Over deze norm
This European Standard specifies the requirements for Intrusion and Hold-up Alarm Systems installed in buildings using specific or none specific wired interconnections or wire-free interconnections. These requirements also apply to the components of a I&HAS installed in a building which are normally mounted on the external structure of a building. EXAMPLE: 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 operation 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 the I&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 I&HAS components are described in Clause 7.
