David Leigh of Detectomat UK reviews the potential for Design Conscious Fire Detection solutions using new product and system developments from the Fire industry.

Blending with traditional interiors and keeping up with changes in interior design styles and moods is a challenging task for suppliers of building components. However, a review of the general range of smoke detectors available suggests that this challenge has until recently been totally missed or not taken up by most Fire Detection and Alarm companies! The need for aesthetically pleasing devices is applicable to New Build and Refurbishment or Retrofit applications. In the latter two areas there is also the issue of installation time, access, damage to decoration, ugly surface wiring and general disruption, which can lead to “unhappy clients”! These are the current issues. Facility Managers, builders and developers need a solution to the complex requirements of providing good fire protection whilst at the same time ensuring rapid, cost-effective installation with minimal business disruption. Fire Detection needs to be attractive, complement the dǸcor and avoid the need for ugly surface wiring or damage to decorations from installing concealed wiring.

Standards and the legislative framework

Solutions to the above issues are emerging but, before we review them, we should review the Standards and Legislative environment in respect of Fire Detection and Alarms.

For New Build or Major Refurbishment – Building Regulations Part B covers all the fire detection and protection requirements in any type of dwelling in the UK, with the exception of prisons. Section 1 covers dwellings – including large houses, loft conversions and sheltered housing plus commercial and industrial properties. Section 2 covers HMOs, which are single family residences converted into a number of small flats or bed sitting rooms so that the status changes from a family residence to a multi-person residence.

In respect of Residential New Build, the minimum requirement, as per Building Regulations, is 240vAC interlinked self-contained alarms or a suitable BS5839 part 1 or part 6 solution. However, it should be noted that BS5839 is a Code of Practice, which has scope for implementation with variations subject to individual site by site Risk Assessments and agreement by the Designer, Installer and end client. Part 1 is a code of practice, which mainly applies to the installation of fire detection systems for commercial and industrial applications. It is considered to be the Bible for the fire industry, including the fire services. Part 6 is a code of practice, which covers a wide range of residential properties from bedsits to castles!

The Fire Services Regulatory Reform (Fire Safety Order) or RRO, which came into effect in October 2006 represents a major Fire legislation change, building on and replacing the 1999 Fire Precautions in the Workplace act, which started the move from prescriptive to risk based assessment. This order, to be policed by Fire Services, is a risk based assessment emphasising fire prevention implemented by responsible and competent persons.

Fire Sytem components and Design Conscious Solutions

A Fire Detection and Alarm system should be appropriate to the task as determined by risk assessment, conform with, relevant BSEN Standards and comply with the Building Regs. There can be many alternative solutions to achieving the cover or level of protection required. However, some are more Design Conscious than others!

For example, most detection and alarm systems require automatic detection and there is a large range of suppliers but most smoke detectors have been designed by electronic engineers with little or no regard for aesthetics. However, products are now emerging, which recognise that aesthetic design is as important as detection performance. And the Designer Range below is such an example, providing self-contained alarms, conventional and addressable detectors with a range of Designer covers and colours -white, black, satin silver or glass to match traditional or contemporary interior designs, see inset-

Intergrated Detector/Sounder/Beacon products and the opportunity to semi-recess detectors as per the earliar picture at the beginning of this article are other areas in field devices, where consideration of aesthetics is coming through in modern designs.

Control and Indication panels are also an area, where size and design are an important factor and here too we’ve seen significant reductions in size over the years with considerably more thought being given to aesthetics as the example inset-

Wire-free Radio as part of a Design Concious Solution

All Fire Systems require an interconnection of the various components including detectors, manual call points, sounders and control panels, which is normally done in electrical cabling or commonly termed hardwiring. Installing cables in existing buildings is time consuming and presents access issues, damage to decoration, ugly surface wiring and general disruption, which can lead to “unhappy clients”! All of these issues can be resolved or avoided with Wire-free or Radio Fire Alarms providing a far more design concious solution and “happier clients”!

