In 2024, The Chinese New Year will begin on February 10th and will be the year of the Dragon. This sixteen day long traditional Chinese holiday is recognised worldwide by many people across Asia, and increasingly in the Western world, along with festivals and celebrations to mark the Lunar New Year.

Following our top tips for celebrating will ensure that everyone can enjoy this tradition safely.

Fire Safety Top Tips for Chinese New Year

Whether organising a large event with fireworks and flames, or a small home gathering with sparklers and candles, Chinese New Year celebrations come with a fire risk. We have put together top tips for fire safety to help you make your event a safe and happy occasion.

1. Before your event you will need to carry out a fire risk assessment. This free assessment form will help you identify your fire risks and document your actions to reduce these risks. As the organiser of a public event, you have a legal duty to complete a fire risk assessment.

2. Consider how you will raise the alarm in the event of a fire. If you celebrate at home, do you have heat and smoke alarms fitted? When planning a public event, consider using site alarms or a rotary bell and having site stands with all your fire safety and first aid equipment at strategic places.

3. Prepare for any activities involving flames with adequate supplies of fire safety equipment. We recommend having fire blankets, water mist fire extinguishers, and a burns kit on hand for any eventuality. Our water mist fire extinguishers are non-toxic. This makes them particularly suitable for events with large numbers of spectators, or where children and animals may be present. Water mist extinguishers are environmentally friendly and leave no residue when discharged.

4. Even for an outdoor event like Chinese New Year, pathways should be kept clear of debris to ensure that people can move to a place of safety in a fire. Where crowds are expected, fire assembly points and exit routes should be clearly signposted.

Happy Chinese New Year!

Safelincs would like to take this opportunity to wish everyone celebrating the Chinese New Year good health and happiness.

Fire safety tips for student accommodation

Off to university and renting student halls or a shared home? Did you know that someone living in rented or shared accommodation is 7 times more likely to have a fire? If this is your first time living in rented accommodation, read our top 5 fire safety tips for students to keep yourself and your housemates safe.

Our Top 5 Fire Safety Tips for Students

  1. Read our guide on what to look out for when renting a home so you can be sure that your landlord or housing provider is doing their bit to protect you in the event of a fire.
  2. Test your smoke alarms regularly and replace the batteries straight away if there is a low battery warning. If your smoke alarm is beeping and you can’t solve the problem, notify your landlord.
  3. Take care when cooking! Over half of all accidental fires at home happen in the kitchen. Keep loose clothing, tea towels and cloths away from the cooker and hob. Make sure your oven and hob are cleaned regularly to avoid grease and oil building up and always check you have turned off appliances after using them. If you are frying food, take care not to let oil get too hot – if the oil starts to smoke, turn the heat down as it could burst into flames. Always keep an eye on your cooking – don’t be distracted by devices or by others. Set a timer so that you don’t forget to check the food regularly. It’s best to avoid cooking if you have been drinking alcohol as it is more likely that you will have an accident.
  4. Avoid burning candles or incense inside the house as they are at risk of starting a fire if knocked over or could set fire to a curtain or other fabric nearby. To make your new room cosy use battery operated candles and reed defuses as a safer alternative. Smoking inside the house could also start a fire accidentally.
  5. Electrical devices, cables and plug sockets can cause a fire! If your charging cable is cracked, severely twisted or has exposed wires, don’t use it, it could cause a fire. Buy a replacement from a well-known manufacturer. Don’t charge your phone or laptop on your bed or any other surface that could catch fire, instead opt for a work surface or table. Turn off electrical chargers, devices or appliances before bed or when leaving the house. Mobile phones that are charged on beds and under pillows get easily overheated and can start a fire.

    Did you know, sockets and plug boards have a limit on how many items can be plugged into them? Plugging too many plugs into a socket or extension cable could overload it and cause a fire. You can use this socket calculator to check whether your extension leads and adaptors are overloaded.

If you are worried about fire safety in your home, why not take our online home fire safety check? Answer questions about your student accommodation and you’ll be provided with advice about the best way to prevent a fire.

