Overview

IEC 62642-1:2010 - “Alarm systems - Intrusion and hold‑up systems - Part 1: System requirements” defines the system‑level requirements for intrusion and hold‑up alarm systems (I&HAS) installed in buildings. The standard covers systems using specific or non‑specific wired interconnections as well as wire‑free (wireless) interconnections, and applies to I&HAS components normally mounted on the building exterior (for example ancillary control equipment and warning devices). IEC 62642-1 is the first part of the IEC 62642 series and aligns with EN 50131‑1 (2006) and its Amendment 1 (2009).

Key topics and technical requirements

The standard sets out functional, environmental and reliability requirements for I&HAS, including:

• System functions and components: definition of I&HAS architecture, detector types, control panels, warning devices and ancillary equipment.
• Functional requirements: detection of intruders, hold‑up triggering, tamper detection, fault recognition and masking.
• Operation and access control: access levels, authorization methods, setting/unsetting, inhibit/isolate and testing procedures.
• Processing and messaging: which signals/messages must be generated and how intruder, hold‑up, tamper and fault events are processed.
• Indication and notification: local and remote indication requirements, notification pathways and alarm transmission performance criteria (informative annex).
• Tamper security and monitoring: tamper protection, substitution monitoring and timing/verification requirements.
• Interconnections and communications: availability, monitoring, verification intervals and security of communications for wired and wireless links.
• Power supply and reliability: primary and alternative power supply requirements, minimum backup durations and recharge expectations.
• Environmental and safety: environmental classification (Indoor/Outdoor classes I–IV), electromagnetic compatibility (EMC) and electrical safety.
• Documentation and marking: required system and component documentation, event recording and identification.

Applications and who uses it

IEC 62642-1 is used by:

• System designers and manufacturers - to design compliant I&HAS components and control systems.
• Installers and integrators - for correct installation, interconnection and commissioning of alarms.
• Security consultants and specifiers - to define performance and grading requirements in bids and specifications.
• Facility managers and end users - to understand operational behaviour, testing and maintenance obligations.
• Certification and conformity assessors - to evaluate system compliance with system‑level requirements.

Practical applications include designing building alarm systems, selecting compliant components, specifying alarm transmission performance, and producing installation and handover documentation.

INTRODUCTION
This standard is part of the IEC 62642 series of International Standards and Technical
Specifications “Alarm systems – Intrusion and hold-up systems”, written to include the following
parts:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors

Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices
This International Standard applies to Intrusion and Hold-up Alarm Systems (I&HAS). The
standard is also intended to apply to Intruder Alarm Systems (IAS) which include only intrusion
detectors and to Hold-up Alarm Systems (HAS) which include only hold-up devices.
This International Standard is a specification for Intrusion and Hold-up Alarm Systems installed
in buildings, it includes four security grades and four environmental classes.
The purpose of an I&HAS is to enhance the security of the supervised premises. To maximise
its effectiveness an I&HAS should be integrated with appropriate physical security devices and
procedures. This is particularly important to higher grade I&HAS.
This standard is intended to assist insurers, intruder alarm companies, customers and the
police in achieving a complete and accurate specification of the supervision required in
particular premises, but it does not specify the type of technology, the extent or degree of
detection, nor does it necessarily cover all of the requirements for a particular installation.
All references to the requirements for I&HAS refer to basic minimum requirements and the
designers of such installed I&HAS should take into account the nature of the premises, the
value of the contents, the degree of risk of intrusion, the threat to personnel and any other
factors which may influence the choice of grade and content of an I&HAS.
Recommendations for design, planning, operation, installation and maintenance are given in
Application Guidelines EN/TS 50131-7.
This standard is not intended to be used for testing individual I&HAS components.
Requirements for testing individual I&HAS components are given in the relevant component
standards.
– 8 – 62642-1 © IEC:2010
I&HAS and components thereof are graded to provide the level of security required. The
security grades take into account the risk level which depends on the type of premises, the
value of the contents, and the typical intruder or robber expected.

