trouble impressing both the head teacher of Ormiston Victory Academy and the Dodd Group’s project team of its specification merits for the academy’s new purpose-built building in Norwich. “It ticked all the boxes and that of our client,” said Alan Hensby of Dodd Group Eastern, electrical and mechanical contractor for the project. “As a trust, Ormiston Victory Academy took an active role in selecting products for the new school building, which included looking at samples.” Teresa Smith, Director of Finance and Operations, Ormiston Victory Academy, was the project manager for the new building and heavily involved in the selection process of the materials used: “Dodd’s provided us with a number of examples of trunking and we were very clear that we needed a product that was robust, tamper- proof and cost effective. “Equally, I wanted the trunking to look part of


the room and work with our décor. Marshall- Tufflex’s Twin165 trunking was selected for all of these reasons and we are delighted with our choice. We are incredibly proud of our new

installed within the new academy building by Electrical Engineering Services, King’s Lynn. The product was supplied by Edmundson


Electrical, Bury St Edmunds. The £11.7 million project was finished three months ahead of schedule. The enlarged school now accommodates 1,250 students. Twin165 is ideal for buildings, such as schools,


building and state-of-the-art facilities,” she said. “Marshall-Tufflex came out best when we


looked at different cable management options and it provided value for money compared with the competition,” added Mr Hensby. “We particularly liked the simplicity of its


design and ease of installation when up against time. Some systems we considered were fragmented and not tamper-proof. Being a tamper-proof, all-in-one unit with double compartments, Twin165 gave us the depth of capacity we required without being over-bearing in width, easily fitting spaces around windows and radiators. It also gave us flexibility for future- proofing without disturbing the fabric of the building. We like nice and easy trunking!” Some 284 lengths of Twin165 in white with grey lids to meet DDA requirements were

fed from essential and non-essential distribution boards, flex7 Dual Supply Starter Units were identified as ideal – answering the need to control two independent circuits with a single switching device. Dual Supply Starter Units are factory configured to suit their particular area of installation. Each one has the required number of outlets shared between the two circuits.

he Discovery Centre at Dundee University opted to install the flex7


Master & Slave Control Packs were plugged


into either side of the Dual Supply Starter Unit and then linked via their network ports with a short plug-in network lead. This allowed a single wall-mounted retractive switch, connected to one of the Control Packs via a plug-in switch drop, for on/off and regulating control of both circuits of luminaires simultaneously whilst operating at Protected Extra Low Voltage. Occupancy controls were also installed in conjunction with Corridor Hold Units, allowing luminaires in circulation areas to be held on while any adjacent room remained occupied, even if the circulation area was vacant. flex7 Corridor Hold Units are self-powered and are linked to other Control Packs via plug-in


network leads. Each unit can accept inputs from up to eight individual areas, however if more inputs are required units can be linked together to accept signals from more areas. In many buildings where energy-saving occupancy and absence sensors are installed, corridor lights can go off when the adjacent rooms and areas are still occupied. It is sometimes desirable – for safety or security reasons – for circulation luminaires to be held on until such time as the whole area has been vacated. The Corridor Hold Unit (fch8/2) provides the simplest of solutions to this problem.

where cable management solutions for complex and large data installations are required to work alongside power delivery. It is a medium-sized trunking with split compartments for power and data supplies with a greater capacity than traditional similar-sized trunking. It eliminates the need for larger trunking. It has a bend radius


of 50mm, with adjustable internal and external bends for improved flexibility. Designed for straightforward installation and re-configuring, Twin165 is aesthetically pleasing with a modern finish.
