Fire and fire safety are evocative subjects; the memory of the fatal Kings Cross fire of 1987 still lingers in the industries memory, and public safety is paramount. Train stations have to be secure but also need to be safe and with many people in an enclosed, and often subterranean building, having a fire sprinkler system that is properly tested is obligatory.
London Bridge is a meeting of overground and underground lines and sees almost 56 million passengers per year. A bustling mass of activity over many levels, the current redevelopment started in 2011, and is scheduled to complete in 2018, when it will see major improvements such as new entrances, less waiting and escalators and lifts to every platform, and the end result will be a faster, more pleasant travelling experience. When Network Rail planned the upgrade at their important London Bridge station, they wanted the very best fire safety system possible, and for their sprinkler flow control they turned to Project Fire Products Ltd, and their innovative and fully automated Zonecheck product.
Zonecheck is an efficient, modern sprinkler flow-switch test system, which is already installed throughout major UK transport locations such as St. Pancras Station and Heathrow Airport, ensuring that sprinkler system tests are carried out as required but within a sustainable and economic way. Sprinkler systems are excellent at putting out fires because they douse the whole area and ensure that everything is saturated. That’s great in an emergency but particularly wasteful when under simply being tested. That is where the Zonecheck system comes in, allowing for easy compliance of periodical testing without excessive use of water.
With flow-switches requiring quarterly tests current methods waste substantial amounts of water without there ever actually being a fire but by installing Zonecheck the user can test the system remotely by simply turning a key. No water is discharged to drain saving over 320 litres of water each test, which negates the need for large fire pumps to run in order to refill the system, again saving energy.
Zonecheck is now being built into the Thameslink Programme and will ultimately help protect the entire station concourse, all service spins, and the iconic London Dungeon, adjacent to the station, providing the whole area with both an effective environmentally friendly fire safety solution.
