In the event of a power outage at work or in a residential complex, battery powered lights may switch on to allow the safe evacuation of the people within.
The early backup systems were often bigger than the lights themselves due to the inefficient way power would be stored.
In modern times, floodlights and halogen lamps are the most commonly used bulbs in these systems.
Commonly, emergency lighting batteries are made of lead calcium and can last for 10 years or more on continuous charge. Emergency lighting is lighting for an emergency situation when the main power supply is cut and any normal illumination fails.  The loss of mains electricity could be the result of a fire or a power cut and the normal lighting supplies fail. Emergency lighting is normally required to operate fully automatically and give illumination of a sufficiently high level to enable all occupants to evacuate the premises safely. The British Standard provides the emergency lighting designer with clear guidelines to work to. Lighting that automatically comes on when the power supply to the normal lighting provision fails.
Emergency lighting is a general term and is sub-divided into emergency escape lighting and standby lighting. Emergency escape lighting – that part of an emergency lighting system that provides illumination for the safety of people leaving a location or attempting to terminate a potentially dangerous process beforehand. Standby lighting– that part of an emergency lighting system provided to enable normal activities to continue substantially unchanged. Emergency escape lighting is itself sub-divided into escape route lighting, open area lighting and high risk task area lighting. Escape route lighting – that part of an emergency escape lighting system provided to ensure that the means of escape can be effectively identified and safely used by occupants of the building. Open area lighting (in some countries known as anti-panic lighting) – that part of an emergency escape lighting system provided to minimise panic and ensure there is sufficient illumination to allow the occupants of a building to reach a place where an escape route can be identified. High risk task area lighting – that part of an emergency escape lighting system that provides illumination for 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 and other occupants of the premises.
Low hardware equipment costs – no requirement for extended wiring, special ventilation etc. In general, the decision to use either a central battery or a self-contained system is likely to be cost determined. Maintained or non-maintained is the principal consideration, which is decided by the use of the premises.
Maintained emergency luminaire: a luminaire in which the emergency lighting lamps are on at all times. Maintained mode is generally used in places of assembly such as theatres, cinemas, clubs and halls; the full list is contained in BS 5266. Non-maintained emergency luminaire: a luminaire whose emergency lamps only come on when the power supply to the normal lighting fails. Combined emergency luminaire: a luminaire containing two or more lamps, at least one of which is energized from the emergency lighting supply and the other(s) from the normal lighting supply.
Compound self-contained emergency luminaire: a luminaire providing maintained or non-maintained emergency lighting and also the emergency power supply to a satellite luminaire. Satellite emergency luminaire: a luminaire for maintained or non-maintained operation and which derives its emergency operation supply from an associated compound self-contained emergency luminaire. A) Luminaire including test device: the luminaire contains a self-test module for testing purposes. B) Luminaire including remote test device: the system is tested remotely by a centralised panel. C) Luminaire with inhibiting mode: a control mode used to inhibit the emergency lighting luminaire from operating, thus preventing the discharge of the emergency lighting batteries at times when the building is unoccupied. D) High risk task luminaire: for risk task area lighting in areas of high risk, the maintained luminance shall not be less than 10% of the required maintained luminance for the task under normal lighting conditions. A minimum duration of 3 hours should be used for emergency escape lighting if the premises are not evacuated immediately, as in the case of sleeping accommodation, for example, or if the premises will be reoccupied immediately the supply is restored without waiting for the batteries to be recharged. One hour’s duration should only be used if the premises are evacuated immediately on supply failure and not reoccupied until full capacity has been restored to the batteries.
BS 5266 contains detailed information on the recommended duration of systems in various premises.
Having decided on your basic system, consideration should now be given to the siting of the lighting units and signs within the particular premises involved. Lighting units and signs should be sited so as to clearly show the exit routes leading to the final exits from the premises. In general, if careful consideration is given to siting the luminaires and signs to cover these areas, the completed scheme will meet most requirements.
It is not necessary to provide individual lights (luminaires) for each item above, but there should be a sufficient overall level of light to allow them to be visible and usable.
