Batteries for Fire Alarm Systems

Q: Can you tell me where I could find the code reference for how often batteries serving fire alarm panels (booster panels, control panels, etc.) need to be replaced based on how old they are?

A: Currently, we are on the 2010 edition of NFPA 72, and Table 14.4.5 (6) (d) says sealed lead acid type batteries used on fire alarm systems need to be replaced 5 years after date of manufacturer, or more often as needed.

So, for now it is every 5 years after date of manufacturer.
