1 Scope
This standard specifies the general requirements for detectors for use in intruder alarm systems installed in buildings.
Additional requirements for each type of detector are given in the specific standard for that detector.
This standard and the standards for specific types of detector give the minimum requirements for the performance, installation and testing of detectors. Additional features may be incorporated provided that the performance and reliability of the detector are not adversely affected.
For detectors with enhanced performance, additional or more severe test procedures are specified.
This standard also defines those characteristics of the detector which are to be specified by the supplier, including operational requirements.
This standard shall be used in conjunction with the following IEC publications:
IEC 839-1-1: 1988 Alarm systems, Part 1: General requirements. Section One - General.
IEC 839-1-2: 1987 Alarm systems, Part 1: General requirements. Section Two - Power units
IEC 839-1-3: 1987 Alarm systems, Part 1: General requirements. Section Three - Environmental testing.
2 Object
The object of this standard is to specify those requirements of detectors which ensure that they are compatible with other parts of the intruder alarm systems, with the aim of providing satisfactory performance in the detection of intruders whilst minimizing false operation due to environmental effects.
