What power consumption do emergency lights have?

Tuesday 26th June 2012

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.

Replacement of old Kidde smoke alarms

Monday 11th June 2012

As well as testing your smoke and heat alarms on a regular basis, it is important to make a note of when the units actually need to be replaced. Studies have shown that the functionality of smoke and heat alarms can start to deteriorate when they reach a lifespan of 10 years. Each smoke and heat alarm should have a “replace by date” visible on the outside of the unit and we recommend that you adhere to this guideline.

When replacing a smoke alarm it can be quite difficult to recognise a suitable replacement product. In some cases, you may find that the current alarm model has been discontinued. With battery operated alarms, as there is no wiring in place, it is much easier to replace the unit for another smoke alarm with like-for-like features. Mains powered alarms are hard wired and are most likely interconnected during installation. It is because of this that finding replacement detectors can be difficult.

Working with Kidde Safety Europe, Safelincs are able to provide a list of mains powered discontinued Kidde smoke and heat alarms, along with their suitable product equivalents.

Discontinued Alarm	Replacement Alarm
123/9HI	KEKF10
123i	KEKF10
123/9HILL	KEKF10R
223/9HI	KEKF20
223/9HILL	KEKF20R
1275H	KEKF10
323/9HI	KEKF30
323/9HILL	KEKF30R

The new alarms will interlink with other, still working units of the previously installed smoke alarms. This means that there is no need to replace all of the units within a system if only some of the installed detectors have reached the end of their recommended lifespan. All new mains powered smoke and heat alarms are provided with a mounting bracket and a wiring connector. It is important to note that you need to replace the existing mounting base and re-connect the wiring to fit the new units. With any mains powered alarms, all electrical work should be carried out by a qualified electrician.

Safelincs offer a smoke alarm reminder service which allows customers to be notified when their smoke and heat alarms are due to be replaced, when the batteries need to be changed and reminds customers to test their alarms on a regular basis. The service is completely free and customers can choose if they wish to be reminded by email, SMS text message or by Twitter.

New Evacuator Site Alarms

Monday 14th May 2012

Recently Safelincs added several new site alarms to their range. These included the Evacuator Site Guard call point and push button alarms, the Evacuator Tough Guard and the newly released Evacuator Tough Guard Wireless.

All four of these alarms are designed for use in building and construction sites, temporary marquees, camp sites, markets etc. where installing a permanent fire alarm system would be impractical and unnecessarily costly.

The Evacuator Site Guard is ideal for less harsh environments, such as camp sites and markets, while the Evacuator Tough Guard is perfect for busy building and construction sites where it may encounter water, dirt, dust and debris. The Tough Guard features an IP56 rated weatherproof enclosure that copes with harsh weather conditions and the occasional knocks and bumps it may have to endure.

These battery powered alarms can be used as standalone units or linked using 2 core wire. Running interlink cables all over a busy construction site may not be safe or practical, and this is where the new Tough Guard Wireless comes in. The Tough Guard Wireless has all the strength, durability and weatherproof protection of the standard Tough Guard with the added benefit of completely wireless interconnection to other Tough Guard Wireless units. The amazing 18,000m wireless range, long life battery and extremely loud 118dB sounder make these alarms an essential piece of safety equipment for any situation.

Which type of smoke alarm should I use?

Tuesday 8th May 2012

Smoke alarms are the most essential components in any fire safety strategy, whether in commercial or domestic properties.

There is a wide range of smoke alarm models available designed to suit various circumstances. It is therefore important to ensure that you purchase the correct model for your requirements, in order to ensure your smoke alarms operate as efficiently as possible.

Below is a summary of the various smoke alarm models featured on our website:

– Optical smoke alarms are suitable for general use and are especially suitable for detecting smouldering fires caused for example by smouldering soft furnishings. They are also not too sensitive to false alarms from burnt toast, making them ideal in hallways (near kitchens), living rooms and bedrooms.

– Ionisation smoke alarms are able to detect the change in the behaviour of the air in case of a fire. Fast flaming fires, such as burning waste paper baskets, are easily detected by ionisation smoke alarms and we recommend ionisation smoke alarms for use in offices or on landings. Please note that ionisation smoke alarms contain a small amount of radio-activity. If you wish to avoid this, choose optical smoke alarms instead.

– Heat alarms are designed to detect the increase of temperature caused by a fire and do not cause false alarms. They are especially useful in dusty or smoky areas, such as kitchen and garages. They do, however, not cover very large areas, so cannot really be used for larger parts of a building.

– Multi-sensor alarms combine the features of optical and heat alarms, resulting in rapid fire detection and a reduced risk of false alarms. They are suitable for living rooms, bedrooms, hallways and landings but should not be used in kitchens.

If you require further advice on which smoke alarm design is suitable for you, please don’t hesitate to contact us today. We also publish a guide on the different smoke alarm technologies.

For warehouse areas and industrial properties we offer more fire detection technologies and central alarm panle systems.

