Get the latest on stored emergency power supply systems in the 2013 NFPA 111.

Readiness of emergency power is a key consideration in safeguarding building occupants in the event of a disruption of the normal utility supply. NFPA 111: Standard on Stored Electrical Energy Emergency and Standby Power Systems covers performance requirements for stored electric energy systems providing an alternate source of electrical power in buildings and facilities during an interruption of the normal power source.

Requirements in NFPA 111 address:

• Power sources
• Transfer equipment
• Controls
• Supervisory equipment
• Accessory equipment needed to supply electrical power to selected circuits
• Installation, maintenance, operation, and testing requirements as they pertain to the performance of the stored emergency power supply system (SEPSS).

Stay up-to-code and maximize safety with new options for stored power systems.

Changes in the 2013 edition include the addition of a rectifier plant -- commonly used in the telecommunications industry -- as a potential stored emergency power supply system, or as a suitable bridging system.