Part 1: System requirements
1 Scope
This part of IEC 62642 specifies the requirements for Intrusion and Hold-up Alarm Systems
(I&HAS) installed in buildings using specific or non-specific wired interconnections or wire-free
interconnections. These requirements also apply to the components of an I&HAS installed in a
building which are normally mounted on the external structure of a building e.g. ancillary
control equipment or warning devices. The standard does not include requirements for exterior
I&HAS.
This International Standard specifies performance requirements for installed I&HAS but does
not include requirements for design, planning, installation, operation or maintenance.
These requirements also apply to I&HAS sharing means of detection, triggering,
interconnection, control, communication and power supplies with other applications. The
functioning of an I&HAS is not adversely influenced by other applications.
Requirements are specified for I&HAS components where the relevant environment is
classified. This classification describes the environment in which an I&HAS component may be
expected to function as designed. When the requirements of the four environmental classes
are inadequate, due to the extreme conditions experienced in certain geographic locations,
special national conditions are given in Annex A. General environmental requirements for
7.
I&HAS components are described in Clause
The requirements of this standard also apply to IAS and HAS when these systems are installed
independently.
When an I&HAS does not include functions relating to the detection of intruders, the
requirements relating to intrusion detection do not apply.
When an I&HAS does not include functions relating to hold-up, the requirements relating to
hold-up do not apply.
NOTE Unless otherwise stated, the abbreviation I&HAS is also intended to mean IAS and HAS.

3.2 Abbreviations
For the purposes of this document, the following abbreviations are used:
ARC – alarm receiving centre
ACE – ancillary control equipment
ATS – alarm transmission system
CIE – control and indicating equipment
HAS – hold-up alarm system(s)
IAS – intruder alarm system(s)
I&HAS – intrusion and hold-up alarm system(s)

SPT – supervised premises transceiver
4 System functions
I&HAS shall include, as appropriate to the configuration of the I&HAS, the functions specified in
this standard for the detection of intruders and/or triggering, processing of information,
notification of alarms and the means to operate an I&HAS.
Functions additional to the mandatory functions specified in this standard may be included in
I&HAS providing they do not influence the correct operation of the mandatory functions.
5 System components
I&HAS components shall be classified according to their environmental capability and graded
according to their performance.
I&HAS components shall be compatible within an I&HAS and selected according to the system
grade and appropriate environmental classification.
Components of other applications may be combined or integrated with an I&HAS, providing the
performance of the I&HAS components is not adversely influenced.

– 18 – 62642-1 © IEC:2010
6 Security grading
I&HAS shall be given a security grading which will determine its performance. The grading shall
be one of four grades with grade 1 being the lowest grade and grade 4 the highest. The grade
of an I&HAS shall be that of the lowest graded component.
When an I&HAS is divided into clearly defined sub-systems, an I&HAS may include
components of differing grades within each sub-system. The grade of a subsystem shall be
that of the lowest graded component within it.
Components shared by more than one sub-system shall have a grade equal to that of the
highest sub-system grade (e.g. control and indicating equipment/alarm transmission
systems/warning devices/power supplies).
If a function is provided that is optional for a particular grade and a claim of compliance is
made, it shall meet the applicable requirements for the grade for which compliance is claimed
(if any are given). If there are no specifications for the grade in question, the requirements for
any higher grade (as identified by the manufacturer) shall apply.
NOTE 1 For the guidance of specifiers and those responsible for the security of premises, the following grades are
given:
Grade 1: Low risk
An intruder or robber is expected to have little knowledge of I&HAS and be restricted to a limited range
of easily available tools.
Grade 2: Low to medium risk
An intruder or robber is expected to have a limited knowledge of I&HAS and the use of a general range
of tools and portable instruments (e.g. a multi-meter).
Grade 3: Medium to high risk
An intruder or robber is expected to be conversant with I&HAS and have a comprehensive range of tools
and portable electronic equipment.
Grade 4: High risk
To be used when security takes precedence over all other factors. An intruder or robber is expected to
have the ability or resource to plan an intrusion or robbery in detail and have a full range of equipment
including means of substitution of components in an I&HAS.
NOTE 2 In the all grades, the term “Intruder” is intended to embrace other types of threat (e.g. robbery or the
threat of physical violence, which might influence the design of an I&HAS).
7 Environmental classification
7.1 General
Components shall be suitable for use in one of the following environmental classes.
Environmental test requirements for I&HAS components are given in the individual component
standards. IEC 62599-1 describes the environmental test methods to be applied to I&HAS
components.
NOTE 1 Classes I, II, III and IV are progressively more severe and therefore Class IV components may, for
example, be used in Class III I&HAS.
I&HAS components shall operate correctly when exposed to environmental influences specified
in 7.2, 7.3, 7.4 and 7.5. For each class, typical information is given below.
NOTE 2 Annex A includes special national conditions for specified countries.
NOTE 3 The environmental conditions described in Clause 7 are those in which an I&HAS is expected to perform
correctly, they are not necessarily the conditions to be used during the testing of I&HAS components.

