Introduction
When the electricity supply fails and the lights go out, it is essential that emergency lighting is
automatically activated to provide adequate illumination for normal activities to continue and for
the safe evacuation of the building. Instant illumination is required when the supply fails and for this
reason only, fluorescent or tungsten light sources are used.
Emergency lighting is demanded mainly because of legislation. This legislation itself is a direct result
of public and political pressure to safeguard life and to ensure uniform standards in places where
the public gather.
The existing U.K. legislation for emergency lighting, BS 5266:1999, has been partially superseded
by BS EN 50172:2004, and is currently under review to remove any conflicts with this European
Directive. Consideration given now to the standards which the Directives evoke, will provide
substantial savings in the future.
BS 5266: 1999 gives a ‘standards tree’ for the different types of emergency lighting covered, and a
definition for each form of lighting.
Standby Lighting
This is the part of emergency lighting which may be provided to enable normal activities to continue
in the event of failure of the normal mains supply. For long back-up periods (in excess of three hours),
it is normal for central battery systems, uninterruptible power supplies or standby generators to be used.
Escape route lighting
Emergency Escape Lighting
This is the part of emergency lighting which is provided to ensure all means of escape can be safely and effectively used at all times. Emergency
escape lighting may be subdivided into three areas:
1 Escape Route Lighting
The emergency lighting on a route forming part of the means of escape from a point in a building to final exit.
2 Open Area (Anti-panic) Lighting
The part of emergency lighting provided to avoid panic and provide illumination allowing people to reach a place where an escape route can
be identified.
3 High Risk Area Lighting
A new category provided 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 the operator. The full responsibilities of the Owner/Occupier are detailed within the new Regulatory Reform Fire Safety
Order* (RRO) which will replace the majority of existing laws within the UK during 2005/6.
To ensure the system is well designed and as reliable as possible, Gent stresses the importance of planning through all the phases of the project,
from considering legal requirements to final commissioning and maintenance.
Consultation between all interested parties at an early stage of design cannot be over stressed to avoid expensive modifications to a completed
system.
The first stage of system design is to gather the
information needed on the project, normally
by consultation with the Regulatory Authority
and the user. This should cover legislative and
likely operational requirements and customer
preferences.

Emergency Lighting Initial Considerations
The Check List
l
The duration of the battery system is decided by:
l
Three hour duration is required in places of entertainment and for buildings where people may be sleeping.
l
Three hour duration is required if evacuation is not immediate, or early re-occupation is likely to occur.
l
One hour duration may be acceptable, in some premises, if evacuation is immediate and re-occupation is delayed until a full recharge of
the system has occurred. In practice it is normally preferable to choose a three hour system.
l
Escape routes should be established and potential hazards investigated.
l
Building plans need to be assembled showing the locations of fire alarm call points, the position of fire fighting equipment and fire and
safety signs.
l
Open areas (anti-panic) larger than 60m2 floor area should be identified.
l
High risk task areas should be identified and normal lighting levels established.
l
External illumination outside exit doors should be determined.
l
Other areas which need illumination although not part of the escape route, should be located, e.g. lifts, moving stairways and walkways,
plant rooms and toilet accommodation over 8m2 gross area.
l
All emergency luminaires should be wired from the unswitched side of each local lighting circuit.
l
Areas of low fire risk (if a central system is being used), and the locations of central battery units and cable runs should be established.
l
Standby lighting requirements should be established if activities need to continue during a failure of the normal lighting supply.
l
The customer’s preference and operating considerations should be ascertained.
Design of New Installations
When referring to the provision of emergency escape lighting, EN 50172: 2004 requires that
“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”

