Systèmes d'alarme - Systèmes et équipements de transmission d'alarme - Partie 3: Exigences pour les transmetteurs du centre de réception (RCT)

La présente Norme Européenne spécifie les exigences matérielles minimales relatives au fonctionnement, à la fiabilité, à la résilience, à la sécurité et à la sûreté des transmetteurs du centre de réception (RCT) installés dans l'ARC et utilisés dans les systèmes de transmission d’alarme. Les exigences et les classifications des systèmes de transmission d’alarme sont définies dans la EN 50136-1. Différents types de systèmes d’alarme peuvent, outre des messages d’alarme, envoyer d’autres types de messages, par exemple des messages de défaut et des messages d’état. Ces messages sont également considérés comme des messages d'alarme. Le terme message d'alarme est utilisé dans ce sens large dans le document. Si des normes spécifiques à l'application existent, il convient que le RCT satisfasse aux normes correspondantes mentionnées par cette application. Le RCT peut être soit un élément intégré d'équipement de réception/d'annonce, soit un dispositif autonome. Dans les deux cas, il convient que les exigences de la présente Norme Européenne s'appliquent. Le RCT a pour fonction de surveiller les ATP, de recevoir les messages d'alarme, de transmettre les messages d'alarme vers un ou plusieurs AE et d'envoyer des accusés de réception aux SPT. La gestion du réseau de transmission ne fait pas partie du domaine d’application de la présente Norme Européenne.

1 Scope

This European Standard specifies the minimum equipment requirements for the performance,

reliability, resilience, security and safety characteristics of the receiving centre transceiver (RCT)

installed in ARC and used in alarm transmission systems.

The alarm transmission system requirements and classifications are defined within EN 50136-1.

Different types of alarm systems may in addition to alarm messages also send other types of

messages, e.g. fault messages and status messages. These messages are also considered to be

alarm messages. The term alarm message is used in this broad sense throughout the document.

Where application specific standards exist, the RCT should comply with relevant standards called up

by that application.

The RCT can be either an integrated element of any receiving/annunciation equipment, or a stand-

alone device. In either case, the requirements of this European Standard should apply.

The function of the RCT is to monitor the ATPs, receive alarm messages, forward alarm messages to

one or more AEs and send acknowledgements to the SPTs.

Management of the transmission network is not in the scope of this European Standard.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

reliability, resilience, security and safety characteristics of the Receiving Centre Transceiver (RCT)

installed in alarm receiving centres and to define parameters that shall be tested to ensure its

compatibility with ATS categories.
---------------------- Page: 7 ----------------------
SIST EN 50136-3:2014
EN 50136-3:2013 - 6 -
5 General
5.1 Introduction

Where appropriate, equipment shall comply with local, national and European requirements and

regulations for connection and transmission via public or private networks.

Requirements in this European Standard shall be considered as a minimum. As the RCT is used together

with or integrated receiving/annunciation equipment, the requirements of the specific applications or

related standards shall apply.
5.2 RCT classification

This European Standard defines RCT requirements. For the purpose of RCT classification reference is

made to the ATS categories in EN 50136-1. The RCT documentation shall describe for which ATS

categories the RCT complies with the requirements.
6 Functional requirements
6.1 General

The RCT shall provide communication between one or more AEs and one or more SPTs and monitor

the interface(s) to one or more AEs.
The RCT shall monitor the ATSs.
6.2 Access levels

This European Standard specifies four levels of access that categorise the ability of users to access

the RCT functions.
Access levels are defined as following:
- Level 1 Access to indications;
- Level 2 Access to the operational status and commissioning functions;

- Level 3 Maintenance functions, access to affect the RCT configuration including site-specific data

and other operations that directly, or indirectly, may adversely influence the functions of

the RCT;
- Level 4 Access to software updates and read-only parameters.

These access levels apply only for logical access (i.e. not physical access). Access to all functions

shall require authorisation with a key.

Access levels 2, 3 and 4 shall use personalised accounts to achieve traceability.

A level 4 user shall be authorised by a user with level 3 access. This authorisation may be permanent

or time limited.

Access at all levels shall require authorisation with a key. The key mechanism shall be able to provide

at least 1 000 000 different keys.
---------------------- Page: 8 ----------------------
SIST EN 50136-3:2014
- 7 - EN 50136-3:2013

Where it is possible to attempt to gain access more than 3 times in a 60-second period the RCT shall

have the ability to delay repeated attempts. After the third attempt, each further attempt shall be

prevented for a minimum of 90 s.

Where factory default keys are provided, it shall not be possible to complete the RCT commissioning

without first, changing these keys during installation.

Remote access shall require a secure connection and meet the data security requirements of

EN 50136-1.

Automatic logout of remote access sessions shall be activated after a period of inactivity. The inactivity

period shall be configurable.

NOTE The requirement to restrict or permit access to a certain function does not imply that implementation of the function

is required.
6.3 Uploading and downloading of software

The upload and download of software in/out of an RCT is only allowed at appropriate access level as

defined in 6.3.

SIST EN 50136-3:2014
EN 50136-3:2013 - 8 -
6.4 Storage of parameters and data

Power cycle or a software restart shall not result in the loss of any configuration, log and secured

alarm messages. The RCT shall return to normal operation automatically after such power cycle or

software restart.
6.5 Monitoring and notification of failure of the ATP and ATS

For compliance to the relevant standards of the application, the RCT shall monitor ATP and ATS and

report failures to the AE as defined in EN 50136-1:2012, 6.6, Table 4.

