Introduction
To come to a common understanding of the alarm transmission standards documents there is a need for application guidelines to support other TC 79 WG, other standardisation bodies, insurance companies and customers to require an appropriate performance of the alarm transmission system for a specific application.
Application knowledge and needs are not always available by the alarm transmission experts and therefore guidelines for alarm transmission should assist other experts to understand the alarm transmission standards and the performance of an alarm transmission system. This should help to make an appropriate specification based on the performance tables of the general standard, also including the economical aspects and consequences.
The alarm transmission standards applies to different applications (e.g. intrusion, fire, access control, CCTV,...). Therefore, this guideline should be read in conjunction with the standards relating to these applications when appropriate.
Several alarm transmission systems may be used by the providers of alarm transmission services, which implies that the level of services may vary, depending on the performance of each alarm transmission system.
1 Scope
This Technical Specification will give to the readers of the alarm transmission system standards appropriate guidance to define alarm transmission and annunciation equipment systems in line with the requirements of their specific applications.

For the purposes of this Technical Specification, the definitions in EN 50136-1-1 apply.
4 Alarm transmission systems
4.1 General and technology specific requirement
Alarm transmission systems are a part of a total security solution. The selection of requirements for the alarm transmission system depends on the requirements of the specific application.
The alarm transmission standards parts EN 50136-1-1 and EN 50136-2-1 are the main documents. They provide requirements for all types of systems and equipment commonly in use.
For some specific technologies there are standards providing detailed additional requirements or interpretations or explanations for the application of the general requirements.
For technologies not covered by a specific standard document, the general documents EN 50136-1-1 and EN 50136-2-1 should apply.
4.2 Purpose of an alarm transmission system
The purpose of an alarm is always to initiate some kind of response, locally or remotely. The function of the alarm is in some cases twofold, to prevent something from occurring, e.g. burglary, and to respond when something occurs. The most common set-up is with an alarm equipment including detection of the expected incidents, an alarm transmission system, a monitoring centre and a response force, police, guards, fire brigade, medical assistance, etc.
The characteristics of each of these parts of the total preventive and responsive system should correspond to the nature of the threat, for which it provides protection:
•? for a burglar alarm, tamper and manipulation protection are important characteristics: the higher the values or risks, the more important is also the availability of the system;
•? for a fire alarm system the most important characteristics may be transmission time and availability, of course related to the values at risk).
Sufficient information should be provided through the alarm transmission system to enable appropriate intervention.
Examples of useful information are
•? fault,
•? set/unset (arm/disarm),
•? alarm including type, location and also detector or zone,
•? power failure/battery fault. 4.3 Components of an alarm transmission system (Annex A)
The alarm transmission system has several parts. The supervised premises transceiver is the part which is located at the premises and which receives the alarm status signal(s) from the local alarm system. It transmits the corresponding alarm through a transmission network (which is, in most cases, a network provided by a telephone network operator), to a receiving centre transceiver located in a remote centre or in an alarm receiving centre.
The message corresponding to the alarm is then passed to the annunciation equipment, which secures its presentation. The annunciation equipment can be either located
