The updated “Studio” dimming system from Eaton offers advanced lighting control for both residential and commercial environments, combining the aesthetic and practical features of Eaton’s stylish COPA (Clip-on plate) range of wiring accessories with the proven technical qualities of its successful Studio 3 commercial lighting controls. The system offers compact and versatile single-channel and multi-channel lighting controls with options for pre-programmed ‘scene’ selection and remote infra-red control. A wide range of light sources can be controlled including linear and compact fluorescent, tungsten halogen and LED lighting.

The stylish new COPA control plates are equally at home in residential and commercial settings such as bars, restaurants, hotels, reception areas, conference facilities, showrooms and places of worship. They offer a choice of ten different interchangeable plate styles, with no visible fixings, and suite with the modern COPA range of wiring accessories which includes switches, socket-outlets and communications outlets.

The modular system comprises two elements – the dimmer packs, which are available in single- and four-channel variants for a wide variety of lighting loads, and the control plates including the new COPA variants. These elements are then interconnected by safety extra low voltage (SELV) bus wiring.

The simplest of the new COPA control plates provides manual dimming of a single lighting channel; it also includes a ‘panic’ button, to turn the lights fully ‘On’, and a fully ‘Off’ button. A second unit can control up to four lighting channels and can be pre-programmed to store and recall up to four lighting scenes created over four channels of lighting. As with all Studio 3 control plates it also incorporates fully ‘On’ and fully ‘Off functions. A third plate offers simple scene recall of any of the scenes created on the programmable plate in addition to the standard fully ‘On’ and ‘Off’ capability.

All three plates are available with or without a built-in infra-red sensor for use with a hand-held remote controller, which can provide manual adjustment and scene recall without the need to access the control plate.

Two types of dimmer pack are available – The first type is a universal unit suitable for mains-voltage GLS tungsten and tungsten halogen lamps, GU10 low voltage tungsten halogen lamps and dimmable electronic compact fluorescent lamps, available in one or four channel variants. The second is a ballast interface unit typically for control of fluorescent lighting loads such as linear fluorescent, compact fluorescent, cold cathode or LED lighting, fed through suitable dimmable control gear. These units are also available with single or four channel output for driving 1-10V analogue or DSI control gear.

A typical domestic application for the programmable four-channel controller would be to provide different lighting scenes for reading, watching television, eating etc. as well as remote operation and adjustment. In a restaurant or bar it might be used to provide different lighting scenes for lunch-time, evenings, special functions, cleaning etc. as well as manual operation e.g. all ‘On’ panic or all ‘Off’ at the access points.

Eaton’s COPA system offers a choice of ten different plate finishes for each accessory. The clip-on plates have no visible screw fixings. The finishes include white, matt black, gold, silver, grey and blue metallic finishes, plus stainless steel, satin bronze, polished brass and a highly polished finish. The clip-on plates enable cover plates to be fitted separately from the basic accessory; this can help contractors’ cash flow and reduce the risk of theft or damage to the accessory during interior decoration work.

The established ‘Classic’ Studio 3 controllers for commercial applications are retained in the range. These have white moulded face plates and are all fully compatible with the new COPA plates.

Leading European water treatment specialist Sentinel is offering a first class self-certification option to contractors that have until now, utilised an external water treatment company to undertake that side of their business. The offer to contractors is straightforward – clean and protect the heating systems you work on and self certify that work via Sentinel’s SystemCheck accredited laboratory analysis, for self-certification compliance. This service is proving to be an attractive option for many larger contractors looking to switch to self certification.

Sentinel System Check is a water analysis service which has been designed to provide the contractor, installer or system owner with a rapid service for validation of water quality in a central heating system. It can be used during system commissioning either after initial cleaning and flushing or after treatment with Sentinel X100 inhibitor. It can also be used on existing systems for a health check to ensure the system is working efficiently and to diagnose any potential long-term problems.

System Check is supplied in a returnable plastic box that contains two sample containers, one for the mains supply water and one for the system circulating water. Full instructions are supplied along with a pre-printed Freepost envelope for return of the samples to the laboratory.

Analyses are carried out by an independent, highly qualified laboratory that operates a quality system compliant to ISO 17025 and a full laboratory report is supplied that contains the results of all analyses undertaken, a full interpretation of these results and recommendations for any corrective action. The report can be sent by post or directly by e-mail.

The Sentinel SystemCheck facility offers a comprehensive response to the needs of self certification compliance and is already working well for a number of larger contractors using the service. It offers an affordable, cost effective alternative to employing sub-contract water treatment specialists to undertake the water treatment side of your installations, whilst you incur substantial cost by doing so.

And to help still further, the easily recognised Sentinel X-range of chemical water treatment products has just got bigger – literally. The leading water treatment and energy efficiency expert has just released its X400 heating system restorer, X300 system cleaner for new heating systems and its X200 noise reducer product, along with its X100 inhibitor and system protector, in 10 litre packs for use in light commercial projects.

The new size packs offer installers and contractors working in the light commercial sector the convenience of buying what they need when they need it, reducing visits to the merchants or their stores and making it easier to carry in their vans. And the Sentinel range has been endorsed by a range of leading commercial system manufacturers, keen to see quality water treatment products used in their products to ensure they continue to operate at optimum efficiency levels.

“We’re serious about offering a service second to none to the commercial sector and we believe that this development will allow many commercial contractors that have until now, looked for specialist support in this area to keep that work in-house and utilise the self-certification route to meet the legislative requirements,” says Sentinel’s Commercial Sector Manager, Mark Kelly.

“It’s also been suggested to us by commercial contractors that it would be helpful to have something between the usual 1 litre bottles and the 20 litre packs so we’ve responded by producing these 10 litre versions to widen our product offering,” says Sentinel’s Mark Kelly . “Systems still need to be dosed correctly – one litre for every 100 litres of the system water, and this new size will be particularly helpful when dosing systems in hotels and guest houses, offices and small industrial units and the like.”

