What is this standard about?
This standard is Part 1 in a series of European standards and technical specifications on intrusion and hold-up alarm system (I&HAS).
It sets out system requirements for I&HAS installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. It also applies to Intruder Alarm Systems which include only intrusion detectors and to Hold-up Alarm Systems which include only hold-up devices.
Who is this standard for?
Purchasers and specifiers of I&HAS in any sector as well as manufacturers, consultants, designers, installers and maintainers of I&HAS (Electronic security sector).
The standard will also be of interest to insurers, I&HAS customers and the police.
Why should you use this standard?
This standard will help users gain a complete and accurate specification of the supervision required in any particular premises, depending on the nature of the premises, the value of the contents, the degree of risk of intrusion, the threat to personnel and other factors that might influence the choice of grade and content of an I&HAS.
A key feature is that the standard describes four grades of alarm system:
- Grade 1: Low risk. An intruder or robber is expected to have little knowledge of I&HAS and be restricted to a limited range of easily available tools.
- Grade 2: Low to medium risk. An intruder or robber is expected to have a limited knowledge of I&HAS and the use of a general range of tools and portable instruments (e.g. a multi-meter).
- Grade 3: Medium to high risk. An intruder or robber is expected to be conversant with I&HAS and have a comprehensive range of tools and portable electronic equipment.
- Grade 4: High risk. To be used when security takes precedence over all other factors. An intruder or robber is expected to have the ability or resource to plan an intrusion or robbery in detail and have a full range of equipment including means of substitution of components in an I&HAS.
All alarm components must meet the standard’s requirements and all components meeting the requirements are assigned a security grade. The overall grade of an alarm system cannot be higher than the grade of the lowest graded component within the system. This enables manufacturers, installers, purchasers and procurers to ensure that an alarm system is fit for purpose and meets the risk assessment criteria.
NOTE: Recommendations for design, planning, operation, installation and maintenance are given in Application Guidelines CLC/TS 50131-7.
