Abstract

The present invention relates to an alarm system making it possible to detect and signal intrusion into premises. According to the invention, the alarm system comprises a unit 2 for detection of intrusion into premises, a unit 3 for sending an alarm signal put into action as a consequence of the detection of an intrusion and a unit 4 for putting the detection unit, as well as the corresponding electrical connections, onto standby, the whole assembly being housed in the same casing 5. The invention applies to alarm systems.
