What type of systems require standby power according to NFPA standards?

Standby power is essential for various fire alarm and signaling systems to ensure they remain operational during a power outage or if the primary power source fails. The National Fire Protection Association (NFPA) standards outline that all types of systems, including central station systems, remote station systems, and household systems, must have standby power. This requirement is crucial because these systems must continue to function and effectively protect life and property, regardless of external conditions affecting power supply.

Central station systems must be monitored and responsive to emergencies even when there is a loss of utility power, and remote station systems also need to maintain communication with monitoring services. Likewise, household systems, which protect residential dwellings, are equally critical during power failures. Therefore, the inclusion of standby power for all these systems underscores the importance of reliability and the necessity of maintaining safety measures at all times. This holistic approach ensures comprehensive protection in various settings, meeting the safety standards established by NFPA.
