By law, fire alarm systems must be provided with certified batteries to operate during any emergency. There are a few options for choosing a reliable power supply and some calculations are necessary to ensure that the fire alarm system has sufficient backup power in the event of a power outage.
To provide a secondary power supply for a fire alarm system, you can use an emergency generator designed, installed, and maintained in accordance with NFPA 110, Standard for Emergency and Standby Power Systems. This generator provides power to the fire alarm system through an automatic transfer switch.
There are a few options for choosing a reliable power supply and some calculations are necessary to ensure that the fire alarm system has sufficient backup power in the event of a power outage. Batteries are a common way to provide a secondary power supply, and the most widely-used type is a valve-regulated sealed lead-acid battery.
Fire alarm batteries need to be sized to provide power to the entire system for 24 hours in standby and 5 minutes in alarm. If the system is an emergency voice alarm communication system (EVACS), then the batteries need to provide capacity for 15 minutes in alarm in addition to the 24 hours in standby.
Batteries are a common way to provide a secondary power supply, and the most widely-used type is a valve-regulated sealed lead-acid battery. These are typically located within the fire alarm control unit enclosure or in a nearby power supply unit.
Instead of providing two separate power supplies, you are permitted to provide power to a fire alarm system via a Stored-Energy Emergency Power Supply System (SEPPS), also known as an Energy Storage System (ESS) or an Uninterruptible Power Supply (UPS). The SEPPS must be configured in accordance with NFPA 111 and provide 24 hours of backup battery.
