From the iconic “Mind the gap” echoing through Underground tunnels to the clear, reassuring announcements guiding passengers across railways and stations - our technology has become part of the city’s rhythm.
Today, our trusted communication systems continue to power safety and efficiency in London’s most vital spaces: transport networks, exhibition centers, commercial buildings, and smart public areas. These stories below are just some of the stories that Zenitel and London share.
Where in London Can You Find Zenitel Solutions?
London Bridge Station
Zenitel implemented a new ASL PAVA system spanning 45 zones with 10 cabinets across two communication rooms at London Bridge Station, ensuring long-term reliability and compliance with EN 54 fire‑alarm standards. This upgrade modernised the station’s public address infrastructure with minimal downtime.
