prEN 50130-4:2026 is a draft European Standard from CLC on electromagnetic compatibility (EMC) immunity for alarm-system components. It specifies how equipment used in access control, alarm transmission, video surveillance, fire detection and fire alarm, hold-up alarm, intruder alarm, and social alarm systems is tested for immunity in residential, commercial, light industrial, and industrial environments. It is written for manufacturers, test laboratories, and system specifiers who need a common immunity test basis for fixed, movable, and portable equipment.
What does prEN 50130-4:2026 specify?
prEN 50130-4:2026 specifies immunity requirements for EMC and the test approach used to check them. The standard covers indoor and outdoor applications of the listed alarm and security system components, so the same immunity approach is used across installation types.
The document is organized in a practical test-oriented way:
- Clause 1 states the scope.
- Clause 2 lists normative references.
- Clause 3 gives terms, definitions, and abbreviations.
- Clause 4 explains applicability.
- Clause 5 sets the test conditions.
- Clauses 6 to 11 cover the individual immunity phenomena.
- Annex A gives the criteria for operation as intended.
- Annex B gives guidance for that assessment.
- Annex ZZ links the standard to Directive 2014/30/EU.
| Annex | What it covers |
|---|---|
| Annex A | Criteria for operation as intended |
| Annex B | Guidance for assessing operation as intended |
| Annex ZZ | Relationship to Directive 2014/30/EU |
What are the key requirements of prEN 50130-4:2026?
General test approach and setup
prEN 50130-4:2026 treats the immunity checks as separate tests, and each test has to meet its own compliance criteria. If several tests are run on one sample, the order is optional, but the final assessment has to show the equipment still works as intended after the last test.
Clause 4 and Clause 5 make the setup requirements very practical:
- the EUT has to be configured as it would be in service, with relevant power, monitoring, loading, and auxiliary equipment connected;
- enough inputs and outputs have to be exercised to cover the different types of interfaces;
- cable type, length, termination, and port identification have to be recorded;
- if the product manual calls for external protection measures, the tests are done with those measures in place.
This matters because the immunity result should reflect the real installation, not an artificial lab-only setup.
Environmental and operating conditions
prEN 50130-4:2026 uses the standard atmospheric conditions from EN 60068-1 unless a basic EMC standard or the test procedure says otherwise. Each test is run at one set of parameters and at rated supply voltage, unless the document states something different.
The EUT has to be monitored during testing so that status changes, outputs, or alarm states can be detected. If the test makes the EUT dangerous or unsafe, the EUT is treated as having failed.
Performance criteria
Clause 5 separates performance criteria into two groups:
- continuous phenomena - radiated electromagnetic fields and conducted disturbances induced by electromagnetic fields;
- transient phenomena - supply dips and interruptions, electrostatic discharge, fast transient bursts, and slow high energy voltage surge.
For continuous phenomena, the EUT must not make an unintentional change of operating mode, and critical stored data should not change unintentionally. For transient phenomena, the same principle applies after the test: the EUT must still operate as intended, and Annex A is used to check that.
A useful practical point is that temporary deterioration of a video picture can be acceptable if the threat can still be detected. That matters for video surveillance equipment where a brief degradation is not the same as loss of the security function.
Clauses 6 to 11: the immunity tests
Clause 6 covers mains supply voltage dips and short interruptions on AC mains ports. Temporary loss of function can be acceptable during a full interruption if the EUT recovers without operator intervention, with no damage, malfunction, or unintended status change.
Clause 7 covers electrostatic discharge. Contact, air, direct, and indirect discharges are applied according to the installation and accessibility of surfaces. Brief indicator flicker is acceptable if it does not leave a residual change or output change.
Clause 8 covers radiated electromagnetic fields. The test includes amplitude-modulated fields, and some equipment, such as motion detectors and flame detectors, also gets pulse-modulated exposure. The cabling arrangement is especially important here, so the report has to document cable layout carefully.
Clause 9 covers conducted disturbances induced by electromagnetic fields on signal and supply lines. Motion detectors and flame detectors again receive additional pulse-modulated exposure. The clause also allows some ports to be excluded when the manufacturer limits connected cable length to a stated maximum.
