To ensure your fire alarm system remains operational during a power outage, install a reliable backup power source, such as batteries or an uninterruptible power supply (UPS). Regularly test and replace batteries according to the manufacturer’s recommendations. Consider using a generator as an additional backup for prolonged outages. Schedule routine maintenance and inspections to verify all components, including backup power systems, are functioning correctly. Ensuring these measures are in place helps maintain continuous fire protection even during power disruptions.