Design Guide
Design Stage 1
Locate luminaires at mandatory points of
emphasis
Decide upon the emergency escape routes
together with the points of exit and locate
luminaires at points of emphasis (these are
mandatory locations) along these routes.
Initial design is conducted by the siting of
luminaires to cover specific hazards and to
highlight safety equipment and signs.
This should be performed regardless of whether
the area is an emergency escape route or defined
as an open area. Only when this is accomplished
should the type of luminaire or its light output
be considered.
At each corridor intersection
Outside each final exit
At each exit door
At fire fighting equipment
On each staircase
At fire alarm call points
The points of emphasis where it is mandatory to
site escape lighting luminaires are as follows:
l
At each intersection of corridors.
l
At each exit door.
l
At each change of direction (other than on
a staircase).
l
On each staircase so that each flight of
stairs receives direct light.
l
At any other change of floor level.
l
Outside each final exit and close to it.
l
At each fire alarm call point.
l
At fire fighting equipment.
l
At each first aid post.
l
To illuminate exit and safety signs required
by the enforcing authority.
BS 5266: 1999 requires a minimum of 1.0 lux at
these points of emphasis except fire alarm call
points and fire fighting equipment where the
minimum required is 5.0 lux.

Design Stage 2
Consider other locations
Consider providing additional escape lighting at these locations:
l
l
Lift cars. Although only in very exceptional circumstances will they be part of the escape route,
they do present the problem that people may be trapped in them in the event of a supply
failure. Lift manufacturers are legally obliged to fit emergency lighting.
Toilets with facilities exceeding 8m2 floor area and all toilets for the disabled. Large tiled areas
such as changing rooms also fall under this category. This should be considered an open (antipanic) area.
l
Escalators, to enable users to get off them safely. This should be considered an open (anti-panic)
area.
l
Motor generator control or plant rooms require battery supplied emergency lighting to assist
any maintenance or operating personnel in the event of failure. It is also necessary to install selfcontained emergency lighting in areas adjacent to central battery systems in case of failure.
l
Covered car parks, the normal pedestrian routes should be provided with non-maintained
luminaires of at least one hour duration.
l
First aid rooms, the room together with the area immediately outside.
l
Lighting compartments, where provision has been made for a single luminaire to cater for a
room or corridor, this must be increased to a minimum of two, to prevent the area from being
plunged into darkness, if the luminaire fails.

Check minimum illuminance levels
When the points of emphasis have been covered, it is essential to provide any additional luminaires that might be necessary to ensure that
minimum illuminance levels are met.
BS 5266: Part 1: 1999 calls for a minimum of 0.2 lux at floor level on the centre line of permanently unobstructed escape routes. Points of
emphasis should be illuminated to a minimum of 1.0 lux.
There is no guarantee that obstructions will never occur, therefore it is advisable that 1.0 lux minimum is used throughout.
1
Decide upon the defined and open area (anti-panic) routes.
2
Check that the preferred luminaires can be used on defined escape
routes.
3
Place exit signs at each final exit.
4
Position luminaires outside each final exit and any others required to
aid dispersal. Note: These will probably be of the weatherproof variety.
5
Place extra directional exit signs where the final exit sign is obscured.
6
Illuminate all other ‘points of emphasis’ as defined in BS 5266: Part 7:
1999 These are:
l
Change of direction and level.
l
Fire fighting equipment.
l
Hazardous processes.
l
First-aid and plant rooms.
l
Tiled areas.
l
Escalators.
l
Signs.
7
Place luminaires along the defined escape route using the spacing
data. Note: Remember to add extra luminaires so that each lighting
compartment is covered by at least two luminaires.
8
Position luminaires into the open (anti-panic) areas using the current
standard 0.5 lux min. Note: EN 50172 / BS 5266-8 requires a
minimum of 2 luminaires in open areas.
It should be noted that transverse to transverse installation enhances the
performance of the luminaires.
Escape routes require minimum
levels of illuminance

Spacing Tables
BS 5266: Part 1: 1999 recommends using a larger number of low power luminaires rather than a few high power units, so that no part of
the escape route is lit by just one luminaire. Thus, if a luminaire fails, the route will not be plunged into darkness and the uniformity of light
distribution will be maintained.
Gent has calculated the maximum spacings for all Gent luminaires to ensure a given design illuminance for routes up to 2m wide.

Special considerations for escape routes and open (Anti-Panic) areas
Low Voltage Downlighters
Tungsten-Halogen downlighters are often used in ‘decorative’ and open (anti-panic) areas.
For either application ‘cone diagrams’ are used to calculate the spacing. A particular lamp is described by the ‘watts’ and an included beam angle.
Position the beams so that they just touch, this will maintain uniformity.
Note: The light levels achieved are far higher than those normally required.

