Introduction
This European Standard applies to Intrusion and Hold-up Alarm Systems. The standard is also intended to apply to Intruder Alarm Systems which include only intrusion detectors and to Hold-up Alarm Systems which include only hold-up devices.
This European Standard is a specification for Intrusion and Hold-up Alarm Systems (l&HAS) installed in buildings, it includes four security grades and four environmental classes.
The purpose of an l&HAS is to enhance the security of the supervised premises. To maximise its effectiveness an l&HAS should be integrated with appropriate physical security devices and procedures. This is particularly important to higher grade l&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 l&HAS refer to basic minimum requirements and the designers of such installed l&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 l&HAS.
Recommendations for design, planning, operation, installation and maintenance are given in Application Guidelines CLC/TS 50131-7.
This standard is not intended to be used for testing individual l&HAS components. Requirements for testing individual l&HAS components are given in the relevant component standards.
l&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.

1 Scope
This European Standard specifies the requirements for Intrusion and Hold-up Alarm Systems installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. These requirements also apply to the components of an l&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 l&HAS.
This standard specifies performance requirements for installed l&HAS but does not include requirements for design, planning, installation, operation or maintenance.
These requirements also apply to l&HAS sharing means of detection, triggering, interconnection, control, communication and power supplies with other applications. The operation of an l&HAS shall not be adversely influenced by other applications.
Requirements are specified for l&HAS components where the relevant environment is classified. This classification describes the environment in which an l&HAS component may be expected to operate 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 l&HAS components are described in Clause 7.
The requirements of this European Standard also apply to IAS and HAS when these systems are installed independently.
When an l&HAS does not include functions relating to the detection of intruders, the requirements relating to intrusion detection do not apply.
When an l&HAS does not include functions relating to hold-up, the requirements relating to hold-up do not apply.
NOTE Unless otherwise stated the abbreviation l&HAS is intended to also mean IAS and HAS.
