Alarm systems - Alarm transmission systems and equipment - Part 1-2: Requirements for systems using dedicated alarm paths
Requirements for alarm transmission systems using dedicated alarm transmission paths.
This European Standard, a part of the EN 50136 series, specifies the requirements for alarm transmission systems utilizing dedicated alarm transmission paths which are additional to those specified in EN 50136-1-1.
The alarm transmission system may utilize wired links (e.g. d.c. or a modulated signal over a twisted pair cable), voice grade signalling links or data links, and may include multiplexers or message processors.
This standard is also applicable to alarm transmission systems in which signalling links are shared with other services. Such services include normal subscriber telephone lines from the supervised premises to the local exchange, cable TV or power distribution networks.
