Abstract

Oppfinnelsen angår en elektronisk tenningsanordning som inneholder et energilagringselement (5) som kan utløses over et detoneringsmiddel eller en tennsats ved hjelp av en aktuator eller bryter (6) for å initiere antenning. Energilagringselementet (5) blir matet fra en spenningsforsyner (4) som tilveiebringer en lav spenning når den ikke er aktivert, hvilken lave spenning leveres til en datasryredel (DST). I en beredskapsmodus økes forsyningsspenningens (4) spenningsverdi til et nivå som er tilstrekkelig for at antenning kan finne sted. En sikkerhetskode er lagret i en informasjonsdel (IT) i et ikke-flyktig lager (11). Beredskapsmodusen kan bare initieres dersom signalet som føres over tilslutningsledningen (AL) er i overensstemmelse med sikkerhetskoden. Oppfinnelsen sikrer derfor at ikke-autoriserte personer som ikke kjenner sikkerhetskoden, ikke er i stand til å bruke tenningsanordningen.
