Switch luhternak transistor chuahnak he aa thenmi himnak khamnak, cu switch pehtlaihnak asiloah naihnak in luhternak thawngthanhnak kha a thleidan i a kuat chuahnak transistor he ttihnung hmun ah himnak hmun ah a thlen himnak khamnak chungin. Line palhnak hmuh khawhnak cu Module cunglei ah LED. Module i a dial thlennak cu hman a si luhnak le chuahnak kha a tthen chung asiloah a hnulei uknak chiah awk, cun onh awk ah asiloah line palhnak hmuh khawhnak alarm langhternak riantuannak kha phih.
Hi thilri nih hin a dang tein thazaang peknak a herh, a dang tein thazaang peknak he pekchanhnak, luhternak le chuahnak terminal hna.

Line palhnak hmuh khawhnak (LFD)
Hmantu hna nih module cunglei ah "ON" lei kha an thim khawh palhnak hmuh khawhnak riantuannak kha tuah khawh awk le ralrinnak langhter awkah LED ceunak sen. Hmun ah luhternak current>7mA, short circuit alarm (SC); Hmun ah luhternak current
pehtlaihnak luhternak nih palhnak hmuh khawhnak rian a herh (hri a kiak, a tawi circuit), 22k Ω resistor cu a donghnak pahnih ah aa tluk tein pehtlaih a si lai switch, le 680 Ω resistor cu a hnu hnu in pehtlaih a si lai (as switch pehtlaihnak II caah hri suaimi ah langhter a si).