10 Things You Should Know About Fire Doors

Your Fire Door Questions Answered

Most of us will come into contact with fire doors in our daily life, either at home, at work or in public buildings. But how much do you know about fire doors and their role in saving lives? We’ve compiled a list of key fire door questions based on what customers ask our experts in our fire safety forum.

Fire doors stop fire and smoke from spreading to other parts of the building

1. Why are fire doors so important?

Fire doors are important because they keep fire or smoke in the room or ‘compartment’ in which it started. They stop it from spreading to other areas of the building. Fire doors are an integral part of any building’s passive fire protection system.

2. What do fire doors do?

Fire doors save lives and prevent further damage to the building and its contents:

  • They contain the fire in the room in which it started
  • Fire doors keep escape routes, such as corridors, clear from fire, giving occupants of the building longer to escape and better access for the fire service
  • They protect the remainder of the building, its contents and other buildings nearby from further damage.

3. How do fire doors work?

Fire doors prevent the spread of fire for a specified time. They are constructed from materials that will withstand fire for either 30 minutes or 60 minutes, depending on the fire door rating. Fire doors are fitted with intumescent strips in a groove on every edge of the door or fire door frame. When a fire breaks out, the heat causes the intumescent strips to expand to fill the gap between the fire door and the frame. This seals the room and stops the spread of fire for a given time. A fire door will only work if it is closed when the fire breaks out, so you should always ensure that your fire door is fitted with an automatic door closer and a sign that identifies the door as a fire door.

Key facts about fire doors

4. How are fire doors made?

Fire doors are usually thicker than a standard door and most have a solid core of variable material. The construction of fire doors varies depending on the manufacture. But, the critical part is that it is tested and certified to withstand fire for at least 30 minutes. Manufacturers must have the design of their fire doors and frames tested together as a set at an approved fire door testing centre. Then they must be considered for certification. When certification is approved, every fire door set constructed to the same design specifications by that manufacturer will be fixed with a label. The label identifies the manufacturer, date of manufacture and fire rating. This label can usually be found on the top edge of the door.

5. How long do fire doors last?

Fire doors and their frames are usually tested to hold back fire for 30 minutes (FD30) or 60 minutes (FD60). Their ability to withstand fire is dependent on them being properly installed with the correct seals and fire rated hardware including fire door closers. The condition of a fire door, especially one that’s in regular use could deteriorate over time. Check your fire doors regularly and ensure any fire door maintenance is attended to promptly. Fire door inspections can help to identify non-compliant fire doors. Fire doors can have a rating greater than 60 minutes but these are not required in most situations.

6. Are fire doors a legal requirement?

Fire doors are a legal requirement in all non-domestic properties, such as businesses, commercial premises, and public buildings. They are also required in residential flats and houses of multiple occupancy. As set out by the Regulatory Reform (Fire Safety) Order 2005, building operators in England and Wales should appoint a ‘Responsible Person’ to manage their fire safety precautions. Their legal responsibilities include a duty to reduce the risk of fire spreading within the premises. Fire doors play an important part in reducing this risk in many buildings. These types of buildings should have a fire risk assessment carried out. Fire risk assessments are an in-depth review of the premises. They will highlight any fire risks with recommendations to reduce or eliminate these risks, including where fire doors should be used and what rating they should be.

7. Do I need fire doors in my house or flat?

Fire rated doors can be a great way to add extra protection against fire in your home. But are they a legal requirement?

Houses and bungalows: In many homes in the UK fire doors are not a legal requirement, however there are some exceptions. Building regulations details where fire doors should be used:

  • Any new build or home renovation that has three or more floors must have fire doors fitted to every habitable room that leads from a stairwell. This applies to loft conversions where an extra floor has been added to a two-storey home.
  • Any door leading from your home into an integral garage must be a fire door. In most domestic situations, FD30 (fire doors with a 30 minute fire rating) are sufficient.

Flats and HMOs: Your block of flats should have had a fire risk assessment carried out. This will detail which doors are required to be fire doors. Building regulations Approved Document B2 sets out the following standards:

  • Every flat within a block of flats or HMO should have a fire door fitted at the entrance onto the communal area.
  • Flats located on floors 4.5m above ground level must have a fire rated door fitted between all habitable rooms as well as the front door.
  • Ground floor flats do not usually need internal fire doors as long as each room has an accessible way to escape. They do still need a fire door to be fitted at the entrance if the front door opens onto a communal area such as a corridor.

