BS EN 50131-1:2006+Amendment 1:2009 Alarm systems. Intrusion and hold-up systems. System requirements
BS EN 50131-1 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.
BS EN 50131-1 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 purpose of I&HAS is to enhance the security of the supervised premises. To maximise its effectiveness I&HAS should be integrated with appropriate physical security devices and procedures. This is particularly important to higher grade I&HAS.
I&HAS and their components are graded to provide the level of security required. The security grades take into account the risk level which depends on the type of premises, the value of the contents, and the typical intruder or robber expected.
BS EN 50131-1 will assist insurers, intruder alarm companies, customers and the police in achieving a complete and accurate specification of the supervision required in particular premises.
BS EN 50131-1 does not include requirements for exterior I&HAS and only applies to systems that 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. This standard is not intended to be used for testing individual I&HAS components. Requirements for testing individual I&HAS components are given in the relevant component standards.
