Recently, an electrical contractor on-site at a mission critical project was having difficulties with the integration of the emergency lighting inverters with the power monitoring system.

He looked at the large uninterruptible power supply UPS sitting adjacent to it and remarked about unnecessary pieces of equipment and why he should mess around with the pesky little 10 kW units when there were 2-MW generators supporting kW UPS systems.

Surely, the nfpa 110 2013 understands the differences in the code and listing requirements of the emergency nfpa 110 2013 optional standby systems.

However, his point was also clear. Due to the bulk of attention on and the much higher cost of the mission nfpa 110 2013 power standby system, it sometimes seems the emergency systems lag behind. In this example, the life safety system was segregated from the standby system to simplify the overall system design and operation.

It was also segregated to prevent the need nfpa 110 2013 have the mission critical loads served from the same generator as life safety loads. That segregation was to simplify the overall power system while meeting the necessary codes.

This article explains that decision-making process. Reviewing applicable codes nfpa 110 2013 standards It is important to understand how different sources of information interact and affect the overall design of a facility.

Understanding the individual sources of information provides a basis for understanding how to bridge the gaps between them, and it minimizes confusion and conflicts.

The following select codes and standards required to properly specify, design, and install emergency and standby systems typically involve these three primary areas: NFPA defines the minimum requirements for equipment needed to support life safety systems, such as elevators, exit signs, and emergency lighting.

This code nfpa 110 2013 on other codes, such as the NEC and NFPAto provide information on how those systems should be nfpa 110 2013 and how they should perform.

The NEC is primarily concerned with installation requirements and safety. While it defines some nfpa 110 2013 requirements, it does nfpa 110 2013 list specific requirements for performance, testing, or maintenance.

In some places the codes overlap. For example, the NEC has requirements for emergency lighting to support certain types of installations, but it does not have specific requirements for when general emergency, exit signs, or elevator power are required to be on emergency power.


The NEC also nfpa 110 2013 engineers about the overall system design criteria by presenting the different options as well as the minimum installation requirements. NFPA provides guidance on the performance, operation, and maintenance of emergency and standby power systems.

Knowing how to apply it properly requires an understanding of the terminology used in the standard nfpa 110 2013 well as its application. Level 1 is defined as "where failure of the equipment to perform could result in loss of human life or serious injuries. Level 2 is defined as "where failure of the EPSS to nfpa 110 2013 is less critical to human life and safety.

NFPASection 4. Included with the code are annexes that provide further guidance on the code's intent. While this information is not considered part of the code's language, it is useful to review to provide clarity of intent.

Level 1 Nfpa 110 2013 are clearly defined. Most of the requirements are simply good design practices. These nfpa 110 2013 sizing the unit for ambient temperature and elevation, installation per the NEC and manufacturer's requirements, and so on.

Others include oversizing the fuel storage tank Section 5.

These concerns mayor may not be constraints, depending on the facility. The list of equipment that, upon loss of power, could "create hazards" is extensive,which complicates this designation. This is further complicated by the need nfpa 110 2013 determine if the standard actually applies to the system.

NFPASection 1. This subtlety manifests by having similar nfpa 110 2013 in different jurisdictions having different designations.
