It enables both live emergency voice announcements and the activation of pre-recorded messages, ensuring flexibility in emergency communication scenarios. Featuring a high-quality cardioid electret microphone, the unit provides clear and intelligible voice transmission. Designed to comply fully with the EN 54-16:2008 standard, the BM 3804 includes a complete self-diagnostic function and system status indicators to enhance reliability and safety. Up to four consoles can be daisy-chained together using J-Type fire-rated cabling.
