This Part of IEC 62820<\/span> <\/span> specifies the technical requirements for the composition, functions, performance, and test methods of general building intercom systems.<\/p>\n

This part is applicable to the general intercom systems for building entry in residential or commercial buildings.<\/p>\n

Door-Entry-System (DES) is a simple kind of convenient Building-Intercom-System (BIS) mainly for user\u2019s comfort. This document has classified the general building intercom systems into two grades in Part 1-1. Grade 1 adopts lower requirements to cover DES not used for relevant security applications while grade 2 adopts higher requirements for building intercom systems for security applications. Each grade may adopt different functional and performance requirements, test methods and normative references.<\/p>\n

\n
\n NOTE\n <\/div>\n

The different requirements between grade 1 and grade 2 are summarized in Table C.1<\/span>.<\/p>\n<\/div>\n
