Mission critical standby systems provide power to critical operations power systems (COPS) for public safety, national security, or business continuity reasons. Electrical equipment and wiring that serve these designated critical operation areas must remain operational during a natural or man-made disaster. The National Electrical Code (NEC) describes the engineering practices for mission critical facilities, which go beyond the requirements for emergency and legally required standby systems. In addition to specific code requirements, design engineers as well as authorities having jurisdiction must know the requirements for the installation, operation, control, and maintenance of standby power for mission critical facilities.

  • 8. Take a closer look at what it means for afacility to be mission critical and thecriteria for designating a facility asmission critical Types of Mission Critical Facilities Standards and Codes Utilized forDesigning Mission Critical Facilities Reliability requirements of missioncritical facility standby power systems
  • 9. Definition of Mission Critical“A mission critical system is a system that is essentialto the survival of a business or organization. When amission critical system fails or is interrupted,operations are significantly impacted.”• Availability – System must function when required (24x7)• Reliability – System must not fail. If a failure occurs the systemmust respond and recover quickly.• Security – System must provide protection against an attack,either human or naturally caused
  • 10. Private - Business Continuity• Business Enterprise Data Centers• Financial Data Centers and Trading• Internet CompaniesPublic Safety• Emergency Call Centers• Police & Fire Stations• Hospitals• National SecurityTypes of Mission Critical Facilities
  • 11. Facilities where the levels ofavailability and reliability aredictated by the business case• Acceptable Level of Risk• Downtime for Maintenance• Required Degree Redundancy• Protection Against FailuresPrivate – Business Continuity
  • 12. - ANSI TIA-942 Standard- Uptime Institute GuidelinesPrivate – Business ContinuityTier classifications have been establishedas a guide to assist in designing a topologythat will delivery the required level ofavailability and reliability• Tier 1 - Basic• Tier 2 - Redundant Components• Tier 3 – Concurrently Maintainable• Tier 4 - Fault Tolerant
  • 13. Tier 1 – Basic• Susceptible to disruptions fromplanned and unplanned activity• Capacity design is “Need” (N) only,no redundant components• Infrastructure shut down requiredfor preventive maintenance andrepair work.• Annual downtime 28.8 hoursUPTIME INSTITUTE
  • 14. Tier 2 – Redundant Components• Less susceptible to disruptionsfrom planned and unplannedactivity• Capacity design is “Need plusOne” (N+1)• Single-threaded distribution path• Maintenance of critical power pathand other parts of siteinfrastructure require a processingshutdown• Annual downtime 22.0 hoursUPTIME INSTITUTE
  • 15. Tier 3 – Concurrent Maintenance• Allows for planned infrastructureactivity (maintenance, repair,expansion) without disrupting• Capacity design is “Need plusOne” (N+1)• Dual -threaded distribution path• Can carry the load on one pathwhile performing maintenance ortesting on the other path.• Errors in operation or failures offacility infrastructure componentscan still cause a disruption.• Annual downtime 1.6 hours UPTIME INSTITUTE
  • 16. Tier 4 – Fault Tolerant• High reliability, availability andserviceability.• Allows for planned activity withoutdisruption to the critical load• Capacity design is “System +System” (2N)• Dual -threaded distribution path• System can sustain one worst-case unplanned failure with noimpact on the critical load.UPTIME INSTITUTE

  • 36. Wiring Requirements (cont.)Special Note: UL Public Notice Sept. 12, 2012UL and ULC announced important changes to certification programs (release12PN-51). As a result, manufacturers are no longer authorized to place the ULor ULC mark on these fire rated cables.A interim certification program was re-established in December 2012 to allowmanufacturers to achieve certification under an interim program. So far, onlytwo manufacturers have obtained listing. UL reports that more are expected inthe near future.View UL Website for additional informationhttp://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/showpage.html?name=FHJR.GuideInfo&ccnshorttitle=Fire-resistive+Cable&objid=1074292591&cfgid=1073741824&version=versionless&parent_id=1073986610&sequence=1
