124 This document will supersede EN 50131-3:2009 and all of its amendments and corrigenda (if any).
125 prEN 50131-3:2025 includes the following significant technical changes with respect to EN 50131-3:2009:
126 — refined and aligned requirements to EN 50131-1:2006 ;
127 — refinement and clarification of test section;
128 — clarified and refined the use of distributed components with a CIE;
129 — Annex A has been expanded to include the topology of the CIE;
130 — Annex C has been re-written to expand on the use of non-I&HAS interfaces over an indirect connection;
131 — Annex D has been added to cover the use of non-I&HAS interfaces over a direct connection.

As impacted by EN 50131-1:2006/A1:2009, EN 50131-1:2006/A2:2017 and EN 50131-1:2006/A3:2020.
132 Introduction
133 Repetition of definitions and requirements contained in EN 50131-1 have been eliminated from this EN 50131-3,
134 in order to minimize conflict in the event of changes to EN 50131-1, except where repetition is deemed essential
135 for the clarity of this document.
136 Reference has been included to various implications arising from the detector standards. Full detail of the
137 interconnection requirements could be the subject of a future standard.
138 A number of requirements are contained in this document for which a formal test procedure can only be written
139 by defining (and hence restricting) the technology by which the requirement is achieved. Accordingly, it has
140 been recognized that such functions can be tested only by agreement between manufacturer and test house,
141 according to documented information relating to how the required functionality has been achieved.
142 In Annex E a table has been included to cross reference EN 50131-1 requirements against this document and
143 tests.
144 1 Scope
145 This document specifies the requirements, performance criteria and testing procedures for control and indicating
146 equipment (CIE) intended for use in intrusion and hold-up alarm systems (I&HAS) installed in buildings. This
147 document also applies to CIE to be used in IAS or HAS.
148 The CIE can incorporate processing functions of other I&HAS components or its processing requirements can
149 be distributed among such components.
150 This document specifies the requirements for CIE installed in buildings using specific or non-specific wired
151 interconnections or wire-free interconnections. These requirements also apply to basic DCC which can be
152 installed outside of the supervised premises and mounted in indoor or outdoor environments.
153 Where CIE shares means of detection, interconnection, control, communication, processing and/or power
154 supplies with other applications, these requirements apply to I&HAS functions only.
155 This document specifies performance requirements for CIE at each of the four security grades identified in
156 EN 50131-1. Requirements are also specified for four environmental classes covering applications for indoor
157 and outdoor locations.
158 This document includes mandatory functions for all CIE for the appropriate security grade, as well as optional
159 functions that can additionally be provided.
160 This document does not cover requirements for compliance with EU regulatory Directives, such as the EMC
161 Directive, Low Voltage Directive, etc. except in that it specifies the equipment operating conditions for EMC
162 susceptibility testing as required by EN 50130-4.
163 NOTE 1 In this document reference to the term “I&HAS” is used throughout, except where there is specific need to
164 differentiate between the IAS and HAS portions of a system. The term is intended to include IAS and HAS when such
165 systems are installed separately.
166 NOTE 2 For products which integrate functions from, and which the manufacturer is claiming compliance to, several
167 EN 50131 standards, the requirements of this document apply as well as any additional requirements from other relevant
168 EN 50131 standards (e.g. a CIE with integral Warning Device is expected to meet the requirements of EN 50131-3 and
169 EN 50131-4).

331 4 Equipment attributes
332 4.1 General
333 CIE shall include attributes for the reception of signals and/or messages, processing the information, notification
334 and indication as appropriate. The detailed requirements are provided in Clause 8.
335 If a function is provided that is optional for a particular grade and a claim of compliance is made, it shall meet
336 the applicable requirements for the grade for which compliance is claimed (if any are given). If there are no
337 specifications for the function at the grade in question, the requirements for any higher grade (as identified by
338 the manufacturer) shall apply.
339 Compliance with this document shall be demonstrated by assessment of Clause 4 through to Clause 10 and
340 the application of the tests of Clause 11.
341 Annex D provides a cross reference between the requirements of EN 50131-1 and the requirements and tests
342 of this document.
343 CIE which include the coerciveness principle in accordance with EN 50131-1:2006, 8.8.2.2 shall comply with
344 the requirements, and meet the tests, of CLC/TS 50131-12.
345 4.2 Functionality
346 Functions additional to the mandatory functions specified in this document may be included in I&HAS providing
347 they do not influence the correct operation of the mandatory functions.
348 Where provided, these additional functions shall not affect compliance with the requirements of this document,
349 except as permitted by EN 50131-1:2006, 8.3.13.
350 If use of a function(s) or combination of functions within the CIE would result in the installed I&HAS not being
351 compliant with EN 50131-1 or being compliant at a lower security grade (e.g. function(s) reducing the security
352 of the I&HAS) the manufacturer shall, either:
353 a) detail the configuration(s) which are compliant with EN 50131-1;
354 or
355 b) detail the function(s) or combination of functions that would result in the installed I&HAS not being compliant
356 with EN 50131-1.
357 A non-I&HAS interface may be used to carry out CIE functions if the conditions specified in Annex C or D are
358 met. A non-I&HAS interface shall not be the only means of providing mandatory functions of the CIE.
359 5 CIE topology
360 The CIE may be in a single housing or be distributed across multiple DCCs.
361 If the CIE is distributed in multiple DCCs, these collectively achieve the CIE functions described in this
362 document.
363 NOTE Annex A shows an example of how DCCs combine to form the CIE.
364 CIE or DCC may be combined with other I&HAS components.
365 6 Security grade
366 Any CIE or DCC shall meet the relevant requirements for one of four security grades for which it is declared to
367 comply. The grade of a CIE shall be that of the lowest graded component. The CIE shall meet all the
368 requirements of that grade.
369 The requirements for the performance of the CIE will vary depending upon its grade. Any testing will be carried
370 out according to the grade declared in the CIE documentation and marking.
371 7 Environmental performance
372 7.1 Requirements
373 Any CIE or DCC shall be suitable for use in at least one of the environmental classes defined in EN 50131-1.
374 When the requirements of the four environmental classes are inadequate, due to the extreme conditions
375 experienced in certain geographic locations, special national conditions are given in EN 50131-1:2006,
376 Annex A.
377 7.2 Environmental and EMC tests
378 EN 50130-4 specifies EMC susceptibility tests relevant to I&HAS components. The operating conditions for
379 these tests are specified in Table 32.

