Zenitel - Customer Success Stories in London
Keeping a City Informed, Connected, and Secure
For more than 30 years, Zenitel has been the voice of safety across London.
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.
Docklands Light Railway
At St Pancras International, Zenitel deployed a robust railways public address system to support London Continental Railways (LCR) and Union Railways North (UCN), handling daily passenger volumes in a major European transport hub.
St. Pancras International Rail Terminal
Zenitel installed a Long‑Line Public Address solution across the DLR networ, including Lewisham, Tower Gateway, Bank, London City Airport, and Canary Whar, using distributed architecture to deliver synchronized announcements system‑wide.
Crossrail Elizabeth Line
Zenitel delivered VIPA public address technology across the full 118 km of the Elizabeth Line, integrating station PAVA systems with the line’s central control for seamless IP‑based communication. This large‑scale deployment supports efficient passenger information delivery across London’s newest high-capacity transit route
Gatwick Airport
Zenitel implemented an innovative, multi‑node IP‑based PAVA and voice-alarm system in Gatwick’s South Terminal, enabling synchronized gate announcements, background music, emergency alerts, and third-party system monitoring.
London Underground
Zenitel’s advanced Public Address and Voice Alarm and Long Line PA technology helps to make journeys on the London Underground safer and more secure.
Jubilee Line
Zenitel strengthened London Underground’s Jubilee Line system by delivering outstanding sound quality across the transportation network via a new Public Address and Voice Alarm system.
5 Reasons London Keeps Choosing Zenitel
Zenitel works closely with architects and engineering consultants to ensure audio solutions are properly designed, integrated, and specified, from acoustic planning to deployment.
For more than 30 years, Zenitel has stood beside London’s transport operators, integrators, and installers. The reason London stays with us is simple: we don’t disappear after installation.
We stay through upgrades, design changes, standards shifts, and daily operations. That continuity gives customers the confidence that every message will be delivered clearly, today and decades from now.
London is a mix of legacy systems, heritage sites, and modern infrastructure. Downtime isn’t tolerated, and maintenance windows are short.
Integrators choose Zenitel because our devices fit into existing environments easily, are straightforward to maintain, and save time across the system’s lifecycle. End-users choose us because controls are intuitive, and the audio clarity is impossible to miss, even in 120 dB peak conditions like King’s Cross.
London’s transport spaces are acoustically complex, noisy, and constantly evolving. Our PAVA solutions manage zoning, reflections, background noise, and sudden shifts in the noise floor — all while meeting strict cybersecurity requirements.
With powerful DSP, automatic volume control, long-life components, and proven scalability, customers know their life-safety system will stay reliable as the city grows around it.
London is loud, crowded, and unpredictable. Clear audio is what keeps people safe and moving. Our approach to intelligibility blends mechanical design, software engineering, and hardware precision.
With intelligent noise cancellation, automatic volume adjustment, full-duplex audio, and IP-based integration, Zenitel delivers clarity on the first try. No repeats. No confusion. Just messages that get through in every environment.
No transport site in London runs on a single technology. It’s audio + CCTV + access control + passenger information + building systems, all of it tied together by the integrator.
Zenitel is chosen because we work closely with integrators from design to commissioning, ensuring every device and system communicates as one. When collaboration starts early, the result stands up to London’s pressure, passenger volumes, and maintenance demands.
As PAVA systems become more integrated and remotely accessible, they also become potential entry points for cyberattacks. That’s why cybersecurity isn’t an afterthought at Zenitel, it’s embedded into the core of our solutions.
Zenitel PAVA systems are designed with a “defence-in-depth” approach, meaning multiple layers of security are implemented to reduce risk, prevent breaches, and ensure system continuity.
From encrypted network communication to strict access controls and auditing features, every component is engineered to help prevent unauthorized access and manipulation.
Communication needs are constantly evolving as your facility changes. Perhaps one of your existing zone power requirements has changed, you need to add more zones to your existing site, or you are adding a new campus, you should be able to scale up your communication infrastructure without a complete overhaul. That’s why Zenitel’s Public Address and Voice Alarm (PAVA) solutions are designed with flexible scalability options at their core.
Our solution gives you the flexibility to combine centralised and decentralised architectures and rackmount or wall-mount installation, dynamic configuration options for zone count and output power and more.
From a single PA controller covering a local area to multi-cluster controllers covering a large-scale multi-site deployment with unlimited power output possibilities, our PAVA makes the system upgrades smoother.
We add an extra layer of scalability with our extensive unified communication portfolio that enable you to meet all your communication needs, including IP public address, voice alarm, and intercoms within one unified platform.
