European foreword
This document (EN 50131-6:2017) has been prepared by CLC/TC 79 “Alarm systems”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2018-09-18
implemented at national level by publication of an
identical national standard or by endorsement
• latest date by which the national standards (dow) 2020-09-18
conflicting with this document have to
be withdrawn
This document supersedes EN 50131-6:2008.
The revision is to make the document less technology specific and more inclusive of the different
types of power supplies found in I&HAS and the different types of technologies that are, and can be,
employed within a power supply. It will make the document easier to use and more clearly applicable
to the range of PSU configurations to be found in I&HAS.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.

Introduction
This European Standard deals with power supplies (PS) of intrusion and hold-up alarm systems
(I&HAS) installed in buildings. It includes devices that are installed inside or outside of the supervised
premises and mounted in indoor or outdoor environments.
The PS may be fully contained in its own housing or it may be integrated with other components within
an I&HAS, e.g. the control and indicating equipment (CIE).
An I&HAS may use one or more PS.

1 Scope
This European Standard specifies the requirements, performance criteria and testing procedures for
PS to be used as part of Intrusion and Hold up Alarm Systems. The PS will either be an integral part of
an I&HAS component or stand-alone. The control functions of the PS may be incorporated as part of
the PS device, or may be provided by another I&HAS component, e.g. a CIE.
This European Standard is not applicable when the PS requirements for I&HAS components are
included within the relevant product standard.
The requirements correspond to each of the four security grades given in the European Standard
EN 50131-1, Alarm Systems – Intrusion and Hold-Up Systems – Part 1: System requirements.
Requirements are also given for four environmental classes covering applications in indoor and
outdoor locations.
This standard covers:
a) mandatory functions which will be provided on all PS; and
b) optional functions which may be provided.
This European Standard does not deal with requirements for compliance with EC regulatory
Directives, such as the EMC Directive, Low Voltage Directive, etc. except that it specifies the
equipment operating conditions and reduced functional test for EMC susceptibility testing as required
by EN 50130-4.
Other functions associated with I&HAS not specified in this standard may be provided. Such functions
will not affect the requirements of any mandatory or optional functions.

4.2 General requirements
The PS provides power for the components of an I&HAS derived from the prime power source.
The prime power source will normally be available to power the I&HAS for extended periods.
There are three types of PS which are independent of security grade and independent of the PS
configuration. These PS types are defined in EN 50131-1 and illustrated in Figure 2.
One or more PS may be used to meet the I&HAS standby requirements as specified in EN 50131-1.
For PS types A and B (see Figure 2):
— the EPS is the prime power source;
10

---------------------- Page: 12 ----------------------

SIST EN 50131-6:2018
EN 50131-6:2017 (E)
— the EPS is derived from either the principal prime power source or the supplementary prime
power source;
— the PPPS is the normal continuously available external source of power for the I&HAS, for
example the public mains supply;
— the SPPS provides an external back-up source of power in the event of loss of PPPS, for example
a standby generator;
— there is no requirement for the I&HAS to differentiate between the PPPS and SPPS as the source
of the EPS;
— an alternative power source provides a back-up source of power to the I&HAS components in the
event of loss of the EPS;
— the APS is derived from a SD which is housed within the PS.
NOTE 1 The PPPS may be a local source of power, for example a generator, with the SPPS
provided by the public mains electricity supply.
NOTE 2 The EPS may have a voltage and frequency other than that of the public mains electricity
supply, for example as provided from a low voltage battery bank.
For PS type C, the prime power source is derived from a SD which is housed within the PS.
A PS type A shall recharge the SD automatically from the EPS when the EPS is present, and maintain
it in a charged state.
NOTE There is no requirement for the charging to be continuous to maintain the SD in its charged state.
Where the SD in a PS type B is rechargeable, recharging of the SD shall be from an energy source
other than the EPS. This energy source may be non-continuous, e.g. derived from solar radiation.
A fault on one independent power output of a PS will have no impact upon the functionality of any
other independent power output.
Each independent power output may have provision for more than one connection.

Depending upon the security grade and PS type, the PS shall have the functionality as defined in
Table 1.
If a function is provided that is optional for a particular grade and a claim of compliance is made, it
shall meet the applicable requirements for the grade for which compliance is claimed (if any are
given). If there are no specifications for the optional function at the grade in question, the requirements
for any higher grade (as identified by the PS manufacturer) shall apply.

4.3 Monitoring of PS
4.3.1 General
The PS shall generate fault signals or messages for communication to the CIE according to Table 2.
Monitoring signals or messages shall be fail safe such that total loss of function of the PS will be
recognized as a fault condition by the I&HAS.
For integrated PS with configurations (ii) and (iii), the fault signals or messages may be communicated
to the CIE via the integrated component.

4.3.2 Loss of EPS
The EPS shall be monitored to detect when it can no longer provide the main supply of energy to
power the I&HAS.
A loss of EPS condition shall exist when the EPS has been continuously disconnected for a minimum
of 10 s and a maximum of 60 s.
An EPS Fault signal or message shall be generated within 10 s of the detection of Loss of EPS
condition.
A reconnection of EPS condition shall exist when the EPS has been continuously re-connected for a
minimum of 1 s and a maximum of 10 s.
An EPS Fault signal or message shall be removed within 10 s of the detection of reconnection of EPS
condition.
