12、controlled Copy, (c) BSI ii BSI 10-1999 BS 5266-1:1999 Foreword This part of BS 5266 has been prepared by Technical Committee CPL/34/9. Together with BS EN 1838, it supersedes BS 5266-1:1988, which is withdrawn. This new edition of BS 5266-1 has been produced to take into account the requirements of
13、, and remove any requirements which conflict with, BS EN 1838. The other parts of this standard are: Part 2: Code of practice for electrical low mounted way guidance systems for emergency use; Part 3: Specification for small power relays (electromagnetic) for emergency lighting applications up to an
14、d including 32A; Part 4: Code of practice for design, installation, maintenance and use of optical fibre systems; Part 5: Specification for components parts of optical fibre systems; Part 6: Code of practice for non-electrical low mounted way guidance systems for emergency use Photoluminescent syste
15、ms; Part 7: Lighting applications Emergency lighting. (Also numbered BS EN 1838) The aim of this code is to promote wider understanding of the different types of emergency lighting system which may be employed and to give guidance on their correct application to the varied requirements of different
16、categories of premises. The recommendations given in this code of practice have been drawn up to encourage uniformity of application, based on providing adequate safety to persons in the event of interruption of the normal lighting and having due regard to the hazard level and degree of familiarity
17、of occupants with particular premises. The code recognizes that in addition to ensuring safe unobstructed means of escape from the premises at all times, an important function of emergency lighting is to make possible the immediate location and operation of fire alarm points and fire fighting equipm
18、ent and another is to minimize the chance of panic arising in enclosed spaces, such as lifts. Although the code makes recommendations for the provision of emergency lighting in a wide variety of premises, the fact that particular types of premises are mentioned in clause 9 does not necessarily mean
19、that all such premises will be required by law to have emergency lighting installed. For certain classes of premises the provisions of this code may be supplemented or replaced by alternative requirements at the discretion of the enforcing authority. A British Standard does not purport to include al
20、l 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 legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and
21、 ii, pages 1 to 24, an inside back cover and a back cover. The BSI copyright notice displayed in this document indicates when the document was last issued.

22、his part of BS 5266 relates to the provision of electric emergency lighting in most types of premises, other than private domestic premises, cinemas and existing premises to which the provisions of CP 1007, covering maintained lighting for cinemas, have been applied by the enforcing authority. Premi
23、ses not covered are those used primarily as: ballrooms and dance halls; cinemas licensed under the Cinemas Act 1985; bingo premises licensed under the Gaming Act 1968 as amended by the Gaming (Amendment) Act 1982; ten-pin bowling establishments. Although the code does not cover private domestic prem
24、ises, its provisions are applicable to common access routes within multistorey dwellings. This code no longer covers the levels of illumination required as these are dealt with in BS EN 1838. References to BS EN 1838 are made throughout the text. The code gives recommendations for the indication and
25、 illumination of escape routes in the event of failure of the normal supply, and proposes minimum continuous periods of operation of such emergency lighting based on the size, type and usage of the premises. NOTE 1Should it be necessary to apply the code to any other type of lighting, the exact way
26、in which each of its provisions is to be met should be the subject of agreement with the enforcing and/or other relevant authority before work is started. NOTE 2The titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this par
27、t of BS 5266 the following definitions apply. 2.1 combined (sustained) emergency luminaire an emergency lighting luminaire containing at least two lamps, one of which is energized from the normal lighting supply and the other from an emergency lighting supply. Such a luminaire is intended to sustain
28、 illumination at all material times 2.2 duration the period of time that the luminaire can continuously provide the minimum illuminance required in the emergency condition. The time is specified in hours 2.3 emergency exit an exit which is intended to be used only during an emergency 2.4 emergency l

In addition to the recommendations of this code it is important that the requirements of any national and/or local legislation which may apply to the premises in question are fully recognized and discussed at this time. 3.2 Supply of plans Plans showing the layout of the building and of
44、all existing or proposed escape routes, fire alarm call points and fire fighting equipment and indicating the positions of all items, structural or otherwise, which may offer obstruction to escape, should be provided at an early stage for use during the consultations referred to in 3.1. 3.3 Records
45、On completion of the work, drawings of the emergency lighting installation should be provided and retained on the premises. Such drawings should be regularly updated to keep them in line with any subsequent changes to the system. In addition, and in accordance with 11.3, a log book should be provide
46、d for the recording of routine examinations, tests, defects and alterations. A manual of operation and maintenance should be handed to the occupier. Recommendations on the measuring of illuminance of emergency lighting are given in annex A. Licensed Copy: sheffieldun sheffieldun, na, Fri Dec 01 14:1

Throughout this code reference to emergency lighting covers escape lighting in particular, b
48、ut also includes any element of standby lighting which may be used for escape lighting. 4.2 Escape lighting When the supply to the normal lighting or parts of the normal lighting to occupied premises fails, escape lighting is required to fulfil the following functions: a) to indicate clearly and una
49、mbiguously the escape routes; b) to provide illumination along such routes to allow safe movement towards and through the exits provided; c) to ensure that fire alarm call points and fire fighting equipment provided along escape routes can be readily located. Escape lighting is required not only on complete failure of the supply to the normal lighting but also on a localized failure if such a failure would present a hazard, e.g. a single subcircuit on stairways.
