Running to 200 pages, it covers all applications where VA systems are likely to be installed, from stadia to public buildings to nightclubs, theatres, transport hubs, shopping centres and much more. It is packed with tables, diagrams and animations to help people comprehend this often misunderstood subject. The guide covers standards worldwide, including Europe, Australia and the USA as well as delivering comprehensive information on the industry-changing topic of EN54.
"We wrote the book on two levels' says RH Consulting founder, 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 offers detailed information and tables to allow you to cross-reference what different standards say on each issue."
One of the most useful 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 necessary steps to find the correct standards.
"This is the first time that such a task has been carried out," adds RH Consulting's 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 which standard on which project."
With nearly 100 graphical examples, the topic of emergency audio is even made clear for people who don't have English as their first language.
