What is Crossrail and the link with Cygnus?
Crossrail is the Limited company that was set up in 2001 to construct the new railway which will be identified as the Elizabeth line when it unlocks its doors in 2018 to central London. The new Elizabeth line service will also replace Heathrow connect trains however Heathrow Express will continue to provide non-stop service between Heathrow and Paddington. As of December 2019, Elizabeth line trains will run from the airport through the new tunnels, providing a direct link to central London destinations including Bond Street, Liverpool Street and Canary Wharf.
The Cygnus wireless fire alarm system was specified to be installed on some 7 Crossrail projects in London for various uses including bespoke solutions such as emergency exit signal systems mostly operating underground, which due to its advanced technology, the system works just as effectively under as it does over-ground.
The following sites are where Cygnus alarms are currently operating, some of which are stations and some access or ventilation shafts;
Paddington station is experiencing the most substantial makeover since the completion of the original build in 1853. A hyperactive terminal for local, regional and international passengers, the opening of the new station in December 2018 will increase capabilities at this major intersection.
There are 10 Cygnus units incorporated within this job along with a Cygnus control panel. There is also a Cygnus Interface unit which connects the Cygnus units to 19 radio-link heat detectors.

Tottenham Court Road
Located within the heart of West End, The Tottenham Court Road Station is undergoing a significant renovation. The Crossrail project is providing a new underground station and ticket hall at Dean Street (Soho) and a second integrated ticket hall below St Giles Circus on Oxford Street. When complete, Tottenham Court Road will be one of London’s busiest stations, offering an interchange between the Northern, Central and Elizabeth line services with more than 200,000 passengers passing through the station every day.
Over 80 Cygnus fire call point and first aid alarms are installed on this project which are linked to 2 main Cygnus control panels. There are also 4 Cygnus input/output which connects 4 bespoke safety signal lights with the Cygnus alarm units. In the event of an evacuation the light signal stays green to indicate the exit is safe to use, if not, it turns red. Due to the fact that mobile phones are not allowed on site, a paging system is also connected to the Cygnus control panel; when an alert is raised the pager system panel sends a text message to a hand-held pager device that is worn by site managers or first aiders.

Liverpool Street is surrounded by an ever-progressing dense urban landscape and makes the most of the small area available to construct a vast piece of infrastructure. A numeral amount of physical constrictions made this project the most complex to interweave with the existing urban fabric, including existing tube lines, post office railway not to mention a maze of sewers!
Approximately 30 Cygnus units are installed on the Liverpool Street project including a Cygnus control panel and 29 Cygnus Fire Call Point and First Aid Alarms.

Whitechapel / Moorgate
The Whitechapel station is located in cultural and diverse area which is an important interchange between the Hammersmith & City and District lines and the London Overground. The new design approach will reveal the New Elizabeth line weave between these existing transport services to an elevated station concourse which acts as a bridge above existing lines which includes the new ticket hall for all services. Over 25 Cygnus Fire Alarm Call Point units are installed on this project which are linked to a Cygnus control panel.
