Raws li cov hauv paus ntsiab lus tshawb nrhiav, lub tswb hluav taws hauv tsev (cov khoom siv hluav taws xob) feem ntau muab faib ua photoelectric thiab semiconductor (los yog ionization) hom. Photoelectric pa luam yeeb detectors yog raws li lub hauv paus ntsiab lus ntawm optical scattering thiab siv lub teeb labyrinth tsim. Lawv rhiab heev rau cov pa taws loj uas tsim los ntawm cov hluav taws kub hnyiab, tab sis tuaj yeem ua rau lub tswb tsis tseeb vim dej vapor thiab plua plav. Semiconductor pa taws detectors yog raws li kev hloov pauv ntawm cov khoom siv hluav taws xob semiconductor. Lawv yog cov rhiab heev rau combustible gases thiab teb sai sai rau qhib nplaim taws, tab sis tej zaum yuav ua rau lub ceeb toom tsis tseeb vim lub chav ua noj fumes thiab cawv.
Phau Ntawv Qhia Kev Xaiv Tsev Hauv Tsev: Hauv chav ua noj ib puag ncig, photoelectric los yog dual- thev naus laus zis cov cuab yeej ntes tau raug txiav txim siab los txo cov tswb cuav; photoelectric tswb feem ntau yog ntsia hauv chav pw thiab chav nyob rau kev ceeb toom ntxov ntawm hluav taws kub; txoj kev hauv tsev thiab cov stairwells tuaj yeem ua cov nodes rau tag nrho - tsev txuas, xaiv photoelectric lossis ntau- cov khoom siv ntsuas.
Installation, Testing, and Maintenance: Nias lub xeem khawm tam sim ntawd tom qab installation; ua qhov kev sim ua haujlwm txhua hli; ntxuav lub tswb ntsuas cua txhua rau lub hlis; ua qhov simulated pa luam yeeb ib xyoos ib zaug; hloov lub roj teeb tam sim ntawd thaum qis; nws raug pom zoo kom hloov tag nrho lub tswb txhua txhua 10 xyoo.
Cov Qauv Tseem Ceeb: Cov khoom yuav tsum ua raws li cov qauv kev nyab xeeb thiab kev ua haujlwm thoob ntiaj teb, xws li US UL 217 tus qauv, NFPA 72 National Fire Alarm Standard, thiab Tuam Tshoj's GB 50166 "Kev Tsim Kho thiab Txais Cov Qauv rau Cov Hluav Taws Xob Hluav Taws Xob".