The documentation supplied by the manufacturer shall describe the notification signal.

6.6 Interface(s) to the AE(s)

The interface(s) to the AE(s) shall be monitored in accordance with EN 50136-1. The reporting time of

the connection failure shall be less or equal to the reporting time of the ATS with the highest category

or 60 s whichever is shorter. In the event of an interface failure, a fault signal shall be generated, and

an event logged.

The manufacturer shall state in their product documentation the specifications of the interface(s) to the

AE and how the fault signal is presented and logged.
An alternative AE interface may be provided.
6.7 Fault signalling

The RCT shall have a means to signal faults when any of the following faults occur:

- AE interface failure;
- transmission network interface failure;
- RCT system failure.

The manufacturer shall specify in the RCT documentation how these faults are signalled.

6.8 Event recording

For an RCT supporting and meeting any category of EN 50136-1:2012 other than SP1, SP2 and DP1

a logging function shall be provided for the purposes of providing an audit trail and problem resolution.

The events specified in Table 2 shall be recorded.
The event log may be stored outside of the RCT.

The means of recording events shall be non-volatile. The log entries shall be kept for no less than 3

years. The manufacturer shall specify in their documentation how this is achieved.

Events older than 3 years may be deleted.

The log shall record, in addition to the event, the time and date at which the event occurred. The

timing resolution shall be a minimum of 1 s and it shall be accurate to the coordinated universal time

within ± 5 s.

The RCT shall provide a means to synchronise the UTC date and time. The manufacturer shall specify

in their documentation how time synchronisation with UTC is achieved.
---------------------- Page: 10 ----------------------
SIST EN 50136-3:2014
- 9 - EN 50136-3:2013
The RCT may use local time-zones.

To optimise storage of events, where identical sequentially repeated events occur within any 12-h

period, then only the first and last event need to be recorded. Where this is done then the number of

identical events shall be recorded.

When required by the requirements of Table 2, the logging of access to the RCT shall include user

identification.

n/a = Not applicable
M = Mandatory

NOTE Recording the user identification is only mandatory if the event is triggered by user intervention.

6.9 Mode of operation (store-and-forward or pass-through)
6.9.1 General
Two modes of operation are permitted:
a) store-and-forward;
b) pass-through.

The manufacturer shall declare in the product documentation which modes are supported.

6.9.2 Store-and-forward operation requirements

When an alarm is received from the SPT, the RCT shall secure the alarm and provide

acknowledgement of the correct receipt of the alarm to the SPT.

If the store-and-forward operation is used, all alarm messages shall include the date and time stamp

when the alarm was received by the SPT.

The RCT may also log the date and time stamp when the alarm was forwarded to the AE and/or when

the acknowledgement was received from the AE.

Securing the alarm shall be achieved by storing the alarm in the RCT’s non-volatile memory (data

base), this is to secure acknowledged alarms whilst there is an AE interface failure or during a power

failure. Stored alarms shall be transmitted when the fault condition clears.
The secured alarm shall be transmitted from the RCT to the AE(s).
---------------------- Page: 11 ----------------------
SIST EN 50136-3:2014
EN 50136-3:2013 - 10 -

The reception of an acknowledgement from the AE(s) shall not be forwarded to the SPT, since the

SPT has already received an acknowledgement from the RCT.

NOTE The loss of an alarm message is regarded as a worse situation than sending a delayed message.

6.9.3 Pass-through operation requirements

When an alarm is received from the SPT the RCT shall forward the alarm to the AE(s).

The RCT shall not acknowledge the alarm to the SPT before receiving an acknowledgement from at

least one AE. When the RCT receives an acknowledgement from the AE(s) the acknowledgement

shall be forwarded to the SPT.
6.10 Denial of service

The manufacturer of the RCT shall declare in their documentation how compliance with the

requirements of EN 50136-1:2012, 6.2.5 is achieved.
6.11 Information security

The manufacturer shall provide their stated methodology used to achieve compliance with

EN 50136-1:2012, 6.8.3 (Information security) for both SPT communication and remote access.

6.12 Substitution security

The manufacturer shall provide their stated methodology used to achieve compliance with

EN 50136-1:2012, 6.8.2 (Substitution security).
6.13 RCT redundancy

If the RCT supports Dual Path category ATS (DP1 – DP4) the RCT shall comply with the redundancy

requirements of EN 50136-1:2012, Table 1. The manufacturer shall specify and demonstrate how

compliance is achieved.
6.14 Documentation

Documentation relating to an RCT shall be concise, complete and unambiguous. Information shall be

provided sufficient to install, put into operation, operate and maintain an RCT.

Instructions relating to the operation of an RCT shall be designed to minimise the possibility of

incorrect operation and be structured to reflect the access level of the user.

Where there are user serviceable parts (e.g. fuses) their type and values shall be given.

The documentation shall include:
- name of manufacturer or supplier,
- description of equipment,
- standard to which component claims compliance,
- name or mark of the certification body,
- the maximum number of SPTs that can be connected for each category,
- the maximum number of AEs that can be connected,

6.15 Marking/identification
The RCT shall be marked with the following:
- name of manufacturer;
- ATS categories for which the RCT is suitable.

The marking shall be legible, durable and unambiguous. If the RCT does not use dedicated hardware

(i.e. the RCT is a software solution), the software shall be able to display the required

markings/identifications.
