| Hochiki’s communications solution has multi-purpose structure to provide flexibility and expansion |
When the Extra Motorway Service Area (MSA) Group opened its facility on the M25 at Cobham in September 2012, it marked the culmination of a project that had first been discussed some 19 years earlier.
Planning issues and some local objections to the size and scale of the proposed development meant that filling a 63-mile gap between service areas on this section of the motorway took rather longer than anyone had anticipated.
Now, for the 190,000 or so motorists that use the biggest ring road in the world every day, the new £75m Extra MSA provides a welcome opportunity to refresh and relax. Located roughly midway between Heathrow Airport and Gatwick Airport, it is home to a number of household names including McDonald’s, Starbucks, M&S Simply Food, WH Smith, KFC, Quicksilver and El Mexicana. In addition there is a 75-bedroom Days Inn budget hotel, while Regus hosts a separate lounge facility and business centre, offering a full range of services and meeting rooms.
Andrew Long, chief executive of Extra MSA Group, comments, “We have worked hard to build a rapport with local groups who originally objected to the development. They feared it would be detrimental to their locality but now they have seen the results, many have complimented us on our work here.”
While those wishing to stretch their legs can take a walk around the large lakeside terrace and landscaped grounds, most of the visitors need one thing and one thing only – fuel. Extra MSA Group developed what is now Europe’s biggest petrol station on the Cobham site. With 36 forecourt pumps and six dedicated high-speed heavy goods vehicle (HGV) pumps – totalling 141 nozzles – it can serve around 3,500 vehicles a day.
Worthing based Electrical Services & Projects Ltd (ESP) won the contract to supply the electrical services to the Cobham Extra MSA. With its vast experience of working in petrol service stations, the company has built up an unrivalled understanding of the specific requirements of these types of projects. It was therefore in an ideal position to provide a fully comprehensive service for this location.
ESP’s director, Colin Garwood says, “We needed a fire detection system that could ensure complete safety for the those visiting and working at the service station, while minimising the possibility of unwanted alarms. Having previously worked with Southern Fire Alarms we brought them in to design, supply and commission a system that could fulfil these objectives, while we handled its installation.”
Southern Fire Alarms is one of the south of England’s leading life safety specialists and the company’s systems sales consultant, David Fell, explains, “Based in Bognor Regis, over the last 35 years we have demonstrated the highest levels of technical competency, professional working practices and ethical conduct. We work across a diverse range of sectors and have an excellent reputation for our quality of service.”
Following a comprehensive site survey, a BS 5389 compliant category L1 addressable fire detection system was recommended. An L1 system is designed for the protection of life and deploys automatic detectors throughout all areas of the building – including roof spaces and voids – with the aim of providing the earliest possible warning.
Fell knew instantly which system would be most suitable. Asked to explain the rationale behind his decision, he replies, “We have worked with Hochiki Europe for many years and the quality of their products is second to none. Also, because of the way their systems are designed, we knew we could make significant time and cost savings on the project.”

| Hochiki’s Chamber Technology minimises the differences in flaming and smouldering fires |
The chosen system is based around Hochiki’s Enhanced Systems Protocol which is a robust total communications solution for intelligent fire detection and fully integrated systems. It has a multi-purpose structure that provides the flexibility and expansion to accommodate simple addressable systems, as well as integrated building management and complex life safety systems.
A wide variety of devices were installed including ALG-EN optical smoke sensors that feature Hochiki Europe’s High Performance Chamber Technology, which minimises the differences in sensitivity experienced in flaming and smouldering fires. In addition, HCPE-E call points, YBN-BSB base sounder beacons, ACB-E multi-heat sensors and CHQ-MRC mains relay controllers were used. Remarking on the speed at which the system was configured, Fell comments, “Once the base is installed, fitting the devices is a fast and efficient process – usually taking about 30 seconds. This is considerably quicker than most other products on the market.”
The building contains a large void due to its barrel vault roof design and this had to be covered by the fire detection system. The devices that are sited in this space were pre-programed in advance so that ESP could complete a second fix before the suspended ceiling was put in place. This proved to be a highly useful feature that helped avoid some complex logistical issues and meant that the devices’ performance could not be affected by work being carried out nearby.
Just as importantly, it also helped to reduce the number of site visits. During the construction process the area was made highly secure – all vehicles had to be liveried and only approved personnel were allowed on site. Therefore, gaining access could often be a time consuming process, so being able to limit the amount of times this had to be done proved highly beneficial.
The installation and commissioning process was incredibly smooth, which meant that the project was finished on schedule. Since it opened Southern Fire Alarms has not been called back to the Extra MSA, a fact that reaffirms Fell’s confidence in the reliability of Hochiki Europe’s products. He concludes, “This was a fantastic project to work on and we are delighted to have been able to carry it out using the industry’s leading life safety solutions.”
