Description

Keep stored emergency power supply systems (SEPSS) safer and more reliable. NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems, covers the performance requirements for stored electrical energy systems that provide an uninterruptable power supply (UPS) in the event of a disruption of the normal utility supply. This standard includes installation, maintenance, operation, and testing requirements as they pertain to the system’s performance. In addition to improving occupant safety, compliance saves money by extending the life of the system through proper care and maintenance.
