Alarm systems - Alarm transmission systems and equipment - Part 1-3: Requirements for systems with digital communicators using the public switched telephone network

Scope

This standard specifies the requirements for digital communicator systems utilising the Public Switched Telephone Network which are in addition to those specified in EN 50136-1-1. It covers switched connections providing event driven signaling between an alarm system and a remote centre. The information will be transmitted using digitized signals to automatic receiving centre transceivers at remote centres. A facility may be included to provide an audio channel. The remote centre will normally be an alarm receiving centre but may be a remote centre with onward transmission using an alarm transmission system meeting the requirements of EN 50136-1-2