62642-1 © IEC:2010 – 19 –
7.2 Environmental Class I – Indoor
Environmental influences normally experienced indoors when the temperature is well
maintained (e.g. in a residential or commercial property).
NOTE Temperatures may be expected to vary between +5 °C and +40 °C with average relative humidity of
approximately 75 % non-condensing.
7.3 Environmental Class II – Indoor – General
Environmental influences normally experienced indoors when the temperature is not well
maintained (e.g. in corridors, halls or staircases and where condensation can occur on
windows and in unheated storage areas or warehouses where heating is intermittent).
NOTE Temperatures may be expected to vary between –10 °C and +40 °C with average relative humidity of
approximately 75 % non-condensing.
7.4 Environmental Class III – Outdoor – Sheltered or indoor extreme conditions
Environmental influences normally experienced out of doors when I&HAS components are not
fully exposed to the weather or indoors where environmental conditions are extreme.
NOTE Temperatures may be expected to vary between –25 °C and +50 °C with average relative humidity of
approximately 75 % non-condensing. For 30 days per year, relative humidity can be expected to vary between 85 %
and 95 % non-condensing.
7.5 Environmental Class IV – Outdoor – General
Environmental influences normally experienced out of doors when I&HAS components are fully
exposed to the weather.
NOTE Temperatures may be expected to vary between –25 °C and +60 °C with average relative humidity of
approximately 75 % non-condensing. For 30 days per year, relative humidity can be expected to vary between 85 %
and 95 % non-condensing.

INTRODUCTION
This standard is part of the IEC 62642 series of International Standards and Technical
Specifications “Alarm systems – Intrusion and hold-up systems”, written to include the following
parts:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / Microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / Ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices
This International Standard applies to Intrusion and Hold-up Alarm Systems (I&HAS). The
standard is also intended to apply to Intruder Alarm Systems (IAS) which include only intrusion
detectors and to Hold-up Alarm Systems (HAS) which include only hold-up devices.
This International Standard is a specification for Intrusion and Hold-up Alarm Systems installed
in buildings, it includes four security grades and four environmental classes.
The purpose of an I&HAS is to enhance the security of the supervised premises. To maximise
its effectiveness an I&HAS should be integrated with appropriate physical security devices and
procedures. This is particularly important to higher grade I&HAS.
This standard is intended to assist insurers, intruder alarm companies, customers and the
police in achieving a complete and accurate specification of the supervision required in
particular premises, but it does not specify the type of technology, the extent or degree of
detection, nor does it necessarily cover all of the requirements for a particular installation.
All references to the requirements for I&HAS refer to basic minimum requirements and the
designers of such installed I&HAS should take into account the nature of the premises, the
value of the contents, the degree of risk of intrusion, the threat to personnel and any other
factors which may influence the choice of grade and content of an I&HAS.
Recommendations for design, planning, operation, installation and maintenance are given in
Application Guidelines EN/TS 50131-7.
This standard is not intended to be used for testing individual I&HAS components.
Requirements for testing individual I&HAS components are given in the relevant component
standards.
– 8 – 62642-1 © IEC:2010
I&HAS and components thereof are graded to provide the level of security required. The
security grades take into account the risk level which depends on the type of premises, the
value of the contents, and the typical intruder or robber expected.