BS 5266 and the European Standard both require written declarations of compliance to be available on site for inspection.  These should detail the quality of the installation and its conformance to IEE regulations, including the main circuit of the normal lighting system feeding non-maintained fittings. Photometric performance is required and evidence of compliance with light levels has to be supplied by the system designer. A declaration of satisfactory test of operation is necessary and a log of all system tests and results must be maintained. Finally, to ensure that the system remains at full operational status, essential servicing should be specified. In a system with a single switch for the whole building or a large circuit, after simulating the mains failure it is necessary for the tester to walk the whole building or circuit, to check all emergency luminaire are operating correctly. If the emergency luminaires are individually switched, only a single walk around the building will be needed. If the costs of an engineer’s time and the disruption caused by manual testing are excessive, self-testing emergency lighting should be considered. Because of the possibility of a failure of the normal lighting supply occurring shortly after a period of testing of the emergency lighting system or during the subsequent recharge period, all full duration tests shall, wherever possible, be undertaken just before a time of low risk to allow for battery recharge.
The following minimum inspections and tests shall be carried out at the intervals recommended below. This check only applies to emergency lighting systems with a central back-up battery system. The period of simulated failure should be sufficient for the purpose of this test while minimising damage to the system components, e.g. The result must be recorded and, if failures are detected, these must be remedied as soon as possible.

Emergency lighting is now covered by a series of interdependent standards that can be seen as forming a hierarchy as shown below. Visit your local reference library or purchase copies of the requisite standards from BSI online; insert the BS number to see which titles are current. The HM Government entry level guides to the RRFSO for different types of non-domestic premises and the communal areas in HMOs each have a section entitled “Further guidance on emergency escape lighting”, which provide additional relevant information. Through National emergencies like Hurricane Katrina and the Japanese Tsunami, we have discovered a great need for reliable, efficient emergency lighting. Most emergency lighting uses traditional incandescent lamps that are powered by a generator. Glow in the dark paints and dyes are now being commissioned for use in emergency lighting for stairwells, corridors and exit ramps in addition to exit signs. Contact you local power supplier, as many are now offering to subsidise the cost of installing more power efficient and safe emergency lighting. Floods, fires and hurricanes can be overwhelming and life-threatening, but many of the casualties associated with these devastating events can be prevented with the proper knowledge.
All battery powered exit and emergency lights must be maintained at least annually per code requirements plus the manufacturer’s directions, and includes a full function test on every battery powered exit and emergency lighting system.
Local, State and National Codes, along with insurance company requirements, dictate that all commercial, industrial, institutional and certain multifamily residential facilities have appropriate means of egress marked with readily visible signs installed and properly maintained. A facility owner is required to insure an inspection is conducted at least monthly of all exit and emergency lights and a 30-second functional test be conducted on all battery powered fixtures. Benville & Marsh have been designing, installing and servicing fire alarm and emergency lighting systems in all types of buildings for many years. As we are totally independent and not tied to any manufacturer, we can design and install the most suitable system for your particular requirements. This can be anything from a simple domestic system right through to the very latest analogue addressable systems installed in the most complex industrial or commercial environments.
Our fire alarm and emergency lighting systems comply with the latest British Standards and codes of practise. Benville & Marsh Ltd have been designing, installing and servicing fire alarm and emergency lighting systems in all types of buildings for many years.
Benville & MarshWe are one of the leading electricians and electrical contractors in the Thames Valley. Ascot, Basingstoke, Bracknell, Crowthorne, Earley, Eton, Fleet, Hungerford, Lambourn, Maidenhead, Marlow, Newbury, Reading, Sandhurst, Slough, Thatcham, Virginia Water, Windsor, Wokingham, Woodley and Yateley. They must be built in as the property is constructed, however the wiring system cannot be linked to any other electrical services supplied. The battery is the most important part as it supplies the power to this essential safety feature.
They were mainly supplied with lead-acid batteries with high voltage and this was not cost effective. Advances in technology have meant that the voltage requirements have been drastically reduced to 6-12 volts and the batteries have decreased in size accordingly. This may lead to sudden darkness and a possible danger to the occupants, either through physical danger or panic.
Most new buildings now have emergency lighting installed during construction; the design and type of equipment being specified by the architect in accordance with current Building Regulations and any local authority requirements.
BS 5266-1: 2011 embraces residential hotels, clubs, hospitals, nursing homes, schools and colleges, licensed premises, offices, museums, shops, multi-storey dwellings, etc. It is part of the fire safety provision of a building and a requirement of The Regulatory Reform (Fire Safety) Order 2005. This guide does not include standby lighting as it is not a legal requirement and is a facility that may or may not be needed, depending on the use and occupancy of the premises, etc. The designer, responsible person and fire risk assessor should meet and decide where the escape lighting is required and mark up a plan showing the areas to be covered, the type (power supply), mode of operation, facilities and duration.
If an installation has longevity and low maintenance as priorities, then the higher cost of a central battery may be acceptable on a very large project.
