Abstract

The subject of the invention applies to the technical sector of detection means. The device comprises, in combination, suitably linked to inputs E1, E2 connected to detection members, a circuit for converting the detected signal and means arranged in order to: - on the one hand, when one of the inputs is activated and as a function of the duration of the detection, either drive alarm triggering members, or store the said signal for a predetermined time in such a way that, at the end of this predetermined time, no other detection having taken place on one of the inputs, the triggering members for the alarm are not driven and, conversely, if one of the inputs is activated, the triggering member or members are driven, - and, on the other hand, when the inputs are activated simultaneously, directly drive the alarm triggering member.