Radio, as a communication medium has been available for many years at a high cost. However, application of the latest technoledgy has produced wire-free systems, which can provide cost-effective solutions for systems as small as two self-contained alarms in a residence or as large as a shopping centre. Systems currently available range from networked wire-free, Analogue Addressable systems to radio alternatives to single Addressable loop or Conventional panels as inset-

Hybrid or Gateway systems have also emerged. This is where a hardwired Analogue Addressable system can be extended or initially configured with one or more Radio Gateway. If a Facility Manager is faced with the need to extend fire detection coverage to comply with an updated Fire Risk Assesment this can provide a particulary useful and cost-effective solution. Facility Managers and Owner/Managers want the highest level of safety for their building occupants but they also want to avoid disruption and damage to the building decoration and fabric, which only a wire-free solution can provide.

The need to avoid disruption and damage is wide reaching and as a consequence the demand for wire-free solutions is significant as a proportion of the overall market and growing at a rapid rate. Listed buildings are of course one of the most sensitive areas.

Case Study – RRO and a Gospel Church Listed Building

When Avon Fire and Rescue ruled that their existing fire protection was inadequate the Gospel Church Hall in Bath chose a wire-free, radio fire detection system. The introduction of the RRO and the results of a risk assessment and fire audit persuaded the Church administrators to bring the premises up to standard.

The Church is a Grade II listed building, which meant that the potential damage from the installation of a hard-wired system was unacceptable and a wire-free solution would have to be sought. The Hall is in continuous use 7 days a week by members of the public for various clubs, meetings and activities so there was a real need to avoid disruption, mess and dust, another benefit of using a wire-free solution i.e. minimum installation time and disruption!

Having considered various alternative solutions, the church selected a wire-free fire detection system because it offered a cost-effective solution for the task. They also choose designer optical smoke detectors with integral sounders, which complement the churches interior design see inset-

And because all the sounders were integrated within the detectors the system did not require the installation of sounder circuits. In a listed building this was a significant benefit i.e. no need for wiring additional sounder circuits, avoiding damage to the fabric of the building. The wire-free system was installed within 8 hours resulting in little disruption to the Church Hall’s activities. And because cabling was avoided, labour costs were reduced to the minimum resulting in considerable financial savings. This example demonstrates the clear benefits from using radio wire-free fire alarms to provide fire protection in listed buildings and the potential for replication is vast.

In conclusion, Design Conscious Fire Detection is now available through a combination of Designer detector covers to complement contemporary or traditional designs, modern panel designs and wire-free radio systems to reduce installation time, damage to decoration, ugly surface wiring and general business disruption.

Polypipe extends Elegance range with release of Ogee Notched profile and soil and vent products

Polypipe Building Products has launched its enhanced and extended Elegance cast iron effect uPVC rainwater system with the addition of the revolutionary notched gutter concept for its new Ogee profile to add to the original and already popular half round profile. The Elegance range has been designed in such a way that each profile in the range utilises a common downpipe, making installation and ordering very simple. In addition it has launched a new range of soil and vent products in a matching cast iron effect finish.

The new notched Ogee profile guttering provides a secure fit and counters the problem of gutters becoming dislodged from their retaining clips during warm weather due to heat expansion, making leaky joints a thing of the past. The leading edge of the gutter is notched and the system uses a flexible band clip to secure the gutter. The lugs on the gutter are simply matched to the band clip and snapped into place.

In addition to the notches, Polypipe has included grooves midway between the notches which act as cutting markers when cutting the lengths of guttering. These benefits, in addition to the lightweight construction of the new guttering system, makes handling, assembly and installation as simple as possible for installers.

Simon Green is Polypipe’s Product Marketing Manager for the drainage and water management side of the business: “We’re excited to be able to extend the Elegance range with the new Ogee profile which closely resembles the profile found on original cast iron installations,” he says. “This will make it easy to preserve the traditional look of a period home when replacing the original guttering, but with the knowledge that it will give a more secure fit, be simpler to install and far lighter than the original.”

The new soil and vent range is based on the Polypipe 110mm soil pipe, supplied in 3 metre lengths with a selection of sockets, bends and a vent terminal. The range uses Polypipe’s popular push-fit system, again for quick and easy installation.

