Wireless Fire Alarm System Working Underground

More than 80 Cygnus alarm units are incorporated on the Crossrail project at Tottenham Court Road.

This wireless fire alarm system works effectively underground and in areas of dense concrete. The system includes 2 control panels, a pager system and is divided into 7 different zones.

This project is a total refurb of Tottenham Court Road Station which will provide a new underground station and ticket hall at Dean Street, Soho, and a second ticket hall below St Giles on Oxford Street. Tottenham Court Road Station will be one of London’s busiest stations once the project is complete, with more than 200,000 passengers passing through the station every day.

Cygnus alarm units have also been installed on other Crossrail projects such as Bond Street, Liverpool Street and Whitechapel Stations. Cygnus has been specifically designed for use in dense concrete and steel structured buildings, and areas where there are many other radio frequencies in use. Particular attention has been given therefore to achieving an extremely long range connection and distances in excess of 1.5km have been recorded in an open air environment.

Whilst this range is not guaranteed on site due to limiting obstacles, Cygnus site alarms covers impressive distances and huge areas due to a meshing system which allows devices to communicate through one another and not directly to the panel.
