4 Concepts by subject area
This glossary’s source standards and included concepts are given in Tables 1 to 6, classified by following
subject areas:
1) common items (Table 1);
2) intrusion and hold-up systems (Table 2);
3) CCTV surveillance systems (Table 3);
4) access control systems (Table 4);
5) social alarm systems (Table 5);
6) alarm transmission systems (Table 6).
For each subject area the concepts are numbered with the objective of presenting contextually related
definitions close to each other.
Each concept is presented by
• concept number,
• term in English,
• definition in English,
• reference to publication, by means of publication number and clause number.
If the definitions in two or more publications are identical, then references are underlined in Ref.
publication column. Underlined and bolded reference indicates from where the definition of term have
been taken to this part of the glossary. Reference without underlining or bolding indicates that definitions
in glossary and reference standard are not identical.