Why are Fire Door Closers Important?

Thursday 3rd May 2012

In order for fire doors to function properly, they should remain closed when the door is not in use. As obvious as this sounds, in a busy office building it can be difficult to ensure that fire doors are being closed. Therefore automatic fire door closers are installed to ensure that, after a door is opened, it naturally returns to a closed position where it can offer the maximum fire safety.

Fire door closers are a legal requirement in most settings

How do fire doors closers work?

Door closers work by using the energy built-up when opening the door, to close it. Fire door closers have different closing strengths depending on the weight of the fire door. The closing strength is otherwise known as the EN power size. Smaller and lighter fire doors do not need as much strength in the fire door closer to shut the door. Many door closer models have an adjustable power size. The configuration of the door closers will also depend on the design of the door (inward/outward closing).

How do I check my door closer is working?

This fire door maintenance checker is a useful guide for checking all parts of your fire door to make sure they are compliant and operational. An unlatched or non-operational door closer will not shut the fire door if a fire breaks out. This could have disastrous consequences.

Which fire door closer do I need?

There are a number of different types of fire door closer available including closers that are even concealed within the doors themselves. Free-swing closers enable the doors to be held safely in an open position or to swing freely on the hinges. This can help to improve accessibility, particularly for anyone with mobility difficulties or in busy areas. In the case of a fire, the fire alarm will trigger these hold-open devices and allow the door closer to close the door.

If you are not sure which fire door closer you need, compare features and prices in this overview of fire door closers. Alternatively, contact our customer support team on 0800 612 6537.

Break the Fire Triangle, Kill the Fire

Thursday 5th April 2012

What is the fire triangle?

The fire triangle is made up of three elements, which are the three components needed for a fire to start and burn: fuel, oxygen and heat. Removing one of these elements will prevent the fire from spreading and causing irreversible damage. Fire protection equipment will help you and your staff break the triangle, reducing potential risks of damage to a building or loss of life.

The three elements of fire explained

Heat

Heat must be present for a fire to ignite. Flammable materials constantly release flammable vapours, where heat is present, these vapours will ignite and start to burn.

Once a fire has started, heat from the fire will dry and remove moisture from surrounding materials (fuel), which results in the fire spreading.

Fuel

A fire needs fuel to burn and feed it. Fuel can be in the form of any combustible material such as paper, wood, textiles, oil, liquids etc. Removing the fuel will prevent a fire from spreading or starting in the first place.

Oxygen

Without oxygen, a fire cannot ignite and continue to burn. Oxygen is all around, making this one of the most significant factors of the fire triangle.

How does fire safety equipment break the fire triangle?

Installing fire safety equipment, such as fire extinguishers and fire blankets, can help stop a small fire from spreading. Fire blankets deprive the flame of oxygen by covering it, killing the fire.

Many fire extinguishers, such as foam and water fire extinguishers, work in the same way; either by covering the flame and its fuel to remove oxygen, or by cooling the fire and any nearby fuel, reducing the risk of the fire spreading. Water Mist fire extinguishers deploy a cooling mist, and are safe to use on live electrical equipment up to 1000V, making them an ideal extinguisher for businesses, education, hospitality and the care sector.

Although fire safety equipment can be a useful tool in stopping a small fire from spreading, a fire should only be tackled if staff are trained to use them, and are confident in what they are doing.

Water Mist fire extinguishers are ideal for businesses, education, hospitality and the care sector.

Fire Safety Training Courses

To prepare your staff to effectively extinguish fires, there are a variety of on-site fire safety training courses available. This includes fire safety awareness and fire warden training, as well as evacuation training to ensure that staff can escape to a place of safety until the fire is under control. These training courses will not only reduce the risk of a fire breaking out on your premises by enabling staff to reduce the risk of fire in their daily duties, but also improve responses and outcomes in the event of a fire.

Preventing a fire from starting in the first place is always the best form of fire safety. Encourage staff to keep an eye out for potential causes of fire, such as faulty electrical equipment or hazardous materials, and use flammable liquid storage cabinets to reduce the risk of these flammable liquids igniting.

All staff must be trained to safely evacuate to a place of safety in the event of a fire.

Employers are required by law to ensure that all employees receive adequate fire safety training. Employers must also provide adequate equipment, such as evacuation chairs and evacuation sheets, to ensure everyone in the building can safely evacuate.

FAQs

Q. What element of the triangle does a fire blanket remove?

A. Fire blankets suffocate the flame, removing oxygen from the fire.

Q. What do foam extinguishers remove from the triangle?

A. Foam extinguishers work in multiple ways to fight fire – the foam spray covers the flame and its fuel to remove oxygen, while also cooling the flame to extinguish it.

