Il est réalisé sous la forme d'un dispositif d'émission et de réception porté par le propriétaire (de préférence, un téléphone mobile avec un dispositif Bluetooth ® à faible portée) et de dispositifs d'émission et de réception d'articles à protéger fixés sur ces articles (de préférence, sous la forme d'étiquettes avec des dispositifs Bluetooth). La signalisation d'alarme est mise en oeuvre de façon suivante : le téléphone transmet périodiquement, par l'intermédiaire de canaux de communication établis par les dispositifs Bluetooth du téléphone et des étiquettes, des codes de signalisation d'alarme uniques à chaque étiquette et se présentant comme des séries de signaux radio d'alarme d'interrogation comprenant un ensemble de séries d'intervalles de répétition pour chaque étiquette « Ti » et des intervalles de répétition de signal d'alarme radio « ti », « i » correspondant au numéro de l'étiquette; le dispositif reçoit les signaux de retour et les décode. En outre, le téléphone active des signaux d'alarme qui identifient les étiquettes à alarme activée après l'expiration de périodes prédéterminés « t(wi) » de transmission et de réception en retour par le téléphone des signaux d'alarme radio codés, ces périodes étant comptées à partir du moment que le téléphone envoie les premiers signaux d'alarme dans la série égales à t(wi) = (0,7 – 1)T(i) si, pendant ces périodes, le téléphone n'a pas reçu au moins un signal radio de retour avec un code de signalisation d'alarme non affecté à partir de chacune des étiquettes. Le résultat technique permet une meilleure protection des articles dans une zone de protection à courte portée de 1 à 3 mètres et une meilleure résistance de l'alarme aux interférences.