High risk task area
BS 5266: Part 7: 1999 requires that higher levels of emergency lighting shall be provided in areas of particular risk, although no values are
defined.
The British standard states that the average horizontal illuminance on the reference plane shall be as high as the task demands in areas of high
risk. It shall not be less than 10% of the normal lighting level, or 15 lux, whichever is the greater. In practice this minimum is unlikely ever to be
a problem as it would only be valid if the risk area had a normal illumination level less than 150 lux.
High risk task area
High risk task area
Design Procedures
For a conversion unit, a direct ratio is obtained by using its ballast lumen factor (BLF). To achieve 10% of normal lighting use a minimum BLF of
0.1.
To provide 10% of normal lighting, it is advisable to use either high output single point units (Twinspots) or the conversion of the installed mains
luminaires to emergency operation.
Consideration can also be given to the use of a central battery system.

Locate exit signs and directions
BS 5266 states that:
“Signs are required at all exits, emergency exits and escape routes, such that the position of any exit or route to it is easily recognised and
followed in an emergency. Where direct sight of an exit or emergency exit is not possible and doubt may exist as to its position, a directional sign
(or series of signs) should be provided, placed such that a person moving towards it will be progressed towards an exit or emergency exit”.
The Format of Signs
Exits must be identified by the sign. Other information such as ‘Fire Exit for Emergency Use Only’ is now considered as a building management
sign that can be displayed if needed but is not part of the safety system.
Maximum Viewing Distance
Viewing distances are given in BS 5266: part 7: 1999 as 200 x H for a self illuminated sign, and 100 x H for externally illuminated signs where
H is the height of the pictogram.

Duration of emergency lighting system
BS 5266 Part 1: 1999 states:
“It is considered that a design period of operation of emergency lighting system of 1 hour should be the absolute minimum of even the smallest
premises considered in this code”.
For most applications a duration of between 1 hour and 3 hours should meet all normal requirements.
Type of System: Mode of Operation
The type and category of system used depends on the size and function of the premises. The system should provide for the safe movement of
people along the escape routes and through the exits.
The emergency lighting design should take account of individual lamp luminaire failure, mounting height, spacing, additional escape lighting
and emergency signs.
Self-contained luminaires contain their own battery charger, control gear and lamp, so that if the mains supply fails, the emergency lighting will
operate for the design duration. For central battery systems, the luminaire (known as a ‘slave’ luminaire) derives emergency lighting supply from
a central power source, which may be a standby generator or a central battery system.
Either type of luminaire can be ‘maintained’ or ‘non-maintained’. With maintained operation all emergency lighting lamps are in operation at all
times. For non-maintained emergency lighting, all the emergency lighting lamps are in operation only when the supply to the normal lighting
fails, the lamps are then illuminated from the battery and control gear. When the mains is restored the lamps are switched off and the battery
is recharged ready for the next failure.
10
BS 5266 recommends a maintained mode of operation for premises where the normal lighting can be dimmed or reduced below the levels
required for the identification and illuminance of escape routes while the premises are occupied e.g. theatres and cinemas. EN 50172:2004 also
recommends maintained exit signs where the occupants may be unfamiliar with the building.
A non-maintained mode of operation may be suitable for all other premises.

