Kevin Street 14 October 2004 Contents : Introduction (need for Emergency Lighting) Legal Requirements for Installations Exit Signs Luminaire Construction Green Alternative Impact of low mercury fluorescent lamps Emergency Fitting Types / Categories Testing Requirements Automatic Self Testing Systems Questions and Answers Contents The Need for Emergency Lighting : The Need for Emergency Lighting If artificial lighting is installed in any public access building Emergency Lighting is a mandatory requirement Provides light when the ordinary lighting fails due to a power cut and it is essential in safeguarding the occupants of a building in conjunction with other safety equipment Strict legal regulations governing Emergency Lighting - must be regularly tested which is the responsbility of the owner/occupier Legal Requirements : Legal Requirements INSTALLATIONS Designed,tested and installed to IS3217:1989 which are part of the building regulations EXIT SIGNS European Council directive no. 92/58/EEC (Running man type – implemented in 1995 - S.I. 132 ) LUMINAIRE CONSTRUCTION All Emergency Lighting luminaires must be constructed in compliance with EN60598-2-22 Legal Requirement Installation - Emergency Lighting Certificate : Legal Requirement Installation - Emergency Lighting Certificate All premises when handed over to the client must be certified to IS3217:1989 which consists of a certificate signed by the consulting engineer , the installer and commissioner . This standard primarily dictates types and positions of Emergency Fittings . Required Siting of Luminaires : Required Siting of Luminaires Required Siting of Luminaires : Required Siting of Luminaires Required Siting of Luminaires : Required Siting of Luminaires Required Siting of Luminaires : Required Siting of Luminaires Required Siting of Luminaires : Required Siting of Luminaires Required Siting of Luminaires : Required Siting of Luminaires Escape Routes - Requirements : Escape Routes - Requirements Minimum Lighting Levels : Escape Routes (previously called “defined escape routes”) Minimum Lighting Levels Photometrics/Spacing Tables : Photometrics/Spacing Tables Photometrics/Spacing Tables are used when designing an emergency lighting scheme/layout. Each emergency luminaire should have spacing tables. Open Areas - Requirements : Open Areas - Requirements Requirements to Minimise Risks : L N Unswitched supply Emergency lighting Normal lighting Non Maintained Emergency lighting must be activated by local final circuit failure Requirements to Minimise Risks Legal Requirements for Exit Signs : Legal Requirements for Exit Signs Illuminated signs must be used to indicate direction of escape routes Viewing Distance : Viewing Distance Internally illuminated - Max D = less than 200xH Externally illuminated - Max D = less than 100xH Legal Requirements for Luminaire Construction : Legal Requirements for Luminaire Construction Luminaires for Emergency Lighting EN 60.598.2.22 Certification : Recognised independent test house approves construction to the relevant European standard. Certified products ensures that products conform to all relevant EMC and LV Directives (CE). Certified inverters (to EN60924) conform to relevant safety and operating standards. Certification Fitting Types : Emergency lighting can be one of two system types: Self-Contained - each fitting has a board and battery Centrally supplied - each has a slave board, no battery Slave fittings are powered by CBS. Product types are available as slaves or self-contained Converted product-mains fitting converted to illuminate escape route Bulkhead - illuminates escape route Exit Sign-Illuminated directional sign Twinspot - illuminates high bay/open areas. Fitting Types Categories : Non-Maintained lamp only lights when mains fail. Maintained Lamp can light when mains is present and will light when mains fail. Sustained (Combined) There are two lamps, one only works when mains fail and the other only works when mains is present. Categories Slide 23: Green Alternative How can engineers of today and the future do their part ? Specify NiMh (less hazardous) as oppose to NiCd batteries. LED Emergency products now readily available - 100,000 hour lamp life -greatly reduced power consumption along with little or no heat dissipation. Slide 24: Impact of low mercury fluorescent lamps European Directive RoHS – Reduction of Hazadarous Substances (mandatory from July 2006) -The European lighting Companies federation advised of a level no greater than 5mg of mercury for fluorescent lamps in 1998 for environmental reasons due to the toxicity of this substance Slide 25: Impact of low mercury fluorescent lamps cont’d Why is this important ? It has implications for emergency (DC) operation . A variety of existing control gear are not designed to strike lamps with reduced mercury content . Problem manifests itself as mercury migration to one end of the lamp i.e. insufficient mercury is released and ‘pinking’ occurs followed by lamp failure . A solution to this is to ensure emergency control gear can run all new low mercury / amalgam lamps Routine System Testing - Safe Procedures : Do not switch off other essential services or equipment. Do not fully discharge a system if the building has to be re-occupied before re-charge is completed (Typically 24 hours). Do not test by removing fuses/MCB’s. This practice is not acceptably safe. Purpose designed test switches or systems should be utilised. Routine System Testing - Safe Procedures Testing Requirements IS3217: 1989 (pr EN 50172) : Testing Requirements IS3217: 1989 (pr EN 50172) Drawings of the emergency lighting installation shall be provided and retained on the premises. Annually a test certificate should be provided by the person responsible for the site A log book shall be kept on the premises & be available for inspection containing: Commissioning certificate Records of routine examination. Records Testing RequirementsIS3217:1989 : Testing RequirementsIS3217:1989 LEGAL COMMISSIONING AND TESTING REQUIREMENTS -Weekly mains presence(LED) and lamp check -3 Monthly discharge test for ½ Hour -Annual full rated discharge test for 3 hours (daily lamp check and monthly and annual discharge testing for BS5266 and PrEN50172) Slide 29: HOW CAN YOU BE SURE TESTING IS DONE - CORRECTLY AND ON TIME? AUTOMATIC TESTING Automatic Testing System type Self - Contained - stand-alone test facilities : Automatic Testing System type Self - Contained - stand-alone test facilities Initiation Automatic Timed Can be set to test alternate luminaires Indication local only Requires manual inspection Recording local only Requires manual recording Automatic Testing System type Self - Contained - Remote control panel : Automatic Testing System type Self - Contained - Remote control panel Initiation Automatic Timed or manually set Can be set to test alternate luminaires Indication Remote and local Remote inspection Recording From Remote Panel Manual or Automatic Printout FAULT-14 Automatic Testing - System Requirements Premises that may be occupied at time of duration test. : Automatic Testing - System Requirements Premises that may be occupied at time of duration test. If the building will not be empty for the full discharge test, Self contained emergency lights can be tested alternately i.e. grouped IEC 62034 (Draft) - Automatic Test systems for Emergency Lighting : IEC 62034 (Draft) - Automatic Test systems for Emergency Lighting Automatic testing of emergency lighting must be at least as effective as manual testing. Luminaire must be supplied from the battery. The tests must be performed at the correct intervals for the required times. Result of test must be reliably indicated. Test must be done at times of low risk.
