NFPA 111 Standard on Stored Electrical Energy Emergency and Standby Power Systems 2019
The 2019 edition of NFPA 111 is essential for contractors, designers, engineers, installers, and facility managers of any building that requires an uninterruptible power supply (UPS) according to NFPA 101®, Life Safety Code® or another code. In addition to improving occupant safety, compliance with NFPA 111 saves money by extending the life of the system through proper care.
Keep stored emergency power supply systems (SEPSS) reliable and safe with the 2019 edition of NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems. This resource is key anywhere a UPS is needed in the event of a disruption of the normal utility supply, and is loaded with information and advice that will support your work.
This Standard is used in industries such as finance, IT, and certain areas of health care — anywhere continuous emergency power is legally required and/or a loss of power is unacceptable, even for a short duration.
Poor maintenance of battery systems is a common cause of failure in SEPSS. NFPA 111 includes installation, maintenance, operation, and testing requirements as they pertain to the SEPSS performance. Provisions address every area of the system, including:
Accessory equipment needed to supply electrical power to selected circuits
NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems covers performance requirements for stored electrical energy systems providing an alternate source of electrical power in buildings and facilities during an interruption of the normal power source. It improves life safety through reliable SEPSS. (To enhance usability, this edition has been revised to cover the interruption time without reference to specific SEPSS types.)