Clause 10 covers fast transient bursts on AC mains, DC distribution networks, and signal lines. The clause states when the test is not required for short-cable ports, and it allows indicator flicker if the equipment does not show a residual change.
Clause 11 covers slow high energy voltage surge on mains, other supply and signal lines, and shielded lines. It sets different coupling cases for different line types and notes when ports with a documented cable-length limit can be excluded. If the coupling network affects operation, the EUT is checked again without the network for loss of data or damage.
Reporting and exceptions
Clause 5.4 requires a test report that contains enough information to reproduce the test. The report has to record the primary-function assessment method and result, and it has to explain any clause that was not applicable because of the nature of the EUT. That is important for audits, supplier acceptance, and conformity evidence.
What terms does prEN 50130-4:2026 define?
- EUT - Equipment Under Test: the equipment being checked for immunity.
- EMC - Electromagnetic Compatibility: the ability of equipment to operate without unacceptable disturbance in its electromagnetic environment.
- CW - Continuous Wave: an unmodulated carrier used as the basis for some field and conducted tests.
- CDN - Coupling Decoupling Network: the network used to inject conducted disturbances while separating the test setup from unwanted interference.
- VSS - Video Surveillance System: a system of camera, storage, monitoring, and associated transmission or control equipment.
- Primary function: the intended function of the safety or security component, such as detection, signalling, transmission, or access control.
- Response time: the time a system needs to react to a stimulus such as an alarm or fault.
- Signal line: a line used for signalling, communication, or power that is not meant to connect to an AC or DC distribution network.
Who uses prEN 50130-4:2026?
prEN 50130-4:2026 is used by manufacturers of alarm and security equipment, EMC test laboratories, certification and conformity teams, and system integrators. It is also relevant to quality managers and buyers who need to specify immunity expectations for products used in security, fire, and social alarm applications.
In practice, it is used when designing products, planning type tests, preparing test reports, and checking whether equipment still performs its primary function after immunity exposure. Annex ZZ also makes it relevant for anyone working with the EMC requirements of Directive 2014/30/EU.
What changed in prEN 50130-4:2026 from the previous edition?
prEN 50130-4:2026 supersedes EN 50130-4:2011 and EN 50130-4:2011/A1:2014. The foreword states these significant technical changes:
- the title was changed;
- the referenced base standards were updated to the latest versions;
- the test methods and/or requirements in Clauses 8 and 11 were changed.
The foreword also states that equipment meeting this edition is deemed to meet EN 50130-4:2011.
Which standards are used with prEN 50130-4:2026?
The standard relies on several basic EMC and environmental test standards:
- EN 60068-1 - gives the environmental test conditions.
- EN IEC 61000-4-2 - provides the ESD test method.
- EN IEC 61000-4-3 - provides the radiated RF field immunity test method.
- EN 61000-4-4 - provides the fast transient burst test method.
- EN 61000-4-5 - provides the surge test method.
- EN IEC 61000-4-6 - provides the conducted RF immunity test method.
- EN IEC 61000-4-11 - provides the voltage dip and short interruption test method.
The foreword and bibliography also point to companion product standards that cover other performance requirements for the same application areas:
- EN 50131
- EN 50134
- EN 50136
- EN 54
- EN 60839-11
- EN 62676
What does the prEN 50130-4:2026 document contain?
The standard contains the test philosophy, applicability rules, environmental and configuration requirements, and the pass/fail logic for EMC immunity testing. It also includes the specific test clauses for supply dips, electrostatic discharge, radiated fields, conducted disturbances, fast transients, and surge.
Annex A gives the practical criteria used to judge whether the primary function still works as intended. Annex B gives examples of how to assess that result for different alarm and security functions. Annex ZZ provides the legal traceability to Directive 2014/30/EU for EMC immunity.

4 Applicability
The tests shall be carried out as single tests, as described in the later clauses, and the EUT shall meet the
criteria for compliance for each test. If several tests are made on a single example of the EUT, the sequence
of testing is optional, and it is permissible to substitute or omit intermediate assessments of the performance
of the EUT, provided that the assessment of the performance of the EUT is conducted after the last test.
