What is the purpose of a fire alarm system's battery backup?

The purpose of a fire alarm system's battery backup is to ensure the system remains operational during a power outage. In the event of a disruption in the power supply, such as during a storm or other emergencies, the battery backup allows the fire alarm system to continue to function. This capability is critical for maintaining safety, as fire detection and alerting mechanisms must be available at all times to detect fires and notify occupants even when the primary power source is unavailable.

Reliable operation during a power failure is essential because it prevents a potential scenario where a fire could go undetected, endangering lives and property. The battery backup system is designed to automatically switch on when the power goes out, ensuring that all monitoring, detection, and communication functions continue to work seamlessly. This feature is a vital component of any effective fire alarm system, contributing to overall fire safety strategies.
