What is the consequence of incorrectly calculating battery capacity for a fire alarm system, and how does it impact system reliability?

The consequence of incorrectly calculating battery capacity for a fire alarm system is that the system may fail to operate as intended during a power outage, severely compromising its reliability. Fire alarm systems are required to have a secondary power source, typically batteries, to provide power in the event of a primary power failure. Incorrectly calculating the battery capacity means the batteries may not be able to power the system for the duration specified by applicable ....
