NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems
NFPA · National Fire Protection Association
Companion to NFPA 110 for stored-energy alternate sources (UPS and battery systems) that supply power when normal power fails.
On this page
Overview
NFPA 111 covers performance requirements for emergency and standby power systems that run on stored electrical energy. It is a companion to NFPA 110 and deals with alternate sources that supply power when normal power fails. The current edition is 2025; the next edition is planned for 2028 and sits in the Annual 2027 revision cycle.
Its scope includes power sources, transfer equipment, controls, and supervisory and accessory equipment. In practice it matters for US projects where UPS and battery systems serve emergency or standby functions. The standard aims to make sure these systems deliver the expected performance when needed.
This record rests only on NFPA's public standard development page; the text was not read. Related documents include NFPA 110, IEC 62040-3 and NFPA 855.

Using it in design
- In the UPS module (US profile), when a UPS feeds emergency or standby loads, record its stored-energy class (runtime) and test regime.
- Keep the IT UPS and life-safety stored-energy systems as distinct objects.
- Add a step to the design checklist to determine whether NFPA 110/111 applies in the project's jurisdiction.
