The EHV MP3 Voice Annunciator Horn delivers an industry-leading sound output of 110 dB at 1 m, making it ideal for noisy industrial settings. Users can select between two sound profiles—Signal Mode for high-impact alerts or Information Mode for softer messaging. Designed with high vibration resistance, it features three volume levels, terminal block and cable types, and four playback modes for versatile applications. The M1 version supports both NPN and PNP transistor outputs, and an SD card allows easy message and melody updates (up to 220 seconds).
