RH Consulting have launched a major new edition to their guide to voice alarm systems. Originally released six years ago this publication has been comprehensively updated to become the definitive guide to all types of emergency audio system aimed at consultants. manufacturers, installers and venue owners.

The book runs to about 200 pages and is packed with tables, diagrams and animations to help people understand this often misunderstood subject. The guide covers standards worldwide, including Europe, Australia and the USA. It also gives comprehensive information on the industry-changing topic of EN54.

‘We wrote the book on two levels’ says Roland Hemming. 'For those new to the subject it gives a comprehensive overview on how voice alarm systems work and how to understand the different standards. For the experienced practitioner it has detailed information and tables to allow people to cross-reference what different standards say on each issue.’

One of the great features of the book is an interactive guide to help you work out what standards to use for voice alarm projects across the world - a simple decision tree takes you through the steps to find the correct standards.

‘This is the first time that such a task has been carried out’ adds Richard Northwood ‘Rather than embroil the reader in the usual confusion over which standard to use, we have clarified and explained why you should use a standard on a project.’

There are over 100 graphical examples to assist those who don’t have English as their first language.

The book is available worldwide on the iTunes book store for iPhone, iPad and Mac.

To buy a print version companies requiring an invoice can order directly from us, alternatively it's available on amazon.

by Sam De Pauw - Feb 15, 2016

"Finally a comprehensive, yet very easy to read, reference book that demystifies standards and practices in PA and Evac systems used worldwide! Even though the current EN54 standards are currently under revision, this guide is a must have for anyone who’s manufacturing, planning or integrating Evac or PA systems for the next years to come. Thank you."

by Neil Voce

"If you have any active role in VA, this book is almost certainly going to tell you something you didn't know. It's a valuable addition to your library, and, if you're involved in the voice alarm business internationally. the comprehensive tables on standards requirements alone justify the investment of the time and money."