FD30 fire doors (30 minute fire door rating) should be used for flats.

8. Can fire doors be painted?

Although fire doors must be fitted with fire rated hinges, locks and hardware, they do not need a special type of paint. You can paint fire doors using regular decorative paint or varnish without damaging their performance. Avoid using heat or chemical paint strippers if the intumescent seals are in place. Also avoid painting over any hinges, hardware or seals.

There is no need to compromise on style and decoration with fire doors. Choose from a wide range of glazing and finishing options including real wood veneer, Formica laminate or paint. Our fire doors can even be pre-painted in any RAL colour of your choice, saving time and hassle and giving a professional finish.

9. Can fire doors be left open?

Fire doors can only be left open if they are held open in a legal way, such as with a fire door retainer or a hold open free-swing door closer.

It is dangerous to ‘prop’ or ‘wedge’ open fire doors. Fire doors are fitted with self-closing devices so that if a fire breaks out, they close and will perform as intended. If a fire door is wedged open, it will not slow or stop the spread of fire. Using a fire door retainer or free-swing door closer will ensure that in the event of a fire the fire door will still automatically close, ensuring fire safety is maintained.

Fire doors can be heavy and cumbersome to operate. They can also cause accessibility issues in some buildings. Fire door retainers, like Dorgard, are a practical and legal solution to this issue. A Dorgard Fire Door Retainer can easily be fitted to an existing fire door and will hold the fire door open legally until it ‘hears’ the sound of your fire alarm. When the alarm sounds, Dorgard will release the fire door, allowing it to close, stopping the spread of fire. Fire door retainers can also help to improve ventilation.

10. Who can fit fire doors?

Fire doors must be fitted by a competent individual. You should ensure that the person fitting your fire doors has had the relevant training to do so. Whatever the rating of a fire door, if it is badly fitted, it may not withstand a fire for any more than 5 minutes. There are legal requirements and specifications as set out by building regulations governing the installation of fire doors. The gap between the fire door and frame, for example, should be between 2 and 4mm. These specifications can be difficult to meet unless installation is by someone with experience and joinery skills.

The regulations around the fitting of fire doors can be confusing. Code of Practice for Fire Door Assemblies does not specify that any particular certification is required to install a fire door. However, The Fire Safety Order states that they should be installed by a competent person. That is someone with sufficient training and experience, qualifications, and knowledge.

Using a professional fire door installer will give a Responsible Person or homeowner peace of mind that the fitting has been carried out correctly and that the fire door will perform as it should in the event of a fire.

Emergency Lighting – A Guide

Emergency Light - A GuideSafelincs operates a fire safety forum where people’s fire safety questions are answered by professionals. One of the frequently raised topics has been Emergency Lighting. To give you a broader understanding of emergency lighting, this blog compiles the typical queries and answers raised through the forum.

What is emergency lighting?

Emergency lighting is lighting that comes on when there is a mains power failure. Emergency lights are powered by rechargeable backup batteries which are either located inside the emergency light or in a central battery location with connections running to each emergency light. Emergency lighting is a general term and is sub-divided into emergency escape lighting and standby lighting. Standby lighting is used to continue normal work during a powercut and, as it is not a legal requirement, is not covered in this guide.

What is emergency ESCAPE lighting?

Emergency escape lighting comes on automatically when the mains power fails and gives off sufficient illumination to enable occupants and visitors to evacuate the premises safely.

Emergency escape lighting itself is sub-divided again into

  • open area lighting (bulkheads and other emergency lights)
  • escape route lighting (typically illuminated fire exit signs with a running white man on a green background)
  • high risk task area lighting (to allow the shut down of dangerous processes)

Publicly accessible buildings as well as most businesses are required by law to provide emergency escape lighting.

What key types of emergency lights are there?

There are two key types of emergency lighting: maintained and non-maintained.

