This part of the IEC 62642 is for combined passive infrared and microwave detectors installed
in buildings and provides for security Grades 1 to 4 (see IEC 62642-1), specific or nonspecific

This standard does not include requirements for detectors intended for use outdoors.
A detector fulfils all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this standard may be included in
the detector, providing they do not influence the correct operation of the mandatory functions.
This International Standard does not apply to system interconnections.