Full details of the new extended Elegance rainwater, soil and vent range can be found on its own dedicated web site at www.polypipe.com/elegance and the new system is available from merchants now. Alternatively you can call 01709 770 000 quoting reference “ElegancePRA” and request information, a product leaflet and price list.

Heron Tower is undoubtedly set to become one of the best known landmarks on the central London skyline. The 230 metre high, 46 storey building is a glass and stainless steel clad structure on which the VMZINC PLUS standing seam system has been used on the two main roof areas. It is among the tallest buildings in which the warm roof system has been used, the 'compact roof' approach having been taken in conjunction with Foamglas®.

The roofs occupy the 38th and 41st floors, on which the Restaurant, Sky Bar and external terraces are situated. As VMZINC PLUS needs no supporting ventilation, views over the roofs are not spoiled by unsightly vents across the span.

Precise wind loading calculations were a primary consideration, but at such a height it was just as important that the specified metal presented no visual interference to aircraft. VMZINC’s pre-weathered Quartz-zinc® was a perfect choice as its natural patina continues to develop over time. As a result, zinc also offers an exceptional standard of colour retention, with minimal maintenance requirements.

VMZINC’s Paul Carter added, “Due to the careful planning and regular flow of communication between all parties, the project ran without issue and those that are lucky enough to drink or dine at this landmark building can enjoy uninterrupted views of the London skyline and the zinc roof for many years to come. The installation reflects the highest contracting standards.”

In addition to cellular glass, VMZINC PLUS can be used with mineral wool, PIR and composite insulation boards. 0.7 mm thick panels are available in either straight or curved profile in Natural, QUARTZ-ZINC® , ANTHRA-ZINC® and PIGMENTO® colours. Sheets of up to 13 metres in length can be installed using specially designed clips which do not penetrate the surface. Specialist metal roofing contractor Andy Bell of Bell Zinc and Copper Roofing said of the project, “Working at such height meant that wind rather than rain was the predominant problem. All work was carried out using full restraint harnesses and cargo nets to ensure that nothing could fall from the roof. The VMZINC standing seam system is normally straightforward to fix but in this case, the installation time was considerably longer. The end result, however, is a striking advertisement for zinc”.

Kingswinford-based manufacturer, Elta Fans, has announced the availability of a new brochure on the twin-fan version of its ‘QuietflowDCV’ range. The full-colour, 36-page brochure covers all the products’ features, benefits, specifications, technological improvements and technical data, as well as all relevant current legislation and the role of twin-fan units in providing continuous ventilation. Brochures for the Elta Fan Quietflow SQS and QuietflowDCV Single Fan units are also available.

Twin-fan units are used in various applications that require guaranteed continual ventilation. The two fans are mounted within the same unit, with only one fan operational at any time. The second fan acts as a backup and only becomes operational if the primary fan fails. To ensure longevity, there is a duty share schedule programmed for change every six hours, whereby the operational fan becomes the backup fan and vice versa. Typical applications include hospitals, public buildings, office buildings, toilets or other areas where volatile organic compounds (VOC’s) are present and necessitate extraction on public health grounds.

‘Quietflow’ is the range of acoustically treated, compact units from Elta Fans designed to overcome space restrictions in buildings with low ceiling voids and to provide exceptionally quiet performance when installation in close proximity to the occupants is unavoidable. ‘QuietflowDCV’ is the manufacturer’s affordable solution for ‘demand control ventilation’, providing optimum air quality combined with low energy usage. It does this whilst making significant energy savings through the use of variable speed solutions to ensure the ventilation rate always matches the occupancy rate in order to maximise indoor air quality cost effectively.

QuietflowDCV units are robust, lightweight with low-profile, galvanized steel casing and flame-retardant, Class O-rated acoustic lining – so breakout noise levels are significantly lowered. The high-efficiency, backward-curved, centrifugal impellers are directly driven by an external rotor motor, mounted inside the fan casing and designed to provide reliable, continuous air extraction with a smooth airflow. The impeller axis runs horizontally across the unit, which minimizes the overall height of the unit for ease of fitting in roof spaces.