Maintained emergency lights stay on constantly at all times and stay lit for the minimum emergency duration (usually 3 hours) after a mains failure. Maintained emergency escape lights are used in places of assembly like theatres, cinemas, entertainment halls but also shopping centres and similar venues. They allow the public to familiarise themselves with emergency routes and have the advantage that any failure of the emergency lighting bulbs can be spotted immediately.

A non-maintained emergency light will only light up in the event of a mains power failure and will also stay lit for the minimum emergency duration required. Non-maintained emergency lights are likely to be found in offices, shops and factories.

 

Does all escape route lighting have to be illuminated?

If sufficient open area emergency lighting is in the vicinity of a fire exit, non-illuminated fire exit signs can be sufficient in locations of minor importance. Photo-luminescent  fire exit signs would be preferable in this case, although it has to be ensured that sufficient light is reaching the photo-luminescent sign to ensure it is ‘charged’ at all times.

Considerations

British Standard BS 5266-1: 2011 provides clear guidelines about the design and installation of emergency lighting. It should be remembered that the British Standards specify the best practice for standard situations, however, a higher standard may be required for a particular installation.

The actual degree of illumination should be closely related to the nature of both the premises and its occupants.

Special consideration should be given to homes for the elderly, hospitals, crowded areas such as pubs, discos and supermarkets and to whether or not the premises are residential.

Borrowed lighting may be suitable in small premises (eg small shops) where there is light coming into the building from a dependable outside source, e.g. street lamps and will adequately illuminate escape routes. Alternatively, single ‘stand-alone’ escape lighting units may be sufficient in small premises and these can sometimes be combined with exit or directional signs.

An emergency lighting system should be installed by an electrician who specialises in emergency lighting.
They would need to be conversant with BS 5266-1- 2011 Emergency lighting-Part 1: Code of practice for emergency lighting of premises.

The question of the requirement for emergency lights in schools is a bit of an anomaly.
As a school is only occupied during the hours of daylight, emergency lighting is not therefore required. However, should the school be used out of hours, in the hall for example, then emergency lighting should be installed in the hall and the exit routes from it. The ‘responsible person’ should have the final say on this and might want to consult the local fire officer.

Toilet facilities for use by disabled people and/or any multiple closet facilities without borrowed light should have emergency escape illumination from at least one luminaire. Organisations may have to provide emergency escape lighting in each cubicle if there is no borrowed light.

What are the rules for rented properties?

For residential properties landlords are deemed to be the ‘responsible person’ for all fire safety and emergency lighting.

Single occupancy houses and houses of multiple occupancy up to two storeys high only need conventional lighting, whereas three and four storeys may require emergency escape lighting if the escape route is complex and there is no effective borrowed light.

Bedsit houses of multiple occupation of one to four storeys (with individual cooking facilities within bedsits) require conventional lighting and emergency escape lighting if risk requires such or there is no effective borrowed light. Bedsit houses of multiple occupation of five or six storeys with individual cooking facilities within bedsits require conventional lighting and emergency escape lighting

Two, three or four storey houses converted to self-contained flats require conventional lighting and emergency escape lighting if the fire risk assessment requires it.

Five or six storey house converted to self-contained flats require conventional lighting and emergency escape lighting. Importantly, common escape routes should be well lit.
There are guidelines to help understand the provision required and landlords need to be aware of their responsibilities to carry out a fire risk assessment, and make sure their property has adequate and appropriate fire safety measures in place.

How do you maintain emergency lighting?

Emergency lights have to be tested regularly unless they are self-testing emergency lights.

Emergency lights with internal backup batteries display a small green LED that indicates that the internal battery is being charged. Older models may have a red light. However, you still have to check the function of the emergency light regularly, as the LED only confirms that the unit charges rather than that the battery will last the full period required or that the bulb is in working order. 

All emergency lighting systems must be tested monthly. The test is a short functional test in accordance with BS EN 50172:2004 / BS 5266-8:2004.
The period of simulated failure should be sufficient for the purpose of this test while minimising damage to the system components, e.g. lamps. During this period, all luminaires and signs shall be checked to ensure that they are present, clean and functioning correctly. Emergency lighting key switches are available and allow for the interruption of the power to the emergency lights without affecting the power supply to the normal lighting circuits.

