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
I&HAS components are described in Clause 7.
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.
