This part of IEC 62820<\/span> <\/span> specifies the technical requirements for the composition, functions, performance and test methods of building intercom systems using the internet protocol (IP), and it is a supplement to IEC 62820\u20111\u20111<\/span> <\/span>.<\/p>\n

This document is applicable to the IP building intercom systems for both residential and commercial buildings.<\/p>\n