A test for the full duration (usually three hours) of the emergency lights must be carried out once a year. The emergency lights must still be working at the end of this test. The result must be recorded and, if failures are detected, these must be remedied as soon as possible.
Any batteries that do not last three hours should be changed immediately.
Life expectancy will vary depending on the make of the battery – with some makes it is four years, some five years. When the life expectancy date expires the batteries should be changed. It is a good idea that when a battery is changed the date of installation is written on the battery for future reference. Safelincs supply spare batteries.

If the fitting has a fluorescent tube the life will depend on whether the unit is maintained or non-maintained. Safelincs recommends that lamps in maintained bulkheads are changed every six months. If a fluorescent lamp has blackened ends / starting to turn black the tube needs replacing.

The occupier/owner of the premises should appoint a competent person to supervise the testing of the system. This person shall be given sufficient authority to ensure the carrying out of any work necessary to maintain the system in correct operation. Competent can be defined as someone who has sufficient training and experience or knowledge and other qualities that allow them to maintain the system properly. The level of competence required will depend on the complexity of the situation and the particular help that is required.

From a practical point of view, a normal caretaker would be able to use a test key to remove power from emergency lights and ensure that the emergency lights stay on the required period. When it comes to repair of failing emergency lights it would most likely that an electrician would be needed unless the caretaker has sufficient qualifications to replace batteries and lamps.

It is important, though, that all tests are recorded in the fire safety log book.

The longevity of emergency lights is better if lamps are changed before they are fully failing. However, this recommendation probably only applies if an organisation has a contractor for the maintenance of emergency lighting and the costs of a call-out were to be substantial. In such a case pre-emptive maintenance (changing while the light is still working) makes sense.

In the long run LED light are more economical than fluorescent tubes as they save electricity not only when the light is on but even during the trickle charging of the batteries. However, the real saving from LED emergency lights comes from not having to replace the tubes on a half yearly or yearly basis. The LEDs will last a lot longer, hence saving costs for maintenance call-outs and replacement tubes.

Many systems will have fish tail key switches in the power supply leading to suitable groups of emergency lights so that you don’t have to switch off the power at fuse level when you want to check them. If you have a system that can only be tested by switching the lighting power supply off altogether you would only be able to do your tests when the building is empty and if you have suitable portable light or suitable daylight in all locations you are checking. If you have dangerous processes in your company lighting might have to be on all the time, so that a central switch-off would be inappropriate.

 

Extinguisher run over by van – still pressurised!

We were always convinced that our P50 service free extinguishers made from a Kevlar-type aramid were almost in-destructable. Nevertheless, when one of our engineers was visiting one of our customers, a refinery on the east coast, he was surprised when he was handed a fire extinguisher that had been run over by a van and that it was still fully pressurised!

crushed-p50-1crushed-p50-2crushed-p50-3

This is not that surprising when you know that 1 in 500 of these extinguishers are tested by pressurising them 12,000 times from zero bar to 25 bar. And after they have undergone this harsh test, they are crushed flat by a steel blade before being re-inflated without being allowed to leak at 55 bar!

The P50 service free extinguisher is suitable for the harshest of environments, including outdoors.

BS 5839-1 fire alarm system standard explained

fire-alarm-panel-kitsBS 5839 Part 1 ‘Fire detection and fire alarm systems for buildings. Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises‘  is the key Standard for commercial fire alarm systems with central control panels. It helps customers and installers to specify, design, install and maintain fire alarm systems.

It is a substantial document and to help our customers find their way through it we have created a summary of the Standard. The summary covers:

  • Why might I need a fire detection / fire alarm system for my premises?
  • What are fire detection and fire alarm systems?

What To Do If Your Clothing Catches Fire

According to statistics published by the East Sussex Fire and Rescue Service in 2012, around 80 people die each year in in the UK after their clothing catches fire.

If your own clothing catches fire you should take the following course of action:

  • STAY where you are—moving or running feeds air to the flames and worsens the fire.
  • DROP to the floor—if you stand up, the fire can burn your face. Fold your arms high on your chest to protect your face.
  • ROLL slowly on the floor or ground, in a rug or blanket if you can.
  • COOL off as soon as possible with water for first and second degree burns. *

If you are in the position of helping somebody else whose clothing has caught fire you should apply the steps above. In addition there is one type of fire extinguisher that can be recommended for such a situation. See the video.

