Alarm systems - Alarm transmission systems and equipment - Part 2: Requirements for Supervised Premises Transceiver (SPT)
This European Standard specifies the general equipment requirements for the performance, reliability, resilience, security and safety characteristics of supervised premises transceiver (SPT) installed in supervised premises and used in alarm transmission systems (ATS). A supervised premises transceiver can be a stand-alone device or an integrated part of an alarm system. These requirements also apply to SPT’s sharing means of interconnection, control, communication and power supplies with other applications. 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. The term alarm is used in this broad sense throughout the document. Additional requirements for the connection of specific types of alarm systems are given in the relevant European Standards. Because the SPT can be applied in different applications (e.g. I&HAS, fire and social alarm systems), requirements for the SPT, additional to those of this European Standard, may be specified in separate application specific documents. This European Standard specifies the requirements specific to alarm transmission. Application specific requirements for the connection of the SPT to specific types of alarm systems are given in the EN 50131 (all parts) for I&HAS, and EN 54 (all parts) for fire. For other SPT applications, see the relevant National or European standards.

Systèmes d'alarme - Systèmes et équipements de transmission d’alarme - Partie 2: Exigences pour les transmetteurs des locaux surveillés (SPT)
La présente Norme Européenne spécifie les exigences matérielles générales relatives au fonctionnement, à la fiabilité, à la résilience, à la sécurité et à la sûreté des transmetteurs de locaux surveillés (SPT) installés dans des locaux surveillés et utilisés dans les systèmes de transmission d’alarme (ATS). Un transmetteur de locaux surveillés peut être un dispositif autonome ou faire partie intégrante d'un système d’alarme. Ces exigences s’appliquent également aux moyens de partage d’interconnexion, de commande, de communication et d’alimentation électrique du SPT avec d’autres applications. 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. Le terme alarme est utilisé dans ce sens large dans le document. D’autres exigences concernant le raccordement de types spécifiques de systèmes d’alarme sont données dans les Normes Européennes correspondantes. Du fait que le SPT peut être utilisé dans différentes applications (par exemple la détection d’intrusion et de hold-up (I&HAS) et les systèmes d’alarme incendie et sociale), des exigences concernant le SPT, s’ajoutant à celles de la présente Norme Européenne, peuvent être spécifiées dans des documents distincts spécifiques aux applications. La présente Norme Européenne spécifie les exigences propres à la transmission d’alarme. Les exigences spécifiques aux applications et relatives au raccordement du SPT à des types spécifiques de systèmes d’alarme sont données dans la EN 50131 (toutes parties) pour les I&HAS et dans la EN 54 (toutes parties) pour l’incendie. Pour les autres applications des SPT, voir les Normes nationales ou Européennes correspondantes.
Alarmni sistemi - Sistemi in oprema za prenos alarma - 2. del: Zahteve za oddajno-sprejemne naprave v nadzorovanih prostorih
Ta evropski standard določa splošne zahteve za značilnosti delovanja, zanesljivosti, odpornosti, varovanja in varnosti oddajno-sprejemnih naprav (SPT) v nadzorovanih prostorih, ki se uporabljajo v sistemih za prenos alarma (ATS). Oddajno-sprejemna naprava v nadzorovanih prostorih je lahko samostojna naprava ali sestavni del alarmnega sistema. Te zahteve veljajo tudi za oddajno-sprejemne naprave s skupnim načinom medsebojnega povezovanja, nadzora, komunikacije in napajanja z drugimi aplikacijami. Zahteve in klasifikacije sistemov za prenos alarma so določene s standardom EN 50136-1. Različne vrste alarmnih sistemov lahko poleg alarmnih sporočil pošiljajo tudi druge vrste sporočil, npr. sporočila o napakah in stanju. Izraz alarm se v tako širokem pomenu uporablja v celotnem dokumentu. Dodatne zahteve v zvezi s povezovanjem posebnih vrst alarmnih sistemov so navedene v ustreznih evropskih standardih. Ker je oddajno-sprejemne naprave mogoče uporabiti v različnih sistemih (npr. I&HAS, sistemih za javljanje požara in socialnih alarmnih sistemih), so zahteve za oddajno-sprejemne naprave, poleg zahtev v tem evropskem standardu, morda navedene v dokumentih za posamezne sisteme. Ta evropski standard določa zahteve, ki se nanašajo na prenos alarma. Zahteve za posamezne sisteme za priključitev oddajno-sprejemnih naprav na posebne vrste alarmnih sistemov so navedene v standardu EN 50131 (vsi deli) za I&HAS in standardu EN 54 (vsi deli) za požare. Za druge oddajno-sprejemne naprave si oglejte ustrezne nacionalne ali evropske standarde.

This European Standard is part of a series. This series is intended to give the requirements applicable
to alarm transmission systems in general.