Design Stage 7
Commissioning, testing and maintenance
Control
Once the design has been completed it becomes apparent that the performance of the luminaire depends as much on the light distribution as it
does the light output available. Consequently it becomes essential that luminaire types specified for a particular design are not changed without
a reappraisal of the photometric design.
Testing and Log Book
The system should include adequate facilities for testing and recording the system condition. These need to be appropriate for the specific site.
It may well be desirable to test the installation in an office block by isolating the total supply, but this would be inappropriate in a hotel which is
occupied 24 hours a day, seven days a week. For a hotel, a test system able to be tested by zone would be more suitable as the risks of having
all the luminaires discharged while the building is occupied can be eliminated. To meet the requirements of EN 50172 a full duration test should
be undertaken annually, with short duration tests monthly.
Commissioning Certificate
BS 5266 Part 1: 1999 requires written declaration of compliance to be available on site for inspection. These consist of:
1 Installation quality
This means IEE regulations, HD384-5, must have been conformed to with suitable cable, adequate support and protection having been used.
The requirement in BS 5266, that non-maintained fittings are fed from the final circuit from the normal lighting in the area, must have been
complied with.
2 Photometric performance
Evidence of compliance with design criteria must be obtained. Gent registered fittings are independently photometrically tested and their spacing
data registered by the ICEL scheme. Copies of this data present the verification required provided that the spacings are not exceeded.
3 Declaration of a satisfactory test of operation
A declaration of satisfaction test of operation is also needed.
4 Log book
A log book should be kept and be readily available for inspection.
It should record the date and brief details of completion, any alterations, periodic inspections and test certificates, each service, inspection or
test carried out, defect and remedial action.
Maintenance
Finally to ensure that the system remains at full operational status, essential servicing should be defined. This normally would be performed
as part of the testing routine, but in the case of consumable
items, such as replacement lamps, spares should be provided for
L
immediate use.

Design Guide – Glossary
by Honeywell
Ballast - controls the operation of a fluorescent lamp from a specified low or high voltage AC or DC source (typically between 12 and 240 volts). It can also include an element for starting the
lamp and sometimes for power factor correction or radio interference suppression.
Ballast Lumen Factor (BLF) - is the ratio of the light output of the lamp when the ballast under test is operated at its design voltage compared with the light output of the same lamp operated
with the appropriate reference ballast supplied at its rated voltage and frequency.
Battery - secondary cells providing the source of power during mains failure.
Battery Sealed (recombination) - a battery that is totally sealed, or constructed so that no provision is made for replacement of electrolyte.
Battery Unsealed (vented) - a battery that requires replacement of electrolyte at regular periods.
Battery Capacity - is the discharge capability of a battery being a product of average current and time expressed as Ampere hours over a stated duration. Note: A shorter total discharge period
gives rise to a smaller available capacity.
Central Battery System - is a system in which the batteries for a number of luminaires are housed in one location, usually for all emergency luminaires in one lighting sub-circuit sometimes
for all emergency luminaires in a complete building.
Combined Emergency Luminaire (sustained) - contains two or more lamps at least one of which is energised from the emergency supply and the remainder from the normal supply.
Design Voltage - is the voltage declared by the manufacturer to which all the ballast characteristics are related.
Emergency Lamp Design Lumen (ELDL) - is the claimed output of the lamp measured at the end of the declared lamp life, multiplied by the Ballast Lumen Factor (BLF) of the specific
emergency lighting circuit.
Emergency Lighting - is the lighting provided for use when the supply to normal lighting fails.
Escape Route Lighting - is provided to ensure that the means of escape can be effectively identified and safely used when a location is occupied.
Emergency Exit - a way out that is used during an emergency.
“F” Mark - shows the luminaire can be mounted on combustible surfaces.
Final Exit - is the terminal point of an escape route, beyond which point persons are no longer in danger from fire or any other hazard requiring evacuation of the building.
High Risk Task Area Lighting - is that part of emergency lighting provided to ensure the safety of people involved in a potentially dangerous process or situation and to enable proper shutdown
procedures for the safety of the operator and other occupants of the premises.
Glow Wire - 850ºC Test - all emergency luminaires on escape routes must pass this test. Self-extinguishing grades of polycarbonate, PVC or glass and steel are needed.
Illuminance - is the luminous flux density at a surface i.e. the luminous flux incident per unit area. The unit of illuminance is lux, that is, lumens per square metre.
K Factor - is the amount that the lamp output will reduce because of the effect of battery discharge. This factor will vary dependent on the control gear characteristics. The final applied minimum
voltage and type of lamp. Values can vary from 0.55 for tungsten lamp to a factor of about 0.75 to 0.85 for a fluorescent circuit.
Lighting Design Lumens (LDL) - is the claimed lamp light output measured on a standard reference circuit at the end of the declared lamp life.
Luminaires - are apparatus which distribute, filter and transform the lighting given by a lamp or lamps and which include all the items necessary for fixing and protecting these lamps and for
connecting them to the supply circuit. Note: Internally illuminated signs are a special type of luminaire.
Maintained Emergency Luminaire - is a luminaire in which the emergency lighting lamps are energized at all times when normal or emergency lighting is required.
Mounting Height - is the vertical distance between the luminaire and the floor.
Non-Maintained Emergency Luminaire - is a luminaire containing one or more lamps which operate from the emergency supply only upon failure of the normal mains supply.
Normal Lighting - is all permanently installed artificial lighting operating from the supply in normal use, which in the absence of adequate daylight is intended for use during the whole time
that the premises are occupied.
Open Area (Anti-panic) Lighting - is that part of emergency escape lighting provided to avoid panic and provide illumination allowing people to reach a place where an escape route can
be identified.
Rated Duration - is the manufacturer’s declared duration for a battery operated emergency lighting unit, specifying the time for which it will operate after mains failure. This may be for any
reasonable period, but is normally one or three hours (when fully charged).
Rated Load - is the maximum load which may be connected to the system which will be supplied for the rated duration.
Re-Charge Period - is the time necessary for the batteries to regain sufficient capacity to achieve their rated duration.
Room Index - defines the relationship between the height, length and width of a room used for illuminance calculations.
Self-Contained Emergency Luminaire - is a luminaire or sign providing maintained or non-maintained emergency lighting in which all the elements such as battery, the lamp and the control
unit are contained within the housing or within one metre of the housing.
Service Factor (SF) - is the ratio of the illuminance provided by an aged system with dirty luminaires to the illuminance of the same system when new.
Single Point Luminaire - (see self-contained emergency luminaire).
Slave or Centrally Supplied Luminaire - is an emergency luminaire without its own batteries that is designed to work in conjunction with a central battery system.
Standby Lighting - is the part of emergency lighting which may be provided to enable normal activities to continue in the event of a mains supply failure.
Uniformity - is the ratio of average illuminance to the minimum illuminance measured at the working plane.
Utilisation Factor (UF) - is the proportion of light emitted by the lamp in the emergency lighting luminaire that reaches the working plane.

