How long does it take for fire alarm secondary power to activate?

The activation time for fire alarm secondary power is typically around 10 seconds. This timeframe allows for a sufficient period to ensure that the secondary power source, which is crucial for maintaining alarm functions during a power outage, can kick in reliably. The secondary power system is designed to seamlessly provide power to essential systems like control panels, notification appliances, and other critical components of the fire alarm system once a primary power failure is detected.

This activation time is standardized to ensure enhanced safety and reliability in fire alarm systems. A longer delay might increase the risk of failure to alert occupants in the event of an emergency, while a shorter time could lead to unnecessary activation due to momentary fluctuations in the power supply. Therefore, 10 seconds strikes a balance that allows the system to maintain functionality and respond promptly when needed.
