- Ukuhlanganiswa ne-alamu yomlilo, i-paging ephuthumayo, kanye nokusebenza kwegumbi lokulawula kufanele kuhlolwe ngaphambi kokuthenga.
Ukukhetha isikhulumi se-ATEX sohlelo lwe-PA lwesipikha sendawo enobungozi kuyisinqumo sokuphepha, hhayi nje isinqumo sokuthenga umsindo. Ezindaweni eziqhumayo, imishini kumele ihambisane nokuhlukaniswa kwendawo kanye nomqondo wokuvikela ofanele, kanti izinhlelo zomsindo zezimboni kumele zilethe imiyalezo ecacile ngaphansi kwezimo zokusebenza zangempela. I-IEC 60079-0 ichaza izidingo ezijwayelekile zemishini yezindawo eziqhumayo, kuyilaphoI-IECExfuthiI-ATEXizinhlaka zisekela ukuhambisana kwemishini esetshenziswa ezindaweni eziyingozi. Ukuze kube nokwethenjelwa kokuxhumana, imigomo yokuzwakala kwenkulumo ivame ukuhlolwa ngezindlela ezifanaI-IECamazinga kanye nezilinganiso ze-acoustic zesayithi elithile, ngoba uhlelo olungafinyelela ku-110 dB ngaphandle kokucaca lungase lungasebenzi ngesikhathi esiphuthumayo.
Lokho Okumele Kwenziwe Yisikhulumi se-ATEX Endaweni Eyingozi Uhlelo lwe-PA
Isipikha se-ATEX kumele senze izinto ezintathu ngesikhathi esisodwa: ukusinda endaweni ezungezile, ukulandela imithetho yendawo eyingozi, futhi sihlale siqondakala lapho indawo inomsindo. Leyo nhlanganisela yingakho abathengi kufanele bagweme ukuphatha isipikha njengophondo olujwayelekile lwangaphandle.
Efektri yokuhluza, isitshalo samakhemikhali, indawo yokuphatha okusanhlamvu, noma idokodo lokupenda, isipikha sendawo eyingozi singaba yingxenye yesistimu yekheli lomphakathi, inethiwekhi ye-alamu ephuthumayo, noma uhlelo lokufaka ama-paging okuthutha. Isipikha kufanele sisebenze ngesikhathi sokusebenza okuvamile, kodwa futhi kufanele sihlale sithembekile ngezikhathi zezigameko ezifana nokuphazamiseka kukagesi, ukuphazamiseka kwenqubo, noma umsindo wangemuva oqinile. Ngaleso sizathu, imibuzo ebaluleke kakhulu akuyona nje kuphela ukuthi “Ingakanani umsindo?” kodwa futhi nokuthi “Iyiphi indawo eqinisekiswe ngayo?” kanye nokuthi “Ingabe opharetha bangawuqonda umyalezo ebangeni elihlosiwe?”
| Isici sokukhetha | Kungani kubalulekile | Indawo yokuqinisekisa evamile |
|---|---|---|
| Ukuhlukaniswa kwezindawo | Inquma ukuthi isipikha singafakwa kuphi | I-Zone 1, i-Zone 2, i-Zone 21, noma i-Zone 22 |

Yingakho amaqembu onjiniyela evame ukucela umdwebo wokuhlukanisa indawo enobungozi ngaphambi kokuba aqhathanise amazinga okukhipha umsindo.
Indlela Yokukala Isipikha Se-ATEX Sesistimu Yesipikha Sendawo Eyingozi
Usayizi wesipika kufanele usekelwe ekumbozweni nasekuqondeni, hhayi enombolweni eyodwa ye-wattage. I-horn engu-30 W kwelinye ilungiselelo ingase isebenze kangcono kuneyunithi engu-100 W kwelinye uma ukuphakama kokukhweza, i-engeli yokusabalala, kanye nephrofayili yomsindo we-ambient kuhambisana kangcono.
Insimu yomsindo ezindaweni zezimboni yakhiwe yimishini, amapayipi okuhambisa umoya, izindonga, amathangi, kanye namagceke avulekile. Uphondo olunomphetho omncane lungaphuma luqhubekele phambili eceleni komhubhe, kuyilapho iphethini ebanzi ingasebenza kangcono ekuhlanganiseni okuvulekile noma ezindaweni zokulayisha. Ngenxa yalesi sizathu, abathengi abanolwazi bacela ukuphuma kwe-dB ebangeni elithile, bese beqhathanisa nomsindo wendawo elinganisiwe. Uma isitshalo sinomsindo wangemuva ojwayelekile ongu-80 kuya ku-90 dB(A), ukudweba kufanele kuklanywe ngomkhawulo owengeziwe, ikakhulukazi lapho kugqokwe khona isivikelo sokuzwa.
Ukuzwakala kwenkulumo kungahlolwa ngezindlela eziqondile njengokuhlola ukuveza amagama kanye nokulinganisa indawo. Ekuxhumaneni okuphuthumayo, ukucaca komyalezo kuvame ukuba usizo kakhulu kunencazelo elula yomsindo ngoba abantu kumele baqaphele amagama anjengokuthi “phuma,” “yeka,” noma “hlanganisa” ngokushesha.
- Kala umsindo ozungezile ngesikhathi sokukhiqiza okuvamile kanye nokushintsha kwesimo esibi kakhulu.
- Thola indawo yokulalela ekude kakhulu kanye nanoma yiziphi izithiyo ze-acoustic.
- Cacisa uhlobo lomyalezo oludingekayo: ukubhalisa, isexwayiso, ukuphuma, noma imiyalelo yenqubo.
- Qinisekisa amandla e-amplifier, ukulahleka komugqa, kanye nokuzwela kwesipikha ndawonye.
- Hlola ukusebenziseka kahle ngemva kokufakwa, hhayi efektri kuphela.
Kumaphrojekthi amaningi, onjiniyela baqhathanisa nesilinganiso se-IP kanye nobubanzi bokushisa bokusebenza. Isipikha esisebenza kahle ngaphakathi singase singasebenzi kahle ngaphandle uma singakwazi ukusingatha imvula, ukuchayeka kwi-UV, inkungu kasawoti, noma ukujikeleza kokushisa. Yingakho i-auhla lwemikhiqizo yokuxhumana kwezimbonikufanele kubuyekezwe ngesicelo, hhayi ngegama lekhathalogi kuphela.
Idatha Yokusebenza Kwesipikha se-ATEX Okufanele Abathengi Bayihlole
Idatha yokusebenza iyindlela eshesha kakhulu yokuhlukanisa izimangalo zokumaketha nolwazi lobunjiniyela olusebenzisekayo. Kuhlelo lwe-PA lwesipikha sendawo esiyingozi, amanani amathathu abaluleke kakhulu: izinga lokukhipha, impendulo yemvamisa, kanye nokuqina kwemvelo.
Izinga lokucindezela komsindo livame ukushiwo ebangeni elithile, ngokuvamile imitha eli-1. Impendulo yemvamisa ikhombisa ukuthi isikhulumi siyaliphinda yini izwi ngokucacile phakathi nendawo lapho kuhlala khona amandla okukhuluma.