The three main elements comprise the sensors, zone controller and room controller. The sensors continuously measure and monitor ambient conditions in the conditioned space and provide real time feed back to the zone controller which adjusts the fan speed, modulating the ventilation rate to match the specific use and occupancy of the building. The room controller provides a clear overview of the settings and status, with simple intuitive operation and unobtrusive aesthetic design. All QuietflowDCV units are suitable for 220-240V operation and all the AC-motor specified units operate on 50Hz whilst all EC-motor specified units can operate on 50Hz or 60Hz. They are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance). All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2000.

Thorn’s suspended Planor upgrade uses upcoming technology, the MicroPrism optic, to guarantee lighting quality.

The sleek indirect/direct fluorescent pendant combines T5-16mm lamp technology and a micro prismatic lighting technique that regulates the light through pyramidal prisms and a newly developed surface. This gives 30% more light than its predecessor, while reducing glare and concealing the lamps from direct view. Elegant and technically sophisticated it solves one of those eternal problems – how to give even, yet ‘user friendly’ lighting over an entire desk surface.

Intelligent ‘MiniSensa’ and digital dimming versions deliver light only when it is needed for optimal energy usage. As a result Planor MPT not only provides pleasant illumination, but energy efficiencies according to current regulations.

The minimalist design of the flat silver-grey frame (only 35mm thick) evokes association to the flat screen panel displays of the future, while the use of aluminium and recyclable plastics ensures long life, low maintenance and minimal environmental impact. This makes the Planor MPT series the perfect solution for tomorrow’s office and school environments.

Plant hire firms, builders, contractors, utilities, local authorities and owner operators alike have enthusiastically welcomed the new generation of Dash 4 mini excavators from Kubota (UK) Ltd – Construction Equipment, praising the machines’ unrivalled blend of power, reliability and the very latest technology.

The manufacturer’s new U48-4, U55-4 and KX057-4 models have already been pressed into service following their UK introduction at the company’s Kubota Live! event at Rockingham Castle earlier in 2010.

The machines have built upon the excellence of their predecessors by offering users more strength per pound, thanks to each one’s increased boom lifting force, which has allowed Kubota to step up the weight scale.

The new U48-4 zero tail swing excavator offers 4.7 tonnes of lifting power, combined with the ability to work in confined spaces. This makes it the most powerful zero-tail swing machine in Kubota’s range, while still offering a smooth travel performance.

The Kubota U55-4 tight tail swing machine sees the range breaking new ground with 5.4 tonnes of lifting power, complemented by excellent stability and high performance in restricted areas.

The Kubota KX057-4, meanwhile, hits the 5.5 tonne mark, added to a maximum dig-depth of 3,890mm and an impressive bucket digging force of 4,315kgf.

The machines also offer a host of easy-to-use features and unrivalled user comfort. There is better visibility and a space-age digital display, which indicates fuel level, engine temperature, service intervals, auxiliary circuit oil flow settings and even the machine’s operational history.

Each has a new load-sensing hydraulic system which provides optimum oil flow to each cylinder, offering smooth operation and enhanced fuel economy, as well as an auto-shift system which enables automatic travel shift from high to low, depending on traction effort and terrain.

Their Interim Tier 4 engines have a fuel-saving auto-idle function and can all be serviced from one side, while, on the outside, all three models now feature a new look black cab livery, which will be subsequently rolled out across the rest of the Kubota mini excavator product range, as and when new Dash 4 models are launched.

One of the first companies to invest in the Dash 4s – in this case, two KX057-4 models – was Jarvie Plant Group Ltd, which is one of Scotland’s leading independent hire companies and operates out of seven bases in Central Scotland, including its HQ in Grangemouth, near Falkirk.

The group’s managing director, John Jarvie, said: “We have bought Kubota equipment for many years and are committed to a continual investment programme for our fleet, so it was a natural decision for us to buy the very latest KX057-4 machines.

“Customers these days want mini excavators that are quieter, offer enhanced performance and which are more fuel-efficient. The KX057-4 achieves all of these targets, providing the benefits direct to our clients.”

Further north, in Aberdeen, MTM Construction Ltd bought a Kubota U55-4, which has been added to its fleet in order to answer the growing need for machines capable of working in confined spaces.

Bill McDonald, plant/transport manager for MTM Construction, said: “We’re very pleased with the machine, it’s the biggest Kubota mini that we’ve got and gives us a powerful excavator for tight areas.

