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.

For a taster of the Guide to Voice Alarm Systems we have made the standards tree freely available
here on the website.

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