3.1.4 Replacing a Detector or Using it at another
Measuring Point
Detectors which are used in non-hazardous areas are not subject to
the supervision and maintenance of Ex-protection experts; there-
fore, it is not guaranteed that, for example, for repair or assembly,
the necessary care is taken which is required for the detectors in Ex-
areas. The Ex-protection safety is therefore no longer guaranteed.
The same applies to the intrinsic safety of detectors. Therefore:
• Detectors that are used in the non-Ex area may not be used in
an Ex area.
• Intrinsically safe detectors, whose intrinsically safe signals are
connected to non-intrinsically safe circuits must not be con-
nected to intrinsically safe circuits any more.
