The Zenitel Advantage
Backed by advanced audio engineering, patented amplifier innovation, deeper understanding of customers and a strong global partner network, we help organizations create safer, smarter, and more connected environments through Unified Critical Communication.
Sri Sutharsan, VP Onshore Marketing
Our PAVA portfolio is designed to support a wide range of applications, from voice evacuation and emergency communications to operational announcements, security messaging, and background music. That means we can support everything from transportations and industrial facilities to commercial buildings, campuses, and public venues.
Hanne Eriksen, SVP Transporation Solutions
Our customers know what to expect from us. We’ve built a PAVA portfolio that covers a wide range of needs — from smaller installations to large, complex, multi-site deployments. And importantly, we’ve done that with a strong focus on reliability, long-term performance, and backward compatibility.
Thomas Hægh, Chief Technology Officier
Zenitel has always been at the forefront of meaningful technology innovation in critical communication. With the introduction of the VAIA product line, we set out to rethink the amplifier from the ground up.
At the core of VAIA is a newly patented amplifier architecture that delivers transformer-like output performance — without the need for traditional bulky output transformers. This fundamentally changes both amplifier performance and system design.
Antti Karjalainen, Managing Director, Zenitel Finland Onshore
As a technology partner, we go beyond traditional product support. We actively guide our customers on system design, integration possibilities, and increasingly important areas like cybersecurity.
With VAIA, we have a valuable addition to our PAVA family that provides performance and resilience in an efficient footprint. This streamlined approach helps ACEs deliver solutions that are not only compliant and high-performing, but also significantly more cost-effective over the full lifecycle.
Peter McKeag, Onshore Safety & Security Product Manager
VAIA is a great example on how customer needs can drive innovation. The result is an EN-54 compliant system with a smaller form factor that sacrifices nothing in terms of power and voice clarity that people have come to expect of Zenitel.
In addition, it was important to combine the systems robustness and reliability with better usability: Simple installation and faster maintenance make it is a true out-of-the-box system that will reduce both downtime and frustration.
Rahul Ramachandran, Onshore Techno-Solutions Manager
Certain environments present significant communication challenges. Hospitals, for example, consist of corridors, wards, operating rooms, reception areas, and waiting spaces — each with very different acoustic characteristics. Yet across all of these environments, it remains critical that messages are clearly heard and easily understood.
This is where VAIA makes a difference. Designed to deliver exceptional speech intelligibility and audio clarity, VAIA ensures that important announcements and critical messages are communicated clearly, reliably, and consistently — when it matters most.
Frequently asked questions about the Public Address and Voice Alarm system
A Public Address (PA) system is designed for routine communication such as announcements, security alerts, and background music in public spaces. A Voice Alarm (VA) system is a regulated life safety system used for emergency communication and evacuation, typically integrated with fire detection systems and compliant with standards such as EN54. For more details, check out our blog post on the PA and VA difference.
As Voice Alarm (VA) systems are used for life safety and emergency communication, building owners must ensure that all fire safety components — including VA systems, smoke detectors, and fire control panels — operate reliably and efficiently to support safe and effective evacuation during emergencies.
Within EU member states, EN54 is the mandatory European standard governing the design, testing, performance, and installation of fire detection and fire alarm systems.
A well-balanced PAVA system provides compliance with all local, national, and regional certification requirements for emergency use, while maintaining the high acoustic performance demanded by background music, operational, and security announcements. For more details, check out our blogpost tackling the importance of PAVA.
A 100V PA system distributes audio from centralized amplifiers to multiple loudspeakers over speaker cables. It is valued for its scalability, long cable-distance capability, cost-efficient speaker distribution, and suitability for EN54-certified life safety applications.
An IP speaker-based PA system distributes digital audio over a standard IP network. Each speaker includes a built-in amplifier and network interface, making it ideal for flexible zoning, individual speaker control and monitoring.
Many modern PA installations combine both technologies, using 100V systems for large-scale audio distribution and IP speakers in smaller or critical areas requiring advanced zone control and monitoring. For more details, check out our blogpost on scalable PAVA solutions.
A Voice Alarm (VA) system is part of a fire detection and emergency communication system that uses live or pre-recorded spoken messages instead of — or alongside — traditional alarm tones or bells to assist occupants during a fire or emergency situation.
The system informs people about the emergency and provides clear evacuation instructions based on the building’s evacuation strategy. In smaller buildings, this may involve simultaneous evacuation of all occupants, while in larger multi-storey buildings, the system may instruct occupants to evacuate specific areas, remain in place, or await further instructions, also known as phased evacuation.
