EN 54-16 covers voice alarm control equipment; EN 54-24 covers loudspeakers. The first is about zoning, priority and fault supervision. The second is about aco https://www.eastvopa.com/news/es-y60so-column-60w.htmlhttps://www.eastvopa.com/news/es-y60so-column-60w.html2026-10-20ProductA 60W model joins the column range.
