Emergency escape lighting systems
This European Standard specifies the provision and illumination of escape routes and safety signs in the event of failure of the normal supply, and specifies the minimum provision of such emergency lighting based on the size, type and usage of the premises. This standard relates to the provision of electric emergency escape lighting in all work places and premises open to the public. This European Standard does not cover private domestic premises but its provisions are applicable to common access routes within multi-storey dwellings. This European Standard is also applicable to standby lighting used as emergency escape lighting. There are emerging way guidance techniques that, when applied to escape routes in addition to conventional emergency lighting luminaires, can enhance its effectiveness in an emergency.
Sicherheitsbeleuchtungsanlagen
Diese Europäische Norm legt die Kennzeichnung von Rettungswegen und die Anforderungen der Beleuchtung an Rettungswege bei Störung der allgemeinen Stromversorgung sowie die Mindestanforderung einer solchen Sicherheitsbeleuchtung je nach Größe, Art und Nutzung der baulichen Anlage fest. Diese Norm betrifft die Festlegung einer elektrischen Sicherheitsbeleuchtung an allen Arbeitsplätzen und anderen baulichen Anlagen für Menschenansammlungen.
Diese Europäische Norm bezieht private Wohnhäuser nicht ein, ihre Bestimmungen müssen aber für öffentlich zugängliche Wege innerhalb von Wohnhochhäusern angewandt werden.
Diese Europäische Norm gilt auch für Ersatzbeleuchtung, wenn diese als Sicherheitsbeleuchtung benutzt wird.
Es gibt Techniken für Sicherheitsleitsysteme, die die Wirksamkeit im Notfall erhöhen können, wenn sie in Rettungswegen zusätzlich zu herkömmlichen Leuchten der Sicherheitsbeleuchtung eingesetzt werden.
Systèmes d'éclairage de sécurité
La présente Norme Européenne donne les prescriptions pour la signalisation et l’éclairage des voies d’évacuation en cas de défaillance de l’alimentation normale, et définit les besoins minimaux pour l’éclairage de sécurité en fonction de la taille, du type et de l’utilisation des locaux. La présente norme traite de l’éclairage de sécurité dans les locaux recevant des travailleurs et dans les locaux recevant du public.
Cette Norme Européenne ne couvre pas les locaux d’habitation privés, mais ses prescriptions sont applicables aux circulations communes des immeubles d’habitations à plusieurs étages.
Cette Norme Européenne s’applique aussi à l’éclairage de remplacement dans le cas où il est utilisé comme éclairage de sécurité.
De nouvelles techniques de guidage existent qui utilisées en complément des luminaires conventionnels de sécurité dans les voies d’évacuation peuvent augmenter leur efficacité pendant une évacuation.

4 Emergency escape lighting
4.1 General
The purpose of emergency escape lighting is to ensure the lighting is provided promptly, automatically
and for a suitable time in a specified area when the normal power supply to the normal lighting fails. The
installation shall ensure that emergency escape lighting fulfils the following functions:
a) to illuminate escape route signs;
b) to provide illumination onto and along such routes as to allow safe movement towards and through
the exits provided to a place of safety;
c) to ensure that fire alarm call points and fire equipment provided along escape routes can be readily
located and used;
d) to permit operations concerned with safety measures.
Emergency escape lighting shall be activated not only on complete failure of the supply to the normal
lighting but also on a localized failure such as a final circuit failure.
Emergency escape lighting is not designed to enable normal operations to be continued on the premises
in the event of failure of normal or standby lighting.
Full details of levels and measurement of illuminance and adaptation are specified in EN 1838 and
EN 13032.
The wiring rules of HD 384 / HD 60364 shall be complied with.
4.2 Identification and luminance of emergency exit signs
Where direct sight of an exit is not possible and doubt may exist as to its location, a directional sign (or
series of signs) shall be provided, placed such that a person moving towards it will be directed towards an
emergency exit.
An exit or directional sign shall be in view at all points along the escape route.
All signs marking exits and escape routes shall be uniform in colour and format, and their luminance shall
comply with EN 1838.
NOTE Maintained exit signs should be considered for applications where occupants may be unfamiliar with the building.

4.3 Escape route lighting
The objective of escape route lighting is to enable safe exit for occupants by providing appropriate visual
conditions and direction finding on escape routes and to ensure that fire fighting and safety equipment
can be readily located and used.
4.4 Open area (anti-panic) lighting
The objective of open area (anti-panic) lighting is to reduce the likelihood of panic and to enable safe
movement of occupants towards escape routes by providing appropriate visual conditions and direction
2
finding. It is used in areas of undefined escape routes in halls or premises larger than 60 m floor area or
smaller areas if there is additional hazard such as use by a large number of people.
NOTE Condition BD3 or BD4 of HD 384 also defines areas that require emergency lighting.
4.5 Emergency lighting for high risk task area lighting
The objective of high-risk task area lighting is to ensure the safety of people involved in a potentially
dangerous process or situation and to enable proper shut down procedures for the safety of other
occupants of the premises.
4.6 Standby lighting
If standby lighting is used to provide emergency escape lighting, the installation shall comply with the
provisions of this standard and the appropriate product and wiring standards.
5 Emergency escape lighting system design
5.1 Plan of premises
In order to ensure that the emergency lighting system is engineered in accordance with EN 1838 plans
showing the layout of the building and of all existing or proposed escape routes, fire alarm call points and
fire fighting equipment and indicating the positions of all structural items which may offer obstruction to
escape shall be provided before commencing system design.
5.2 Failure of normal supply to part of premises
Emergency escape lighting shall operate, in the event of failure of any part of the normal lighting supply.
Non-maintained and combined non-maintained emergency luminaires have to operate in the event of
failure of a normal lighting final circuit. In all cases, arrangements shall be made to ensure that local
emergency escape lighting will operate in the event of failure of normal supply to the corresponding local
area.
5.3 System integrity
The provision of highly reliable emergency escape lighting is essential. The illumination by the emergency
escape lighting system of a compartment of the escape route shall be from two or more luminaires so that
the failure of one luminaire does not plunge the route into total darkness or make the directional finding
effect of the system ineffective. For the same reason, two or more luminaires shall be used in each open
area (anti-panic).
