Alarm systems - Part 4: Electromagnetic compatibility - Product family standard: Immunity requirements for components of fire, intruder, hold up, CCTV, access control and social alarm systems

This EMC product-family standard, for immunity requirements, applies to the components of the following alarm systems, intended for use in and around buildings in residen¬tial, commercial, light industrial and industrial environments: – access control systems, for security applications; – alarm transmission systems 1); – CCTV systems, for security applications; – fire detection and fire alarm systems; – hold-up alarm systems; – intruder alarm systems; – social alarm systems; The tests and severities to be used are the same for indoor and outdoor applications of fixed, movable and portable equipment. The levels do not cover extreme cases, which may occur in any location, but with an extremely low probability of occurrence, or in special locations close to powerful emitters (e.g. radar transmitters). Equipment within the scope of this standard should be designed in order to operate satisfactorily in the environmental electromagnetic conditions of residential, commercial, light industrial and industrial environments. This implies particularly that it should be able to operate correctly within the conditions fixed by the electromagnetic compatibility levels for the various disturbances on the low voltage public supply system as defined by EN 61000 2 2. The immunity tests in this standard only concern the most critical disturbance phenomena. For equipment using radio signalling, mains signalling or with connections to the public telephone system, additional requirements, from other standards specific to these signalling media, might apply. This standard does not specify basic safety requirements, such as protection against electrical shocks, unsafe operation, insulation coordination and related dielectric tests. This standard does not cover EMC emission requirements. These are covered by other appropriate standards.

Alarmni sistemi - 4. del: Elektromagnetna združljivost - Standard za varnost proizvodov - Zahteve za odpornost sestavnih komponent požarnih, vlomnih in socialnih alarmnih sistemov

Ta standard družine proizvodov EMC glede zahtev za odpornost velja za sestavne dele naslednjih alarmnih sistemov za uporabo v stavbah in okoli njih v stanovanjskih, gospodarskih, lahkih industrijskih in industrijskih okoljih: - sisteme za nadzor dostopa za varnostne uporabe; - sisteme za prenos alarmov; - sisteme CCTV za varnostne uporabe; - sisteme za odkrivanje in javljanje požara; - alarmne sisteme za javljanje ropa; - alarmne sisteme za javljanje vloma; - socialne alarmne sisteme. Preskusi in natančnost so enaki za uporabo fiksne, premične in prenosne opreme v zaprtih prostorih in na prostem. Stopnje ne zajemajo skrajnih primerov, ki lahko nastanejo na vsaki lokaciji, vendar ob izredno nizki verjetnosti pojava ali na posebnih lokacijah blizu močnih oddajnikov (npr. radarski oddajniki). Oprema v okviru področja uporabe tega standarda mora biti načrtovana tako, da zadovoljivo deluje v elektromagnetnih okoljskih razmerah stanovanjskih, gospodarskih, lahkih industrijskih in industrijskih okolij. To predvsem pomeni, da mora biti zmožna pravilno delovati v okoliščinah, ki jih določajo stopnje elektromagnetne skladnosti za različne motnje nizkonapetostnega javnega oskrbovalnega sistema, kot je opredeljeno v EN 61000-2-2. Preskusi odpornosti v tem standardu se nanašajo le na najbolj kritične pojave motenj. Za opremo, ki uporablja radiosignalizacijo, omrežno signalizacijo ali ima povezave z javnim telefonskim sistemom, lahko veljajo dodatne zahteve iz drugih standardov, določenih za te signalne medije. Ta standard ne določa osnovnih varnostnih zahtev, kot so zaščita proti nevarnostim električnega šoka, nevarno delovanje, izolacijska koordinacija in povezani dielektrični preskusi. Ta standard ne zajema zahtev glede EMC pri oddajanju motenj. Te so zajete v drugih ustreznih standardih.

Overview

EN 50130-4:2011 - Alarm systems - Part 4: Electromagnetic compatibility - Product family standard - Immunity requirements - specifies electromagnetic immunity requirements for components of alarm systems used in and around buildings (residential, commercial, light industrial and industrial). It covers components for access control, alarm transmission, CCTV, fire detection and fire alarm, hold-up, intruder and social alarm systems. The standard defines the immunity tests, test conditions and compliance criteria intended to ensure reliable operation of alarm system components in typical electromagnetic environments.