MK Electric has recently compiled a collection of wiring accessories ideally suited to the demanding needs of the healthcare sector – whether they be safety, security, and hygiene. The collection encompasses anti-bacterial switches and sockets; lockable and surge-protected devices and accessories dedicated for those with disabilities.

MK Electric’s Logic Plus wiring accessories range has now been demonstrated to possess significant anti-microbial properties. The Logic Plus range is 99.9% lethal to Methicillin-resistant Staphylococcus aureus (MRSA), compared to 86.4% for similar competitive products; 98.9% lethal to Klebsiella Pneumoniae – compared to 95.4% for other non-MK offerings – and is also 99.9% fatal to E-Coli and Salmonella.

The Logic Plus range is produced using Urea Formaldehyde, a high-grade thermoset material; which has similar inherent properties to anti-microbial additives which inhibit the growth of the four infectious diseases identified. In addition, Logic Plus products are also produced scratch-free – thanks to highly-engineered moulding tools – obviating the occurrence of dirt traps in which harmful bacteria may lodge.

The company’s Masterseal, Metalclad Plus, Edge and Albany Plus products are now also all available with key-operated locks to prevent unauthorised tampering of the power supply. The 20A double pole key operated switch and 13A double pole key operated socket feature printed terminal markings and universal lock. The key can be removed from the lock in both the ON or OFF position, so ensuring that power is either maintained or withheld according to need. The universal lock allows one key to operate a number of devices, simplifying the security process.

MK Electric also offers Isolated Power Supply (IPS) sockets that are double pole or un-switched; are ‘Clean Earth’ and are colour-coded blue with engraved white lettering stating ‘Medical Equipment Only’. Where white outlets are preferred; they can should be mounted on a blue background, with the socket engraved ‘Medical Equipment Only’ in blue lettering.

An IPS increases the supply resilience by reducing the impact of first fault conditions downstream of the IPS. The IPS is usually combined with an uninterruptable power supply (UPS) that prevents disruption of the supply owing to problems upstream of the UPS.

Other product’s in MK Electric’s very comprehensive range that lend themselves to healthcare environments include: lighting control sensors for better management of energy consumption; colour-contrasted, large rockered and pull-cord operated switches to assist the less able; and a extensive series of data and power cable management systems.

Backed by MK’s unrivalled quality, reliability and service; the ranges – outlined in the new eight-page MK publication Healthcare Sector Products – are guaranteed for between 10 and an impressive 20 years, depending on product.

"Wilo-Stratos" series extended for commercial buildings

Full functional range also for small performance ranges / Universal high-efficiency pumps for heating as well as for cooling and air-conditioning / Integration into building automation possible

Leading pump and pumping system expert WILO has introduced an extended range  of its new high-efficiency Wilo-Stratos series. The Stratos range has been extended by adding seven further models for connections ranging from DN25 to DN50. The Wilo-Stratos series offers power-saving, high-efficiency pumping with a range of control options and interfaces to building automation systems, but can also be used for smaller performance ranges, up to a delivery head of 4 m. They are ideal for smaller heating and cooling circuits in commercial buildings. This latest range extension allows for easier replacement of old, uncontrolled pumps by new generation, high-efficiency pumps.

Supplied with an IF-Module, all Wilo-Stratos pumps are suitable for integration into building automation systems. Pumps can be made bus-capable in line with today’s standards –  LON, CAN, BACnet or Modbus. In addition, these high-efficiency pumps have an infrared interface for pump monitoring. This interface enables wireless reading of all relevant pump data over several metres distance to the pump, through the use of a Wilo-IR-Monitor remote enquiry device, or a Wilo-IR-Module for pocket PCs. The Wilo-Stratos high-efficiency series offers a power saving potential of 80% compared to uncontrolled pumps and has been the reference standard for Class A energy efficiency heating pumps since 2001.

The pumps can be applied universally. For load adjustment, they can be pre-set to the control modes constant differential pressure (Δp-c), variable differential pressure (Δp-v) and temperature-controlled differential pressure (Δp-T). Due to the wide fluid temperature range from -10°C to +110°C they are not only optimally suitable for heating systems, but also for the use in cooling and air-conditioning. For this purpose, all Wilo-Stratos pumps have a cataphoretic coating as standard. In addition, accumulating condensate can be safely discharged via a drain labyrinth.

The Wilo-ClimaForm cold water insulation shell is available as a recommended accessory for all Wilo-Stratos series high-efficiency pumps. This is made of a flexible elastomer material – AF/Armaflex – which offers high water vapour diffusion resistance and low heat conductivity. The shell system is a precision made, pre-fabricated unit and fits the pump housing very accurately without affecting the function of the condensate drain system. Time-consuming modifications are no longer necessary, and installation takes only a few minutes even in the most complex installations.

MK Electric – the UK’s leading manufacturer of wiring devices and electrical accessories – has launched a unique Fire Alarm Isolator to ensure that systems comply with the requirements of BS 5839: Fire Detection and Fire Alarm Systems for Buildings, Part 1.

The Standard requires double pole isolation of alarm systems, stating: “To facilitate local isolation during maintenance, suitable means should be provided for double pole isolation of the low voltage supply circuit that serves the power supply and control equipment”. The standard also requires the isolator be lockable in the on and off position; meaning a traditionally-switched isolator will not comply.

MK Electric’s lockable isolator provides a robust, durable and ultimately safe solution to the challenges of BS 5839; and is available in the company’s popular Logic Plus, Aspect, Edge and Albany Plus ranges of accessories. Further finishes are available on a bespoke basis from the MK Electric Design Service.