The Jewel E-Series Water Mist Fire Extinguisher is a new type of extinguisher, which works by dispersing microscopic ‘dry’ water mist particles to suppress fires and extinguish burning materials, The speed at which it takes effect, combined with the rapid cooling it induces, make it the perfect extinguisher to have to hand should a fire of this nature break out.

Jewel E-Series Water Mist Fire Extinguishers are the first broad-spectrum fire extinguishers. They can be used on almost every common fire including deep fat fryer fires. They are perfect for kitchens, as they contain no harmful substances and leave no residues. The extinguisher’s supersonic nozzle disperses microscopic ‘dry’ water mist particles to suppress fires and extinguish burning materials. The 35kV dielectrical test ensures that the extinguishers can be safely used near electrical equipment.

*In a serious fire room temperatures in a fire can be 100 degrees at floor level and rise to 600 degrees at eye level. This heat can melt clothes to a victim’s skin. Never peel the clothing off – leave the treatment to medical professionals.

Long-term effects of CO poisoning

One of the speakers at the launch of Carbon Monoxide Awareness Week at the House of Lords in November 2012 was Dr Steven White. He gave a very interesting presentation on the long-term effects of carbon monoxide poisoning, some of which are only recently being fully realised.

Dr White has co-written a factsheet that is published on the website of Headway, the charity that works to improve life after brain injury. With Headway’s permission we reproduce a short extract here.

Like other types of anoxic brain injury, acute CO poisoning may lead to quite severe long-term neurological problems, with disturbances in memory, language, cognition, mood and behaviour. The damage to the basal ganglia, which is a particular feature of CO poisoning, may lead to a movement disorder resembling Parkinson’s disease.

An unusual feature of acute CO poisoning is the delayed deterioration in neurological condition which may be seen in some cases, occurring anything from a few days to as long as five to six weeks after the initial exposure. The reason for this is not entirely clear, but changes in the white matter of the brain seem to be involved. It has been suggested that these may result from demyelination, in which there is loss of the fatty, insulating myelin sheath of the nerve axons, therefore impairing their ability to conduct electrical nerve impulses.

Chronic CO exposure

Chronic (persistent and long-term) exposure to lower levels of CO, as can occur with faulty domestic boilers, may go unrecognised. The symptoms include milder versions of those seen in acute CO poisoning, with headache, nausea, dizziness, light-headedness, fatigue and sleepiness, difficulty concentrating and memory problems, as well as changes in mood.

People may be aware that something is wrong, but be unable to identify exactly what is the matter, or may attribute the problems to overwork, stress or depression. If symptoms disappear while away at work, reappearing on returning home, or if other people in the same premises develop similar symptoms, it may become more obvious that there is an environmental cause.

Although most people seem to recover following chronic low level CO exposure when the source is removed, it can also lead to anoxic brain injury. There have been some documented cases of subtle Magnetic Resonance Imaging (MRI) abnormalities and long-term neuropsychological effects.

Treatment of CO poisoning

Treatment of acute exposure to CO involves immediate removal from the source of the poisoning and administration of 100% oxygen, together with general supportive medical care.

Hyperbaric oxygen therapy is sometimes advocated for severe cases of CO poisoning and involves giving pure oxygen at increased pressures in a hyperbaric chamber. It has been suggested that this may improve the long-term neurological outcome, although it remains controversial. Hyperbaric oxygen therapy is a specialised technique, which is only available in a few centres. It may also be associated with complications of its own and it is not used routinely.

Extending Ei140 + Ei160 series smoke alarm groups

Many homes and small businesses are equipped with mains powered smoke alarms to BS5839 part 6 Grade D. These alarms are usually linked with cable and have to be installed by electricians. When increasing the number of smoke and heat alarms at a later date, it is costly and disruptive to run extra cable to the additional alarms, decorations are damaged and dust is created.

