CEI EN 50131-1

BILINGUAL

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.
