ASL's PAGA Platform

Where safety is paramount, ASL PAGA solutions provide security, reliability and peace of mind. Our equipment is certified for these specialist environments, so you can be confident that ASL has the right solution for your next onshore or offshore project.

ASL systems provide Public Address and General Alarm PAGA solutions for complex infrastructures in harsh environments, such as oil and gas facilities, and wind farms. ASL offer a wide range of proven products and solutions, and can provide high networking redundancy and custom PAGA control panels to meet a project’s exact requirements.

ASL’s TMS control systems can monitor and report on equipment everywhere in the installation, can provide staff  information displays, and can even report on a platform’s equipment status in an onshore control centre hundreds of miles away. ASL products offer supreme levels of reliability in applications where there is no room for compromise on safety.

  • Operational staff can control
  • Fire and emergency staff can protect

A/B Architecture

In addition to the high reliability levels provided by ASL’s ‘standard’ products and their designed in redundancy, ASL’s full A/B PAGA architecture provides full audio router, amplifier frame, and amplifier redundancy. This fully duplicated A/B system architecture uses pairs of independent audio routers and amplifier frames which are configured identically, and which are both active at all times.

Remote Monitoring

ASL’s PAGA solution provides full remote 24/7 supervision of both software and hardware. By automating critical background checks ASL also provide an early warning of possible problems, so you can deal with impending issues and keep everything running smoothly.

IEC-60945 Certification

ASL understands the design elements that must all be taken into account to produce products that meet the IEC-60945 requirement. Full certification of our Oil and Gas, and wind farm, solutions has been carried out by our key industry partner.

Protecting Employees and Assets

With more than 25 years experience of designing and developing Public Address and Voice Alarm products for critical infrastructure applications, ASL offers peace of mind. You can rely on ASL solutions to work, and to continue working, throughout the life of the system.

Our PAVA systems will deliver the message to where it needs to be heard, when it needs to be heard.

High-Security Infrastructure with Limited Access

Remote monitoring and configuration makes the operation and maintenance of ASL PAVA systems easy, even for equipment installed in the most sensitive and hard-to-reach areas.

Challenging Acoustics and Noisy Environments

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.

Low Operational Costs

Proven reliability: With ASL’s first generation systems still installed and running. Long, reliable, product life means lower ownership costs and low whole life costs.

Efficient power supplies and amplifiers reduces lifetime energy usage, and reduces equipment room cooling requirements.

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.

Sector-Specific Products

ASL combines close liaison with our customers and end users, technological innovation, and the comprehensive knowledge of our experienced team to tailor our products to industry-specific requirements, and to set new standards with our dedicated industry specific products. A few key examples are referenced below.

48V Power Supply

ASL’s V2000 supports a 48V battery backup power supply. This feature has been included in the product specifically because this power supply is common in the petrochemical industry.

High Output & Low Power

ASL’s D500 500W amplifier card uses a novel design which combines the excellent audio performance of a professional audio system – such as low noise and distortion – with the high efficiency and low quiescent consumption needed for a 48V battery backed PAGA System.

ATEX Microphones

A wide range of call stations are available in EX and non-EX types.

The Exi, Exm and Non-Ex call stations can either connect to the PAGA IP Router via direct dual-redundant cables with analogue audio and RS-485 control, or can connect over the IP network.

These microphones are available through our industry partner as part of ASL’s oil and gas PAGA range.

iVENCS TMS Telecom Monitoring System

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 large installations, and is already installed to monitor over thirty systems at a large offshore petrochemical complex.

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.

The award-winning and unique true 3D GUI can show an accurate, fully scaled model of the whole complex. 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 building, platform, or floor, with seamless viewing from any position. This avoids other system’s need to split the 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 site’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
  • Remote Condition Monitoring
  • Distributed processing with multi-site redundancy
  • Modular system architecture; easily expandable
  • Cross-platform support
  • No ongoing license costs

Site operators need to monitor an ever-increasing number of subsystems, from fire detection to CCTV, PA to information displays, access control to intruder detection, and far more. ASL’s award-winning iVENCS Control System empowers both managers and operators to simultaneously control a multitude of systems. Via the intuitive 3D user interface, staff can keep a constant eye on the status of equipment around the site, are able to remotely control devices, and be alerted to any faults and devices that are in need of investigation.

iVENCS makes staff communications easier to manage, through auto-scheduled announcements, intelligent message builders and information displays.
