This Technical Specification specifies the requirements, testing procedures security and environmental
performance criteria for control and indicating equipment (CIE) intended for use in intrusion alarm
system (IAS) and hold-up alarm systems (HAS) installed in buildings.
This Technical Specification specifies the requirements for CIE installed in buildings using specific or
non-specific wired interconnections or wire-free interconnections. These requirements also apply to the
components of a CIE which are normally mounted on the external structure of a building. (EXAMPLE:
Ancillary control equipment).
This Technical Specification specifies performance requirements for CIE but does not include
requirements for design, planning, installation, operation or maintenance.
These requirements apply also to CIE sharing means of detection, interconnection, control,
communication and power supplies with other applications.
Requirements are specified for CIE components where the relevant environment is classified. This
classification describes the environment in which the CIE 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 of EN 50131-1. General environmental requirements for CIE components are described in
Clause 7.
NOTE In this Technical Specification reference to the term “I&HAS” is used throughout the specification. The term is intended
to include IAS and HAS when such systems are installed separately.