Key topics and technical requirements

• Scope and applicability: Applies to fixed, movable and portable equipment; indoor and outdoor use. Levels exclude extremely low‑probability cases (e.g., very close to powerful radar).
• Immunity test types (based on referenced basic EMC standards):
  • Mains supply voltage variations, dips and short interruptions (EN 61000‑4‑11)
  • Electrostatic discharge (ESD) (EN 61000‑4‑2)
  • Radiated RF fields (EN 61000‑4‑3)
  • Conducted disturbances induced by RF fields (EN 61000‑4‑6)
  • Fast transient/burst (EN 61000‑4‑4)
  • Surge (slow high energy voltage surge) (EN 61000‑4‑5)
  • Conducted common‑mode disturbances up to 150 kHz
• Testing framework: Defines test configuration, environmental and operating conditions, functional test procedures and pass/fail criteria tailored for alarm components (functional performance during and after disturbances).
• Limitations: Does not cover EMC emissions, basic electrical safety (insulation, shock protection), or special signalling media (radio, mains signalling, public telephone lines) which may require additional standards.

Practical applications

• Product design: Guides designers to achieve robust EMC immunity for alarm system components so they continue to operate correctly in real‑world electromagnetic environments.
• Type testing and certification: Used by test laboratories and certification bodies to define and perform immunity tests for compliance and product approvals.
• System specification and procurement: Helps specifiers and procurement teams require EMC‑immune components for reliable security, fire and social alarm installations.
• Installation and integration: Informs system integrators and installers about expected immunity performance and environmental limitations (e.g., near high‑power transmitters).

Who uses this standard

• Manufacturers of alarm system components (CCTV cameras, detectors, control panels, access readers)
• EMC test laboratories and certification agencies
• System integrators, consultants and specifiers in security and fire alarm sectors
• Regulatory and compliance teams assessing conformity with EMC directives

Related standards

• EN 50130 series (alarm systems) and product standards: EN 50131, EN 50132, EN 50133, EN 50134, EN 50136, EN 54 (fire)
• Basic EMC test standards: EN 61000‑4‑2/3/4/5/6/11/20
• ETSI EN 301 489 (radio equipment EMC)

Using EN 50130-4:2011 in product development and testing helps ensure alarm components meet established EMC immunity expectations for reliable operation in typical built environments.

1 Scope
This EMC product-family standard, for immunity requirements, applies to the components of the
following alarm systems, intended for use in and around buildings in residential, commercial, light
industrial and industrial environments:
– access control systems, for security applications;
1)
– alarm transmission systems ;
– CCTV systems, for security applications;
– fire detection and fire alarm systems;
– hold-up alarm systems;
– intruder alarm systems;
– social alarm systems;
The tests and severities to be used are the same for indoor and outdoor applications of fixed, movable
and portable equipment.
The levels do not cover extreme cases, which may occur in any location, but with an extremely low
probability of occurrence, or in special locations close to powerful emitters (e.g. radar transmitters).
Equipment within the scope of this standard should be designed in order to operate satisfactorily in the
environmental electromagnetic conditions of residential, commercial, light industrial and industrial
environments. This implies particularly that it should be able to operate correctly within the conditions
fixed by the electromagnetic compatibility levels for the various disturbances on the low voltage public
supply system as defined by EN 61000-2-2. The immunity tests in this standard only concern the most
critical disturbance phenomena.
For equipment using radio signalling, mains signalling or with connections to the public telephone
system, additional requirements, from other standards specific to these signalling media, might apply.
This standard does not specify basic safety requirements, such as protection against electrical shocks,
unsafe operation, insulation coordination and related dielectric tests.
This standard does not cover EMC emission requirements. These are covered by other appropriate
standards.

4 Application of the tests
The tests shall be carried out as single tests, as described in the later clauses, and the equipment shall
meet the criteria for compliance for each test. If a number of tests are made on a single specimen of the
equipment, the sequence of testing is optional, and it is permissible to substitute the intermediate
functional tests with a reduced version of the functional test and to conduct a full functional test at the
end of the sequence. However, it should be noted that, in this case, in the event of a failure, it may not
be possible to identify which test exposure caused the failure.
Where appropriate basic EMC standards exist, these are referred to in the relevant clauses. The content
of these basic EMC standards (i.e. the description of the test procedure, test apparatus and test set-up)
are not repeated here in full, however modifications or additional information needed for the particular
application of the tests are given in this standard.
It may be determined, from consideration of the electrical characteristics and usage of particular
equipment, that some of the tests are inappropriate and therefore unnecessary. In such a case it is
required that the decision not to conduct the test be recorded in the report, along with the justification for
this decision.
5 Conditions during testing
5.1 Configuration
If the EUT is part of a system, or can be connected to other equipment, then the EUT shall be tested
while connected in at least the minimum configuration necessary for verifying its performance.
If the EUT has a large number of inputs/outputs, then a sufficient number shall be selected to simulate
actual operating conditions and to ensure that all the different types of inputs/outputs are covered. The
connections to inputs and outputs, which may be separated into different cables in a real installation,
shall be separated into different cables for the tests (e.g. detector loops).
Any external cables that are part of or attached to the EUT and or ancillary equipment shall be
documented in the test report. The minimum information provided shall be the cable type, length,
termination and to which port they are attached.
During conditioning, the EUT shall be monitored to detect any change in its status, including any change
in outputs, which could be interpreted by associated equipment as a change in status.
5.2 Environmental conditions
Unless otherwise indicated in the basic standard or test procedure, the tests shall be carried out within
the rated supply voltage for the EUT and the following standard atmospheric conditions for
measurements and tests, as specified in EN 60068-1:1994, 5.3.1:
– temperature : 15 °C to 35 °C;
– relative humidity : 25 % to 75 %;
– air pressure : 86 kPa to 106 kPa.
5.3 Operating conditions
Where a relevant European product performance standard (EN) exists, which defines suitable operating
condition(s) during environmental or EMC tests (e.g. EN 54 series for fire alarm systems, EN 50131
series for intruder alarm systems), the operating condition(s) of the EUT, during the test conditions, shall
be as defined in that standard.

