The battery size for a fire alarm system is typically calculated based on the system’s power requirements, which depend on factors like the number of devices connected, their power consumption, and the desired backup duration. A rough estimation might be a 12V battery with a capacity of around 7-12 ampere-hours (Ah) for a small residential system.
The battery must have enough capacity to power the fire alarm system for a specific period of time, typically 24 hours, without recharging. The size of the battery required depends on several factors, including the size and complexity of the fire alarm system and the expected duration of the power outage.
These are typically located within the fire alarm control unit enclosure or in a nearby power supply unit. Although a prevalent form of backup power supply, they need to meet specific requirements to be fit for purpose. All batteries installed in fire control panels must be as per recommendation of the fire panel manufacturer.
Battery capacity (Ah) = System standby current (A) x 24 hours The standby current refers to the amount of current the fire alarm system draws when it is not actively detecting a fire. This includes the power required to keep the control panel and any connected devices, such as smoke detectors, operational.
How long the system is required to run in the event of a mains failure. The general requirement for battery backup is that the system is to be able to run for 24 hours, then run in alarm for 30 minutes with an 80% charge in the batteries. (This is to allow for batteries not being fully charged, battery degradation etc.)
