Non ATEX versions with MK6 detectors, Mounting Details
The non-ATEX version, 103 series flammable gas detector is typically fitted in areas that do not
require a flameproof gas detector approval. Typical applications would be boiler rooms, school
laboratories, commercial kitchens etc. Cabling should have a suitable level of protection for the
area into which the detector is fitted and be of a screened type such as CY style cable or FP200
style cable. Cable glands should provide a positive seal to limit ingress from dust and moisture.
