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 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 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 shall not be 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 I&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 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 intended to also mean IAS and HAS.
