Maererano neNational Fire Protection Association, kune moto unopfuura 354,000 wekugara gore rega rega, uchiuraya avhareji yevanhu vangangosvika zviuru zviviri nemazana matanhatu uye kukuvadza vanhu vanopfuura zviuru gumi nerimwe. Rufu rwakawanda runokonzerwa nemoto runoitika usiku kana vanhu vakarara.
Basa rakakosha rekuisa zvakanaka, kunaka kwehutsi maalarm ari pachena. Kune mhando mbiri huru dzezvitsigiro zveutsi -ionization uye photoelectric. Kuziva mutsauko uripo pakati pezviviri izvi zvinogona kukubatsira kuita sarudzo yakanakisa nezvehutsi maalarm kuchengetedza imba yako kana bhizinesi.
Ionizationchiutsi alarms uye maaramu emagetsi anovimba nenzira dzakasiyana zvachose kuona moto:

Ionizationzvitsigiro zveutsi dhizaini yakaoma kwazvo. Ane marata maviri anochajiswa nemagetsi nekamuri yakagadzirwa nemwaranzi inovheneka inoisa mhepo inofamba pakati pemahwendefa.
Maseketi emagetsi mukati mebhodhi anoshingairira kuyera iyo ionization ikozvino inogadzirwa neichi dhizaini.
Munguva yemoto, zvimedu zvinopisa zvinopinda mukamuri yeionization uye zvichiramba zvichiroverana uye zvinosanganiswa neiyo ionized mweya mamorekuru, zvichiita kuti huwandu hweiyo ionized mweya mamorekuru hurambe huchidzikira.
Maseketi emagetsi mukati mebhodhi anonzwa shanduko iyi mukamuri uye, kana chikumbaridzo chakafanotemerwa chapfuudzwa, alarm inotangwa.
Photoelectric utsi aramu
Photoelectric utsi aramu akagadzirwa zvichienderana nekuti utsi hunobva pamoto hunochinja sei kusimba kwechiedza mumhepo:
Kupararira kwechiedza: Mazhinji photoelectricmichina yeutsi shanda pamusimboti wekuparadzira chiedza. Ivo vane LED mwenje danda uye photosensitive chinhu. Chiedza chechiedza chinonangidzirwa kunzvimbo iyo iyo photosensitive element isingagoni kuona. Nekudaro, kana zvimedu zveutsi zvinobva mumoto zvichipinda munzira yemwenje wechiedza, danda rinorova zvimedu zveutsi uye rinodzoserwa mukati mechinhu chinopenya, zvichiita kuti alarm.
Kuvharika kwechiedza: Mamwe marudzi emagetsi maaramu akagadzirwa akatenderedza kuvharika kwechiedza. Aya maaramu anewo mwenje sosi uye photosensitive chinhu. Zvisinei, munyaya iyi, chiedza chechiedza chinotumirwa zvakananga kune chinhu. Kana zvimedu zveutsi zvavhara zvishoma mwenje wechiedza, kubuda kwephotosensitive mudziyo kunoshanduka nekuda kwekudzikira kwechiedza. Uku kudzikiswa kwechiedza kunoonekwa nekutenderera kwealarm uye kunokonzeresa alarm.
Musanganiswa maaramu: Pamusoro pezvo, kune akasiyana maalarm emusanganiswa. Kusanganiswa kwakawandazvitsigiro zveutsi batanidza ionization uye photoelectric teknolojia mune tariro yekuwedzera kushanda kwavo.
Mamwe masanganiswa anowedzera mamwe ma sensor, akadai se infrared, carbon monoxide, uye heat sensors, kubatsira kunyatsoona moto chaiwo uye kuderedza maaramu enhema nekuda kwezvinhu zvakaita seutsi hwekutambisa, mvura yekugeza, nezvimwe zvakadaro.
Misiyano Yakakosha Pakati peIonization uyePhotoelectric Smoke Alarms
Zvidzidzo zvakawanda zvakaitwa neUnderwriters Laboratories (UL), National Fire Protection Association (NFPA), nevamwe kuti vaone kusiyana kwakakosha kwekuita pakati pemhando mbiri idzi huru.michina yeutsi.
Mhedzisiro yezvidzidzo izvi uye bvunzo dzinowanzoratidza zvinotevera:
Photoelectric utsi aramu pindura kumoto unopfungaira nekukurumidza kupfuura maaramu eionization (15 kusvika 50 maminetsi nekukurumidza). Moto unopfungaira unofamba zvishoma nezvishoma asi unoburitsa utsi hwakawanda uye ndiwo unonyanya kuuraya moto mudzimba.
Ionization utsi maaramu anowanzo pindura nekukurumidza zvishoma (30-90 masekonzi) kumoto unopfuta (moto unopararira nekukasira) pane maaramu emagetsi. Iyo NFPA inoona iyo yakagadzirwa zvakanakaphotoelectric alarms kazhinji inodarika maaramu eionization mumamiriro ese emoto, zvisinei nerudzi uye zvinhu.
Ionization maaramu akatadza kupa yakakwana nguva yekubuda kakawanda kupfuuraphotoelectric alarms panguva yemoto unopfungaira.
Ionization alarms yakakonzera 97% ye "nuisance alarms"-nyevero dzenhema-uye, semugumisiro, vangangove vakaremara zvachose kupfuura mamwe marudzi ehutsi hwehutsi. NFPA inoziva izvozvophotoelectric utsi aramu Iva nemukana wakakura pamusoro peiyo ionization maaramu mukunyepedzera alarm senitivity.
Zvipi chiutsi alarm ndiyo yakanakisisa?
Kufa kwemoto kuzhinji hakusi kwemoto asi kufemerwa nehutsi, ndosaka nzufu zhinji dzine chekuita nemoto.-zvinenge zviviri muzvitatu-zvinoitika vanhu vakarara.
Zvazvakadaro, zviri pachena kuti zvakakosha zvakanyanya kuve ne chiutsi alarm iyo inogona kuona nekukurumidza uye nemazvo moto unopfungaira, unoburitsa utsi hwakawanda. Muchikamu ichi,photoelectric utsi aramu zvakajeka kupfuura maaramu eionization.
Mukuwedzera, musiyano pakati peionization uyephotoelectric alarms mumoto unopfuta wakaratidza kuve mudiki, uye NFPA yakagumisa kuti yemhando yepamusorophotoelectric alarms vachiri vanogona kukunda maaramu eionization.
Chekupedzisira, sezvo maaramu ekunetsa anogona kukonzera vanhu kudzimamichina yeutsi, vachivashayisa maturo;photoelectric alarms ratidzawo zvakanakira munzvimbo iyi, kusanyanya kubatwa nearamu dzenhema uye nekudaro kashoma kuve wakaremara.
Zviri pachena,photoelectric utsi aramu ndiyo yakanyanya kururama, yakavimbika, uye naizvozvo yakachengeteka sarudzo, mhedziso inotsigirwa neNFPA uye maitiro anogonawo kuonekwa pakati pevagadziri uye masangano ekuchengetedza moto.
Kune maalarm emusanganiswa, hapana chakajeka kana chakakosha mukana wakaonekwa. NFPA yakagumisa kuti mhinduro dzebvunzo hadzina kupembedza chinodikanwa chekuisa tekinoroji mbiri kanaphotoionization utsi aramu, kunyange zvazvo zvisiri hazvo kukuvadza.
Nekudaro, iyo National Fire Protection Association yakagumisa izvozvophotoelectric alarms nemamwe ma sensors, akadai seCO kana kupisa sensors, anonatsiridza kuona moto uye kuderedza maaramu enhema zvakanyanya.
