This European Standard specifies the requirements for External and Perimeter security systems (EPSS)- installed externally using specific or non-specific wired interconnections or wire-free interconnections. These requirements are not intended to apply to security system, e.g. intruder alarms, visual surveillance system (VSS), access control systems installed in buildings.
This standard specifies performance requirements for installed EPSS but does not include requirements for design, planning, installation, operation or maintenance.
These requirements also apply to EPSS sharing means of detection, triggering, interconnection, control, communication and power supplies with other applications. The operation of a EPSS shall not be adversely influenced by other applications.
Requirements are specified for EPSS components where the relevant environment is classified. This classification describes the environment in which a EPSS component may be expected to operate as designed.
Requirements for two environmental classes are specified for EPSS components. When the requirements of these two environmental classes are inadequate, due to the extreme conditions experienced in certain geographic locations, special national conditions are also specified in Annex A.
Interconnections and products used to combine both an I&HAS and EPSS systems, e.g. control and indicating equipment, should comply to both the IEC 62642 (EN 50131) and EPSS suite of standards. The failure of either system or a fault in either system should not be adversely affect the performance of the other.
