NFPA 111 蓄电式应急电源和备用电源系统
 
1.1 Scope.
1.1.1* This standard shall cover performance requirements for stored electrical energy systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails.
1.1.2 Systems covered in this standard shall include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment, including integral accessory equipment, needed to supply electrical power to the selected circuits.
1.1.3 This standard shall cover installation, maintenance, operation, and testing requirements as they pertain to the performance of the stored emergency power supply system (SEPSS). 1.1.4 Exclusions.
1.1.4.1 This standard shall not cover the following
(1) Application of the SEPSS
(2) Distribution wiring
(3) Systems having total outputs less than 500 VA or less than 24 V, or systems less than Class 0.033
(4) Unit equipment
(5) Nuclear sources, solar systems, and wind stored-energy systems
(6) Uninterruptible power systems (UPS) supplied by an emergency power supply system (EPSS)
1.1.4.2 The following shall not be within the scope of this standard
(1) Specific buildings or facilities, or both, requiring an SEPSS
(2) Specific loads to be served by the SEPSS
(3) Type, class, or level to be assigned to any specific load (See Section 4.1.)
 
Get the facts you need to ensure availability of power during emergencies with the updated 2010 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. NFPA 111 covers power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to selected circuits. This Standard also covers 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 life safety and personal protection with 2010 changes and additions that include
·   Revisions of the document scope to clarify that UPSs supplied through a generator are not covered by the Standard
·   New definition and requirements for bridging systems
·   New definitions and requirements for battery cell types other than lead-acid, including nickel-cadmium (Ni-Cd) and nickel-metal hydride (NiMH)
·   New definition and requirements for electrochemical energy storage device to recognize that new stored energy technologies such as "ultracapacitors" are available and can be used as an SEPSS
·   Revisions for correlation with NFPA 110.
·   Revisions to Level 1 and Level 2 EPSSs clarifying the function and applicability of each level of system
·   Extensive revisions to Chapter 5 covering energy sources, convertors, inverters and accessories to clarify existing requirements, recognize new battery types, and provide requirements covering stored energy sources other than batteries
·   Revisions to the requirements for ventilation of areas containing electrochemical energy storage devices
