WES+Northern Line Extension Project, London
Contractor: Laing O’Rourke (FLO) / Ferrovial Agroman
Project Type: Development
The Ferrovial Agroman and Laing O’Rourke (FLO) Joint Venture has selected the WES+ wireless re alarm system for its above ground, temporary site accommodation and Battersea shaft site, on the much-anticipated Transport for London, Northern Line Extension project.
WES+ was chosen because it is a wireless fire alarm system that complies with all relevant sections of EN 54.
The 9th edition of The Joint Code of Practice (JCoP) reinforces the need for construction site fire alarm systems, including temporary accommodation units, to meet this important standard.
Version 9 of JCoP states the following: Components of automatic re-detection and alarm systems should be marked as complying with EN 54 (paragraph 13.8). JCoP is produced by the FPA (Fire Protection Association), and used by the insurance industry, simpli ng the specification of construction site re alarms by clarifying that the system should meet EN 54.
The site team at FLO took a lead from JCoP, which also states that temporary buildings or temporary accommodation located: inside the building under construction, inside another permanent building, or within 10m of such building(s), must be fitted with re-detection systems complying with a recognised category of installation as set out in BS 5839-1: Fire detection and alarm systems for buildings.
This means that components of automatic re-detection and alarm systems used in Temporary Accommodation Units on construction sites should be marked as complying with EN 54.
WES+, being the only wireless fire alarm system developed for construction that has been independently tested and approved to comply with all relevant sections of EN54 was, therefore, the system of choice for the FLO team.
In specifying WES+ for the Northern Line Extension development, the project team at FLO has demonstrated that it places the safety of its personnel, occupants of nearby buildings and its client’s assets above all else.
Billy Killian, Logistics Manager at FLO, Northern Line Extension project, explained: “We’d used WES+ systems on part of Crossrail and already had systems installed at the Kennington Shaft, so when it came to upgrading our systems above ground at Nine Elms and Battersea, WES+ was the obvious choice.”
“We also needed a robust and portable system that could be easily tested and added to over time; we currently have 15 WES+ units in use across the Northern Line Extension project, and plan to add at least another 15 units over the coming weeks and months.”
The WES+ fire alarm call points are fixed in the Temporary Accommodation Units in accordance with the site fire plan, creating a completely secure, wireless network. The alarm system can be manually triggered from any call point. 24/7 protection is also provided by the WES+ smoke and heat detectors, which automatically activate the system in the event of a fire.
A WES+ Base Station provides a site-wide alert across all units in the network as soon as a manual call point is pressed, or if fire is detected by the automatic heat or smoke detectors. The WES+ system uses Category 1 receivers (ETSI 300-220-1) throughout, ensuring maximum signal reliability and does not interfere with
life means the units will provide long-term operation before the need for servicing.
Paul Henson, Sales and Marketing Director at Ramtech Electronics, said “With WES+, FLO and its clients know that the complete system – and every unit in the system, including base station, fire call point or smoke and heat detection unit – have been tested to the relevant parts of EN54. Our WES+ re alarm systems has been used on Crossrail for a number of years and we are delighted that it has now been chosen for the Battersea site.”
The Northern Line Extension project is targeted for completion in 2020.