With the Aico Ei140 series (Ei141, Ei144, Ei146) and the Aico Ei160 series (Ei161, Ei164, Ei166), adding more smoke alarms to the group of alarms can be very simple using radio-interlinking.

Just one existing smoke alarm is taken off the ceiling and its existing base plate replaced with the RF base plate Ei168. This exchange, while very swift and simple, should be carried out by an electrician. The old alarm then simply slots onto the newly fitted base plate. Now you can install any of the radio-interlinked smoke alarm ranges from AICO/Ei in the additional rooms you wish to protect. The new radio-linked alarms will then communicate fully with the old system. This means that if any of the smoke alarms goes off (old or new alarms), the rest of the alarms will sound an alarm as well.

You have three choices to achieve this extension with radio-interlinked smoke alarms:

1) Install more mains powered alarms together with RF base plates. Their electrical power supply can be drawn from the nearest light fitting. This solution will require an electrician for all the work. However, this is a solution that will guarantee the Grade D rating of your installation. There is obviously no cabling required between the units, as the radio signal will communicate between the new alarms and, through the single converted old smoke alarm, with the old system. There are additional add-ons you can include in this system, such as RF manual break points and handheld controls for testing and, in the case of the Ei160 series, even for silencing and to locate the source of an alarm.

List of Alarms and add-ons available:

Series installed already Mains powered RF Smoke alarms available Manual break points available (optional). Wireless and 10 year battery Handheld controls available (optional)
Ei140 Ei407 Ei410TRF handheld test fob (tests interconnection, only)
Ei160 Ei407
  • Ei410 handheld test, hush and locator

2) If you want to save the cost for the electrician and want to speed up the installation process, you can install battery operated radio-interlinked alarms. One of the radio-interlinked families is the Ei600 series, which comes with a sealed-in ten year power supply. This system is usually accepted as a Grade D system, even though formally, as it does not contain mains power, it is not classified as a grade D system. If you have to satisfy a Building Inspector or the fire service, it makes therefore good sense to get their agreement before installing the system.

3) If you are not required to install in accordance to BS5839 Part 6 Grade D (eg older houses built prior to introduction of Building Regulations), you can also use radio-interlinked smoke alarms with alkaline backup batteries which must be replaced every year or two. This is of course the cheapest way of expanding your existing smoke alarm system. Again, all alarms will go off together, both the new as well as the old alarms.

What power consumption do emergency lights have?

When comparing power consumption of emergency lighting, and more specifically comparing LED lighting with standard lighting, it is important to understand some of the terms used and what they actually mean in this context. Sometimes you will see the power consumption documented in W (Watts) and sometimes it will be stated in VA (VoltAmperes). Whilst this looks confusing, it is comforting that both terms are actually identical. Multiplying the Voltage (V) of the electrical supply with the Amperage (A), which represents the current flowing through the light, gives you VA (VoltAmperes) which represents power consumption and is actually the same as the ‘Wattage’ (W). So VA equals W; they are just different ways of saying the same thing.

For this blog we will be comparing a CS8 maintained emergency bulkhead with an X-GSA LED maintained emergency bulkhead as they are very similar units, although they have a very different power consumption (also the CS8 produces light output of  100 lumens, whilst the X-GSA produces a slightly lower 85 lumens. This difference, though, is negligible.).

The CS8 contains an 8W T5 lamp which, as the name suggests, consumes 8 Watts. The ballast (the electronics that run the unit and the trickle charge for the backup battery) consumes 12 Watts, which means the CS8 in maintained mode consumes 20W.

The X-GSA contains 12 white LEDs which together consume 0.9W. The ballast consumes 2.6W, which means the whole unit in maintained mode consumes 3.5W.
That is a difference of 16.5W, which is huge when you consider that maintained lights are lit constantly. So, a CS8 in its maintained mode is consuming over 5 times more energy every hour than the X-GSA!

It is also important to know that LED emergency lights last substantially longer than fluorescent tubes. An LED bulb will last over 5 times longer than a traditional fluorescent light.

Generally speaking LED emergency lighting is more expensive than the traditional equivalent, but when you factor in the substantially lower power consumption and the lower maintenance needs of LED lights, they are actually more cost effective in the long term.
