Over deze norm
Specifies the requirements for equipment used in alarm transmission systems utilising dedicated alarm transmission paths which are additional to those specified in EN 50136-2-1. The alarm transmission system may utilise wired links (e.g. d.c. or a modulated signal over a twisted pair cable), voice grade signalling links or date links and may include multiplexers or message processors. The standard is also applicable to alarm transmission systems in which signalling links are shared with other services. Such services include normal subscriber telephone line from the supervised premises to the local exchange, cable TV or power distribution networks, but is equally applicable to other systems. The object of this standard is to specify the performance characteristics of equipment used in alarm transmission systems using dedicated alarm transmission paths to ensure their suitability for use with and compatibility with different types of alarm systems.
