  • Description

    Keep stored emergency power supply systems (SEPSS) more reliable and safer with the 2022 edition of NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems.

    NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, is key anywhere an uninterruptable power supply (UPS) is needed in the event of a disruption of the normal utility supply. This standard covers the performance requirements for stored electrical energy systems that provide an alternate source of electrical power in buildings and facilities during an interruption of the normal power source. It is used in industries such as finance, IT, and certain areas of health care—anywhere continuous emergency power is legally required or a loss of power is unacceptable, even for a short duration.

    Improve life safety with reliable SEPSS.

    Poor maintenance of battery systems is a common cause of failure in stored emergency power supply systems (SEPSS). NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, includes installation, maintenance, operation, and testing requirements as they pertain to the system's performance. The provisions address every area of the system, including the following:

    • Power sources
    • Transfer equipment
    • Controls
    • Supervisory equipment
    • Accessory equipment needed to supply electrical power to selected circuits

    This edition has been revised to incorporate NFPA 855.

    The 2022 edition of NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, is essential for designers, engineers, contractors, installers, and facility managers of any building that requires a UPS according to NFPA 101®, Life Safety Code®, or any other code. The new edition also introduced some changes to align with the first edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems.

    In addition to improving occupant safety, compliance with NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, saves money by extending the life of the system through proper care and maintenance. (Print, Approx. 26 pp., 2022)
