Beyond PAVA: Zenitel’s Complete Intercom Solutions for Rail and Transport Networks

Whether in busy stations, trackside locations, or onboard trains, Zenitel’s comprehensive range of intercom systems is designed for high performance, durability ensuring reliable and efficient communication at all times. Built-in noise cancellation and automatic volume control deliver exceptional audio clarity, even in loud environments with passing trains. The audio quality is so clear, it truly has to be heard to be believed.

Zenitel intercoms are engineered for demanding environments, offering robust performance where reliability is critical. The range includes models with IK ratings for impact resistance and IP66 ratings for protection against dust and water ingress. Their durable construction makes them ideal for outdoor and trackside installations.

For high-risk or exposed areas, Zenitel offers Vandal Resistant IP Intercom Stations such as the VR3G-1 and TCIS-2 designed with reinforced steel front plates. With IK10 ratings, these units provide maximum protection against vandalism and physical abuse.

The ECP-C1 Emergency Call Point intercom exemplifies both reliability and smart functionality, developed in close collaboration with a leading transport authority. Designed for critical communication, it features Zenitel’s advanced audio processing technology and enables direct calls to a designated Emergency Response Centre via a single red call button. To support accessibility, the unit includes a built-in Audio Frequency Induction Loop (AFIL) for users with hearing aids. It is fully compatible with the Zenitel Connect-Pro intercom management solution, and integration is straightforward requiring only one external connection thanks to its Power over Ethernet (PoE) capability.

Zenitel also offers a wide range of modular intercom kits, so integrators can find an option that works perfectly in any given space. IP kits such as the TKIS-2 IP Audio kit and TKIV+ IP Video kit utilise the latest technology to create unparalleled HD audio and video quality, along with Open Duplex, Active Noise Cancellation, Automatic Volume Adjustment, and a 10W Class D amplifier.

Many of Zenitel’s intercoms and kits, comply with the EN 50121-4 standard for Railway Applications, specifically addressing EMC emissions and immunity of signalling and telecommunications equipment. This rigorous standard ensures that the devices neither cause electromagnetic interference with other critical systems nor suffer performance degradation due to the electromagnetic disturbances typical in rail environments. Compliance with EN 50121-4 is essential for maintaining safety and reliability across railway networks, where critical communication and system integrity are paramount. By meeting these stringent requirements, Zenitel’s solutions provide operators with confidence that their communication infrastructure will perform consistently, even in the most challenging electromagnetic conditions.

All Zenitel intercom systems are IP-based and operate using secure SIP protocols, ensuring easy integration into existing transport networks while delivering superior audio quality.

A wide range of customization options are also available. These include tailored finishes, localised text, and built-in induction loops to meet accessibility standards and adapt to specific regional requirements. For environments where aesthetics are a priority, certain intercom kits can even be installed discreetly behind custom, customer-facing panels, maintaining the visual integrity of station designs.

Zenitel is committed to delivering exceptional reliability and lasting value to its customers. By integrating PAVA, intercom, help points, and access control into a single unified critical communication platform, Zenitel enables streamlined deployment, simplified maintenance, and improved system-wide situational awareness.

"At Zenitel, we understand that no two transport environments are the same. That’s why we offer a highly customisable range of communication solutions—from station platforms and help points to trackside and rolling stock,” explains Henry Rawlins, VP Product Management at Zenitel. “With our extensive product portfolio and ability to tailor everything from appearance to functionality, we provide the right fit for every application — without compromising on performance or reliability."