386 hold-up trigger devices and information from user input devices as specified in the following subclauses.
387 NOTE 1 This document does not specify details of interconnections or the format of these signals or messages. Details
388 of possible means of transfer of the information are included in some of the component standards within the EN 50131
389 series.
390 NOTE 2 Some system components can require up to 180 s to initialise before normal functionality is available, (e.g.
391 detectors).
392 8.1.1 Intruder detection
393 The CIE shall provide the means to receive signals or messages from intruder detectors.
394 8.1.2 Hold-up device
395 When a CIE provides hold-up facilities, means shall be provided to receive signals or messages from hold-up
396 devices.
397 8.1.3 Tamper
398 The CIE shall provide the means to receive tamper signals or messages.
399 8.1.4 Fault
400 Dependent on the grade, CIE shall include means to recognize the fault conditions as specified in
401 EN 50131-1:2006, Table 1 and in addition those faults shown in Table 1.

403 8.1.5 User input
404 The CIE shall provide the means for user input in order to operate the I&HAS.
405 EXAMPLE a keypad
406 8.1.6 Masking
407 The CIE shall provide the means to receive masking signals or messages, according to grade.
408 8.1.7 Non-I&HAS inputs
409 When a CIE receives signals or messages or other information not necessary to meet the requirements of this
410 document (e.g. monitoring of non-I&HAS equipment) this shall not affect the ability of the CIE to meet the
411 requirements of this document.
412 8.2 Outputs
413 Notification output requirements are detailed in 8.6
414 The CIE may need to provide output signals or messages to interface with other I&HAS components, as required
415 by other relevant component standards. The installation documentation shall identify which configurations are
416 available.
417 EXAMPLES
418 a)  indication enable for detector or other component;
419 b)  set/unset status information for detector, security fog device, etc.;
420 c)  to trigger audible or visual alarm confirmation equipment;
421 d)  to trigger security fog devices, etc.;
422 e)  to enable functional test mode of detector;
423 f)  to trigger remote self-test of detector or other component;
424 g)  to restore detectors or other devices.
425 If the restore involves removal of power from detectors, up to 180 s should be allowed for the detector to resume
426 normal operation (see EN 50131-2-series).
427 Output signals or messages may additionally be provided to interface to equipment outside of the I&HAS.
428 EXAMPLE lighting
429 8.3 Operation
430 The CIE shall provide the means necessary to enable authorized users to access the functions of the CIE.
431 Access to these functions shall be restricted by access levels and corresponding authorisations according to
432 8.3.1 and 8.3.2.
433 EXAMPLE by using a keypad or lock
434 8.3.1 Access levels
435 Access to the functions of a CIE shall be restricted according to the requirements of EN 50131-1:2006, 8.3.1. If
436 the CIE includes security functions additional to those identified in EN 50131-1:2006, Table 2 the access levels
437 necessary to operate those functions shall be specified by the manufacturer. Access levels for any non-security
438 functions shall be specified in the manufacturer’s documentation.
439 Access at level 3 shall be authorized by access level 2 such that:
440 a) access remains authorized until manually removed,
441 or
442 b) access requires authorization for each occasion it is used.
443 Access at level 4 shall be authorized by access level 2 and 3 for each occasion it is used.
444 If level 3 access is granted without level 2 authorization, as permitted by EN 50131-1:2006, 8.3.1, the internal
445 warning device shall be time limited, either to a fixed time quoted by the manufacturer or until silenced by the
446 level 3 user.
447 8.3.2 Authorization
448 8.3.2.1 Access to functions
449 Access to the functions of a CIE at levels 2, 3 and 4 shall be restricted as required by EN 50131-1:2006, 8.3.2.
450 Authorization is not required for access at level 1.
451 At least one of the methods in 8.3.2.2 or 8.3.2.3 shall be provided by the CIE.
452 Authorization shall be validated by the CIE.
453 If means to provide temporary authorization is provided (e.g. a PIN code valid for a limited time or valid for use
454 a specified number of times), details should be included in the manufacturer’s documentation.
