C&K SWITCHES FOR
SMOKE DETECTORS
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 25°C, 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.
Standard part number features are available on our website. C&K rec-
ommends 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.
