Ukuhlelwa kweealam zerhasi ezinokutsha

Isixhobo se-alamu yegesi evuthayongokuhambelana nokusetyenziswa kokusingqongileyo kunokwahlulwa kwisixhobo se-alarm yegesi enokutsha kunye nesixhobo se-alarm yegesi yasekhaya, ngokwendlela yayo inokwahlulwa ibe sisixhobo esisisigxina se-alam yegesi evuthayo kunye nesixhobo esiphathwayo se-alam yegesi enokutsha.
I-alamu yerhasi esisigxina esisigxinaIsixhobo ngokubanzi senziwe sisilawuli se-alarm kunye ne-detector, umlawuli unokubekwa kwigumbi lomsebenzi, ngokukodwa ukulawula indawo yokubeka iliso, i-detector ifakwe kwigesi evuthayo inokuthi ivuze indawo yamacandelo angundoqo izinzwa zegesi ezitshayo ezakhelwe ngaphakathi, izinzwa zokubona ukuxinana kwegesi emoyeni. Inzwa ibona i-concentration yegesi emoyeni. I-detector iguqula i-concentration yegesi efunyenwe yi-sensor ibe ngumqondiso wombane kwaye uyithumele kumlawuli ngekhebula. Iphezulu i-concentration yegesi, inamandla umqondiso wombane; xa i-gas concentration ifikelela okanye idlula indawo ye-alarm ebekwe ngumlawuli we-alamu, i-alamu ithumela isignali ye-alarm, kwaye inokusebenza i-valve ye-solenoid, i-fan exhaust kunye nezinye izixhobo zokufikelela ukuphelisa iingozi ezifihliweyo ngokuzenzekelayo.
I-alam yerhasi ephathwayo enokutshangokubamba ngesandla, abasebenzi banokuthwala, ukufumanisa iindawo ezahlukeneyo zoxinaniso lwerhasi etshayo, isethi yegesi ephathwayo yokulawula, ii-detectors kwenye. Xa kuthelekiswa ne-alamu yegesi emiselweyo, umahluko ophambili kukuba umtshini wegesi ophathwayo awukwazi ukudityaniswa nezinye izixhobo.
