Civil siren of the French "Système d'Alerte et d'Information aux Populations" (SAIP), in case of a real danger. The signal consists of 3 distinct cycles, each lasting 1 minute 41 seconds. Each 61-second cycle is itself divided into 5 periods of sound, separated by 40 seconds of silence.
This creates a rising and falling sound designed to capture attention. In an emergency, the activation of these sirens is intended to inform citizens that they must immediately protect themselves, for example, by taking shelter indoors, closing doors and windows, and awaiting instructions from the authorities broadcast on the radio.
