Information about this document

Where the alarm transmission system (ATS) performance, in terms of speed and information security, are not considered a high priority, it might still be important to notify an alarm receiving centre (ARC) of the failure of an ATS in a suitable time that allows a response to the failure be requested, ensuring a level of mitigation against any impact of a malicious attack to an ATS. To this end, additional ATS categories, SP3+ and DP2+, are included, with improved reporting times, for use in systems where there is a perceived risk or history of malicious attack.

The guidance in this Published Document is presented in roman (i.e. upright) type. Any recommendations are expressed in sentences in which the principal auxiliary verb is “should”.

1 Scope

This Published Document provides guidance and recommendations relating to alarm transmission systems used in association with alarm systems.

NOTE 1 Alarm transmission systems (ATS) provide a means of sending alarm messages (such as fire, intrusion, access control or social alarm) away from the supervised premises to an alarm receiving centre.

This Published Document builds upon the existing BS EN 50136 series for alarm transmission systems by providing additional guidance, such as additional ATS performance categories and actions to be taken when the availability fails to meet the required levels, alongside fitting and installation advice to improve the security and reliability of ATS.

NOTE 2 See Annex A for installation guidance for intruder and hold-up alarm application.

This Published Document also includes recommendations to enable enhanced reporting of dual path failures.