“It also accommodates a wide range of attachments and you can pre-set the oil flow so you don’t have to get a fitter to adjust it for you when you use another attachment.

“We’re always keen to buy Kubotas because they’re extremely reliable. We like to keep them for a number of years and we’re confident we’ll get good service from this one.”

All three new Dash 4 machines were sold by Young Plant & Equipment Sales, based in Doune, Stirling, which is one of the largest compact equipment sellers in the world and one of Kubota’s largest dealers for mini excavators.

It has sold Kubota minis for 31 years, but managing director Brian Young said that the host of upgrades incorporated into the Dash 4s are as impressive as he has seen.

He said: “Our customers are thrilled with what they are getting with the Dash 4s, and still know that, like all Kubotas, they are reliable, need minimal servicing and hold their value.

“The differences between the previous Dash 3 models and the new Dash 4s are significant and once again show how far in front Kubota is compared to other manufacturers. If you take the U48-4, for example, not only have you got a bigger machine with the same footprint, everything is well thought-out and the digital control layout is revolutionary.

“It’s products like this which make me glad that we sell Kubotas and I can guarantee that whatever Kubota does today, the rest of the industry will be doing it tomorrow.”

Like other Kubota mini excavators, the Dash 4s are fitted with their unique key-based 'ANTI-THEFT' system as standard, which has gained the certification of Thatcham, the Motor Insurance Repair Research Centre. They also come with an industry-leading full three year warranty.

Kubota (UK) Ltd – Construction Equipment sales and marketing manager, Richard Harrison, said: “It’s not just the new black livery that is making the new Kubota Dash 4s distinctive, it’s the host of modifications, improved technology and the extra power that we have given them that really makes them stand out from the crowd.

“We are pleased that all the companies in question are thrilled with their new machines and we are getting more excellent feedback every day. The introduction of the first models in our new Dash 4 range is a significant step forward for Kubota, so we are delighted that the innovations we develop in the factory are now providing our customers with significantly increased benefits.”

Kubota is the UK, European and world leader in mini excavators, with 19 models spanning the weight range from 980kg to 8 tonnes, providing the widest choice of machines from a single manufacturer and the largest selection of increasingly popular zero tail swing minis.

The excavators are all known and respected for their quality, performance, versatility, excellent residual values and exceptional dealer support, together with legendary reliability and durability.

Fagerhult Lighting worked with the Royal Holloway University London to provide both a design for the refurbishment of the new Bedford Library and to supply the complete package of luminaries and control.

Fagerhult were approached by ISS Adviance, the building services consultants for the project to fulfil the lighting brief for the library spaces and designed a scheme which provided 350 lux on the library floor, vertical lighting to shelving and lighting for both breakout and meeting spaces. The design integrated Exor Controls with movement sensing and dimming throughout the scheme.

High levels of uniformed lighting were expected at floor level within the library racking and on the books themselves. This was achieved by using Fagerhult Loop Light and the Terazza Louvre 2 x 35 Watt. The selected fitting produces both effective direct and indirect lighting and is installed as a suspended linear run with integrated control sensors. The study areas and open plan multi- media areas are constantly in use and Fagerhult Loop Light was again used in conjunction with low energy downlights installed adjacent to large open windows. The luminaires were linked to movement detectors and also dim the fittings in relationship to increased light levels from natural daylight.

Visual interest was created using recessed Como luminaires and Liverti pendants within the librarians work areas and other break out spaces. Lighting control was also added to these luminaires. “Fagerhult are committed to reducing our environmental impact so incorporating controls is a key factor in our design” says designer Rob Miller. “The detectors automatically assess how much light is in the room and adjust the illuminance levels accordingly, even taking into account the condition of the lamp, ensuring the optimum lighting level is achieved 24/7. As the luminaires are only producing the amount of light required, energy consumption, and therefore bills, are kept to a minimum without compromising the learning environment.”

Building 85 lies within the campus of Southampton University, and is the new home for the Institute of Life Sciences. This new, state of the art building cost in the region of £34 million to construct, and core to the design was the use of sustainable and low maintenance materials, a category which included fire glazing systems from Fendor.

