A signalling device (41) to be worn on a person includes an emergency button (2) which triggers an internal transmitter (14) to transmit an encoded identification signal followed by audio signals picked up by a microphone (3). The transmitted signals are picked up by a control box (21) containing a radio receiver (19) which encodes the signals and commands an alarm box (24) to send out an audible and/or visual warning. Such warnings alternate with periods in which the alarm box broadcasts the audio signals picked up by the microphone (3).

Un dispositif de signalisation (41) porté par une personne comprend un bouton de secours (2) qui déclenche l'émission par un émetteur interne (14) d'un signal d'identification codé suivi de signaux audio captés par un microphone (3). Les signaux transmis sont captés par un boîtier de contrôle (21) contenant un récepteur radio (19) qui code les signaux et envoie une instruction à un boîtier d'alarme (24) d'émettre un avertissement acoustique et/ou optique. La diffusion desdits avertissements alterne avec celle des signaux audio captés par le microphone (3) et diffusés par le boîtier d'alarme.
