Linsheng is a Emergency Light Manufacturers for quality production of emergency lighting. Emergency lighting is one of the frequently asked topics. In order to give you a more comprehensive understanding of emergency lighting, Linsheng Emergency Light combines with many years of experience in production testing to provide an emergency lighting guide for you to think about some issues:
1. What is emergency lighting?
Emergency lighting is lighting that illuminates in the event of a main power failure. The emergency lights are powered by a rechargeable backup battery, which is located in the emergency light or in the central battery position, and each emergency light is connected. Emergency lighting is a general term that is divided into emergency escape lighting and alternate lighting. Standby lighting is used to continue normal operation during a power outage, and since this is not a legal requirement, this guide does not cover it.
2. What is emergency ESCAPE lighting?
When the main power supply fails, the emergency escape lighting automatically starts and emits enough illumination to allow passengers and visitors to safely evacuate the home.
3. Emergency escape lighting itself is subdivided into
Open area lighting (bulkhead and other emergency lights)
Escape route lighting (usually illuminated fire exit sign with whites running on a green background)
High-risk mission area lighting (allowing to close dangerous processes)
The law requires public access to buildings and most businesses to provide emergency escape lighting.
4. What are the key types of emergency lights?
There are two main types of emergency lighting: maintenance and non-maintenance.
The maintained emergency light is always on and remains lit for the shortest emergency duration (usually 3 hours) after a power failure. Maintenance emergency escape lights are used in theaters, cinemas, entertainment halls and other gathering places, as well as shopping centers and similar places. They allow the public to become familiar with emergency routes and have the advantage of being able to immediately detect any malfunction of the emergency lighting bulb.
Unmaintained emergency lights will only illuminate in the event of a main power failure and will remain lit for the shortest emergency duration required. Unmaintained emergency lights may be found in offices, shops and factories.
5. Do you have to illuminate all escape route lighting?
If there is sufficient open area emergency lighting near the fire exit, a non-illuminated fire exit sign can be used in less important locations. In this case, a photoluminescent fire exit sign is preferred, although sufficient light must be ensured to reach the photoluminescent sign to ensure that it is always "charged".
National standards provide clear guidance on the design and installation of emergency lighting. It should be borne in mind that British standards set out best practices for standard situations, but specific installations may require higher standards.
The actual illumination should be closely related to the nature of the house and its occupants.
Special consideration should be given to crowded places such as nursing homes, hospitals, bars, discos and supermarkets, and whether the premises are residential.
The borrowed lighting can be applied to small houses (such as small shops) where light enters the building from a reliable external source, for example, a street light that will fully illuminate the escape route. Alternatively, a single "independent" escape lighting unit may be sufficient in a small house that can sometimes be combined with an exit or direction sign.
The emergency lighting system should be installed by an electrician specializing in emergency lighting.
They need to be familiar with BS 5266-1-2011 emergency lighting - Part 1: Code of practice for emergency lighting.
The school’s request for emergency lights is a bit like anomalies.
Since the school only works during the day, no emergency lighting is required. However, if the school is used during non-working hours, such as in the lobby, emergency lighting should be installed on the lobby and exit routes. The “responsible person” should have the final decision on this and may want to consult a local fire officer.
Toilet facilities used by disabled persons and/or any multiple closet facilities without borrowed lights should have emergency escape lighting from at least one luminaire. If there are no borrowed lights, the organization may have to provide emergency escape lighting in each compartment.
7. What are the rules for renting a property?
For residential properties, the landlord is considered the “responsible person” for all fire safety and emergency lighting.
Single-family homes and multi-storey homes with up to two storeys require only traditional lighting, and if the escape route is complex and there is no effective borrowing, the third and fourth floors may require emergency escape lighting.
Multi-storey mattresses occupying one to four floors (with separate cooking facilities on the bed) require traditional lighting and emergency escape lighting, if the risk requires or there is no effective borrowed light. Multi-storey five- or six-story bed home with separate cooking facilities that require traditional lighting and emergency escape lighting
If a fire risk assessment requires it, the conversion of a two-, three- or four-story house into a detached apartment requires traditional lighting and emergency escape lighting.
The five or six-storey houses were converted into separate apartments that required traditional lighting and emergency escape lighting. It is important that the common escape route should be well lit.
There are guidelines to help understand the required regulations, and landlords need to understand their responsibility for conducting fire risk assessments and ensure that their property has appropriate and appropriate fire safety measures.
8. How do you maintain emergency lighting?
Emergency lights must be tested periodically unless they are self-test emergency lights.
An emergency light with a built-in backup battery shows a small green LED indicating that the internal battery is charging. Older models may have red lights. However, you still need to check the function of the emergency light regularly, as the LED only confirms that the device is charging, not the entire time period required for the battery to continue or the lamp is in normal working condition.
All emergency lighting systems must be tested once a month. This test is based on the short-term functional test of BS EN 50172:2004 / BS 5266-8:2004.
The time to simulate the fault should be sufficient for the test while minimizing damage to system components, such as lights. During this time, all fixtures and signs should be inspected to ensure they are present, clean and functioning properly. An emergency lighting key switch can be used to interrupt the power to the emergency light without affecting the power supply to the normal lighting circuit.
The entire duration of the emergency light (usually 3 hours) must be tested annually. At the end of this test, the emergency light must still work. The results must be recorded and these results must be corrected as soon as possible if a failure is detected.
Any battery that cannot last for three hours should be replaced immediately.
Life expectancy will vary depending on battery usage - some people expect a life expectancy of 4 years, which is about 5 years. When the life expectancy expires, the battery should be replaced. It is best to write the date of installation on the battery when replacing the battery for future reference.
If the accessory has a fluorescent tube, the life depends on whether the device is maintained or not.
The emergency light manufacturer recommends that the lights in the maintenance bulkhead be replaced every six months. If the end of the fluorescent lamp turns black / begins to darken, the lamp needs to be replaced.
The occupier/owner of the premises shall appoint a competent person to supervise the testing of the system. This person should have sufficient authority to ensure that any work required to maintain the proper functioning of the system is performed. Competence can be defined as someone with sufficient training and experience or knowledge and other qualities that allow them to properly maintain the system. The level of competence required will depend on the complexity of the situation and the special assistance required.
From a practical point of view, the average caregiver can use the test key to remove the power from the emergency light and ensure that the emergency light remains within the required time period. When repairing a failed emergency light, an electrician is likely to be required unless the caregiver is sufficiently qualified to replace the battery and luminaire.
But it is important that all tests are recorded in the fire safety log.
If the lamp is replaced before it completely fails, the life of the emergency lamp will be longer. However, this recommendation may only apply if the organization has a contractor to maintain emergency lighting and the cost of the call is high. In this case, preemptive maintenance (replacement while the lights are still working) makes sense.
In the long run, LED lamps are more economical than fluorescent tubes because they not only save power when the lamp is turned on, but also save power even during trickle charging of the battery. However, the real savings in LED emergency lights come from the fact that it is not necessary to replace the tubes annually or annually. LEDs will last longer, saving the cost of maintenance calls and tube replacement.
Many systems install a fishtail key switch in the power supply to form a suitable emergency light set so you don't have to turn off the fuse level power supply during inspection. If your system can only be tested by turning off the lighting completely, you can only test when the building is empty and have the appropriate portable light or appropriate daylight in all the locations you are checking. If your company has a dangerous process, lighting may have to be turned on all the time, so central shutdown is not appropriate.
