An arrangement for use in a safety notification system includes primary and secondary power sources and a voltage converter. The primary power source provides power to a notification appliance circuit of a notification system. The secondary power source includes at least one battery. The voltage converter is coupled between the battery and the notification appliance circuit of the notification system, and is configured to generate a regulated DC voltage from an output voltage generated by the second power source. In general, the secondary power source is employed when the primary power source is not available or otherwise is not functioning. However, the secondary power source may also be employed in other circumstances.

L'invention concerne un agencement pour utilisation dans un système de notification de sécurité qui comprend des sources d'alimentation primaire et secondaire et un convertisseur de tension. La source d'alimentation primaire fournit une puissance à un circuit de système de notification d'un système de notification. La source de puissance secondaire comprend au moins une batterie. Le convertisseur de tension est couplé entre la batterie et le circuit de système de notification du système de notification et est configuré pour générer une tension en courant continu régulée à partir d'une tension de sortie générée par la seconde source d'alimentation. En général, la source d'alimentation secondaire est employée lorsque la source d'alimentation primaire n'est pas disponible ou sinon ne fonctionne pas. Toutefois, la source d'alimentation secondaire peut également être employée dans d'autres circonstances.