– 9 – EN 50130-4:2011
Where no relevant European product performance standard (EN) exists, the operating condition(s) of the
EUT, during the test conditioning, shall include at least that corresponding to the main functional mode
(appropriate to the test being undertaken) of the system, which it forms part of. (e.g. corresponding to the
"set" mode, for an intruder alarm system during a radiated immunity test).
The configuration and mode(s) of operation during the tests shall be precisely noted in the test report.
6 Functional test
The variety and the diversity of the equipment within the scope of this standard makes it difficult to define
a precise functional test for evaluation of the EUT performance:
– where a relevant European product performance standard (EN) exists, which defines suitable
operating condition(s) during environmental or EMC tests (e.g. EN 54 series for fire alarm
systems, EN 50131 series for intruder alarm systems), the operating condition(s) of the EUT,
during the test conditions, shall be as defined in that standard;
– where no relevant European product performance standard (EN) exists, the functional test shall
be at least a test or measurement of the main function(s) of the equipment. The acceptance
criteria for this functional test shall be that there is no change in the functioning of the equipment
and no significant change in any measurement (e.g. sensitivity of a detector), which shall also
remain within specification.
7 Mains supply voltage variations
7.1 Object of the test
To demonstrate the ability of the equipment to function correctly over the anticipated range of mains
supply voltage conditions.
7.2 Principle
The test consists of exposing the specimen to each of the maximum and minimum power supply
conditions, for a sufficient time to obtain temperature stability, and to perform the functional test.
7.3 Test procedure
7.3.1 General
No reference can be made to an internationally accepted standard at present.
7.3.2 Initial examination
Before the conditioning, subject the specimen to the functional test (see Clause 6).
7.3.3 State of specimen during conditioning
Connect the specimen to suitable power supply, monitoring and loading equipment (see 5.1). The
specimen shall be in its operating condition (see 5.3).
7.3.4 Conditioning
Subject the specimen to each of the power supply conditions, indicated in Table 1, until temperature
stability is reached.

7.3.5 Measurements during conditioning
Monitor the specimen during the conditioning to detect any change in status. When temperature stability
has been obtained, at each of the supply conditions, subject the specimen to the functional test (see
Clause 6).
7.3.6 Final measurements
After the conditioning at both of the specified power supply conditions inspect the specimen visually for
mechanical damage.
7.4 Criteria for compliance
There shall be no damage, malfunction or change of status due to the different supply voltage
conditions.
The EUT shall meet the acceptance criteria for the functional test (see Clause 6), during the conditioning.
NOTE It is the view of CLC/TC 79 that the above requirement is not an EMC test but more of a performance test. On the next
maintenance cycle, this requirement will be removed from this standard. It was not removed on this revision in order to allow
performance standards working groups who require their devices to meet this test, to have some time to add it into their
standards and therefore maintain continuity.
8 Mains supply voltage dips and short interruptions
8.1 Object of the test
To demonstrate the immunity of the equipment to short duration dips (reductions) and interruptions in the
A.C. mains voltage, such as those caused by load switching and operation of protection devices on the
mains distribution network.
8.2 Principle
The test consists of applying short duration dips and interruptions to the A.C. mains supply to the
equipment.
8.3 Test procedure
8.3.1 General
The test apparatus and procedure shall be as described in EN 61000-4-11.
8.3.2 Initial examination
Before the conditioning, subject the specimen to the functional test (see Clause 6).

8.3.3 State of specimen during conditioning
Connect the specimen to a suitable power supply, monitoring and loading equipment (see 5.1). The
specimen shall be in its operating condition (see 5.3).
8.3.4 Conditioning
Reduce the A.C. mains supply voltage from the nominal value by the following reductions for the
specified periods, in accordance with Table 2. The voltage changes shall occur at the zero crossings of
the voltage wave.