NOTE If intermediate assessments of the performance of the EUT are substituted or omitted and a failure occurs, it
might not be possible to identify which test exposure caused the failure.
The tests and severities shall be the same for indoor and outdoor applications of fixed, movable and portable
equipment.
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 document.
Where test clauses are not applicable due to the nature of the EUT, this shall be recorded in the test report,
along with a justification.
5 Conditions during testing
5.1 Configuration
The EUT shall be connected to a suitable power supply, monitoring and loading equipment. If the EUT is part
of a system, or can be connected to auxiliary equipment, then the EUT shall be tested while connected in a
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.
In cases where a EUT specification requires external protection devices or measures which are clearly
specified in the user's manual, the test requirements of this document shall be applied with the external
protection devices or measures in place.
The EUT shall be tested in an operation mode that permits examination of the criteria for compliance of this
document for each test. The configuration of the test sample shall be chosen to achieve maximum
susceptibility and shall be representative of its intended use. The configuration and mode of operation during
the tests shall be precisely noted in the test report.
During testing, 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.
Each test shall be carried out at one single set of parameters within the environmental conditions in 5.2 and at
the rated supply voltage of the EUT, unless otherwise indicated in this document.
If, as a result of the application of the tests defined in this document, the EUT becomes dangerous or unsafe,
it shall be deemed to have failed the test.
5.2 Environmental conditions
Unless otherwise indicated in the basic EMC standard or test procedure, the tests shall be carried out within
the following standard atmospheric conditions for measurements and tests, as specified in EN 60068-1:2014,
4.3:
— temperature: 15 °C to 35 °C;
— relative humidity: 25 % to 75 %;
— air pressure: 86 kPa to 106 kPa.
5.3 General performance criteria
5.3.1 Introduction
The performance criteria are used to take a decision on whether the EUT passes or fails immunity tests. For
the purpose of the present document two categories of performance criteria apply:
a) Performance criteria for continuous phenomena. Continuous phenomena are
— radiated electromagnetic fields;
— conducted disturbances induces by electromagnetic fields.
b) Performance criteria for transient phenomena. Transient phenomena are
— main supply voltage dips and short interruptions;
— electrostatic discharge;
— fast transient bursts;
— slow high energy voltage surge.
If, as a result of the application of the tests defined in this document, the EUT becomes dangerous or unsafe,
it shall be deemed to have failed the test.
5.3.2 Performance criteria for continuous phenomena
Unless otherwise indicated in this document, the criteria for compliance with tests for continuous phenomena
shall be:
— During application of the phenomena, the EUT shall not result in an unintentional change of the mode of
operation (e.g. signal alarm or fault).
— There should be no unintentional change of critical stored data as a result of the application of the
phenomena.
— For EUTs with the primary function of providing a video picture for monitoring a potential threat situation,
a temporary self-recovering deterioration of the picture is allowed, providing that the deterioration to the
video picture allows to detect a potential threat.
After application of the continuous phenomena the EUT shall operate as intended. This shall be verified by an
assessment of the expected performance of the primary function(s) according to Annex A.
NOTE If the EUT operates as intended after the application of the continuous phenomena it can be seen as proof
that no critical stored data were unintentional changed.
It is recommended to assess the performance of the primary function before application of the test to be able
to detect any deterioration of the primary function after the test.
5.3.3 Performance criteria for transient phenomena
Unless otherwise indicated in this document, the criteria for compliance with tests for transient phenomena
shall be:
— The application of the transient phenomena shall not result in the unintentional change of critical stored
data or an unintentional change of the mode of operation (e.g. signal alarm or fault) after the completion
of the test.
— After application of the transient phenomena the EUT shall operate as intended. This shall be verified by
an assessment of the expected performance of the primary function(s) according to Annex A.
NOTE If the EUT operates as intended after the application of the continuous phenomena it can be seen as proof
that no critical stored data were unintentional changed.
It is recommended to assess the performance of the primary function before application of the test to be able
to detect any deterioration of the primary function after the test.
