Isishwankathelo
Isithintelo sokhuseleko esizimeleyo esineziphumo zokutshintshwa kwegalelo lokutshintsha, olukwahlulayo kunye nokuhambisa imiqondiso yegalelo ukusuka kubafowunelwa bokutshintsha okanye ukutshintshwa kokufutshane kwiindawo ezinobungozi ukuya kwindawo yokhuseleko kunye nemveliso yokuhanjiswa ngomqobo wokhuseleko. Ukufunyanwa kwempazamo yomgca kufezekiswa nge-LED phezulu kwimodyuli. Ukutshintshela ukucofa kwemodyuli kusetyenziselwa ukuseta igalelo kunye nemveliso kwisigaba okanye umva wolawulo, kunye nokwenza okanye ukukhubaza umgca wokubona impazamo yokubona umsebenzi we-alarm.
Le mveliso ifuna unikezelo lwamandla oluzimeleyo, kunye nonikezelo lwamandla olulodwa, igalelo, kunye neetheminali eziphumayo.

Phawula:
Ukufunyanwa kwempazamo yomgca
Abasebenzisi banokukhetha icala elithi "ON" lokutshintsha phezulu kwimodyuli ukwenza umsebenzi wokubona iimpazamo kwaye ubonise i-alamu ngokukhanya okubomvu kwe-LED. Kwi-site input current>7mA, i-alarm yesiphaluka esifutshane (SC); Kwi-site input current
