Esikhathini esidlule, lezo zikhathi ezingathandeki, lapho iminyango yokungena ingavaliwe, noma ivikelwe ngu-ugogo-concierge, isivele ihambe. Namuhla, noma yimuphi indlu ehloniphekile noma encane ine- interphone system emnyango, evumela, kungakhathaliseki ukuthi uqobo, ukuvimbela ukubonakala kwabantu abangabazi emnyango. Ikhanda elingasese lanoma yiluphi uhlelo olunjalo luyisikhiye sombane esivimba ngokuphepha umnyango uvaliwe. Mayelana nezici zokuxhuma ilokhi yomakhalekhukhwini, sizokhuluma namhlanje.
Indlela yokuxhuma ukukhiya magnetic ku-intercom?
Okokuqala, ake sibone ukuthi kungenzeka yini ukuba sibhekane nokuxhumeka kwe-intercom ngokukhiya kwe-electromagnetic ngaphandle kokubandakanyeka kochwepheshe. Kungakhathaliseki ukuthi bazama kanjani ukusiqinisekisa eminyangweni yokukhangisa ephindaphindiwe yezinkampani ze-intercom, akukho lutho oluyinkimbinkimbi ekufakweni okunjalo. Into esemqoka ukugcina imithetho elandelayo:
- Kokubili i-intercom kanye nokukhiya kwe-electromagnetic, futhi izinto zokufakelwa kufanele zenziwe ngumkhiqizi ofanayo. Lokhu kuzokusiza ukugwema izinkumanga ezingathandeki ngendlela yokungahambisani nobukhulu bezingxenye noma ukungabi nalutho kwezakhi ezibalulekile zesifunda.
- Uma usebenza, ungakhohlwa ngemithetho yokuphepha kagesi.
Kule ndawo yonke, ngesimiso sokuxhuma kanye nethuluzi elifanele, ngisho nenkosi engenazibalo ingakwazi ukusingatha ukufakwa kwekhibhodi ye-electromagnetic yomakhalekhukhwini.
Ake sicabangele isinyathelo ngesinyathelo ukuthi umakhalekhukhwini uhlobene kanjani nokukhiya kombane:
- Phakamisa umzimba wenqaba. Ngokwemvelo, lokhu kukhiya kunamakhi amabili: ingxenye yomzimba, ekhonjiswe emnyango wesango, kanye nehange elibekiwe emagqabini omnyango. Uma lezi zici ezimbili zihlangene, kuvela insimu ye-electromagnetic egcina umnyango uvaliwe. Uma isibonakaliso sivela kumlawuli wokulawula, i-voltage esuka ku-lock isusiwe, insimu yamagnetic iyanyamalala futhi umnyango uvula. Futhi uma isifunda singafaki ukunikezwa kwamandla okungaqondakali, ke umnyango
izovulwa futhi uma ugesi luqedwa. Ukuze uqinisekise ukuthi zonke izakhi zomsebenzi wesistimu ngokuthembekile, uma uthengela ilokhi, kufanele ukhethe umthwalo ofanele okwakhiwe ngawo (ongakwazi ukubamba) kanye nomnyango oseduze (isici esinikeza ukuvala okushelelekile nokuthula). Ngesikhathi sokufakwa, qiniseka ukuthi i-armature nomzimba ziphikisana ngqo nomunye futhi banesikhala esincane esimweni esivaliwe. - Sixhuma ihange lokukhiya kuphaneli yokulawula. Kule nkinga, izintambo ezisetshenziselwa ukufakwa kumele zibe nesigaba esinqamule esifana nemingcele yokukhiya nokuthembeka efakwe kwiphubhu ewonakele.