EN 50136 consists of the following parts, under the general title Alarm systems — Alarm transmission
systems and equipment:
– Part 1: General requirements for alarm transmission systems;
– Part 2: Requirements for Supervised Premises Transceiver (SPT);
– Part 3: Requirements for Receiving Centre Transceiver (RCT);
– Part 4: Annunciation equipment used in alarm receiving centres (Technical Specification);
– Part 7: Application guidelines (Technical Specification);
– 5 – EN 50136-2:2013
– Part 9: Requirements for common protocol for alarm transmission using the Internet protocol
(Technical Specification).
1 Scope
This European Standard specifies the general equipment requirements for the performance, reliability,
resilience, security and safety characteristics of supervised premises transceiver (SPT) installed in
supervised premises and used in alarm transmission systems (ATS). A supervised premises
transceiver can be a stand-alone device or an integrated part of an alarm system.
These requirements also apply to SPT’s sharing means of interconnection, control, communication
and power supplies with other applications.
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. The term alarm is used in this broad sense
throughout the document. Additional requirements for the connection of specific types of alarm
systems are given in the relevant European Standards.
Because the SPT can be applied in different applications (e.g. I&HAS, fire and social alarm systems),
requirements for the SPT, additional to those of this European Standard, may be specified in separate
application specific documents.
This European Standard specifies the requirements specific to alarm transmission. Application specific
requirements for the connection of the SPT to specific types of alarm systems are given in the
EN 50131 (all parts) for I&HAS, and EN 54 (all parts) for fire. For other SPT applications, see the
relevant National or European standards.

4 General requirements
4.1 General
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 SPT is used together
with or integrated in associated alarm systems, the requirements of the specific applications or related
standards shall apply.
Specific applications may require additional testing of the SPT. If such characteristics for a non-alarm
application are provided and are submitted for testing, they shall be specified by the manufacturer at the
time of testing.
4.2 SPT classification
This European Standard defines SPT requirements. For some specific characteristics also, a
classification system or measuring scale is introduced. For the purpose of SPT classification,
reference is made to the ATS categories in EN 50136-1. The SPT shall be labelled with each category
or range of categories that it can be applied to.
If a Custom Category (category C) is defined then the requirements corresponding to Tables 1, 2
and 3 shall also be defined.
5 Functional requirements
5.1 General
The SPT shall be able to receive alarms from one or more ASs and transmit the alarm to one or more
RCTs via one or more ATPs within the requirements of the appropriate ATS category.
5.2 Access levels
This European Standard specifies four levels of access that categorise the ability of users to gain
logical access to the SPT functions.
Physical access requirements may be defined in the relevant application specific standards.
Access levels are defined as following:
− Level 1: access to functions, indications and notifications available to any individual without
authentication;
− Level 2: access to information about the operational status of the SPT. Access level 2 may
also allow access to basic functional tests and the management of other Access
level 2 users;
− Level 3: maintenance and commissioning functions, access to affect the SPT configuration
including the addition, removal or replacement of components and other operations
that directly, or indirectly, may influence the functions of the SPT;
− Level 4: access to update the software and read-only functions.
Access to level 2, 3 and level 4 functions shall require authorisation with a key.
Access at level 3 should be authorised by a user with level 2 access. Access at level 4 should be
authorised by a user with level 3 access. This may be achieved by a one time authorisation as part of
a service level agreement.
Access at levels 2, 3 and 4 may be achieved providing authorisation, equivalent to 1 000 000 key
differs is achieved.
Where it is possible to attempt to gain access more than 3 times in a 60-second period the SPT 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 SPT commissioning
without first, changing these keys e.g. during installation. It shall not be possible to read any key that
provides authorisation for access at levels 2, 3 or 4.
– 9 – EN 50136-2:2013
5.3 Remote access
Remote access to the SPT shall meet at least the same information security requirements that are
required for alarm transmission as defined in EN 50136-1 for the appropriate category.
5.4 Uploading and downloading of software and firmware
Where upload and download functions are provided, the upload and download of software to a SPT is
only allowed to be performed by users with appropriate access level, as defined in 5.2.
The software to be replaced by a software download shall be stored. If there is a loss of connection or
another transmission fault disrupts the download, the last fully functional software version shall be
restored, and the SPT shall work as before the unsuccessful download.
EXAMPLE Procedure of a download: download software, check and validate the download, activate downloaded software.
5.5 Storage of parameters
Power cycle or a boot up sequence shall not result in the loss of any site specific data. The SPT shall
return to normal operation.
5.6 ATS and ATP fault reporting to the AS
Where the SPT is required to report an ATS and/or ATP failure to the AS as per EN 50136-1:2012,
Table 5, this shall take place within the reporting times shown in EN 50136-1:2012, Table 3.
