(dian)(dian)路(lu),并(bing)用110-120伏的(de)萬(wan)用表(biao)的(de)探頭(tou)與裸(luo)線端接觸。如(ru)果萬(wan)用表(biao)指示燈亮起或指示器(qi)讀數為(wei)110-120伏,則電(dian)(dian)路(lu)正常。
步驟8:如果(guo)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)有故障(zhang),請斷開電(dian)(dian)(dian)(dian)路(lu),然后(hou)拆下變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)。購買具有相同電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)和功率的(de)(de)(de)備用的(de)(de)(de)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)。在變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)上(shang)(shang)您(nin)可(ke)以找到(dao)壓(ya)(ya)(ya)(ya)(ya)印(yin)的(de)(de)(de)電(dian)(dian)(dian)(dian)氣(qi)信息,并且應該可(ke)以找到(dao)包裝(zhuang)上(shang)(shang)的(de)(de)(de)安裝(zhuang)說明,請按(an)照(zhao)說明小心操作。使用壓(ya)(ya)(ya)(ya)(ya)接連(lian)接器(qi)(qi)(qi)(qi)或接線(xian)(xian)螺母將新變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)與電(dian)(dian)(dian)(dian)氣(qi)系統的(de)(de)(de)電(dian)(dian)(dian)(dian)路(lu)電(dian)(dian)(dian)(dian)線(xian)(xian)連(lian)接,然后(hou)將門(men)鈴(ling)(ling)電(dian)(dian)(dian)(dian)線(xian)(xian)連(lian)接到(dao)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)的(de)(de)(de)低壓(ya)(ya)(ya)(ya)(ya)螺釘接線(xian)(xian)端,重(zhong)新打開電(dian)(dian)(dian)(dian)源,然后(hou)按(an)門(men)鈴(ling)(ling)按(an)鈕。如果(guo)已經正(zheng)確安裝(zhuang)變壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi),您(nin)應該能聽到(dao)門(men)鈴(ling)(ling)鳴響(xiang)。
步驟9:如(ru)果經(jing)驗證(zheng),變(bian)壓器(qi)及其電源電路(lu)均可正常工作,那(nei)么(me)只(zhi)可能是門(men)鈴(ling)配線(xian)的某處連(lian)接(jie)斷(duan)開或松動。沿著門(men)鈴(ling)電路(lu)從變(bian)壓器(qi)到門(men)鈴(ling)再到按鈕檢(jian)查(cha)線(xian)路(lu),查(cha)找是否存在松動的固定螺(luo)釘(ding)或電線(xian)接(jie)頭(tou)。如(ru)果這種(zhong)方(fang)法(fa)無法(fa)進行成功驗證(zheng),那(nei)么(me)您必須(xu)使用連(lian)續性測(ce)試儀(yi)檢(jian)查(cha)每一段電路(lu)。
步驟10:要測(ce)(ce)試(shi)(shi)每一段電(dian)(dian)(dian)路(lu),請(qing)斷開變壓器端的(de)門鈴(ling)(ling)電(dian)(dian)(dian)線(xian)以(yi)使(shi)門鈴(ling)(ling)電(dian)(dian)(dian)路(lu)斷電(dian)(dian)(dian)。請(qing)勿將(jiang)連(lian)續性測(ce)(ce)試(shi)(shi)儀用于通(tong)電(dian)(dian)(dian)電(dian)(dian)(dian)路(lu)。斷開門鈴(ling)(ling)端的(de)變壓器電(dian)(dian)(dian)線(xian),并將(jiang)它們(men)絞在一起以(yi)讓它們(men)相互(hu)接觸(chu)。返回變壓器處并使(shi)連(lian)續性測(ce)(ce)試(shi)(shi)儀的(de)探頭(tou)引線(xian)與門鈴(ling)(ling)電(dian)(dian)(dian)線(xian)的(de)裸露(lu)端接觸(chu),如果測(ce)(ce)試(shi)(shi)儀亮起或者(zhe)儀表(biao)(biao)刻度盤(pan)上有(you)讀數,則電(dian)(dian)(dian)路(lu)連(lian)續,且線(xian)路(lu)中(zhong)沒有(you)中(zhong)斷或連(lian)接松動,該部分電(dian)(dian)(dian)路(lu)完全(quan)正常。如果測(ce)(ce)試(shi)(shi)儀沒有(you)指示(shi),則表(biao)(biao)示(shi)某處可能中(zhong)斷了(le)。如果這段線(xian)路(lu)沒有(you)故(gu)障,請(qing)繼(ji)續測(ce)(ce)試(shi)(shi)下一段線(xian)路(lu),并以(yi)同樣方式檢查。
步驟11:如果電路(lu)中(zhong)存在斷(duan)路(lu),您(nin)必須試著找到它的(de)(de)位置(zhi)并加以維修。但(dan)是(shi)有(you)時,特別(bie)是(shi)大(da)量門鈴電路(lu)配(pei)線隱藏在墻(qiang)壁內(nei)或(huo)不便(bian)操作(zuo)的(de)(de)情(qing)況(kuang)下,最(zui)(zui)簡單(dan)的(de)(de)操作(zuo)過程是(shi)放(fang)棄原(yuan)來的(de)(de)配(pei)線線路(lu),沿著最(zui)(zui)方便(bian)的(de)(de)路(lu)徑鋪(pu)設(she)新的(de)(de)門鈴配(pei)線線路(lu)。
