C&K SWITCHES FOR SMOKE DETECTORS SO2 QUALIFICATION www.ck-components.com SO2 QUALIFICATION According to European standards, all smoke detectors need to be compliant with IEC 60068-2-42:2003 which is the sulphur dioxide test for contacts and connections. It can be tested either at the system level or switch level. This protocol calls for a rigorous 4 day test with a temperature of 25C, SO2 concentration 25x10-6 and relative humidity at 93% for compliance with European standards. Since this qualification can also be given at the switch level, C&K has qualified some of its products to the IEC 60068-2-42:2003 standards so they can be integrated in any system going into a smoke detector in Europe. The part numbers listed on the next page are compliant with the SO2 qualification at the switch level. C&K offers additional products that can be integrated in smoke detectors and are compliant with these regulations when the system in which they are installed is sealed against SO2. ADDITIONAL INFORMATION Standard part number features are available on our website. C&K recommends contacting your local sales representative to confirm product availability. Technical specifications are available on request, on our website under the "ask a specialist" item or through your sales representative.