ALARM SYSTEMS –
INTRUSION AND HOLD-UP SYSTEMS –

Part 1: System requirements
1 Scope
This part of IEC 62642 specifies the requirements for Intrusion and Hold-up Alarm Systems
(I&HAS) installed in buildings using specific or non-specific wired interconnections or wire-free
interconnections. These requirements also apply to the components of an I&HAS installed in a
building which are normally mounted on the external structure of a building e.g. ancillary
control equipment or warning devices. The standard does not include requirements for exterior
I&HAS.
This International Standard specifies performance requirements for installed I&HAS but does
not include requirements for design, planning, installation, operation or maintenance.
These requirements also apply to I&HAS sharing means of detection, triggering,
interconnection, control, communication and power supplies with other applications. The
functioning of an I&HAS is not adversely influenced by other applications.
Requirements are specified for I&HAS components where the relevant environment is
classified. This classification describes the environment in which an I&HAS component may be
expected to function as designed. When the requirements of the four environmental classes
are inadequate, due to the extreme conditions experienced in certain geographic locations,
special national conditions are given in Annex A. General environmental requirements for
7.
I&HAS components are described in Clause
The requirements of this standard also apply to IAS and HAS when these systems are installed
independently.
When an I&HAS does not include functions relating to the detection of intruders, the
requirements relating to intrusion detection do not apply.
When an I&HAS does not include functions relating to hold-up, the requirements relating to
hold-up do not apply.
NOTE Unless otherwise stated, the abbreviation I&HAS is also intended to mean IAS and HAS.

4 System functions
I&HAS shall include, as appropriate to the configuration of the I&HAS, the functions specified in
this standard for the detection of intruders and/or triggering, processing of information,
notification of alarms and the means to operate an I&HAS.
Functions additional to the mandatory functions specified in this standard may be included in
I&HAS providing they do not influence the correct operation of the mandatory functions.
5 System components
I&HAS components shall be classified according to their environmental capability and graded
according to their performance.
I&HAS components shall be compatible within an I&HAS and selected according to the system
grade and appropriate environmental classification.
Components of other applications may be combined or integrated with an I&HAS, providing the
performance of the I&HAS components is not adversely influenced.

– 18 – 62642-1 © IEC:2010
6 Security grading
I&HAS shall be given a security grading which will determine its performance. The grading shall
be one of four grades with grade 1 being the lowest grade and grade 4 the highest. The grade
of an I&HAS shall be that of the lowest graded component.
When an I&HAS is divided into clearly defined sub-systems, an I&HAS may include
components of differing grades within each sub-system. The grade of a subsystem shall be
that of the lowest graded component within it.
Components shared by more than one sub-system shall have a grade equal to that of the
highest sub-system grade (e.g. control and indicating equipment/alarm transmission
systems/warning devices/power supplies).
If a function is provided that is optional for a particular grade and a claim of compliance is
made, it shall meet the applicable requirements for the grade for which compliance is claimed
(if any are given). If there are no specifications for the grade in question, the requirements for
any higher grade (as identified by the manufacturer) shall apply.
NOTE 1 For the guidance of specifiers and those responsible for the security of premises, the following grades are
given:
Grade 1: Low risk
An intruder or robber is expected to have little knowledge of I&HAS and be restricted to a limited range
of easily available tools.
Grade 2: Low to
