Alarm systems - Alarm transmission systems and equipment -- Part 1-2: Requirements for systems using dedicated alarm paths
This standard specifies the requirements for alarm transmission systems utilising dedicated alarm transmission paths which are additional to those specified in EN 50136-1-1. The alarm transmission system may utilise wired links (e.g. DC 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