Retrofitting or Replacing Fire Door Seals

Tuesday 20th March 2012

Following a fire risk assessment, doors are sometimes re-designated as fire doors if the door and frame are substantial enough to be justifiably counted as a nominal fire door. The same applies to older fire doors which do not follow the latest specifications. In these cases, fire door seals are retrofitted, and to avoid having to cut a rebate in either the door or the frame, surface mounted fire door seals can be fitted. These are stuck to the frame or door with their self-adhesive backing and sometimes nailed as well to give them increased longevity.

Where a fire door rebate already exists, or the existing rebated fire door seal has been damaged, rebated intumescent fire door seals can be fitted.

We offer a range of fire door seals: fire only, or combined fire and smoke. Both variants contain intumescent material that swells if a fire breaks out to seal the gap around the fire door. Seals that cover smoke also contain a brush-type smoke seal to stop smoke travelling through the gap before the intumescent material expands. There are some applications where a gap should not have smoke seals: e.g. if the fire door has been installed on the exit of a room which has no smoke detectors on its own. In this case, the fire alarm system can only be triggered if smoke can leak out around the fire door and set off the fire alarm system in the circulation spaces, but these cases are quite rare.

Fire door seals are fitted on three sides of a fire door with the gap underneath the door not being covered, though there are products available to prevent smoke from escaping under doors if necessary.

If new fire door seals are fitted for the first time, make sure that fire door hinges, fire door closers and, where necessary, intumescent door lock protection are fitted as well.

CO Alarm for Caravans and Motorhomes

Friday 16th March 2012

Prepare for the summer season by installing a CO alarm for caravans. Because caravans are a confined space, the potential for the build-up of deadly carbon monoxide gas is greater. If you have already fitted a CO detector, ensure that you carry out your pre-holiday safety checks. This should include checking or replacing the batteries and testing smoke, heat and CO alarms. It is also advisable to check when your alarms need replacing. Sensors in these types of alarms become less effective over time and will need to be replaced after 10 years.

Free Water Mist Extinguishers for Qwackers Pre-School

Friday 2nd March 2012

Qwackers Pre-School in Alford, Lincolnshire has been part of the life of generations of local people. It started off in a hall at the side of a babbling brook where ducks swam. The group then moved to a second-hand prefab building that was erected on the site of the John Spendluffe School.

This building has served a good purpose but with many years of wear and tear it became apparent that it was no longer viable to repair the structure any longer. After several years of campaigning Qwackers have now moved into a brand new building on their old site.

We always like to support local causes and as Qwackers is a registered charity we wanted to show our support by installing new extinguishers for them and maintaining the extinguishers on a yearly basis in the future completely free of charge.

We chose to install Water Mist extinguishers, which when deployed will leave no residue and will not cause water damage as with conventional water extinguishers. The Water Mist extinguishers are fitted with a supersonic nozzle, creating a microscopic mist curtain. The water mist removes oxygen from the fire and also cools the material that is alight, reducing the chance of re-ignition. Because the extinguisher is creating a fog rather than a jet, the water mist extinguishers are ideal for schools and nurseries, as children cannot hurt themselves, should they ever set off an extinguisher.

Water Mist extinguishers are also perfect for home, offices, shops and kitchens, and their testing credentials mean they can even be used on electrical equipment too!

What to do with old smoke alarms?

Monday 19th December 2011

Customers ask us occasionally about the recycling of smoke alarms. Here is some information relating to this.

Smoke and heat alarms fall under the WEEE (Waste Electrical and Electronic Equipment) regulations. The biggest burden, with regards to the recycling of these goods, falls on businesses manufacturing, rebranding or importing alarms or any other electrical equipment. Retailers like us have to follow a reduced set of regulations.

Retailers have to pay a fee to be allowed to recommend their domestic customers to drop their old smoke and heat alarms off at local recycling centers (Distributor Take-Back Scheme) rather than returning them to Safelincs for passing on to the manufacturers. As the directive states that the customer should in this case dispose of the old alarm themselves at the recycling centers we could in theory refuse to accept old smoke alarms back from domestic customers. However, we allow customers to send us their old units as a courtesy when they purchase from us.

Ideally, as stated above, domestic customers should drop their old alarms off at their local recycling centers, however, they can also dispose small numbers of alarms in their normal refuse. Quite often customers are concerned that the crossed-out wheelie bin on the back of the alarm means that they must not place the unit in a normal waste bin. This is a mis-understanding, the crossed-out wheelie bin just means that this product falls under the WEEE regulations and ideally should be recycled. Nevertheless, small numbers of smoke alarms are permitted in the household waste. There is currently no differentiation in this respect between the ionisation and other smoke alarms despite the ionisation alarms containing small amounts of radio-activity.

There are WEEE rules that differ for domestic customers and businesses. Business smoke alarm users can drop small numbers of old alarms off at the recycling centre, where the cost for recycling will be passed on to the manufacturers. Business customers can also pass the smoke alarms on to us. We then pass them on to the manufacturers. This is only the case if they buy new smoke alarms from us at the same time or if they bought the units from us in the first place (there are some detailed rules relating to this regulation, which have been left out for simplicity).
