Abstract

Alarm-trafo, som er en batterilader(l)/(9). karakterisert v/ at kretsen mellom et batteri(3) og en lydgiver(4) sluttes når ladestrømkretsen fil batteriet i utstyret som skal sikres blir brutt. Dette registrerer også nettspenningsbrudd, men det detekteres ved at en MCU(2) som drives av strøm fra transformatordelen(l) i batteriladeren, går over til å få sin driftstrøm fra batteri(3) hvis nettspenningen bortfaller, og da utløser alarmen pga. program(5). Elektronikken kan bygges inn i batteriladere, eUer legges inn som et meUomstykke(lO) meUom batteriladeren og utstyret som skal sikres.Alarm transformer, which is a battery charger (l) / (9). characterized in that the circuit between a battery (3) and an emitter (4) is terminated when the charging circuit circuit filing the battery in the equipment to be secured is broken. This also detects a power failure, but it is detected by an MCU (2) powered by the transformer part (l) of the battery charger to get its operating current from the battery (3) if the mains voltage fails, and then triggers the alarm. program (5). The electronics can be built into battery chargers, or inserted as a mill piece (10) between the battery charger and the equipment to be secured.
