ALARM SYSTEMS
Part 2: Requirements for intruder alarm systems
Section Two — Requirements for detectors — General
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 incorpo-
rated 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:
839-1-1: Alarm systems, Part I : General requirements. Section One – General. (Under consideration.)
839-1-2 (1987): Section Two – Power units, test methods and performance criteria.
839-1-3 (1987): Section Three – Environmental testing.
839-2-1: Pa rt 2: Requirements for intruder alarm systems. Section One – General. (Under consideration.)
2. Object
The object of this standard is to specify those requirements of detectors which ensure that they
are compatible with other pa rts of the intruder alarm systems, with the aim of providing satis-
factory performance in the detection of intruders whilst minimizing false operation due to
environmental effects.
3. Reference documents
IEC Publications:
68: Basic environmental testing procedures.
68-1 (1982): Part 1: General and guidance.

4. Definitions
For the purpose of this standard the following definitions apply:
4.1 Detector
A device designed to generate an alarm condition in response to intrusion or attempted
intrusion, or to deliberate action by the user.
4.2 Sensor
That part of a detector which senses a change in condition which could be caused by intrusion
or attempted intrusion.
4.3 Processor
A device which processes the output from one or more sensors to determine whether an alarm
condition should be generated.
General considerations
5.
A detector may be a single integrated unit or may consist of one or more sensors connected to a
signal processing unit.
The detection function includes all those parts of a system which determine whether or not an
alarm condition is present.
6. Requirements
6.1 Functional
6.1.1 Performance
The detector shall perform as specified under the range of supply voltage and environmental
conditions given in the specification.
When the detector generates an alarm condition, this shall be maintained for at least 1 s.
The environmental conditions apply only to the immediate vicinity of the detector when
installed in a system. The detector shall meet its operational requirement within 60 s after
power on.
6.1.2 Range adjustment
A control may be provided for adjusting the range of the detector.
If such a control is fitted and is normally accessible to the installation engineer, the adjustment
shall not exceed a ratio of three to one between the maximum range and the minimum
range.
The adjustment shall have calibrated positions which shall include the maximum and the
minimum selectable values.

interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

INTRODUCTION
The IEC 60811 series specifies the test methods to be used for testing non-metallic materials
of all types of cables. These test methods are intended to be referenced in standards for
cable construction and for cable materials.
NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables.
NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over
many years principally for the materials in all energy cables. They have also been widely accepted and used for
other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore
applications.