Central Battery Systems
Central battery systems provide
a solution to power and test an
array of emergency luminaires
all from one central point. The
luminaires are all wired back
to a main cabinet housing
the
batteries
and
charger.
This cabinet can be housed
in a secure location that only
authorised personnel can access.
Due to the life safety importance
of emergency lighting, central
battery systems should always
be wired in fire protected cables.
This reassures the end-user that
in a fire situation the power
to the luminaires would not be
lost.
Testing and maintenance
Either AC or DC systems can be provided with a comprehensive range of slave luminaires to suit.
AC CENTRAL BATTERY SYSTEMS
AC features:
l
High efficiency and reliability
l
Low operating cost
l
Wide range of standard ratings available, with batteries to suit all applications
l
For use with a wide range of normal mains voltage fittings, including fluorescent and HID
l
High light levels achievable
The principal advantages of the AC systems is that the wide range of light fittings available for use
with normal mains can be used with the inverter. This results in higher light levels being achieved when
using AC systems than achieved using the traditional low voltage emergency luminaires.
An end user should always
ensure that regular testing and
maintenance is carried out for
all emergency lighting products
in accordance with BS5266. This
is much easier with a central
battery system because testing
can be controlled at one central
point. A competent engineer
should always be used to carry
out maintenance.
DC CENTRAL BATTERY SYSTEMS
Cost of ownership
DC features:
On-going costs are also reduced
l
Wide range of standard ratings
l
Extensive choice of battery types
l
Comprehensive instrumentation and monitoring
l
Gent DC central emergency power systems automatically provide an alternative lighting supply
in the event of AC supply failure
l
Long battery design life of between 5 and 25 years depending upon the type chosen
l
Comprehensive ranges of options are available to customise equipment to each individual
application
because with a central battery
system the batteries can have
a design life of up to 25 years
where
self-contained fittings
need changing every 4 years.
