The European Voice Alarm Systems market is growing, driven by legislation and building regulations mandating the use of voice alarm systems in certain categories of buildings. The EN 54 standards that have been enforced since April 2011 are expected to affect market dynamics due to the cost of certification and compliance testing. Centralised voice alarm systems dominate the market but those based on distributed architecture are slowly gaining market share, especially in large projects with complex layouts. Western European countries are expected to lead growth through the forecast period, with the exception of Spain and Italy.
