Hi All, I'm trying to resolve an issue with our emergency lighting as part of a general review of fire risk assessments. I understnd a number of tests are required but don't have the correct reference. We currently check the lights in house on a monthly basis - (on/off) to confrim they are functioning. They are checked by an fire protection engineering firm every 6 months. I recall reading some years ago they should have a prolonged test to check battery life but i can't remember the details. As a site we have had a poor electrcial supply (rural) and we could guarantee at least 2 occasion a year where power failed for 3 hours+. While this is great for running down emergency batteries its lousy for the business and an updated supply now means we can't rely on this and its not best practice anyway. We also have a situation where some of the test switches diable the main lights when engaged while others do not. This means we can't do an extended test while the buildings are occupied. I like to know if otehrs have experience of this. Do we get the lighting circuits changed to allow a prolonged test or are there other options? Regards Jon

Hi, I think that for a battery powered central power supply you need BS EN 50172 (possibly it supersedes BS 5266 not sure) and for batteries for self contained systems its BS EN 60598. Cheers Steve

BS EN 50172:2004 is dual numbered as BS5266-8:2004. Thus it is part of BS5266, I nver said it was a single standard! ;-)) BS 5266 has MANY parts! BS EN 60598 is a product standard for luminaires. The end user has no control over this what so ever, this standard concerns the OEM! It covers how the liminaire is to be designed, constructed and tested, the instructions for its seafe use and maintenance etc. The OP IIRC is concerend with compliance with the RRFSO? HTH
