The secondary power supply capacity required shall include all power supply loads that are not automatically disconnected upon transfer to the secondary power supply. True or False?

The statement is true because when designing a fire alarm system, it is crucial that the secondary power supply’s capacity accounts for all loads that will remain connected during a transfer to secondary power. This ensures that in the event of a primary power failure, the system can maintain functionality and support all necessary components, including alarms, notification appliances, and any other critical devices that are vital for safety and emergency responses.

By considering all non-disconnectable loads, designers can adequately size the secondary power source, ensuring reliability and compliance with safety standards. This approach not only preserves system integrity during outages but also complies with regulatory requirements that mandate certain components remain operational for effective fire management and response.