Over 40 different fire glazing elements were required for the interior of the building, ranging from screens, doors and panels offering 30 minutes fire rating in the atrium to 60 minute fire rated doors and screens in the lift lobby. Architects NBBJ of London were responsible for the design and according to project architect, Crysta Falcon, the Fendor Fireline system was the best option in terms of performance, appearance and sustainability.

“We chose the Fireline system because of its proven ability to offer the required fire rating, and due to its fire performance without having to compromise aesthetics in the ten metre atrium, ” she commented. “The whole theme of the building raises the bar in terms of design sustainability, with timber featuring heavily both internally and externally.

The cladding is Western Red Cedar and the internal panelling is bamboo. The door and joinery features are also timber and the steel Fireline system was the ideal complement to the wood detailing. Polyester powder coated finished, the fire glazed elements offer very low maintenance, significantly reducing the need for repainting and redecoration.”

The Fireline range of fire resistant glazing meets all legislative and safety requirements for fire integrity and fire insulation, and offers natural light into buildings whilst still performing its primary function. This enables it to be used as a design medium in its own right, as is the case at Building 85 where the glazing complements the rest of the interior design.

The seven story high Institute of Life Science was opened earlier this year, and students at the university now have a new location for their studies, a building that is modern, contemporary and meets all regulations for fire safety and security.

The feature-packed MEM Memera Consumer Unit range has been redesigned and expanded. It now includes units developed specifically to overcome problems faced by installers endeavouring to meet the requirements of the 17th Edition of the IEE Wiring Regulations (BS 7671), in particular the need for more wiring space when units are fitted with RCBO protection of individual outgoing circuits.

Features of the new range include:-

* A new 11-way unit designed specifically for RCBO protection of outgoing ways
* Moulded and metal enclosures with up to 19 and 38 outgoing ways respectively
* New 1-way and 2/3-way consumer units
* A new 80A + 63A dual-RCD option
* Type B or Type C MCBs and RCBOs
* An option for protective and control devices to be factory-fitted

Electrical contractors have found that conventional consumer units do not allow enough space for wiring when RCBOs are fitted instead of MCBs to protect individual outgoing circuits. The range now includes an 11-way consumer unit designed specifically to take RCBOs and yet allow generous space for wiring above the devices. Individual RCBOs offer the highest possible level of personal protection demanded by BS 7671.

Other advanced features that have long distinguished the Memera 2000AD units are retained. These include the unique snappable busbar that allows on-site configuration of split-load units, a removable pan assembly that simplifies installation, and extremely flexible cut-out provision for cable entry in the rear of the moulded units.

The new units offer DP isolator or RCD incoming main switch options. Versions are available to satisfy the many configurations required to enable an installer to comply with the personal protection requirements of the 17th Edition of the IEE Wiring Regulations.

They include isolator-controlled single and dual RCD units, dual RCD variable split-load boards and the new 11-way RCBO board. In addition to the existing dual RCD split-load arrangement with two 80A RCDs, there is a cost-effective alternative with one 80A RCD and one 63A RCD. At the smaller end of the range are new one-way and 2/3-way units suitable for extensions and additions to existing installations, garages and outbuildings.

The moulded units are available with up to 19 outgoing ways, as with the existing Memera range, to cope with modern requirements for more circuits and/or special control and command devices. If more ways are required, two units can be linked together by means of AD coupling kits. Metal consumer units are available for surface or flush mounting and include dual-rail units offering up to 38 outgoing ways, as well as multiple RCD split-load units and dual/multi tariff arrangements.

The new range of outgoing devices includes single-module miniature circuit-breakers (MCBs) up to 63A and single-module RCBOs (combined MCBs and RCDs) up to 45A. In addition to the standard Type B devices, Type C MCBs and RCBOs are also available for applications involving high inrush currents, such as some lighting loads, which are prone to cause nuisance tripping with some Type B devices. The offering also includes a full range of control and command accessories including timers, relays and contactors.

The new MEM Memera consumer unit range supersedes the Memera 2000 and 2000AD ranges. Devices will continue to be available to fit these units for the foreseeable future.
