Tower Bridge, London

An iconic tourist attraction and a busy crossing of the River Thames, Tower Bridge is used by over 40,000 pedestrians and motorists every day. The central span of 200 feet between the towers are split and raised
around 1000 times a year for river traffic to pass. The bridge also houses the Tower Bridge Exhibition, where visitors can observe the Victorian engine room.

Overview

The old fire alarm system was in very poor condition, with panels and devices discontinued. A flexible new open protocol system was the way forward, allowing for the easy supply of spare parts and competitive future maintenance tendering.

The Solution

Following a rigorous tendering process, Firetecnics Systems Ltd secured the contract to fit the extensive new fire alarm and detection system which comprised five Kentec open protocol panels, two graphics panels and three voice racks. The Apollo field detection equipment used encompassed 100 manual call points, 350 Discovery units, 50 XPander units and 12 beam detectors. These detectors were supported by 120 visual indicators, 50 interfaces and 200 DNH speakers.

The Verdict

Bob Course, Electrical Engineer at the City of London Corporation says:

"The new system is operating well – the graphics interfaces allow users and the Fire Brigade to clearly see where a fire activation has occurred. Firetecnics and Apollo worked closely with the Bridge Engineers and Superintendent to meet their exacting standards successfully. Tower Bridge, its staff and visitors are now better protected. "
