Nuclear

Safe and secure with ASL

Delivering successful Public Address and Voice Alarm installations to both nuclear and fossil fuelled power stations, ASL has established itself as an industry leader.

Providing unprecedented reliability, ASL solutions conform to the most exacting requirements for the most critical of sites. Our reliable networked PAVA solutions deliver clear safety and operational announcements across the site, with redundancy built-in as standard.

ASL offer a wide range of proven products and solutions for high-security infrastructure, offering supreme levels of reliability in an application where there is no room for compromise on safety.

  • Security and operational staff can inform
  • Fire and emergency staff can protect

Environmental Factors

As a key safety system at critical infrastructure sites, ASL equipment offers the highest availability and a robust architecture, with an option for full active A/B redundancy, whilst remaining unaffected by environmental and electromagnetic factors as defined by the safety standards BS EN 61000-6-4 and BS EN 61000-6-2.

 

Minimised Downtime

ASL’s decentralized architecture, built-in redundancy and automatic hot standby systems provide high availability. However, if something does go wrong, ASL’s modular hot-swap amplifier cards even allow maintenance while the system is live, while ASL’s ‘hardware bypass’ function enables local emergency microphones to operate even if the router’s CPU and DSP processing have failed.

Peace of Mind

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. Long, reliable, product life also means lower ownership costs and low whole life costs.

Challenges

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.

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.

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.

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.

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.

Custom Consoles

ASL’s ability to consult, design and manufacture custom consoles for the nuclear industry means that customers get exactly what they need, without compromise.

A wide range of call stations are already available in EX and non-EX types. The Exi, Exm and Non-Ex call stations can either connect to the PAVA 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 ASL’s oil and gas industry partner as part of ASL’s PAGA range.

Specialist Speakers

To overcome challenging acoustics and typically noisy environments ASL has a large range of specialist speakers designed to meet the most stringent conditions.

The loudspeakers’ high sensitivity provides increased announcement volume for each Watt of audio power, and makes them especially suitable for large expansive halls and spaces.

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 low distortion – with the high efficiency and low quiescent consumption needed for a battery-backed Life Safety System.

The amplifiers’ large power output makes them ideal for expansive halls and large spaces, while low power usage reduces lifetime energy usage, and reduces equipment room cooling requirements.

iVENCS

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

iVENCS - Integrated Telecoms 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 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.

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 building 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.
