The installation by Chelsford-based MPE Alarms is part of a GB pound 4.5m refurbishment programme by the City of London Corporation.
The 18-month programme at the popular visitor attraction will involve the cleaning and repair of stonework and the re-gilding of its famous golden orb as well as installing the fire detection technology.
The restoration work has been carried out by Cathedral Works Organisation (Chichester) Ltd.
EMS Group’s 5000 FirePoint system was chosen because “it completely eliminates expensive fire-rated cable and the potentially damaging installation works often associated with wired systems,” says the company.
Sir Christopher Wren’s flame-topped Monument to the Great Fire of 1666 is the tallest isolated stone column in the world with 311 spiral steps to the top.
To install fire-rated cable in this historically important building would not only have been prohibitively expensive, but also damaging to the building’s interior aesthetics.
The system consists of a main fire panel, combined fire sensor/sounder units and call points. 5000 FirePoint fire sensors are based on established industry designs, have no external aerials and have built-in replaceable power packs with up to a five year life.
“The EMS solution ensures that The Monument will be protected by the very latest fire detection system without the 100,000-plus visitors that climb the steps each year seeing any wiring,” says the company.
The company’s range of radio-based systems include analogue fire detection, voice evacuation, intruder security and personal protection.
