Cov pa taws ceeb toom cawm neeg txoj sia. Raws li National Fire Protection Association (NFPA), muaj lub tswb pa taws zoo hauv koj lub tsev tuaj yeem txo koj txoj kev pheej hmoo tuag hauv hluav taws los ntawm 55 feem pua.

Tab sis ua li cas lub tswb ceeb toom ua haujlwm hauv thawj qhov chaw?
Cov pa taws ceeb toom pom cov khoom hauv huab cua. Lawv feem ntau siv ob hom kev tshawb nrhiav los ua qhov no.
Ua ntej, muaj ionization detectors. Lawv siv ib qho me me ntawm cov khoom siv hluav taws xob tiv thaiv kev nyab xeeb los them, lossis ionize, huab cua molecules ntawm ob daim hlau. Qhov no tsim ib qho me me tam sim no ntws hauv huab cua los ntawm ib lub phaj mus rau lwm qhov. Thaum cov khoom nkag mus rau hauv lub chamber, lawv nyiam ions thiab nqa lawv mus, txo cov dej ntws tam sim no. Thaum cov khoom txaus nkag mus rau hauv lub chamber kom txo qis tam sim no hauv qab ib qho nyiaj, lub cuab yeej sau npe cov khoom raws li cov pa luam yeeb thiab lub tswb yuav nrov. (Dab tsi txog cov khoom siv hluav taws xob? Feem ntau ntawm nws cov hluav taws xob thaiv hauv lub cuab yeej, thiab txawm tias tom qab ntawd, cov hluav taws xob hauv cov cuab yeej tau qis dua li cov hluav taws xob hauv qab ntuj uas peb raug rau txhua hnub.)
Lwm cov cuab yeej siv los tshawb pom yog hu ua photoelectric. Cov thev naus laus zis ua haujlwm los ntawm kev tshawb pom lub teeb pom kev los ntawm cov khoom hauv ib lub teeb nyob rau hauv ib chav sensing chamber. Thaum tsis muaj cov khoom muaj nyob rau hauv lub tshuab nqus tsev, lub teeb los ntawm lub teeb tsis cuam tshuam lub photodetector, qhia tias txhua yam yog qhov qub. Lub tswb nrov thaum muaj cov khoom nyob thiab cov teeb pom kev los ntawm lub teeb pom kev nce mus txog theem pib.
Ob lub tshuab ntes tuaj yeem ntes cov hluav taws kub "smoldering" qeeb lossis kub kub "flaming" sai, tab sis txhua lub tshuab muaj nws tus kheej qhov zoo. Ionization-raws li ceeb toom yuav ntes cov me me dub soot hais nyob rau hauv cov nplaim taws sai dua vim hais tias lawv raug tsim nyob rau hauv ntau dua thiab nqa tam sim no los ntawm nruab nrab ntawm daim hlau. Photodetectors zoo li yuav rhiab heev rau cov khoom loj, dawb lossis xim xim, thiab yog li muaj kev cuam tshuam ntau dua, xws li cov hluav taws kub hnyiab.
NFPA pom zoo tias tib neeg muaj ob qho tib si ionization thiab photovoltaic li hauv lawv lub tsev. Dual-sensor tswb uas ua ke ob lub thev naus laus zis kuj muaj.
Thaum lub tswb ceeb toom pa taws tseem ceeb rau kev tiv thaiv koj tsev neeg thiab cov khoom ntiag tug, ntau zaus lawv tuaj yeem ua teeb meem. Cov pa taws ceeb toom ze ntawm chav ua noj tuaj yeem ntes cov khoom uas poob tawm thaum nws ua noj, txawm tias koj tsis hlawv nws. Qee zaum, qee yam yooj yim li tig lub toaster tuaj yeem ua rau lawv zoo siab.
Zoo li ntau yam kev ntsuas kev nyab xeeb, cov pa luam yeeb tuaj nrog kev lag luam tawm. Lawv tuaj yeem nkag siab txaus los kuaj pom yuav luag txhua yam pa luam yeeb. Tab sis yog tias lawv ua, lawv tuaj yeem ntes cov pa luam yeeb uas koj tsis xav kom lawv ntes (xws li los ntawm cov zaub mov siav), lossis lwm yam xws li plua plav. Cov cuab yeej ntsuas tsis tshua muaj peev xwm ua kom muaj kev ceeb toom tsawg dua, tab sis hauv qhov hluav taws kub tiag tiag lawv yuav tsis tshwm sim rau lub sijhawm los cawm txoj sia lossis khoom. Los yog tej zaum lawv yuav tsis teeb liab kiag li.
Cov kws tshawb fawb tab tom tsim cov kev ntsuam xyuas tshiab thiab cov qauv tsim kom muaj lub tswb ceeb toom kom pom cov pa luam yeeb uas peb xav kom lawv ntes, ntau dua li cov pa luam yeeb uas peb tsis xav kom lawv ntes, yog li peb tsis txhob sim kaw lub tswb thiab yuav tso koj tus kheej ntawm kev pheej hmoo. Raws li qhov tshwm sim, cov cim tom ntej ntawm cov pa luam yeeb tau cog lus tias yuav txo qis cov tswb nrov thaum tseem ceeb tshaj qhov hluav taws kub sai dua. Thaum tua hluav taws, lub sijhawm yog txhua yam thaum nws los cawm lub neej thiab khoom.
