FEATURES
CommCenter® Model 300MB broadcasts pre-recorded voice messages, melodies, tones and signals over SelecTone® and public address systems. Model 300MB replaces outdated loop tape units with superior, high-quality audio playback. Model 300MB is remotely activated via contact closures.
Melodies, voice messages, tones and signals are available, including the pre-recorded CommCenter Standard Library and optional custom recorded messages. Units can be interconnected for greater message capacity.
CommCenter’s digital messaging capability is ideal for emergency evacuation announcements. Clear, concise, predetermined instructions can be broadcast over a SelecTone or public address system. The CommCenter’s pre-recorded melodies can convey the status of a process or machine without interrupting the flow of production in surrounding areas.
