12、ction and alarm systems. It should be read in conjunction, where appropriate, with the following British Standards: In view of the increasing use of integrated systems, it is important that a code of practice be provided for designers, installers, service organizations and users. This code therefore
13、 is intended to assist interested parties in acquiring a better understanding of the complexity of such systems and to ensure that the overall integrity is at least as good as the integrity of the individual systems that are replaced. The code aims to: a) provide a common basis of standards to recog
14、nize technical advances in the development of both integrated systems and sub-systems which may not yet be reflected in individual regulations, standards and codes of practice; and b) ensure that the highest standards of security, safety and reliability are achieved where systems have been integrate
15、d. NOTENational, European and international standards, regulations and codes of practice may apply individually to each of the functions included within an integrated system. These standards may cite different requirements which may conflict. It is intended that, after consideration by interested pa
16、rties, this code of practice may ultimately be used by standards-making bodies to assist in resolving any such conflicts. As a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be t
17、aken to ensure that claims of compliance are not misleading. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from
18、 legal obligations. In particular, attention is drawn to BS 7671 Requirements for electrical installations. IEE Wiring Regulations. BS 4737-4Intruder alarm systems. Codes of practice BS 5839-1Fire detection and alarm systems for buildings. Code of practice for system design, installation and servici

22、ound buildings other than dwellings. The recommendations relate to the specification, design, installation, commissioning, hand-over and maintenance of such integrated systems, and to the users responsibilities for operating and testing them. NOTEVarious configurations of integrated system are class
23、ified, with conceptual examples, in Annex A. 2 Normative references This British Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are made at the appropriate places in the text and the cited publications are listed on inside back co
24、ver. For dated references, only the edition cited applies; any subsequent amendments to or revisions of the cited publication apply to this British Standard only when incorporated in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies,
25、together with any amendments. 3 Definitions 3.1 security system a fire alarm system, an intruder alarm system, a hazard warning system or any other system intended for the protection of life and/or property 3.2 non-security system a system intended to provide environmental or management control and

33、k of inspection, servicing and repair necessary for the continuing efficient operation of the installed system 3.12 expert system a system of hardware and software using a database of human expertise for problem solving 3.13 user a person authorized to operate the system 4 Quality 4.1 All phases of
34、the establishment of the integrated system should be undertaken within a quality management system commensurate with the significance of the relevant sub-system. Particular attention should be paid to those elements of the integrated system which directly affect the functionality and reliability of
35、security sub-systems. 4.2 The major phases for consideration are: a) system specification; b) system and product design; c) manufacturing; d) installation; e) commissioning; f) hand-over; g) maintenance. 4.3 Quality management systems should at least conform to relevant standards of the BS EN ISO 90
36、00 series. NOTEIndividual sub-systems may have particular quality requirements specified within relevant standards for product and system approvals or certification. 4.4 In considering potential installers, consideration should be given to the status of the installing company, and in particular to w
37、hether its work is subject to technical inspections by a third party. 5 Design 5.1 General A design controller should be appointed, having responsibility for the design of the complete system. 5.2 Design concepts It is likely that a number of organizations will be involved in the design, installatio
38、n and servicing of integrated systems. The organization responsible for the building may appoint persons with specific responsibilities for security systems and others with responsibilities, for example, for building management systems. The responsibilities, terms and requirements of each of the org
39、anizations should be clarified, documented and fully considered before system design and installation is undertaken. All references in this standard to the requirements of the system refer to minimum requirements and the designers of such systems should take into account the nature of the premises,
40、the value of its contents, the degree of risk and any other factors which may influence the choice and content of the system. Consideration should be given to the means of communicating with people and organizations, both on and off site, who are involved in responding to emergencies. The security a
41、nd integrity of the method of communication should be commensurate with the type of risk. The alarm organization plan should be suitably detailed to cover all foreseeable eventualities. Aspects to be considered should include: a) the level of risk and any risk classification (if appropriate); b) the
42、 number and location of in-house personnel to be summoned in the event of an alarm condition; c) the methods of communication employed: for example, pocket pagers and voice messages; d) the appropriate in-house response at various times of the day and night; e) who is responsible for ensuring that c
43、orrect actions are taken at various times of the day and night; f) who is responsible for ensuring that faults or failures in any part of the system are rectified. Any form of automatic transmission of signals should clearly discriminate as to the nature of the event being signalled (see 5.8). Appro
44、priate third parties should be consulted (for example, the insurer, police, fire service, local authorities, architects and suppliers of utilities to the building). System design should take into account the requirements of all applicable standards (see Annex B). Licensed Copy: London South Bank Uni

46、perational procedures that apply in the event of an alarm fault or status signal and the nature of the personnel who use the system. Controls and indications forming part of the integrated system should meet the relevant requirements of applicable British Standards. For example, systems monitoring f
47、or fire should conform at least to BS 5839-4 and should be designed, installed and serviced in accordance with the recommendations of BS 5839-1. The correct allocation of priorities of information presented by the integrated system in an alarm situation is crucial in ensuring that the most appropria
48、te sequence of actions is taken at the earliest possible time. In view of this, it is important that early consultation be undertaken with all interested parties (see 5.2), in order to determine the most appropriate priority for each of the functions. Similarly, it may be necessary to prioritize the
49、 fault indications or other warnings to ensure that their effects on the functionality of the system are minimized. Information should be prioritized and displayed in a planned, clear and unambiguous manner, to minimize the possibility of information being misread or misinterpreted. All possible scenarios, and their likely consequences, should be considered in determining the output priorities. Interactions between the functions may result in enhanced overall performance and thus should also be considered, together with additional factors such as those identified i