The lights are typically dimmed when these premises are occupied and the emergency escape lighting prevents total darkness. Non-maintained is the typical mode in a workplace or similar environment in which artificial lighting is normally deployed while the premises are occupied. If a mains failure occurs at such a time, the batteries will remain fully charged so that the building can be occupied when required. Where the exit route or final exit is not readily identifiable, a sign should be utilised rather than a lighting unit.
The above is a brief summary and we recommend that the appropriate standard is studied to gain a full understanding of what is involved. In addition, for escape routes of up to 2m wide, 50% of the route width should be lit to a minimum of 1 lux.
System logbooks, with commissioning forms, testing forms and instructions, should be provided by the installer. This would usually be performed as part of the testing routine, but in the case of consumable items such as replacement lamps, spares should be provided for immediate use.
After restoring the mains supply, the whole building or circuit must be walked again, to check that the emergency lights are recharging.
However, the test switches could spoil the decor of the building and they must be of a type that is tamper proof. Additional information on servicing can be found in BS 5266-1: 2011 (Code of practice for the emergency lighting of premises).
In buildings that are permanently occupied, the test should be phased so only alternate luminaires are tested. Alternatively, suitable temporary arrangements shall be made until the batteries have been recharged. In this case, there is a daily visual inspection of indicators on the central power supply to identify that the system is operational. Gives general rules and guidance on the provision and operation of emergency lighting in most premises other than dwelling houses.
Specifies the illumination to be provided by emergency lighting (including luminance, duration and colour). Buildings without emergency lighting will remain dark in the event of a power outage, making the evacuation slower for all concerned. The capability to illuminate darkened areas during a disaster, decreases the liability of building owners and helps ensure people will be able to exit in a more orderly fashion.

Fire escapes, fire extinguishers and the signs themselves comprise the three absolutes of building safety, and skimping on any of the three can have disastrous consequences. You can get battery backup, self-luminous signs with contained chemical lighting elements, and countless options for cool-burning LEDs.
Lighting the way to freedom is one of the surest ways to keep your employees and co-residents out of harm's way, which is why more experts advise sticking with exit signs that are flame tested and sturdily constructed. Personnel making inspections must keep records of all units inspected, including those found to require corrective action. Ltd does not currently advertise comprehensive company & product information with Global Sources. Initially, normal light bulbs were used to much criticism due to the amount of light they could give off. Although this standard recommends the types and durations of emergency lighting systems relating to each category of premises, it should be remembered that the standards are the minimum safe standards for these types of building and that a higher standard may be required for a particular installation. Typically, luminaire and installation costs are a major consideration, particularly on smaller jobs, and it is this criterion which makes the self-contained luminaire the most popular choice. It is performed by an inhibitor switch that must be interfaced with other building services so that the premises cannot be inadvertently occupied without the emergency lighting being recommissioned. A free fire safety logbook with sections for emergency lighting tests can be downloaded free from Safelincs. After the tests, it is recommended that the performance of the system is logged in the fire safety logbook.
This person shall be given sufficient authority to ensure the carrying out of any work necessary to maintain the system in correct operational mode.
During this period, all luminaires and signs shall be checked to ensure that they are present, clean and functioning correctly.
Research has shown that individuals remain calmer when they are able to identify a clear escape route in an emergency.
Having sufficient space for backup generators makes them less desirable for widespread use and inaccessible to many family homes. These materials ensure safe, effective low voltage as means of providing emergency lighting. They are basically glowing signs that display the word EXIT in either red on a white background or green on a white background. The life of an incandescent bulb is short, meaning a replacement will be needed every 3-5 months. That's why at FlameGuard Fire Equipment, Inc, we take care to ensure every one of our products exceeds state and federal regulations throughout the country. Many of our models draw a tenth of the power those older versions swallow, yet last longer and look better throughout your public spaces. Access to fire alarm call points and fire fighting equipment should be clearly illuminated. The actual degree of illumination should be closely related to the nature of both the premises and its occupants, with special consideration being given to care homes for the elderly, hospitals, crowded venues such as pubs, nightclubs and supermarkets, and to whether or not the premises have overnight accommodation, e.g. This test does not apply to emergency lighting with self-contained back-up batteries in each unit (standard emergency lighting).
Manufactures like Utilitech are looking to improve their emergency lighting products all the time, in addition to making them safer, they are working on lowering their power consumption and improving efficiency. Generators need a lot of space and a fuel (normally diesel) to operate, if they are not well maintained, they could fail to work in an emergency, leaving those involved with not light at all. Emergency exit signage has to be fitted in all public places and places of work by order of federal, state, and local laws.
