A life safety system (10) with a micro-controller (12) that is programmed to operate both a visual signal (14) and an audible signal (16). One feature of the system is that a user is permitted to enter a temporal signaling mode for not only the audible signal (14), but also the visual signal (16). The program includes an energy saving routine (32) that operates the visual signal (14) in the temporal mode with an energy consumption that is substantially smaller than required for operation in a continuous mode (62, 64). The temporal pattern has four cycles with one flash pulse per cycle for the first three cycles and no flash pulse for the fourth cycle.

L'invention concerne un système de sécurité des personnes (10) muni d'un microcontrôleur (12) qui est programmé pour actionner un signal visuel (14) et un signal audible (16). Une des caractéristiques du système permet à un utilisateur d'introduire un mode de signalisation temporel non seulement pour le signal audible (14) mais aussi pour le signal visuel (16). Le programme comprend une routine d'économie de l'énergie (32) qui actionne le signal visuel (14) en mode temporel, et ce avec une consommation de l'énergie sensiblement inférieure à ce que demande le fonctionnement en mode continu (62, 64). Le schéma temporel comporte quatre cycles, avec une impulsion de flash par cycle pour les trois premiers cycles et aucune impulsion de flash pour le quatrième cycle.
