A fire alarm system is designed to ensure reliability and functionality during emergencies, which necessitates at least two sources of power. The primary source typically comes from the building’s electrical supply, while the secondary source is usually a battery backup. This redundancy is crucial because it allows the system to remain operational even if the primary power source fails, such as during a power outage.

In many jurisdictions, including Ohio, codes and standards dictate this requirement to enhance safety measures. Compliance ensures that fire alarm systems can maintain their operational integrity under various conditions, thus providing continuous monitoring and responding capabilities. The combination of both sources is essential to ensure that an alarm will sound if necessary, regardless of electrical conditions within the facility.
