High Rise

High, Quality solutions

For offices and residential, hotels and lower level entertainment complexes, ASL's distributed PAVA systems are ideal. Our systems not only enable sophisticated emergency and evacuation scenarios, but help run and manage your building day-to-day.

High rise buildings have specific and demanding requirements for the management of emergencies, ranging from controlled evacuation in the event of fires, to a safe response to security threats such as terrorist acts and bomb scares.
The high quality audio delivered by ASL’s distributed Public Address and Voice Alarm (PAVA) systems help you run your building, while meeting the highest standards of voice alarm and safety communications, and enabling efficient installation and system maintenance.

Phased Evacuation

In high-rise buildings traditional alarms such as fire bells can cause confusion, congested escape routes, and prolonged evacuation times. ASL PAVA systems can save lives by managing phased evacuations. Different voice alarm messages are played into different areas, so that just a few storeys or areas of the building are evacuated at a time, directing the occupants to safety via a planned exit route.

Individual zones or areas of the building can also be manually addressed by emergency services, to help keep people calm, and to enable an orderly, safe,and rapid  evacuation.

High Efficiency

ASL’s novel power amplifier and power supply design combines the excellent audio performance expected from a professional audio system with the high efficiency and low quiescent consumption needed for a battery-backed Life Safety System. ASL’s multichannel amplifiers can also be configured to provide the exact power requirement to each zone, with no waste.

Very low power consumption and heat output, enables an extremely competitive cost of ownership.

Scalable and Flexible

ASL’s PAVA solutions cater for expansive public spaces with ease, using built-in fibre-optic IP networking or Dante connectivity, for fast and reliable audio distribution across many floors, and between buildings.

ASL’s redundant network and equipment technology safeguards the system’s operation even in the event of a system damage or widespread disruption.

As commercial sites are constantly changing environments, ASL systems are designed with full flexibility in mind, offering easy expansion options to accommodate newly created spaces.

Multilingual Support

ASL’s iVENCS Control System provides intelligent artificial messaging for hotels. The iVENCS GUI can be translated into different languages, and announcements can be stored and played in multiple languages, including text to speech.

ASL’s microphone user interface is also available in a number of languages, and new languages can be added as required.

Challenging Acoustics and Noisy Enviroments

ASL’s powerful DSP Digital Signal Processing provides sophisticated EQ Equalisation Controls, while DANS Dynamic Ambient Noise Sensors and continuous noise compensation technology enables broadcast intelligibility to be optimised to cater for varying real-time ambient noise levels.

Entertainment and Safety

ASL’s professional audio PAVA systems provide high quality background music, to ensure a relaxing and consistent customer experience, as well as providing the highest standards of safety.

Local control of music source and volume allows tenanted areas to create their own ambience. without the need for a separate system, and without loss of control to the site staff.

Networking and Audio Distribution

High-rise buildings often have equipment nodes spaced widely apart on different towers and floors. ASL’s IP networking capability allows equipment installed in remote locations to operate together as a single system, using dedicated failure-resistant redundant copper or fibre IP networking.

Easy Migration to ASL

ASL understands that PA migration come with risks and often happen in stages. ASL systems can readily work with existing third-party PA systems either during a changeover phase or on a permanent basis to manage risk in a predictable way.

Cyber Security

To secure the PAVA system and to ensure uninterrupted operation: ASL’s solution supports full encryption and authentication of control and audio data, including 2Factor authentication for tools and configuration management.

Single Box Wall Mount PAVA

Lower installation costs and a considerably smaller footprint than a typical 19″ rack makes ASL’s powerful but compact wall-mount INTEGRA PAVA system ideal for high-rise buildings, where installation space is at a premium. Typically, an INTEGRA is located in the service core, on every other floor or on every few floors, depending on the power requirements and zone count on each floor.

The INTEGRA is based on the same powerful DSP router as ASL’s rack mount systems, and can be fitted with amplifiers for up to ten PAVA zones with a maximum total power of 2000W RMS, so small size doesn’t’ mean low feature or low power. 

PA Wall Controller

ASL’s WMC01 Wall Mount PA Controller is used to choose from a list of audio sources and to adjust their broadcast volume levels.

The controller is typically installed in restaurants, meeting rooms and hotel lobbies, to allow users to select from a list of different music channels and to adjust the volume.

Building Management

ASL’s PAVA systems can be combined with ASL’s award-winning iVENCS Control System for comprehensive building management. The iVENCS control system is normally run from dual-redundant servers, and allows users at multiple workstations to monitor and control a multitude of subsystems around the building, including fire detection and safety systems, CCTV, access control, intruder detection, information and advertising displays, telecoms, network monitoring and more.


The iVENCS Control Software is a truly open and intuitive integrated management platform

iVENCS - Integrated Site Control

ASL’s enhanced iVENCS Site Management System provides integrated distributed control

The iVENCS Control System has recently received an entire technology and GUI upgrade, consolidating its place at the forefront of the management of the public in large sites.

iVENCS is a truly open and intuitive integrated management platform which offers robust control, monitoring and incident analysis across all safety, security and communications subsystems. Plus, in addition to the standard subsystems and functions, iVENCS provides the flexibility needed to provide custom integrations with industry-specific  and site-specific equipment.

iVENCS provides the ability to integrate and simplify the control of all aspects of site management, with powerful and simple to use telecoms and security controls. System control and monitoring can be provided at a central control room and at distributed workstations, all running from multiple redundant servers. Customised staff information screens and site overview video walls can be provided, which combine alarm and status reporting with CCTV views.

The award-winning and unique true 3D GUI can show an accurate, fully scaled model of the whole site. The model’s pan, tilt, rotate and zoom controls allow the user to move the viewpoint at will, to any part of the 3D model and to any floor or groups of floors, with seamless viewing from any position. his avoids other system’s need to split the building GUI into multiple small 2D maps and false-3D building plans, requiring the operators to switch between many different maps in order to operate the building’s equipment.


Key Features:

  • Award-winning 3D or traditional 2D GUI
  • System schematics and dedicated subsystem controls
  • Consistent and simple to use functionality, for multiple systems
  • Industry and custom site-specific integrations
