Over deze norm
This European Standard specifies the requirements for the performance, reliability and security characteristics of alarm transmission systems. It covers the general requirements for connections providing signalling between an alarm system at a supervised premises and annunciation equipment at an alarm receiving centre. EN 50136-1 applies for transmission of all types of alarm messages such as fire, intrusion, access control, social alarm, etc. Different types of alarm system may in addition to alarm messages also send other types of messages, e.g. fault messages and status messages. Also these messages are considered part of alarm transmission. The term alarm is used in this broad sense throughout the document. Additional requirements for the connection of specific types of alarm systems are given in the relevant European Standards.
