The Edwards 5532MHV Adaptatone® Millennium Remote speaker/amplifier has been designed for high decibel system operation when connected to the 5540M Central Tone Generator. Each speaker/amplifier operates directly from local power sources, making it possible in a single system to connect the remote speaker/amplifiers to local power sources of different voltages. The 5532MHV-485Y6 is designed to be connected to RS485 networks, allowing full signaling communication control. Adaptatone® Signaling Systems are designed for industrial applications calling for high decibel output and microprocessor reliability combined with simultaneous signal delivery over all speakers included in the system. Typical applications include: emergency warning systems, plant evacuation alarms, security intrusion sirens, process monitoring, shift start-and-dismissal horns and paging signals.
