Publication date:   Jan 1, 1999

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