For an ATS with more than one ATP, as long as service is not lost, a single path line fault may be held
by the SPT for a period that is agreed between the interested parties until it is released to the AS.
Where an AS includes the ability to display the status of each ATP the SPT may be configured to pass
individual ATP failures to the AS within the reporting times shown in EN 50136-1:2012, Table 3.
The manufacturer’s documentation should define the process for the reporting of ATS faults to the AS.
5.7 Interface to the AS
The connections to the AS shall be monitored in accordance with EN 50136-1.
The maximum time to detect and generate an interface failure shall meet the requirements of the
associated application and shall not exceed the ATS reporting time of the appropriate category as
specified in EN 50136-1:2012, Table 3.
To allow compatibility of equipment from different manufacturers, this European Standard specifies
two electrical interfaces:
• parallel interface between AS and SPT, see A.1;
• serial interface between AS and SPT, see A.2.
This does not exclude the use of any other type of interface to the AS, provided that the specific
requirements of this standard are met.
The manufacturer shall state in the associated documentation which type(s) of interface(s) to the AS
are provided.
5.8 Monitoring of the transmission network interface(s) – Fault reporting
If required by the ATS category, the SPT shall be configured to detect the failure of a transmission
network interface and generate an ATP fault to the AS.
The manufacturer's documentation shall describe the process for monitoring and reporting the network
interface fault to the AS.
NOTE 1 The message generated by the SPT can indicate either an ATP fault or an interface fault.
Where required, transmission network interface faults shall be reported within the time specified in
EN 50136-1:2012, Table 3.
For dual path category (Dx) ATSs, a fault on one of the transmission network interfaces shall be
reported to the RCT over the remaining ATP within the time specified in EN 50136-1.
NOTE 2 An SPT network interface fault provides indication of a path fault.
Monitoring the state of a transmission network interface should not be used to monitor the state of an
associated ATP.
NOTE 3 An ATP can be in a failed state whilst the associated network interface is in an operational state.
5.9 Power supply for the SPT
The SPT may be powered by the associated AS power supply (dedicated or shared) or by an integral
SPT power supply.
Where an integral SPT power supply is used, it shall meet the requirements of the most demanding
associated AS.
5.10 Event logging
A logging function for all categories of SPT except SP1 and DP1, shall be provided for the purposes of
providing an audit trail and problem resolution.
Dependent upon the ATS category where the SPT is applied, the events specified in Table 1 shall be
recorded in the SPT.
The means used to record the events shall be protected against the accidental or deliberate deletion
or alteration of the contents.
The means of recording events shall be non-volatile and have a capacity complying with the
requirements of Table 2. When the event recorder reaches maximum capacity, further events may
cause the oldest events to be erased.
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 SPT shall provide a means to adjust the date and time.
Event optimisation is permitted, provided that all diverse events are recorded and that the first and the
last repeated identical sequence of events in a 12 h period are recorded. Where this is done the
number of repetitions need to be recorded.
When required by Table 1, the logging of access to the SPT shall include user identification.
– 11 – EN 50136-2:2013
The inclusion of requirements to record events in Table 1 does not imply a requirement to provide the
associated function.

capacity and endurance for SPT events meet the requirements of this table.
6 Operation
6.1 Modes of acknowledgement operation
6.1.1 General
Two modes of operation are permitted:
a) store-and-forward;
b) pass-through.
The manufacturer shall declare in the product documentation which of the two modes are supported.
6.1.2 Store-and-forward operation requirements
When an alarm is received from the AS, the SPT shall secure the alarm and provide acknowledgment
of the correct receipt of the alarm to the AS.
If the store-and-forward operation is used, all alarm messages shall include a date and time stamp
that is accurate to the resolution specified in 5.10.
Securing the alarm shall be achieved by storing the alarm in the SPT’s non-volatile memory, this is to
secure alarms during a power failure or other ATS failure; stored alarms shall be transmitted when the
fault condition clears.
The secured message shall be transmitted from the SPT to the RCT.
The reception of an acknowledgement from the RCT shall not be forwarded to the AS, since the AS
has already received an acknowledgement from the SPT.
NOTE The loss of an alarm message is regarded as a worse situation than sending a delayed message.
6.1.3 Pass-through operation requirements
When an alarm is received from the AS the SPT shall forward the alarm to the RCT.
The SPT shall not acknowledge the alarm to the AS before receiving an acknowledgement from the
RCT. When the SPT receives an acknowledgement from the RCT, the acknowledgement shall be
forwarded to the AS.
Pass-through operation may be used in systems where the application requires receipt of
acknowledgement from the AE.
6.2 SPT alarms
The SPT shall be able to generate and transmit to the RCT the alarms specified in Table 3 for the
appropriate category.
