Title Alarm systems - Alarm transmission systems and equipment - Part 2-2: Requirements for equipment used in systems using dedicated alarm paths
Project Number 4982
Abstract/Scope This standard specifies in addition to the requirements specified in EN 50136-2-1, the requirements for equipment used in alarm transmission systems utilising dedicated alarm transmission paths. The alarm transmission system may utilise wired links (e.g. d.c. or a modulated signal over a twisted pair cable), voice grade signaling links or data links and may include multiplexers or message processors. The standard is also applicable to alarm transmission systems in which signaling 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
